Suggested Retail Price
Eastman Kodak's "EasyShare" line of digital cameras have consistently impressed me as living up to their name, being one of the most unfailingly easy to use line of digicams out there. One of the latest additions to the line is the EasyShare DX4530, a 5-megapixel, 3x-zoom digicam bringing really large image sizes to the point and shoot market. Very similar to the earlier DX4330, the new 4530 offers the same basic features, but with a larger 5.0-megapixel CCD for higher resolution.
The Kodak EasyShare DX4530 is very much a pure "point and shoot" camera, as it offers the user very little in the way of exposure adjustments or flexibility, but manages to capture surprisingly good images under a variety of conditions. Besides being easy to use to take photos with, the Kodak 4530 also mates with their optional 4000-series "dock," for easy downloading of images to your computer, and built-in charging of NiMH batteries.
Kodak's EasyShare line of digicams has consistently proven one of the most user-friendly series on the market, with simplified operation and the convenient compatibility of the EasyShare camera docks for easy image downloading. Debuting with a 5.0-megapixel CCD at a surprisingly low price (just under $400 at the time of its introduction in mid-summer, 2003), the EasyShare DX4530 looks a lot like the rest of the EasyShare line of digicams. Compact, curvy, and similar in style to a traditional point-and-shoot 35mm film camera, the DX4530 measures only 4.3 x 1.5 x 2.6 inches (110.5 x 39.0 x 66.0 millimeters). The camera's all-plastic body makes it light weight as well, at 9.2 ounces (261 grams) with the battery and memory card. There'll thus be little excuse for leaving it behind. The DX4530 squeezes into larger shirt and coat pockets, and comes with a wrist strap for carrying. The camera's compact design includes a retractable lens, protected by a removable plastic lens cap (a tiny strap tethers it to the camera body so you won't lose it). Though exposure features and overall setup are similar to previous EasyShare models (most notably the DX4330 model), the DX4530 boasts a larger, 5.0-megapixel CCD for capturing high resolution, print quality images, as well as smaller image sizes better suited for distributing via email.
The DX4530 is equipped with a 3x optical zoom lens, equivalent to a 38-114mm zoom on a 35mm lens. - This is a range from a moderate wide-angle to a moderate telephoto. A set of filter threads around the inside lip of the lens barrel accommodates a set of Kodak-manufactured accessory lenses, enhancing the camera's wide angle and telephoto capabilities. The camera's autofocus mechanism uses a multi-zone system that "finds" the primary subject in the middle of the frame that's closest to the lens, highlighting the active AF area in red brackets on the LCD display. Though automatically controlled, the DX4530 has a maximum aperture ranging from f/2.8 to f/4.8, depending on the zoom position. Normal focus ranges from two feet (0.6 meters) to infinity, with a Macro setting for more close-up shooting. In Macro mode, focus ranges from 2.8 to 28 inches (7 to 70 centimeters), depending on the zoom position. A Landscape shooting mode fixes focus at infinity, for distant subjects and scenery. In addition to the 3x optical zoom, the DX4530 also offers 3.3x Advanced Digital Zoom, which effectively increases the camera's zoom capabilities to 10x. Keep in mind though, that digital zoom decreases the overall image quality, since it only enlarges the center pixels of the CCD image. For composing images, the DX4530 offers both a real-image optical viewfinder, and a 1.8-inch color LCD monitor.
Exposure remains under automatic control on the DX4530 at all times, although the camera does offer a Long Time Exposure mode for longer exposures up to four seconds. The Mode dial on top of the camera controls the operating mode, offering Movie, Auto, Sports, Night, Landscape, and Macro modes. While Auto mode is best for general photography conditions, the remaining preset modes are tailored to specific shooting situations such as night portraits in front of bright cityscapes or capturing the action of a little league game. In Sports mode, the camera uses faster shutter speeds (from 1/1,700 to 1/30-second) to "freeze" action. Night mode optimizes the camera for darker portraits and scenes, automatically combining the flash with a slower shutter speed to let more ambient light in to balance the image (you can also cancel the flash, for available-light night scenes.) Shutter speeds in Night mode range from 1/30 to 1/2-second, so you'll need to switch over to Long Time Exposure mode for longer shutter times, out to a maximum of four seconds. Landscape mode fixes focus at infinity, for capturing subjects more than 57.4 feet (17.5 meters) away from the camera. Finally, Macro mode adjusts the focus range for close-up shooting.
The DX4530 employs a Multi-Pattern, matrix metering system, which bases the exposure on several light readings taken throughout the frame, taking into consideration subject contrast as well as overall brightness. Although you can't adjust the aperture, shutter speed, or metering mode (apart from the Long Time Exposure mode), you can increase or decrease the overall exposure through the Exposure Compensation setting under the Record menu. Exposure Compensation adjusts the image from -2 to +2 exposure equivalents (EV) in half-step increments. White balance also remains under automatic control at all times, but the DX4530 uses Kodak's proprietary Color Science technology, which produces an accurate color balance under a surprising range of light sources. (I continue to wonder why other manufacturers can't manage to do as good a job with their auto white balance settings as Kodak does.) ISO remains under automatic control as well, but varies from 130 to 200 equivalent settings, depending on the light level. The built-in flash is effective from 2.0 to 11.2 feet (0.6 to 3.4 meters) depending on the zoom position, and features Auto, Fill, Red-Eye Reduction, and Off operating modes. A 10-second Self-Timer mode provides a delay between the time the Shutter button is pressed and the shutter actually opens, so that you can get into your own shots.
In addition to the range of still photography modes, the DX4530 also offers a Movie recording mode for capturing moving images and sound, at an image size of 320 x 240 pixels. Recording stops and starts with a full press of the Shutter button (you can also hold it down), and the full length of recording time appears in the LCD monitor. Movie lengths depend on the amount of memory space available. In an interesting and useful departure from the norm, the 4530's self-timer function works in Movie mode as well as for still pictures. Through a menu option, you can program the 4530 to record fixed-length movies of 5, 15, or 30 seconds when triggered by the self-timer, or to simply begin recording when the timer runs out and run until either the memory card is full, or you stop the recording by pressing the shutter button again. (Note that the LCD display is turned off when the camera is running from the self-timer in Movie mode.)
The DX4530 is compatible with Kodak's EasyShare camera docks, which offers hassle-free image downloading. You simply put the camera into the dock (a plastic dock insert provided with the camera fits the DX4530 bottom to the dock) and press the Connect button on the dock. (Some camera kits include the EasyShare Camera Dock II as part of the bundle.) The dock station also serves as an AC adapter and in-camera battery charger (with Kodak NiMH battery packs). The DX4530 is also compatible with the recently-released Printer Dock 4000, which lets you print 4x6 snapshots directly from the camera. Built into the DX4530 are 32 megabytes of internal memory, but the camera also features an SD/MMC memory card slot so you can expand the camera's memory capacity. I highly recommend picking up at least a 64 or 128-megabyte card right away, given the camera's 2,580 x 1,932-pixel maximum image size. For power, the DX4530 uses either two AA-type lithium or NiMH batteries, or a single CRV3 lithium battery pack. For the best performance, I recommend keeping a spare set of batteries freshly charged at all times. See my Battery Shootout page to see which batteries currently on the market are best, my review of the Maha C-204F charger, my long-time favorite.

Like the rest of the EasyShare series of digicams, the DX4530 is a great choice for anyone looking for hassle-free shooting but good color, white balance, and exposure. Just about everything is automatically controlled, with great results, although the DX4530 does offer a few creative options for enhancing its performance. The camera features Kodak's very straightforward user interface, complete with clear, helpful feature descriptions, making it a good option for kids or novice users. With its no-fuss design, camera dock compatibility, and generous 5.0-megapixel CCD, the DX4530 does credit to the EasyShare name, providing good image quality and unbeatable ease-of-use at a low price.
Compact and reasonably small in size, the DX4530 measures 4.3 x 1.5 x 2.6 inches (110.5 x 39.0 x 66.0 millimeters), just small enough to fit into coat pockets and purses, and possibly larger shirt pockets. The DX4530 is light weight as well, thanks to its all-plastic body, at just 7.4 ounces (210 grams) with batteries and SD card loaded. A wrist strap comes with the camera, but a soft carrying case would be a good idea for protecting the camera when traveling.
The DX4530's front panel features the telescoping lens, which takes up almost the entire right side, surrounded by a thick, plastic lip complete with filter threads for accessory lenses. The lens extends outward about another 3/4-inch when the camera is powered on. Also on the front panel are the optical viewfinder window, flash, self-timer lamp, light sensor, and tiny microphone. A gently-sculpted hand grip on the side of the camera features just enough of a ridge for your fingers to cling to as they wrap around the camera.
On the right side of the camera (as viewed from the back) is the SD/MMC memory card and USB compartment, as well as the Video Out jack. A hinged, plastic door protects the compartment, and opens from the back panel. Below the card slot is the USB jack, for connecting the camera directly to a computer. A shiny, silver eyelet is also on this side of the camera, for attaching the wrist strap.
The opposite side of the camera features the DC In jack, covered by a flexible flap. A small eyelet just below the jack compartment attaches the lens cap strap.
The Shutter button, Mode dial, Flash button, and speaker are all on the DX4530's top panel.
The rest of the camera controls are on the rear panel, along with the optical viewfinder and LCD monitor. An indented thumbrest on the right side cups your thumb as you hold the camera, reinforcing the front handgrip. Above the thumbrest is the zoom rocker button. The Share, Delete, Menu, and Review buttons are laid out near the four corners of the LCD monitor. The Four-Way Arrow pad on the left side of the LCD monitor has a rubbery nub in the center that makes it easy to grip, and which also acts as the OK button. The optical viewfinder eyepiece is quite small, but has a fairly high eyepoint to accommodate eyeglass wearers (I could see the full view at a good distance from the camera). Next to the viewfinder is a small LED lamp, which lights or flashes to indicate camera status (such as when focus is set, flash is charging, etc.).
On the bottom panel of the DX4530 are the tripod mount, dock jack, and battery compartment. The plastic, threaded tripod mount is off-center and too close to the battery compartment for quick battery changes while working with a tripod. (I doubt that this will be of much concern to most users though, as the DX4530 is clearly designed for on-the-go shooting.) I generally prefer to see metal tripod sockets, but the small size and low weight of the DX4530 mean the plastic socket should hold up fine under normal usage. The battery compartment features a locking, hinged door, which slides forward to open. The dock connection jack is protected by a sliding plastic door, and connects the camera directly to the EasyShare docks for quick image downloading or printing.
As I've come to expect from Kodak's EasyShare digicam line, the DX4530 has a clear, easy-to-understand interface. The fully automatic exposure control and limited exposure options keep user exposure decisions to a minimum, although you can adjust a few variables such as flash mode and exposure compensation. The LCD menu system is short and simple to navigate, with the familiar Kodak design standard, and the Mode dial lets you change camera modes quickly. Given the simple interface and limited controls, you should be able to snap images right away, without much more than a glance at the manual.
The DX4530's display shows the center autofocus area along with currently-selected options for image size/quality, macro and flash mode, the number of images of the current size and quality that can be stored in the remaining space on the memory card. A battery icon also appears, reporting the approximate level of charge left. A half-press of the Shutter button highlights the AF area selection in red. (Pressing the OK button simply turns the LCD monitor on or off.)
In Playback mode, you can press the DX4530's multi-controller to zoom in or back out of an image, with a maximum enlargement of 4x. Through the settings menu, a more detailed information display is available, reporting date and time of capture and the image quality setting. (Sorry, I missed grabbing the zoomed-playback view for the screen shots above.)
Shutter Button: Located on the camera's top panel, this button sets focus and exposure when halfway pressed, and fires the shutter when fully pressed. In Playback mode, pressing this button returns the camera to the selected Record mode.

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, nobodies 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...
(Well, not quite "back to our regularly scheduled review..) - I've gotten so many emails about power issues for digicams, that I'm now inserting a standard notice in my reviews of all AA-powered cameras: Don't even *think* about using alkaline AA batteries in a digicam! Despite their being packed in the box with many cameras, they simply don't have the juice to handle typical digicam demands. Spend the $35-40 or so it takes to get a set (or two) of high-capacity NiMH rechargeable batteries and a good charger! The few dollars up front will save you literally hundreds of dollars in the long run, not to mention the hassle of wimpy batteries running out in the middle of the action. Buy two sets of batteries too, so one can always be in the charger, ready to go, and so have two sets available for longer excursions. Check out my Battery Shootout page for the latest in actual, measured performance of various AA batteries. Read. - Read my review of the Maha C-204F charger, to learn why it's my longtime favorite.

EasyShare DX4530 user reviews on PC PhotoREVIEW
See our sample pictures and detailed analysis here. The thumbnails below show a subset of our test images. Click on a thumbnail to see the full-size photo.
In keeping with my standard test policy, the comments given here summarize only my key findings. For a full commentary on each of the test images, see the DX4530's "pictures" page.
As with all Imaging Resource product tests, I encourage you to let your own eyes be the judge of how well the camera performed. Explore the images on the pictures page, to see how the DX4530's images compare to other cameras you may be considering.
- Color: Although the DX4530 offers only fully automatic
white balance, Kodak's Color Science technology does a superb job of producing
accurate color under almost any light source. I generally found very slight
color casts in the DX4530's images, but they were slight indeed, and it
did an exceptionally good job with the tough incandescent lighting of the
Indoor Portrait (with and without flash), as well as under my studio lighting.
The very slight pink cast produced attractive skin tones, and the camera
did a nearly perfect job in overall color rendition, handling even the notorious
blue flowers of the Outdoor Portrait test very well. Colors were bright
and vibrant, hue-accurate and appropriately saturated.
- Exposure: The DX4530 had a tendency to overexpose slightly
outdoors and under the studio lighting. The outdoor shots showed this the
most, particularly the outdoor house shot. Indoors, however, the camera
did very well, requiring a less than average amount of positive exposure
compensation at +0.3 EV. The camera's native contrast is somewhat high,
as it had a tendency to lose detail in highlights and plug the shadows when
dealing with harsh lighting, but this is frequently a tradeoff that's made
to achieve bright, appealing color.
- Resolution/Sharpness: The DX4530 performed very well
on the "laboratory" resolution test chart. It started showing
artifacts in the test patterns at resolutions as low as 800 lines per picture
height, in both horizontal and vertical directions. I found "strong
detail" out to at 1,300 lines, a very good performance. "Extinction"
of the target patterns didn't occur until about 1,550 lines.
- Closeups: The DX4530 captured a small macro area, measuring
2.52 x 1.89 inches (64 x 48 millimeters). Resolution was very high, with
strong detail in the dollar bill. However, the corners were very soft, blurring
the details of the coins and brooch significantly, more than seemed to be
accounted for by the shallow depth of field when shooting so close. The
camera's flash had a little trouble throttling down for the macro area,
although it couldn't really be blamed for the bright specular reflection
on the brooch. At the closest shooting distances, the camera's lens shadows
the subject area slightly in the lower left corner of the frame. (Overall,
plan on using external lighting for your closest shots with this camera.)
- Night Shots: The DX4530 normally operates under automatic
exposure control at all times, with a maximum shutter time of 1/2 second.
This would limit its low light capabilities quite a bit, but fortunately
there's a long-exposure mode, in which exposure times can be set manually,
out to a maximum of 4 seconds. If you don't mind fiddling a bit to find
the right exposure, the DX4530 can therefore deliver nice bright images
down to a limit of about 1/4 foot-candle (about 2.7 lux). This is roughly
a quarter of the brightness of a typical city night scene under average
street lighting, making the 4530 quite usable for photography after dark.
(You'll probably need to use it in its "landscape" mode though,
to set the focus at infinity, as the autofocus system won't be able to work
under such dark conditions. - That's why my low light test photos were poorly
focused.) In my testing, I found the color and noise levels surprisingly
good, even under very dim lighting conditions.
- Viewfinder Accuracy: The DX4530's optical viewfinder
was somewhat tight, showing about 85 percent frame accuracy at wide angle,
and approximately 84 percent at telephoto. The LCD monitor actually proved
a little loose, showing very slightly less of the framed area in the final
image. Given that I like LCD monitors to be as close to 100 percent accuracy
as possible, the DX4530's LCD monitor is close to perfect.
- Optical Distortion: Optical distortion on the DX4530
was less than average at the wide-angle end, where I measured approximately
0.5 percent barrel distortion. (The average among cameras I've tested is
on the order of 0.8%.) The telephoto end fared even better, as I measured
only one pixel of barrel distortion. Chromatic aberration was fairly high
though: There was a good eight or nine pixels of coloration on either side
of the target lines in the upper right-hand corner, although the color wasn't
too intense. (This distortion is visible as a very slight colored fringe
around the objects at the edges of the field of view on the resolution target.)
There's some softness visible in the corners as well, although it doesn't
extend too far into the picture area.
- Shutter lag and cycle time: With a full-autofocus shutter
lag ranging from 0.78 to 1.17 seconds, the DX4530 is squarely in the middle
of the range of the consumer digicams I've tested. (Which, by the way, is
way too slow IMHO, but that just seems to be where the bulk of the market
is right now.) Its prefocus shutter lag is 0.22 seconds, also about average.
Shot to shot cycle times are 3.13 seconds for its highest-quality images,
and 2.99 seconds for its lowest-quality ones, with a 6-frame buffer memory.
- Battery Life: The DX4530 does pretty well for a camera powered by only two AA cells. Using my standard reference of 1600 mAh rechargeable NiMH cells (true capacity, vs rated), the 4530's worst-case run time (capture mode with the LCD turned on) is about 80 minutes, on the short side of average, but not terrible. With the LCD off, its power drain drops to a very low value, and run time stretches to an exceptional 14 hours. As always, I strongly recommend purchasing at least a couple of sets of high-capacity NiMH batteries and a good charger. Kodak's optional EasyShare Dock 4000 comes with an NiMH battery pack and a built-in charger. (See my Battery Shootout for the latest ratings of high-power NiMH AA cells, or read my review of the Maha C-204F charger to see why it's my longtime favorite.)
