I'm still shopping for a DSLR and although I really like the D90, I just read dpreview.com's review of the new Sony Alpha A550 and was surprised at how well it was received. What's particularly attractive to me is it has in-body image stabilization, while the Nikon doesn't. Not sure how much weight I should put on that one feature, but I do plan to buy one or more prime lenses that have no built-in IS, so I'm concerned about being able to get good shots sans tripod. The Pentax K-x is another camera on my radar, again because it has in-body IS. The downside with the K-x is it uses AA batteries and there's some issue around AF points in the viewfinder, can't remember. You can check out the review here: Review: 1. Introduction: Digital Photography Review Here are the pros and cons, from the conclusion portion of that review: Conclusion - Pros Capable of excellent results (especially in raw) Good JPEG dynamic range Far better high ISO performance than most other recent Alpha models Fast and responsive operation - and up to 7 fps burst shooting Excellent screen and improved viewfinder (though it still works better in Live View) Class-leading live-view autofocus system and new high quality main sensor live view option Improved user interface (though still no interactive control panel screen) Effective in-camera image stabilization Clever automatic HDR feature and DRO shadow adjustment Improved handling and external controls over A3XX models Probably the easiest 'high end' camera for the compact camera upgrader to use Excellent battery life Wireless flash capability built-in and optional remote control Well-featured and usable software included Decent 18-55mm kit lens Conclusion - Cons JPEG output doesn't really do the sensor justice - shoot raw for the best results Default output over processed: too much contrast, saturation (reds in particular often end up overdone) and noise reduction for our taste Metering not reliable enough, easily fooled by unusual subjects and large skies (often over exposing) More auto white balance errors than we'd expect at this level Not enough control of noise reduction for JPEGs (high or really high) No Program Shift or Depth of Field Preview Very Limited customization options compared to competitors Some shadow noise visible even at base ISO in certain shooting conditions Despite improvements the viewfinder still not that great - hard to get your eye near enough Button placement is less than optimal In today's market, at this price, lack of video has to be mentioned One thing that was mentioned is there is no "mirror lock up" function. Since I've never owned a DSLR I really don't know what that does, let alone its value. Anyway, I'm hoping that those with more experience with DSLRs in general and Sony products in particular will offer some advice and tips. Thanks in advance.
