Not exactly a glowing review...but I think it is a fair assessment. Even from the perspective of someone heavily invested in the Canon system like myself...
Here's what I think...the issue with the camera isn't it's feature set. As the review points out, and as folks who have picked up the camera have alluded to, it's a good, capable camera in its own respects. Rather, it is the price point, and perceived value for money where it seems to be falling a bit short. If they announced it at $1500 or even $1700 I think it would have been received better. But once you hit $2K, people now expect a bit more camera for that kind of money - especially with the Nikon D750 and even Canon's 5D III available for the same amount. It's almost like a brand premium, i.e., you're paying for the Canon name and they wouldn't be the only company to do that, there's nothing inherently wrong with it - they're betting that this target market would be willing to pay more for the Canon name and time will tell whether that is true or not.
