The internet is overflowing with opinions, everyone gets to give one, and it is up to the reader to decide whether an individual opinion is worth listening to.
True. And I agree that the UI and signal to noise ratio at DPR are a royal pain. I was researching an AF issue for a student when I found this thread...
Nevertheless, Canon has had exposure & AF problems in the past that they've been VERY slow to respond to officially. If at all. In 20 years as a commercial photographer and 13 as a Canon user – the number of times I've first learned of known technical problems from the equipment manufacturer is exactly zero. I'll take my info where I can get it. Then confirm it elsewhere.
This looks like a great forum and a good resource. I look forward to reading more.
