Just had an Alpha 200 for 2 weeks, having used Minolta 35mm cameras before. Have to say I love the Sony, and for around 280 quid its a sweet bit of kit. . I do have a few minor improvements I would make if I could.
Liveview would be nice for the odd occasion when the viewfinder is inaccessible, but I find in 99% of situations I love the information display, and as an old school photographer I instinctively go for the viewfinder anyway.
As I enjoy HDR, I would have liked the auto bracketing to be wider than +/-0.7 and would like to take more than 3 exposures.
The real niggle for me is that the software is not compatible with 64bit vista, and that there are no 64bit codecs available so you can view your camera raw files in windows. Given that 64bit processors are practically the norm now, this is a major oversight by Sony, and I hope their software department are working on it as we speak.
These are only minor points, and have not put me off the A200 at all, as the positives really drown out the niggles.
The camera is really comfortable in the hand, and all the controls are ergonomically placed. The camera is full of advanced features and they all work well. I love the Sony infolithium batteries, nothing worse for me than a camera that takes AA batteries.
I know you didnt ask for a camera review, but thought I would add my first impressions of the camera. I wouldnt hesitate in buying the same camera again.
