Canon EOS 400D Digital Rebel XTi Introduction
by Dave Etchells
and Shawn Barnett
Though it was still the hottest selling digital SLR on the market, the Canon Digital Rebel XT was due for an upgrade, and right on the expected 18 month schedule comes the EOS Digital Rebel XTi (called the EOS 400D overseas). The new Rebel XTi has a 10.1 megapixel sensor, a 2.5 inch LCD screen, and a new dust cleaning system; and like its EOS brothers, the Rebel XTi will work with a vast system of over 50 lenses and a wide array of accessories. It borrows a lot of other recent innovations from recent EOS cameras, including PictBridge printing enhancements, Picture Styles mode settings, and it and comes in at $100 less than its predecessor. More importantly, the Rebel XT maintains the high image quality we've come to expect from Canon's SLRs, from the Rebels to the 1D-series.

Canon Rebel XTi User Report
by Shawn Barnett
Similar in weight and size, much of the user experience with the Canon Rebel XTi is like the Rebel XT. They're both small digital SLRs with good heft and a solid feel. But there's more to like about the XTi, from the finish to the fit to the interface.
The silver paint, which I think they call "chrome" is a brighter silver, also more metallic looking. It looks garish to my eye, but I'm sure many will like it. Like Canon's legendary white lenses, the silver body should tend to get a little less hot in direct sunlight.
Grip. I'd have preferred a more dramatic increase in grip size, but I'm glad for the improvements that were made. For his part, Dave expressed vehement hatred of the Rebel XT's grip, but he was more pleased than I was with the subtle changes we both perceived in the XTi's grip. The changes aren't easily seen; it's more the hand that notices a change. First, there's more of a coarse texture to the grip surface. It also appears that they rounded the front slightly, where your two middle fingers rest, giving perhaps a millimeter or two of rise; then they re-tapered the grip's shape to have slightly more fullness left to right, with just a little more material rounding out toward the right. What I don't like is that where the Rebel XT's grip met the camera body (the side toward the lens) at a stronger right angle, the Rebel XTi's grip is more rounded, preventing me from wedging my fingertips into the corner. Pentax recently made the opposite change in their redesign of the *istDL to the K100D, and I prefer it. My standard form of carry is either up by the chest holding the lens in my right or left hand, or down to the side with my hand around the grip. I use straps only very occasionally, and I hate them the whole time, so a camera's grip is very important to me.
Overall, I'd say the Rebel XTi's grip is improved. I still have to curl my pinky finger under the battery compartment, because the grip isn't tall enough. Even my wife, who liked the XT's grip, wasn't as enthusiastic this time. She liked how light the camera was, but not the inside of the grip, nor that her pinkie finger had to curl around the bottom to allow her index finger enough room to rest on the shutter. The 30D grip felt more sturdy to her. "I think I'd get tired holding the XTi all day," she said. It's probably a non-issue if you use a camera strap, though, as most do.
Attaching the BG-E3 battery grip extends the length of the gripping surface, making a world of difference. Even without the BG-E3, the front grip is enhanced by an improvement in the thumb grip on the back. Both the Rebel XT and the 30D have a single large bulge in the top right corner that gives a decent counter to the front grip. The Rebel XTi adds a smooth curving ridge that runs down from this bulge, adding extra support and some sense of comfort. There's also a soft rubber pad right where the thumb needs it most, making for extra traction. Despite my quibbles, the combination of minor enhancements does make for a more secure and comfortable hold so you can focus on getting a great shot.
The Rebel XTi's larger screen has dictated a few changes to buttons, with the five left buttons shrinking again to small round buttons instead of the larger reverse-D shaped buttons of the Rebel XT. These new buttons have a soft, but detectable click. Since there's no longer a monochrome status display, the LCD illumination button is gone.
Upper left of the Rebel XTi's 2.5 inch LCD is something that surprisingly wasn't included on the Rebel XT: the now almost ubiquitous Print/Share button. First introduced on Canon's digicams, the first SLR to receive this feature was the over-$3,000 Canon EOS 5D. The button glows blue when connected to a compatible printer or computer via a USB connection, meaning you can begin printing or transferring images right away. It took a little time for my computer (an iMac G5) to wake up and get all the pieces in place for the first time, but after that it worked just fine, and transferred images very quickly via the USB 2.0 connection.
Just above the LCD and below the optical viewfinder are the IR emitter and sensor that detect the presence of your eye or other object (such as your stomach if you have the camera on a strap). This tells the camera that the monitor no longer needs to be on, and prevents glare from interfering with the light coming through the viewfinder. It does not start up the autofocus system as we've seen on the Sony A100; Canon has opted to leave that job to the shutter button. The advantage to that decision is that while you move the camera around, you won't be turning the AF system off and on repeatedly, which can wear on the battery.
External tweaks. There are other changes that are mostly cosmetic, like the larger Canon logo on the front of the camera, and a slightly redesigned mode dial on top. The latter looks more machined on top and has a slightly more useful knurl around the outside. The shutter button is also black instead of silver on the black model, to more closely resemble the rest of the black body EOS models. The five-way navigator buttons on the back are also black on the black body. The corresponding items on the silver body are now silver, and many of the accents (the mode dial and power switch, the rubber thumb rest, the left side panel and its rubber door, and the lens release button) are dark gray.
The design of the Rebel XTi is very similar to the XT, but its lines are slightly more organic, looking more mature and sturdy. Those few enhancements noted above, along with the better paint make the Rebel XTi look more professional.
Staying standard. With most other recent consumer SLRs switching to SD cards, I fully expected Canon to follow suit by switching to SD in the Rebel XTi, but I was pleased to see a nice big CF door in place. It appears nearly identical to the Rebel XT; perhaps a little longer due to the new rear grip addition, but functionally the same. In general, you're still able to buy larger cards for CompactFlash because the card format is larger and can fit more chips for less money. I'd prefer the choice of both, for users with different needs, but that adds money to the bottom line; and remains a feature of the far more expensive Canon 1D-series.
Firing it up. Wrapping my hand around the improved grip, the hold is sturdier. I can use my index finger to reach back across the top deck and flip the camera on. It's a little less comfortable than on the Olympus E-500, but still quite possible. The green lamp on top flashes to life, as does the LCD on the back. The gray status display comes on, showing the current settings. In the lower right corner, a little rectangle appears with animated sparkles for a second, then the estimated number of frames available on the card appears (when you turn the camera off, a black screen comes up with the same animated sparkles as shown at right). I can bypass the cleaning process if I'm in a hurry by half-pressing the shutter button; otherwise, it takes about a second to complete the cleaning process. I noticed no sound while cleaning initially, but since I've had an opportunity to try it in a quieter room, I do hear a series of pulses, then a high-pitched ringing sound. It's not really distracting, though, and you have to listen for it. (For more on Canon's impressive new sensor cleaning and dust reduction system, see our expanded explanation under the Optics tab.)
Bigger LCD. The Canon Rebel XTi joins the lion's share of current digital SLRs with its larger, brighter 2.5 inch LCD with 230,000 pixels. Its viewing angle is 160 degrees, to help you show off your images to more people than the XT allowed. Like many other consumer SLRs, the Rebel XTi's color LCD stays on to serve as status display. It uses more battery, but the new Status Display is a lot better than the old monochrome LCD, mostly because there's more room to display the camera's many potential settings. On the XT, you had to look through the viewfinder to set the AF point, or use the cryptic number display on the monochrome LCD; but with the XTi, you need only press the AF point selector button, look at the back of the LCD -- or through the viewfinder -- and use the four-way nav buttons to select your AF points. At rest, you can double check the setting just by glancing at the Status Display again, where it is permanently displayed.
Other EOS cameras with a top Status Display require you to press a button, tilt the camera toward you, and turn the dial to make your changes (or look through the viewfinder). On both the old XT and the new XTi, all the buttons are on the back with the display, and most items can be changed with the Five-way Navigation buttons. The simple, clean gray and purple screens that come up to change common items like ISO and AF Mode are unimpressive at first, but once you use them a few times, the advantage of such a minimalist approach is clear, because all you see is what you're after.
The battery icon has been improved a little, adding an additional stage to the formerly inadequate 2-stage battery icon of other EOS cameras. You could say it was a three stage icon, but flashing an empty battery outline to indicate empty is too little too late. It's good to have a little more advance warning with an additional bar.
New AF module. It doesn't stand out quite as much as the higher resolution and the anti-dust system, but the Rebel XTi's AF sensor upgrade is significant, because it's the same sensor used in the 20D and 30D. Shortly after completing the Rebel XT review, I spent a lot of time with it, comparing it to the Canon EOS 20D in all kinds of shooting situations. It became clear that the 20D was significantly faster in low light than the XT or the original Digital Rebel. It wasn't just the 9-points of the 20D vs the 7-points of the XT, it was just far better at analyzing a scene and deciding where to focus.
As a torture test, I grabbed both cameras and asked my son to run around in a lamp-lit room while I tried to snap his picture. The XT hardly got a shot off, compared to the 20D which more often than not locked and fired time after time. I've done the same test with other digital SLRs, and the Rebel XT beats them--but the 20D was even better. My tests with the shipping version indicate that the Rebel XTi is roughly equal to the 30D in low light.
Anyone looking at a digital SLR to take pictures of the kids at play or sport needs to know how important good low-light AF performance is to a good experience, since a good many sports are done indoors in low light, or at night, and the players are moving at high speed. Though it's still very difficult to get good sports shots with any camera, you're more likely to get something good if you start with a camera like the Canon Rebel XTi.
The Rebel XTi's viewfinder does not have the flashing red boxes that the 30D does; instead it has small red dots that light up in the middle of the boxes. Depending on the background, sometimes one is better than another, but I think both of these Canon AF indicators are easier to see in more lighting situations than most other solutions on the market.
Viewfinder. Okay, so now I've turned the Rebel XTi on and checked the settings. Now I hold it up to my eye and the IR sensor turns off the display. I haven't tested it yet, but apparently sunglasses could keep the sensor from seeing its signal returned. Of course, glare from the sensor is unlikely to bother you much if you're in light bright enough that you're wearing sunglasses. According to the remarkably complete white paper on the Rebel XTi, some fluorescent lamps could also turn off the monitor if placed too close to the source. So don't do that.
Peering through the viewfinder, it's a little disappointing that the magnification hasn't been improved as we've seen on the Nikon D200 and D80. Greater magnification is just more comfortable, and easier to verify focus. That hasn't stopped me from getting great shots with the existing magnification, however, so take it for what it's worth. AF points are arrayed in a diamond pattern, which Canon says helps improve subject tracking. My son has demonstrated that. The LED numbers for Shutter Speed and Aperture seem a little larger, and there are two new icons, a Flash Exposure lock indicator and a White Balance adjustment indicator. With my glasses on, the viewfinder picture is not quite complete, with vignetting around the corners. I have to press my glasses close to my face and up against the rubber guard to see the full frame.
If I'm in manual mode, I can adjust Shutter speed with the Main dial behind the shutter button, and press the Av button to adjust aperture, all without taking my eye from the viewfinder. The little arrow beneath the exposure level indicator responds to show levels like an old match needle. Pretty simple, and a very common method employed on this range of digital SLRs. This one puts my thumb right up against my cheekbone, but it's not bad. Slightly higher-end cameras have two wheels to control both variables in manual mode, but these lower-end cameras save a little on the bill of materials by assuming that most users will use one of the full- or semi-automatic modes.
Squeeze. With everything set, I half-press the shutter and the Rebel XTi tells me which AF points it's selected. If I don't like the selection, I can press again, and it will very often choose another set of points. This actually works very well most of the time, but when I'm doing important work, or facing an odd lighting situation, I switch to the center AF point on almost every camera. If I'm feeling lazy, I just keep hitting that shutter button until I'm satisfied.
Then I slowly squeeze the shutter button all the way down. The shutter sound is pretty well identical to the Rebel XT. A snap with a winding noise. It's not film that's being wound (obviously), just the shutter spring being reset by a small motor. Luke (our test wizard here at Imaging Resource) thinks I'm nuts, but I still suspect that they chose this winding motor on purpose, because that's what people expect SLRs to sound like (ever notice in the movies that even the smallest point and shoot camera sounds like it has a big professional motor drive?). The original Digital Rebel and EOS 20D didn't make this sound--at least not loudly--nor did the EOS 1D, but the Rebel XT and 1D Mark II certainly made quite the whirring sound. The XTi still has it.
When in AI Servo autofocus mode, the Rebel XTi doesn't need to lock focus like the XT and 20D did before the shutter will fire. Just press it all the way and it will capture whatever it sees. Another feature that appeared on the 30D is that the shutter button no longer needs to be released completely to make a follow-up shot. With the 20D and Rebel XT, you had to release the shutter button completely and the camera went through another AF cycle before the shutter could be released again. With the XTi, you can keep shooting more rapidly if you're satisfied that the focus is just fine. You just release the shutter halfway rather than all the way, and press again to capture subtle nuances in a scene.
Playback's enriched. A few enhancements to the Canon Rebel XTi and EOS 30D are good enough that they're worth the upgrade from the perfectly decent Rebel XT and EOS 20D models. One is a special auto-rotation mode. I hate auto rotation. You have this big rectangular screen that matches the orientation of the sensor, and you're going to rotate the image on the camera so that it's smaller and harder to see? I'd rather just turn the camera; after all, it wasn't hard to turn the camera when I captured the vertical shot, so I can easily do it again to view it. On the other hand, if I've taken a lot of shots, hand-rotating the vertical ones when I copy them to a computer is a bit of a pain. The Rebel XTi will let you have the best of both. Auto rotate can either rotate the images on the camera and the computer, or leave them as captured on the camera and rotate them on the computer. That time savings alone is worth the upgrade if you take enough pictures.
It's important to note that the new Auto Rotation works well if you use Canon's software, but many applications can get confused and rotate the image again. For my own sanity, I've opted to leave Auto Rotation off when I shoot with the Rebel XTi.
Another feature to come over from the 30D and higher cameras is the option of displaying either luminance or RGB histograms. The latter can often reveal an error in white balance if all three colors do not seem to be balanced across the histogram's range.
Finally, because the Rebel XTi's display is on while the camera's on, the name of the INFO button has been changed to DISP, for Display. The difference is that INFO regulated the amount of information that showed up primarily in playback mode, but the Display button can also turn the Status Display off to save battery when you still want to keep the camera's power switch on and the camera ready.
The XTi offers an expanded feature set that matches or exceeds the capabilities of the 30D. Here's a list of the printing capabilities added since the Rebel XT:
- 35-image "contact sheet" index printing
- Single-image prints with EXIF shooting information
- 20 image contact sheets with EXIF data
- Red-eye reduction function
- Face brightening correction function
- Additional supported paper sizes (4 x 8", 10 x 12", 8 x 10", 14 x 17")
- Improved printing effects (Natural, Natural M, B/W, Cool Tone, and Warm Tone added)
- Adjustment of printing parameters
- Addition of supported paper (Fine Art, Photo Rag, Super Photo paper)
Improved buffer depth. The Rebel XTi can also shoot more pictures than its predecessor in continuous mode. I picked a simple photograph hanging on a beige wall and managed to fire off 34 shots in Large Fine JPEG mode. That's more than they're stating, and we're pretty sure we have a target or two that could make the Rebel XTi capture fewer than the 27 Canon-estimated shots before the buffer is filled. But they're rightly quoting an average, since the size of a JPEG shot can vary widely based on the relative compressibility of the subject. Since RAW files are also losslessly compressed, their sizes vary too, but it seems to stick more closely to 10 frames to fill the buffer in my informal shooting (our test results show it at between 9 and 12 frames).
Battery. The XTi's battery is the same as the XT's, the NB-2LH, but because of the larger display, its function as a Status display, and the new self-cleaning system, battery life is reduced. You can expect 500 images at room temperature (without flash) and 360 shots with 50% flash usage. At freezing temperatures, that expectation goes down to a still-respectable 370 and 280 shots without and with flash.
Competition. The Rebel XTi's obvious competition is the Canon 30D, the Nikon D80, and the Nikon D40. Sure, the Olympus E-500, Sony A100, and Pentax K100D are also contenders, but those comparisons are for a separate article. Since many XTi shoppers will be comparing the camera to the Nikon D40, Nikon D80, and Canon EOS 30D, I've snapped some images of the XTi next to all three so you can get an idea of the size differences. For the record, I do prefer the D80 and 30D grips, but that might not be a huge consideration for you if you plan to use a camera strap to carry the camera.

First Test Shots! September 8, 2006, 12:33 am. We can finally post some test shots for the Canon Digital Rebel XTi. We ran it through our full suite of new test targets, which tells a pretty good story about this new 10.1 megapixel camera's capabilities. The lens, however, is not really equal to the high resolution of this camera, so tonight I took some indoor gallery shots with the Canon EF-S 60mm f/2.8, a very sharp lens. I wasn't able to journey outdoors due to the bad weather today, but hopefully tomorrow will offer better light, and I'll be able to post quite a few more. For now, here are a few shots of my personal little models, who are very good sports when dad has to test a new camera. To see all the full set of Multi Target and Still Life shots in addition to these three, click on the Samples tab and select Thumbnails (or click here). To get the RAW versions, you'll need to click on the links below. Beware: they are between 11 and 13 megabytes each.
NOTE: The Safari browser cannot download the CR2 files for some reason; please use Firefox or another browser.
More images posted. September 8, 2006, 3:14 pm; updated September 11. The weather did cooperate, and I managed to get a few decent gallery shots around a nearby town today. I plan to head out for more, mostly because I've been dissatisfied with the 18-55mm kit lens that Canon sent along. It's not a new lens that came with the body, but a well-used one. The first rack of Multi Target and Still Life shots were dramatically soft in the corners, far more than I remember from other Digital Rebel cameras. It could be the higher-res sensor showing the insufficiency of the lens, but this looks worse to me. The galleries I shot show this quite dramatically around the edges, and chromatic aberration is nasty even toward the middle. The 60mm shots I took last night and today are so much better that I need to grab the other 18-55mm we have around here, which we used to test the Rebel XT way back and test that.
Meanwhile, we've reshot the full target set of Still Life images with the Canon EF 100mm f/2.8 Macro. Some readers have pointed out that we shot the Nikon D80 with the Nikon 105mm f/2.8 rather than its 18-135mm kit lens, which is a good point. We'll be shooting both with the kit lens and with a benchmark lens if it's available.
Finally, for those comparing the Canon EOS Digital Rebel XTi to the Nikon D80, it had been brought to our attention that we shot the ISO series of the Still Life with the Nikon D80 at high contrast. However, on closer inspection, and after a reshoot of the camera, it has become clear that the D80 was set to Auto Contrast. Since both the D80 and the Rebel XTi are consumer cameras, we elect to leave it at that. You can see the results of the ISO 100 shots for analysis of contrast and compare it to the ISO 1,600 version to satisfy yourself about how much contrast might influence the image. We want to leave it to the D80 to decide how to set the contrast, since that's what most users will do.

Some may prefer Canon's approach to noise, because they can eliminate the blotchy chroma noise with some of the excellent noise fixing programs on the market. Some will prefer Nikon's approach, which just takes care of the noise and delivers more even color tones, despite the slight watercolor effect. Most won't notice a difference when the images are printed.
All of the artifacts I mention in both images are visible from about a foot away in 13x19 inch printed images, but not from arm's length; which is the closest most people get to such images. The XTi's somewhat softer images are better able to handle unsharp mask than are the noticably sharper D80 images, where unsharp mask enhances many of the smudgy artifacts.
It's clear that there are differences in the way the Canon XTi and the Nikon D80 deal with noise at ISO 1,600, but most impressive is that they both handle the situation very well. The 13x19 inch images we printed are surprisingly good. I think we can call the images from either camera unprecedented.
The Canon Digital Rebel XTi is an excellent take-anywhere all-purpose digital SLR, that can serve as a second camera for owners of Rebel XT, 20D, 30D, and 5D cameras who want to keep a second body with a different focal length strapped around their neck. I think serious photographers would do better with an EOS 30D for its stronger build and greater manual adaptability, but for just about everyone else, the Rebel XTi offers everything you need and more.

- EOS Digital Rebel XTi body (plus lens if purchased as a kit)
- Body cap (plus front and back lens caps if kit is purchased)
- Wide Strap EW-100DBII
- Battery Charger CB-2LW
- Battery Pack NB-2LH
- USB Interface Cable IFC-400PCU

- Camera case for protection
- Accessory lenses
It's easy to miss much of what's improved on the Canon Rebel XTi, mostly because it seems so cosmetically similar to the Rebel XT. But the real improvements are internal. Getting to 10 megapixels while maintaining that industry-leading image quality was quite an achievement, and it's the factor that keeps the Rebel XTi worthy of the word "compelling." Regardless of what you think of the grip or other elements, there's no question that the Rebel XTi is the one you want along when the image really matters.
The EF-S 18-55mm f/3.5-5.6 kit lens that we were so impressed with on the 6 megapixel Digital Rebel in 2003 is indeed showing its age; or at least the 10 megapixel sensor is now revealing that this truly is a kit lens. It's not going to make a bit of difference if you only print to 8x10, though, and it is a decent lens that's lightweight and versatile. I still use one on occasion. Most first-time buyers should get the kit first to see how it works for them. Then consider a longer zoom, a wider zoom, and a prime or two. Those brave individuals, or those who remember the good old days, might want to skip the kit lens and spend $80 on Canon's light and fast EF 50mm f/1.8. This lens will remind you why you love photography, as it delivers beautiful bokeh and excellent sharpness.
Ultimately, the Canon Rebel XTi is an improvement of an already superb camera -- the Rebel XT -- with Canon's latest and greatest innovations to make digital SLR photography more like you remember from the film days and more versatile to boot. For my money, the greatest improvement to the XTi is the addition of the 30D's autofocus array. More pixels, a bigger LCD, and dust reduction are welcome, but faster AF is the true benefit to the Rebel XTi, because you can get shots that you couldn't with the XT. Now I can say that Canon's flagship consumer camera has it where it counts: fast, accurate autofocus and the best imager you can get for the money. All the rest is gravy. The Canon EOS Digital Rebel XTi is a fine digital SLR, an obvious Dave's Pick, and an excellent choice for anyone wanting to improve their photography.
