computer and communication: Digital Photography Review : Pentax K2000

For those looking for an entry into digital SLR (D-SLR) photography, the $599.95 (direct) Pentax K2000 is a great choice at a great price. This 10.2-megapixel camera performs quite well in well-lit outdoor shots, where its captures are just as sharp as those produced by the 12.1MP Panasonic Lumix DMC-G1 or the killer 12.3MP Nikon D90. The only area in which the Editors' Choice Canon EOS Rebel XSi outperforms the K2000 is shooting without a flash in low-light conditions. In these situations, the K2000's pictures tend to be grainy. This Pentax, though, has plenty of entry-level appeal thanks to its Help button, which acts as an onboard users' manual.

The K2000 is comfortable to hold and has a traditional SLR look-and-feel. Its 3.6-by-4.8-by-2.7-inch (HWD) body is available in either black or white (the latter is a camera-color rarity). With the included lens attached, the camera weighs 1.7 pounds. The controls are straightforward and are consolidated on the right-hand side of the camera. Most buttons are labeled with large, bold, uppercase text like MENU and INFO. Inside, the camera uses a CCD sensor and shoots through a 3X optical zoom wide-angle 18mm to 50mm lens (35mm equivalent: 27mm to 82.5mm) with corresponding f-stops at f/3.5 to f/5.6. When later analyzed through the Imatest (www.imatest.com) testing suite, the lens produced just a hair of pincushion distortion at its widest and telephoto position; no matter what the subject, though, my real-world photos never appeared warped.

Near the power switch on top of the camera is the K2000's Help button, which is labeled with a question mark. This feature is a real boon for those new to D-SLRs. Simply tap Help and then any other button or dial on the camera, and a short description of that function (and often a one-line tip) is displayed. For example, tap Help and then the ISO button, and the K2000's 2.7-inch LCD displays, "Access the ISO sensitivity settings and auto ISO range. Higher ISO settings allow faster shutter speeds but may add image noise." Once you've outgrown the button, you can reprogram it as a shortcut to one of four other functions: Custom Preview, Digital Preview, Digital Filter, or RAW image format.

The K2000 does not let you use its LCD as a viewfinder, as most entry-level D-SLRs do. The exclusion of this so-called "Live View" feature is not a huge ding, as you'll frame most of your shots through the viewfinder, but it's always a nice bonus. Live View is convenient for photographers more familiar with LCDs from compact point-and-shooters, but it also comes in handy when you aren't able to look through the viewfinder (as when you're holding the camera above your head).

In the lab I use Imatest to objectively rate the image quality of photos produced by point-and-shooters, D-SLRs, and even cell-phone cameras. In terms of sharpness, the K2000 performed quite well. At its sharpest f-stop, the K2000 averaged 1,776 lines per picture height throughout the image at ISO 100. This rivaled the 1,700 averaged by the Panasonic G1 and the 1,710 averaged by the Nikon D90 (at ISO 200; the D90 doesn't offer ISO 100). The Canon EOS Rebel XSi, though, shut them all down, averaging 2,013 lines.

The K2000 did a good job of retaining sharpness at higher ISO sensitivities. You're safe to expect a crisp picture from ISO 100 to 400: Sharpness at these ISOs averaged between 1,700 and 1,800 lines per picture height. We obtained similar results at ISO 800, but with higher noise levels. Sharpness dropped to the 1,500s at ISO 1600 (which is on a par with that of the Rebel XSi) and to the 1,200s at ISO 3200—but there was also a lot of noise. The K2000, though, smokes the Panasonic G1, which has about 32 percent more noise than the K2000 at ISO 1600 and almost double the noise at ISO 3200. The Rebel XSi shows the least noise overall: about 28 percent less than the K2000 at ISO 800 and about 15 percent less than the K2000 at ISO 1600. Since the Rebel XSi has less noise at those ISO sensitivities, it will produce less grainy shots when shooting in low light without a flash (which typically requires you to increase your ISO sensitivity).

Testing the camera outdoors in Manhattan, I found that the K2000's shots came out beautifully. Photos of my sister and her boyfriend near Grand Central Terminal all had vivid colors and looked sharp. When shooting skylines, however, I noticed that a few of the shots captured the sky as white instead of blue. This is a common issue; I solved it by flipping the white balance to the Outdoors setting.

The K2000 also worked well indoors. In order to capture the inside of Grand Central, I had to increase the ISO sensitivity to 800 and 1600. ISO 800 looked good and was just at the threshold of reasonable noise, but the lack of light made it difficult to get the fast shutter speeds needed for very sharp pictures. When I kicked up the ISO sensitivity to 1600, images were just a bit too noisy. According to Imatest, the K2000's noise levels at ISO 800 are roughly equivalent to the Canon Rebel XSi's noise levels at 1,600, so the Canon would probably have fared better in Grand Central.

The K2000 may be an entry-level D-SLR, but for the most part it doesn't compromise on speed. I was able to turn it on and pull off a shot in a blazing-fast average of 0.58 second. Using Shooting-Digital.com's shutter lag test with pre-focus enabled, the K2000 averaged a practically unnoticeable 0.1 second of shutter lag. Without pre-focus, the K2000D hit closer to 0.2 second—still extremely fast. The K2000 can snap off 3.5 frames per second in continuous shooting, but that can slow down under stress: The camera averaged 0.43 second between shots when I was manually snapping as fast as I could, but after a few seconds it intermittently slowed to a full second.

Pentax bundles the K2000 with a large flash, the AF200FG, which attaches to the camera's topside hot-shoe accessory port. Sold separately, the flash runs $149.95 (direct), but doesn't add much to the K2000 bundle. Although it's stronger than the pop-up flash that's built into the camera, it doesn't swivel like the more expensive AF540FGZ ($335.95 direct). Swiveling allows you to pull off a flash technique called "bounce flash," to create more evenly lit photos without blown-out spots on faces or red eyes.

Similar to the higher-end Olympus E-30 the K2000 has onboard effects Pentax calls filters, which include Retro, Color Extract, Soft Focus, and a few others. Some effects can be applied only after the photo is shot; others can be applied before and after. For the most part, the end results are pretty terrific. My favorite of the bunch is Illustration, which lets you convert pictures into its versions of pastel and watercolor paintings. (Check out the slideshow for some sample shots.)

The Pentax K2000 is a solid choice if you're looking for basics like speed and sharp images in good light, and its Help button can be a valuable guide for those new to D-SLR photography. For a little more money, the $800 (list) Canon EOS Rebel XSi offers less noise at higher ISOs—helping it produce better shots in more situations—and extras like Live View. But this Pentax is still a quality product at a "recession special" price.
