The question of 2008 seems to be, "Do you really need 12 megapixels in a compact camera?" This idea surfaced again with the Sony Cyber-shot DSC-W200. Over at PhotographyBLOG, Mark Goldstein has published a Sony Cyber-shot DSC-W200 review. Here's a few bits of what Mark has to say:
"At first glance the Sony Cyber-shot DSC-W200 looks like a fairly run-of-the mill compact camera, with an understated, compact silver body, 3x zoom lens (35-105mm) and 2.5 inch LCD screen. Look a little closer though, and you'll find that there are some more impressive stand-out features. Most obvious is the headline-grabbing 12 megapixel resolution, now the standard for any self-respecting top-of-the range compact like the W200. Next up is true optical image stabilisation via Sony's Super SteadyShot technology, which combined with the extensive ISO range of 100-3200 promises to make blurry photos a thing of the past. The Sony W200 also offers a true Manual shooting mode which allows you to set both the shutter speed and aperture, and there's also an optical viewfinder for ease-of-use in bright sunlight. The Sony Cyber-shot DSC-W200 is therefore a mix of humdrum and rather more exciting features, on paper at least."
Sounds interesting, but in the conclusion he adds...
"The 12 megapixel sensor may give you bags of resolution to play with, but it comes at the cost of noisy images at the slow speed of ISO 200 and quite a lot of unwanted chromatic aberrations."
Hmmmm.... I guess the 12 megapixel debate discussion continues. If you're interested, you might want to read Mark's full review.
