I actually shot with Olympus OM-2 cameras when I started my professional career in the 1980s. Had used them since I was a teenager, and I felt utterly comfortable with them. They couldn't handle the hard use I was giving them however--I always 4 bodies at at the ready, and one or two were always in the repair shop. Ended up in the Canon fold. So wish I had kept all that glass.

I have absolutely no interest in camera comparisons or gear reviews. I'm maybe philosophically interested in equipment only in terms of what effect the form factor has on one's relationship with the act of capture. But pixel peeping--utterly irrelevant to anything. Every camera is pretty much amazing now. The limitations of any equipment is what drives a creative process anyway. I can get good photos with my phone even, despite and because it's a horrible way to interact and actually see what's happening (bright sun say, or composing at arms length). I learn something from having to work around all that. But I'd rather shoot with my deeply familiar Canon 5D iii, with a real time and real life view, through a viewfinder, not some weird electronic interpretation of it, and where I have total control of the composition. It's a camera getting long in the tooth, but so what?
