The EOS 3 is great fun, I haave one along witb an EOS 5. Film really challenges as you are limited to 24/36 frames and £s to get to see them. It's a grounding mechanism and you really have to think about your shots. It has been a while since I did my own D&P but getting tempted to dig out my stored kit.
I need to downsize my Pentax M kit whilst getting my 645 out and working!
I have shot about 5 rolls whilst on my recent trip and the discipline of a fixed number of frames as opposed to a multi sqillion capacity memory card is very real!
Enjoy!
