Well I've had the D90 for about a month now (Gripped with SB-600) and do you know what - I didn't really need it. There's not one photo I can take with the D90 that I can't with my trusty old D40x. The problem for me is that it has too many toys to play with - I find myself playing with the camera and not using the camera. Taking test shots and marvelling at the better ISO performance, the active D-Lighting, the multiple focus points that consistently mangage to pick out the eyes. Fantastic, but I havent actually produced much, if anything, of photographic value with it. I've posted a couple of photos from it but in all honesty for me these photos were borderline "Do I, Don't I post" cases. I suppose playing with the camera means that I'll know the camera inside out, but I sometimes get the feeling that I'll pass the 100,000 shutter lifetime just taking test shots. Do I regret buying the D90 - hell no. It'll serve me well and I'm immensely happy with, but what I've learned is that I don't always need the latest and greatest, and that I need to get back to photography and stop messing around. So excuse me while I re-read Understanding Exposure, dust off the D40x (I know this camera inside out so I won't be distracted), and get back to making photographs, not test snapshots. By the way, has anybody got any news on the D400?
