The Canon T90 is an anomaly. On the one hand it represents the first modern electronic SLR. Gone are the manual dials for shutter, ISO, and various other settings. Instead we have the multi-function dials we find on modern cameras and LCD displays for various settings/options. Oddly though it's still a manual focus SLR. The mix works though and because of the odd timing between it and the Canon EOS line these ended up not being hugely popular. You can find them quite easily and frankly they might be a better option than the more popular Canon AE-1. Mine was on sale from KEH at a pretty good price.

My Copy's Performance
This camera is awesome. It's so close to modern cameras that transitioning back and forth between this and my Sony A7RII doesn't require much of a mental shift. When you mount the lighter weight Canon (n)FD lenses the weight is nice but when you mount the breech-lock metal lenses it becomes very heavy. Overall I just can't really complain - it's a fun camera to use and I expect that it's going to be a mainstay for me for a very long time.
