UP CLOSE AND PERSONAL

       Olympus may be leading in the superzoom wars with its 26x optical zoom SP-590UZ, but it takes a lot more than a long lens to make a decent longzoom camera. We're talking the same things it takes to make a good digital camera, like speedy performance, a competitive, useful feature set, and good picture quality.
       DESIGN AND FEATURES
       With the large handgrip, the SP-590UZ looks like a dSLR. The design is typical a big, solid body with a plastic chassis and a large, rubberised grip accommodating the four AA batteries that power the camera.For a nice touch, the bottom of the shooter extends out beneath the lens to provide a more stable platform when mounted on a tripod. Unfortunately, the camera takes two equally inconvenient forms of media:Olympus/Fujifilm's proprietary xD-Picture Cards or microSD media which fits into an xD card adapter.
       Overall, the SP-590UZ is fairly straightforward to learn and operate if you've used a digital camera in the past couple of years. In addition to all the usual suspects on the mode dial, the snapper includes Beauty mode which blurs skin slightly.Even if it works extremely well, it's way too slow - approximately 20 seconds between shots - and the result is a two megapixel image.
       There is also MyMode which holds up to four groups of custom settings, which includes the focal length setting at the time you saved them. An OK/Func button pulls up frequently needed shooting settings, which include drive mode, white balance, ISO sensitivity, metering, image size and compression.
       Besides the standard continuous shooting, there are higher-speed drive modes:6fps and 10fps. However, they operate at reduced image sizes of five and three megapixels, respectively. This includes a precapture high-speed mode that shoots 10 three-megapixel frames at 10fps from focus lock until you snap the photo.
       Like most megazooms, the SP-590UZ produces its sharpest shots in Super Macro mode, and the results are pretty sharp.
       There are dedicated buttons for exposure compensation, flash, macro mode and selftimer, as well as a toggling Shadow Adjustment and a custom button to which you can assign a variety of capabilities,including image stabiliser, focus/AE lock,and focus mode. You can bracket the exposure up to five shots - most cameras limit you to three - in +/-1/3,2/3 or full stop intervals. While the SP-590UZ supports optical zoom when recording video, at best the camera does 30fps VGA saved as Motion JPEG-compressed AVI files. You can't zoom and record sound at the same time. That's certainly one way to defeat noise created by the lens mechanism moving.
       PERFORMANCE
       With the exception of overly long shot lag in dim light, the SP-590UZ delivers pretty typical performance for a megazoom. It powers on and shoots in 1.6 seconds, which is actually pretty fast in this class. In good light it matches the focus-and-shoot speed of the best of its class -0.6 second - but in dim light it struggles, resulting in an overly slow 1.4 second delay. Its two second shot-to-shot time matches the rest of the crowd, and enabling flash bumps that to a pretty typical 2.5 seconds. While its continuous shooting rate of 1.2fps sits close to the bottom of its class, frame rate is almost immaterial with an electronic viewfinder (EVF) camera since your real constraint for burst usability is the blackout interval of the viewfinder, which is almost universally bad.
       As is typical with EVFs, the colours look completely different than on the LCD, but it refreshes quickly, even in low light, and it is relatively well-magnified. The screen itself is too reflective to work well in direct sunlight, but you can set everything to display only on the EVF. Olympus' optical image stabilizer works well out to the end of the zoom range.
       IMAGE QUALITY
       We debated on the rating of the SP-590UZ's photo quality. It's not bad, and if you're not picky, you'll probably be very happy with the photos. However, even at low sensitivities (ISO 64 and ISO 100) our photos displayed visible noise, a lack of sharpness and had that painterly artifact quality usually associated with higher ISO images, which makes prints look soft. The automatic white balance yields cool results in all lights (which, ironically, results in pretty good rendering under i-candescent lighting). But metering and exposures are good, and there's practically no fringing.Colours are vibrant and pleasing,but not very accurate. The loresolution video capture looks pretty good and perfectly sufficient for YouTube, but it's hard to get around the audio/zoom trade-off.
       Ultimately, the Olympus SP-590UZ ranks as a functional but not particularly notable superzoom. While none of the current models have a 26x optical zoom, as with many superzooms,the EVF makes it impractical to shoot the things most people want the long lens for - childrens'sports, for example. So you may as well go with an alternative.
