Well Stan, that sure makes it sound like a deal breaker if that was your primary need for the camera.
The flash sync speed is not the deal breaker for me (there are others) but for those of us with a wide range of uses there is a desire that a $2k camera meet those needs at least as well as our older and less expensive camera. Certainly other needs will be better met....but why go backwards?
And again, I'm am unsure how the lower sync speed will affect my macro photography where the sync speed issue has little to do with fill or GN but everything to do with camera movement. The issue is sharpness, not GN.
