Title: Full res silent pics on 5D2 or 6D with 360° shutter (@.5sec interval), possible?
Post by: Joachim Buambeki on April 11, 2016, 09:09:03 PM
Hey guys,

I am asking myself if I can get 360° (or very close) shutter with full res silent pictures and intervals of around .5sec. to capture true continuous motion.
Is there a significant processing (down) time between the shots or is it possible to achieve this? Given I use a card fast enough, data rates will not be the issue, right?
Rolling shutter should not be an issue with such shutter speeds, or am I mistaken?

I would like to go full frame and have my eyes set to a 5D2 (preferably) or 6D but I am open to other suggestions in a similar price range as well if said cameras arent't suitable for this task.
Why would you pick the 6D over the 5D2 and vice versa? I assume the 5D2 has faster write speeds with its CF cards despite the 6D having the better sensor overall.


Looking forward to your replies and suggestions! TIA :)

Cheers
JB

Rolling shutter is a major issue. It's about 0.25 seconds. It also causes a strong gradient.

At 2 FPS, write speed will likely be an issue too. A full size raw frame is around 40MB. Neither camera you mention is capable of 80MB/s.

Thanks for your reply and the insight. I could live with the gradient (if it acts like a real graduated ND and doesn't degrade the image in any other form -I use ND grads all the time anyway) but a Rolling Shutter of 1/4 sec is unacceptable.
According to this post (http://), the 5D3 is only twice as fast and all the other are equally bad or even worse. This pretty much makes my idea unfeasible I think... :'(

I might have to bite the bullet and save up for an URSA Mini or something in that league.

Does someone have any other ideas regarding this?
