Find this post little condescending May be i am in a bad mood.
I have shot with a 10 mp point and shoot for years. My technically best images(sharp, blah blah) shot with the best gear are boring compared to what i shot with a Panasonic LX3. The best pictures i have shot are not technically perfect.
This is creative art. All a technically perfect shot gives you is the capability to blow it up to a bigger size. But that will not convert a boring picture into a great picture.
If i am a scientist, shutter vibration is an important issue to me. If i am a photographer, professional or not, these things are academic at best.
Sometimes, these things become an end in themselves. Which they are not.

I must say after a week of testing the A7R with my Nikon optics and the Zeiss 35 f2.8 I haven\'t found one image that I would\'ve said was unacceptable because of shutter vibration. I have the camera mounted on a steel Gitzo tripod with a 504 video head. When I was testing the 70-200 VR 2 with meta-bones adapter most of the shutter speeds were under a 30th and up to three seconds for the full range of f-stops, here again I saw no vibration but did see some diffraction at f22. I just finished a series with a 50mm 1.8G that showed no vibration again, overall the quality of this lens on me A7r is much better than the $200 it cost\'s.
dennishh, you don\'t have to worry, if you see \"some diffraction at f/22\" but not on f/8, f/11 or f/16 you most likely won\'t see any vibration...ever...also you would be ok with 5Mpix camera as well. At least back in 2002 when I had 3.3Mpix 1.6crop Canon D30 the f/11 diffraction was visible, and f/16 it was very clearly visible.
If shooting from rigid base (camera bolted to concrete or sturdy tripod with good head, doesn\'t matter) in landscape orientation the amount of shutter \"shock\" induced blur is only causing micro contrast loss with 55mm lens, and at 35mm there is ~50% of what can be seen with 55mm.

There are so many other factors that come into producing image movement that makes this statement of shutter vibration very difficult to verify.
Well it depends what you are doing. If you are tripod mounted using remote shutter or 10s delay either indoors or outdoors without wind there really isn\'t anything else than shutter induced movement (unless you get movement due to ground shaking). If there is movement just camera sitting on top of tripod then it might be time to get new tripod...

I\'ve used my A7R for two or three professional jobs since I\'ve purchased it along with my D 800e so maybe my requirements as a professional are less stringent than \"scientific photo equipment testing experts\". I will keep looking to see if I can reproduce there findings.
There are many kind of professionals. For example photographer shooting for newspaper one\'s requirements as professional regarding small detail sharpness are low or non-existing. I know professional photographers who have never touched tripod and/or always shoot in \"green mode\" with kit lens on cheapest crop body. For me that somebody is professional doesn\'t mean they are good at it, or are good in all areas of their industry - it just means they are doing it to earn money without any indication to anything else.
