I don't think they over-hyped it at all. It is a great stills camera and a superb video rig. What does it not do, shoot an hour of 8k?
Shamelessly recycling another post... over a 6 months worth of announcements which was the main issue. I contend that admitting there would be reasonable time limits eg 10 minutes for firmware 1.0 would have meant that the reviewers would have tempered their unrealistic expectations.
Internet: Canon could never put 8K full frame in to a mirrorless camera. They don't have the technical capabilities to do that. The last time they innovated was when 5d mkii was born.
Canon: Our next 5 series will have 8K and demonstrate what we are capable of.
Internet: (spits coffee on screen) Yeah right. Maybe 8K timelapse mode
Canon: No, 8K video
Internet: Er no, 8K like 15 second movie burst mode then, because you know overheating would happen in such a small body. Do Canon engineers not know anything about physics? That's why refrigerators exist....
Canon: No full 8K video
Internet: Yeah right.... hahaha. It's not possible. So no AF or IBIS then. You won't be able to use the full technologies of the camera/
Canon: No. 8K Full frame, AF and IBIS enabled.
Internet: It's not possible, because you know.... overheating is a thing with technology in such a small package. If it was possible then Sony would have done it.
Canon: Hold our beer.....
Internet: I demand a full unconditional apology from Canon. I demand immediately that they give us unlimited 8K full frame video for $4.99 and stop hiding behind this "overheating" scenario to protect their other cameras. I’ve never felt so personally insulted by a camera company as I have by Canon. To me honest behaviour is very important. I recognize that the only person that is perfect is me and people make mistakes. The important thing is to admit that and not to sell us totally unusable technology like this…
