I bought a couple of these for our Photo Department. Small, light, powerful. The R10, and adapters, are the beginning of our transition to Mirrorless from a pretty well-established Canon/Nikon DSLR system of bodies and lenses. I have lots of experience with 1, 10D, 60D, 70D and all the Rebels. I first played with the 16mm f2.8; light if nothing else. Tossed on a 24-70 2.8 and an adapter for a shoot with a few students of a political rally. I had few goals and almost no pressure to perform; I was there for support. It gave me a lot of time to sort the machine out. Controls take a bit of time to locate and understand; the focusing system will take some time, but, it's just a camera. Custom White Balance was a snap. I found out that I really don't like the floppy screen; very awkward when trying to hold the camera to get above the crowd, it hits the left wrist. Similar problem when held below as well.
