Re: What happens when you press the shutter
2010/8/19 Adam Maas a...@mawz.ca: I suspect it comes down to 8+ fps cameras need better damping and get it. Note the 5D, like the K10D, is a 3fps camera in the high-end consumer/semi-pro market. The F5 and D3 are much higher-end cameras at higher prices and with far higher framerates. Oh definitely but one would think that mirror wobble or lack of damping thereof introduces vibration into the system. Question is, does this have any impact on second and subsequent shot SR in serial exposures (I won't talk of high speed there, my old FD Canons all did 4.5 or 5 fps resp.)?

Re: What happens when you press the shutter
In all the comparisons I watched (3) the mirror up bounce was pretty well controlled, with a fairly long pause prior to the shutter activation. It's the return that is much less controlled on most of them. Then another really long pause before the cycle begins again. And as was said, to get a higher frame rate, it cost a lot more to control that mirror (and shutter flutter). More than I am willing to pay.

Re: What happens when you press the shutter
Interesting comparison if you look at the similar clips of a F5 or D3 - in the K10D the mirror wobbles all over the place until it finally settles whereas the Nikons stop and dampen it very effectively. Lots of time to gained there...

Re: What happens when you press the shutter
The Canon 5D mirror bounces around as much as the K10D one does; the Nikons do seem better at damping. Very interesting to watch.
