Food for thought...doesn't mention 'lossy' raw files though.
Theres a few cool things about mirrorless. But he fails to mention the things dslrs are best at. Tbh it looks like he got paid for his thoughts.
He has some good points, though he's forgetting the things that make a pro-camera what it is: a lack of fiddly gimmicks and designed in robustness. The thing is that some of what has been tried out for the consumer would also benefit the pro, and I'd guess that Sony have less need to be conservative than canikon.
Personally I really like my Sony SLT.
