Say it ain't so, Ken! What is it with mirrorless cameras? They usually have no real focus rings, and certainly no depth-of-field scales so people can calculate optimum apertures; and autofocus can be totally retarded all the way to before the 1980s! Honest, I compared the AF speed and performance of the EOS-M directly to my 1987 35mm Canon EOS 650 and a 1980s EF 50mm f/1.8, and the 26-year-old EOS camera still has much better and faster autofocus.
