ive had my a200 for just over a year now and im pretty pleased with my progress and wish to upgrade.. i was looking at the a550, all i really want is a body with better noise control, id love to be able to go up to 800 or 1000 at times but on my a200 i cant really go above 400, its just a mess. so it looks like the a550 would be good ? the reviews dont look all that good but im not a pro just a mom with a camera and really i jsut want a step up from my a200if its not going to be that much better then i wont do it.
