My primary camera is a Canon 5D3. I decided recently that I wanted a
smaller camera for short trips, carrying around casually. I finally
decided on a Canon M3. I looked around in here for some discussion
about it, but don't see anything. So far, I don't have any dedicated
M lenses. I do have an EF adapter, and have been using my Canon F.14
50 mm EF, and a Rokinon 8mm wide angle. The wide angle is fun. Size
wise, it reminds me of my old Pentax Auto 110, 110-film SLR. Couple
of things I notice though, is that if you have big hands, this thing
is almost too small. Very easy to hit controls when you are just
trying to hold it. The other thing that I've found bothers me is the
electronic view finder. I hate holding a camera at arm's length to
look at the display. So I bought the electronic view finder. If this
is any indication of EVFs, I'm happy to stick with an SLR for serious
phnotography. I can't make out if it's in sharp focus or not. Anybody
else notice these things?

Once things are in focus, I've got no problem with the pictures it
produces.
