I've been using Sony mirrorless cameras for the past couple of years and have never liked them - always thought I would jump back to a dslr. Well last week I had to use the latest Canon 5Div (i believe) on an assignment. NOPE never again! I couldn't believe how it made the Sony cameras seem so advanced (actually how stepping back in tech history the dslr was). Although honestly a big part of the problem is Canon has just been crippling their lineup so much not to make an overall good camera (spec wise).
What is dead is limited software cameras. Cameras that are obviously intentionally crippled. I spent many years self cocking the shutter and putting one sheet of film in at a time - those days are gone. I am not paying $$$$ for a camera that doesn't have a healthy spec sheet. The camera doesn't make the picture I do I don't need a camera company that thinks it can force me to buy (and carry) many different options.
