Engadget tested the A6600 and the conclusion isn’t that favorable:
It’s bizarre that Sony didn’t update the sensor over the last model, considering that it’s the world’s leader in sensor technology. The bad rolling shutter was the biggest weakness of the original A6500, and it’s now back to haunt the A6600. In 2019, it has to compete against the X-T3, Z 50, Canon’s M6 II and Panasonic’s GH5, none of which have rolling shutter that’s nearly as noticeable. I also wish it had two faster card slots and more advanced 4K options.
If you’re looking to spend $1,400, I’d get the X-T3 instead, which is a better all around camera. If it’s resolution you need, take a look at Canon’s M6 Mark II which is cheaper ($1,050 with the EVF) and can also shoot faster. If you’re okay with a smaller Micro Four Thirds sensor, Panasonic’s $1,500 GH5 is still the best video-centric mirrorless camera out there, especially with recent AF firmware updates.
I agree with Steve Dent, the A6600 is surely a highly capable camera but at the moment the Fuji X-T3 has the edge. I do hope Sony will offer a more “serious” contender with improved body design.
