Camera Overview
With its unique, vertical lens design, Minolta's DiMAGE Xt, like the DiMAGE Xt and X before it, has a tiny, extraordinarily thin all-metal body. The new model is slightly shorter, ever so slightly wider, and slightly thicker than its predecessor, measuring a mere 3.6 x 0.92 x 2.6 inches (92.2 x 23.4 x 67 millimeters) and weighing just 5.0 ounces (143 grams) including the battery and SD memory card, the DiMAGE Xt is one of the smallest multi-megapixel digicams on the market. With the extremely compact design, there's no excuse for leaving it behind, as the camera can tag along in even the smallest shirt pocket, or be quickly tucked into an evening bag or pants pocket. The unique "folded" optical design means that there's no wait for a lens to telescope out of the body when the camera is powered up, resulting in very fast startup and shutdown times. The sleek design includes a built-in lens cover which conveniently slides out of the way whenever the camera is powered on, eliminating any concern over misplacing a lens cap. An all-metal case is rugged and solid-feeling, and should withstand the wear and tear of daily use better than most cameras. The 3x zoom lens, combined with the full automatic exposure control makes the camera suitable for most common shooting conditions. The 3.2-megapixel CCD produces high resolution images for printing, as well as lower resolution images better suited for email.

The DiMAGE Xt has a 3x, 5.7-17.1mm lens, the equivalent of a 37-111mm lens on a 35mm camera. The autofocus covers a range from 5.9 inches (15 cm) to infinity. There's no separate macro mode, but the 5.9 inch close-focusing combined with a telephoto lens setting produces very good macro performance. Depending on the lens zoom position, the maximum aperture ranges from f/2.8 to f/3.6. In addition to the optical zoom, the DiMAGE Xt offers a 1.1 - 4.0x digital zoom, in increments of 0.1x. (Although I always remind readers that digital zoom decreases the overall image quality because it simply enlarges the central pixels of the CCD's image.) You can choose between the real-image optical viewfinder or the 1.5-inch, color TFT LCD monitor to compose images, although as usual, the LCD monitor provides the most accurate framing. (The optical viewfinder is unusually "tight", showing only 75% of the final frame area.) In playback mode, images can be enlarged up to 6x, as an aid to checking critical focus and framing.

Exposure is automatically controlled at all times, with only a few exposure options available. An On/Off button on top of the camera powers the camera on, and a Mode switch lets you select between Record and Playback modes. Thanks to the all-internal lens design, there's no need to wait for the lens to extend before you can shoot, so startup times are very short. (A bit under three seconds.) Most exposure options are controlled through the LCD's on-screen menu system, which offers very straightforward navigation. That said, you can control flash mode, exposure compensation, and the lens zoom externally, via buttons and controls on the camera's rear panel. Shutter speeds range from 1/1,000 to four seconds, though the chosen value is not reported to the user. (The maximum shutter time is twice that of the earlier DiMAGE Xi, making for much better low-light capability.) The right and left arrow keys on the camera's back panel control the Exposure Compensation, adjusting it from -2 to +2 exposure equivalents (EV) in one-third step increments. Sensitivity is adjustable to values of 50, 100, 200, or 400, with an Auto setting as well,that varies the ISO between 10 and 160, depending on the current light level. White Balance is adjustable through the settings menu, with options for Auto, Daylight, Cloudy, Incandescent, and Fluorescent light sources. The DiMAGE Xt's built-in flash operates in Auto, Red-Eye Reduction, Forced, Suppressed, or Slow Sync modes.

In addition to the basic exposure options, the DiMAGE Xt also offers a few extra shooting modes, controlled through the settings menu. In Movie exposure mode, the camera captures either 320 x 240-pixel or 160 x 240-pixel resolution moving images with sound, with duration limited only by the size of the memory card. (The included 16MB SD card should hold approximately 41 seconds worth of movies at the highest resolution, larger cards will store proportionately more.) A Self-Timer mode provides a 10-second delay between the time the Shutter button is pressed and when the camera actually takes the picture, allowing you to get into your own shots. For shooting fast action subjects, the DiMAGE Xt's Continuous Shooting mode captures a rapid series of images when you hold down the Shutter button, much like a motor drive on a traditional 35mm camera. Provided that there's enough space remaining on the memory card, the camera can capture up to 8 large/fine images, or over a hundred small/economy mode ones before having to pause to write the image data to the memory card. Details like image size and shutter speed can affect the shooting interval, but it averages approximately 1.3 frames per second. Finally, Audio Recording mode lets you record sound clips as long as 180 minutes (without an image), although the maximum recording time may also be limited by the amount of available memory card space. (A 16 MB memory card can hold about 30 minutes of audio.) The DiMAGE Xt also features a Voice Memo option, for recording short sound clips to accompany recorded images.

The DiMAGE Xt stores its images on an SD memory card, and a 16MB card accompanies the camera. (The camera also works with the slightly less expensive MMC cards.) Connection to a host computer for image download is via USB. The DiMAGE Xt is a "storage-class" device, which means that it doesn't require any separate driver software for Windows 2000 and XP, or for Mac OS 8.6 and later. (Download speed is also quite good, I clocked it at 548 KBytes/second on my Sony VAIO computer, running Windows XP.) The camera utilizes an NP-200 rechargeable lithium-ion battery for power, one of which is included with the camera, along with the necessary battery charger. While the DiMAGE Xt's battery life is better than most subcompact cameras, I still highly recommend picking up an additional battery pack and keeping it freshly charged. The optional AC adapter is also useful for preserving battery power when reviewing and downloading images, or when viewing images and movies on a television, via the supplied A/V cable.

Recommendation
The DiMAGE Xt is very small and compact. Its full automatic exposure control suits standard point-and-shoot operations, although the user does have a few options for brightening or darkening the image, or adjusting the color balance. The 3.2-megapixel CCD delivers good quality images, with enough resolution to make sharp 8x10 prints, and a low resolution option for email purposes. The DiMAGE Xt's tiny size and rugged case design make it a natural for "anywhere/anytime" photography. With its point-and-shoot appeal and ease of use, the DiMAGE Xt is perfect for novice users who simply want to take good pictures without getting too involved in the technicalities. Even sophisticated users will appreciate its exceptional portability and good picture-taking capabilities though. It'd thus do well as a "second camera" for enthusiasts, too.

Design
Like the DiMAGE X before it, the DiMAGE Xt has an amazingly thin, tiny case. Its sleek rectangular body shape and lack of protrusions make the DiMAGE Xt one of the most portable cameras on the market. Measuring just 3.6 x 0.92 x 2.6 inches (92.2 x 23.4 x 67 millimeters), the DiMAGE Xt fits just about anywhere, including the smallest of shirt pockets. Matching its diminutive size, the DiMAGE Xt is also very light weight at just 5.0 ounces (143 grams) including the battery and SD memory card. The secret to the DiMAGE Xt's compact design is its internally-mounted lens, which stretches vertically up the side of the camera rather than protruding from the camera's front. An internal prism reflects light from the subject down into the lens itself, almost like a periscope. The internal lens mounting means that there's no wait for the lens barrel to extend when you power up the camera, making startup times very quick. (Only about two seconds from power on to the first shot captured.)

The front of the camera holds the lens window, flash, optical viewfinder window, and self-timer lamp. A shutter-like, retractable lens cover protects the lens window whenever the camera is powered off, sliding quickly out of the way when the camera is turned on. Where the front of the DiMAGE Xi was very flat, the DiMAGE Xt has a little bulge on its right side (viewed from the front of the camera), that provides welcome purchase for your fingers. You can also see the horizontal row of five tiny holes, marking the location of the Xt's microphone. This was located on the top panel of the Xi, a change that makes sense, I think, providing better sound pickup from subjects in front of the camera.

The design of the DiMAGE Xt almost dictates a one-handed grip, something that took me a little getting used to. I realized that I almost always hold a camera with both hands, for a more stable shooting platform, minimizing camera shake. With the DiMAGE Xt, when I steadied the camera with my left hand, I initially often found myself putting a finger over the lens opening. Not a big deal, as I quickly got used to just using a couple of fingers on the bottom left corner of the camera, but something to watch for when you first start shooting with it.

On the right side of the camera (as viewed from the rear) is the combined SD memory card and battery slot, as well as the DC In power jack and a wrist strap attachment eyelet. A sliding door protects the battery/card compartment, with a few ridges on it to make it easier to open. Beneath the compartment door, the battery and SD card fit side-by-side. I thank Minolta for providing side access to both the battery and memory card slots, meaning you don't need to dismount from a tripod to change out either one. (Although I frankly doubt the DiMAGE Xt will be used on a tripod very often.) The combined A/V Out and USB jack has been moved to the right side of the camera on the Xt (it was on the left side of the Xi), protected by a little sliding door.

The opposite side of the camera is featureless, with no connectors or controls on it at all. This view of the camera shows the decal that illustrates the clever lens design Minolta is so justifiably proud of. Be reassured though, that the label can be easily removed after purchase, to result in a very sleek, elegant case design.

The DiMAGE Xt's top panel is sleek and smooth, with only a minor protrusion from the Shutter button. The power button is also located here, slightly recessed to prevent accidental actuation when the camera is slid in and out of pockets.

The remaining camera controls are on the back panel, along with the optical viewfinder eyepiece and 1.5-inch color LCD monitor. A single LED lamp next to the optical viewfinder reports the camera's status, such as when focus is set, when the flash is charged, etc. To the right of the viewfinder eyepiece is a small mode dial, with positions for still image recording, playback, movie/audio recording and setup. (This control replaces a two-position slide switch on the Xi, making for a more intuitive user interface.) To the right of the mode dial are three multi-function buttons, which access different settings in Playback and Record modes, also serving as navigation arrows in the menu system (the rocker button in the center serves for up and down menu navigation). The center button of this set of three controls the zoom lens in record mode and image zoom in playback mode. It also serves as the "OK" button in the menu system, when pressed straight down. Arranged under the LCD monitor are the Menu, QuickView/Erase, Display, and Flash buttons. A small speaker in the lower right corner plays back recorded sounds.

The bottom panel of the DiMAGE Xt reveals only the plastic, threaded tripod mount, slightly off center from the lens, and a set of three contacts that can charge the battery when the camera is parked either in the provided charger (there's a slot in the charger body that neatly fits the camera case) or in its optional accessory dock.

Record-Mode Display
In record mode, the LCD monitor displays the subject with a minor amount of overlaid information, indicating flash, white balance, ISO setting, the current size/quality setting, and number of images that can be stored on the remaining memory card space at the current size/quality. Pressing the Display button beneath the LCD once removes the information overlay, pressing it again turns the LCD off entirely, and pressing it a third time restores the default display. When you half-press the shutter button, a small dot appears in the lower right-hand corner of the LCD indicating whether the camera is focused (white dot) or not (red dot), and a "shaking hand" symbol appears above the focus dot if the shutter speed is slow enough that you'll need to be careful not to jiggle the camera during the exposure.


Playback-Mode Display
In playback mode, pressing the default image display shows the most recently captured image, with an information overlay showing the resolution and quality setting used, the date and time of capture, the file number, and the sequence number of the image among those currently stored in the memory card. Pressing the Display button once dismisses the information overlay, and pressing it a third time shows a set of six thumbnails. With an image displayed full-screen, pressing the zoom control in the "T" direction zooms in on the image in steps of 0.2x, up to a maximum magnification of 6x. At any magnification level, pressing the "OK" button (pressing the center of the T/W lever) switches you to scrolling operation, in which the left/right buttons and the T/W control let you scroll around the magnified image. Pressing the center of the T/W lever again returns you to zoom operation. The screenshot above right shows all the available display options in playback mode.

External Controls

Zoom Toggle Button (Up and Down Arrow Key): Centered between the Right and Left Arrow keys, this control adjusts the optical and digital zoom in any record mode. It also serves as the up/down control when navigating LCD menu choices. This button also serves as the "OK" button for confirming menu selections.

In Record mode, pressing and holding this button for a few seconds switches the camera from area autofocus (the default) to spot autofocus or back again.

In Playback mode, this button lets you zoom in on an image, as much as 6x. Once you've zoomed in on an image, pressing the center of this button switches to scrolling operation, after which up/down actuation moves your view up and down in the enlarged image. Pressing the center of the button again returns you to control of the playback zoom level.

In Playback mode, pressing the Display button displays or dismisses the same information display as in record mode. A third press switches to a 2x3 display of thumbnail images for rapidly reviewing photos in the camera.

Recommended Software: Rescue your images!
Just as important as an extra memory card is a tool to rescue your images when one of your cards fails at some point in the future. I get a lot of email from readers who've lost photos due to a corrupted memory card. Memory card corruption can happen with any card type and any camera manufacturer, nobody's immune. A surprising number of "lost" images can be recovered with an inexpensive, easy to use piece of software though. Given the amount of email I've gotten on the topic, I now include this paragraph in all my digicam reviews. The program you need is called PhotoRescue, by DataRescue SA. Read our review of it if you'd like, but download the program now, so you'll have it. It doesn't cost a penny until you need it, and even then it's only $29, with a money back guarantee. So download PhotoRescue for Windows or PhotoRescue for Mac while you're thinking of it. (While you're at it, download the PDF manual and quickstart guide as well.) Stash the file in a safe place and it'll be there when you need it. Trust me, needing this is not a matter of if, but when... PhotoRescue is about the best and easiest tool for recovering digital photos I've seen. (Disclosure: IR gets a small commission from sales of the product, but I'd highly recommend the program even if we didn't.) OK, now back to our regularly scheduled review...

NOTE: that these are big files, so be aware that (a) they'll take a while to download, and (b) they'll chew up a pretty good chunk of bandwidth on us. (Read the "support this site" blurb at the top the carrier pages, and think about it while you're waiting for the images to download.

NOTE TOO: Some browsers have difficult with very wide images, and distort them a lot when they display them. (I don't know about others, but IE 5.0 on the Mac definitely does this. If the full-sized images appear to be stretched horizontally, you may need to just download them to your hard drive and view them in an imaging application, or possibly try another browser.)

Test Results
As was the case with the DiMAGE Xt before it, I was pleasantly surprised by the quality of the images from the DiMAGE Xt. See the DiMAGE Xt's sample pictures page for the full results of my testing, but meanwhile, here's a summary of my findings:

• Color: Color from the DiMAGE Xt was generally very good. Colors were accurate and properly saturated in all my test subjects, and the camera did a better than average job with even very dim incandescent lighting indoors. The white balance system left slight color casts in the images shot under incandescent lighting, but for the most part much better than most cameras I test under that light source. Color outdoors was very good as well, although I noticed a slight tendency toward excessive warmth in Caucasian skin tones. - The color bias was fairly slight though, generally within the range of what I'd consider acceptable.
  
  
• Exposure: Like the DiMAGE X and Xi before it, the DiMAGE Xt did pretty well in the exposure department. It's a little prone to losing highlight detail in contrasty scenes under sunlit conditions, but not more than I'm accustomed to seeing in many other digicams. As with the Xi before it, the biggest surprise I found was how well it did under even fairly dim indoor shooting conditions, where it could produce sharp, well-exposed images even under rather inadequate living-room lighting. I did find though, that it needed a fair bit of positive exposure compensation in interior shots, but that could largely be a consequence of the large expanses of white walls in most of my indoor shots. The flash also did a very good job of filling in the shadows without blowing out the rest of the images, and the slow-sync exposure mode produced a very appealing balance between room lighting and the onboard flash. Very nice.
  
  
• Resolution/Sharpness: Like most subcompact cameras, the DiMAGE Xt's were just a little soft when compared with the best full-sized three-megapixel digicams. It does show a fair bit of softness in the corners of the frame though, and there's some chromatic aberration present in the corners as well, more of both than I like to see.
  
  
• Closeups: The Xt captured a surprisingly tiny macro area, at 2.1 x 1.6 inches (40 x 53 millimeters). Resolution was very high, with strong detail in the coins and brooch. The dollar bill was a bit soft, likely due to the very shallow depth of field in macro shots like this one: The camera obviously focused on the surface of the brooch, where you can see very crisp detail. As is often the case in digicam macro shots, the corners were softer here, with the softness extending down the entire left and right sides of the frame. Color was pretty good, but the Xt's flash had trouble throttling down for the macro area, blowing out the image on the right side of the frame. Plan on using external illumination for the closest shots, but overall, the Xt is an excellent macro performer.
  
  
• Night Shots: Minolta boosted the maximum exposure time of the Xt to four seconds, which helps a good deal with low-light exposures. As a result, the Xt did quite well all the way down to the 1/16 foot-candle (0.67 lux) limit of my low-light test. An automatic noise-reduction feature keeps image noise under control, even with fairly long exposures at high ISO. On the downside though, the Xt had some trouble focusing at the darkest light levels, producing soft focus at light levels below 1/2 foot-candle, and it lacks a manual focus option to overcome this. (Either a manual focus option, an AF-assist illuminator or both would be quite welcome.) Still, 1/2 foot-candle is about half the brightness of a typical city street scene at night, so for most purposes, the Xt will do fine under available light.
  
  
• Viewfinder Accuracy: One of my biggest gripes with the DiMAGE Xi persists in the Xt: Its optical viewfinder is very tight, showing approximately 75 percent frame accuracy at wide angle, and about 74 percent at telephoto. The LCD monitor proved much more accurate, though actually just slightly loose, showing slightly more than 100 percent of the final image area. Given that I like LCD monitors to be as close to 100 percent accuracy as possible, the Xt's LCD monitor performed pretty well here, but I'd *really* like to see a more accurate optical viewfinder.
  
  
• Optical Distortion: Optical distortion on the Xt is higher than average at the wide-angle end, where I measured approximately 1.0 percent barrel distortion. The telephoto end fared only a little better, as I measured a 0.5 percent pincushion distortion. (Typical cameras I test show about 0.8% barrel distortion at wide angle (still way too much, IMHO), and 0.3 percent or less pincushion at telephoto.) There's some fairly noticeable softening in the corners (particularly on the left side of the image), coupled with some chromatic aberration, more of both than I like to see. As excellent a camera as the Xt is, there were obviously some tradeoffs that had to be made in the lens, with sacrifices made in resolution and distortion in the corners of the frame.
  
  
• Battery Life: Like most subcompact digicams, the DiMAGE Xt's battery life is a bit limited, although it seems to be slightly improved relative to that of the Xi model. In its worst-case power drain mode (record mode with the LCD enabled), battery life is only about 72 minutes, extending to about 117 minutes in playback mode. The real plus though, is that the camera takes almost no power in capture mode when the LCD is turned off. - It's a shame that the optical viewfinder isn't more accurate, as that'd make it more feasible to shoot with the LCD off, greatly extending battery life. As always, despite the excellent performance with the LCD turned off, I still strongly advise purchasing a second battery when you buy the camera.
