Sony fanbois are making lots of noise, and rightly so the new toy in town looks pretty cool, has some neat tricks and takes a mean picture.
I had the opportunity more than once now to play with the a7RII and a6300, very nice, but let's not get carried away here. Both are incremental improvements and really move both lines forward and improve items that probably limited past owners, offered enough to lure some new users too.
I'll claim to be agnostic as I believe the evolution of the high end image capture tool must eventually move from a flapping mirror to a mirrorless, just too many advantages, but sadly all the reasons being trumped still aren't good enough yet for how I shoot. Might be good enough for others to flee the Canikon family and feel joy in the company of these loud fanbois, LOL. A EVF may someday be good enough, but still not there, it is really good enough already for most casual shooting but pressed for the fastest action the focus and tracking still NOT there, close. Sorry I don't drop 10000 bucks to be close, I buy to have what gives me the best possible chance to get the shot, it ain't with mirrorless, LOL.
For some maybe they can see or pretend some advantage and changing systems saves them a few cubic cm and a few hundred grams in their bag, but they are fooling themselves. Just eat a bit less, exercise a bit more and you'll be far better off in Canikon land, trust me don't be stupid early adopter.
Two sides to the story:
