EOS 5D MK II - HD Video

[Puncball]

Hi,

I have read in several reviews that, although not specified by Canon, the shutter in the EOS 5D Mk II is designed (good) for 100,000 operations; i.e. failures of the shutter is not likely to occur until after 100,000 photogaphs have been taken - a life time when taking photographs, normally.

Is there a reason to be concerned if you use the HD Video regularly.

I understand that the HD Video operates at a shutter rate of 30 pps, which equates to 18,000 images/shutter operations, for a 10 minute video.

Am I missing the point, or am I correct in thinking that if I took 6 videos, each of 10 minutes duration, I would exceed the expected life of the shutter (30 pps x 60 seconds x 10 minutes x 6 videos = 108,000)

I'm not sure, but I think the shutter actuations involve the process of flipping the mirror system and so forth. As the HD Video is shot with the mirror system flipped up at the very beginning - I'd just count that as '1' ?

As far as I know, the shutter flips down once to enable live-view so I would
say one shutter flip per video?

I am fairly sure that the shutter will stay open for the entire length of a capture. Thus whether you take a 1 second or 10 minute video the shutter will only open and close once.

It'd be a noisy video camera if that shutter kept going up and down at 30fps! Imagine the soundtrack

The shutter just raises once, then the camera is nothing more than a normal DV camcorder essentially

just the once for video it records at 30 fps to make and moving image but doesnt actuate the shutter or mirror during video capture.

Thanks for all of the replies

The 5D Mark II is rated for 150,000 actuations

Not sure about the answer to the question..I'd imagine it would be 1 actuation per movie shot :shrug:
