From Dan Chung:


"There is growing evidence that several owners’ production models of the Blackmagic Cinema Camera are experiencing serious issues with infinity focus on certain lenses. Initially, users identified the popular EOS fitTokina 11-16mm f2.8 as a problem lens, with an inability to focus anywhere near infinity when used with the BMCC. Now other users are reporting that other lenses are affected too."

Thanks Bruno but I have edited your post. Main topics cannot consist of just an URL leading people away from the forum to find out what the topic is about. You have to put more effort into the post and put the info in, along with your opinion of it if you have one.

 

Dan's site was the first to run this article so I have changed the URL to point at him. Only fair the source gets the credit.

Fair enough, was in a bit of a hurry but thought I'd share the news.

 

Have you noticed similar problems btw? Hope this doesn't slow them down again.

I've mostly shot with adapted lenses on the Blackmagic, so not so much EF stuff and hardly used the 11-16mm.

 

Though 90% of this video is Samyang 35mm, I used the Tokina 11-16mm it for a few shots here and infinity was not exactly very sharp.

I also noticed that there's a bit of flex in the mount of the camera but not sure if I should be worried about it yet.

 

The Tokina has a shim which you can remove to fix the infinity issues https://dl.dropbox.com/u/3464747/Tokina_Shim_Removal_v2.pdf

 

I need to do more tests with my camera before truly deciding if it has a fault or not. All I have at the moment is a strong suspicion.

 

Why didn't the beta testers catch this?

Maybe they were too busy trying to get shallow DOF shots?
Maybe they were told they didn't have the latest build of the camera and expected some glitches. Or maybe there were not enough of them!

Or the last maybe... Maybe it's not such a big issue and doesn't affect that many cameras... That's more of a 'hopefully'.
