This is a very interesting thread for me, as I am just getting back into photography after a break of 20 years. I started photography with the all manual Praktica MTL3, because it was cheap, and got hooked. For some reason the importance of avoiding camera shake really made an impression on me and Canon's use of shutter priority auto on the AE-1 led me to buy that camera. When the A-1 came out shortly after I thought it was amazing, and had to have one, given I needed two cameras to do colour and b&w. When the T-90 came out it seemed space age, and I got one for the tremendous metering flexibility. Then shortly after Canon started to shift to auto-focus development, and FD lenses became obsolete. I gave up photography shortly after. When I wanted to use a camera again a few years later the T-90 shutter had seized. I got it fixed. It seized again... Now, I've been considering the Nikon D5100 and the Canon 600D. One brother-in-law uses a D700, the other a 5Dmk2. Both are supporting their brands! I really wanted to get the 5100 as I felt I'd been sold down the river by Canon, as my mass of FD stuff, which I still have, was no longer usable with EOS bodies. My Nikon brother-in-law, kept telling me how Nikon hadn't changed their lens mount etc. But the D5100 video seemed poor compared to the 600D. I don't anticipate using it much but my wife does. The handling for stills just didn't suit me - not enough direct access to what seem important parameters, if I understand digital ways of working well enough. I bought the 600D body yesterday to get the current cashback. Lens choices next! Then full-frame enticement probably as everywhere I go now I'm seeing potential photos..... Canon for APS-C it would seem, but I'm still keeping an open mind should I decide at some point to go for full frame, as the EF-S lenses needed for best match with the cropped format wouldn't be any use. At least Nikon is no different in that respect. I can envisage my son taking the Canon stuff with him when he leaves home and me starting from scratch again! Will I go for Canon for a third time?
