Shutter shock test

I tested previously for shutter shock in my M11 and could not detect anything when shooting wide to normal focal lengths, handheld.

In a second test, I used the APO-TELYT-R 180/3.4 on M11 and M10-R, tripod mounted, ISO800, 1/30sec, and compared the results at 200% (LrC). Finally, I resized M11's files to M10-R's resolution and turned all noise reduction and sharpening off.
The results show a slight loss of sharpness with the mechanical shutter, both M10-R, and M11. The best result is with the electronic shutter. 

The order of images: whole frame, M10-R, M11 mechanical, M11 electronic.

Silver or black M11? Curious if that changes results at all for mechanical shutter. Brass top Probably has zero affect.

Silver M11. I would not think that the slight weight difference plays a role.

Thanks for this test result.  Can we assume live view was off on the M10 images?  

1/15sec to 1/4 sec tests?  From my testing  of tripod and camera combinations these were most susceptible to shutter shock along with 1/30 sec you have tested.

Very good question. I made a mistake and shot M10-R in LV instead of RF mode. 

Reshot the test, and the RF mode in M10-R is practically the same as with LV. M11's electronic shutter is still the sharpest.

This is also what I found with the M10-R and P, live view didn't affect sharpness.  I never tested the M10, the M240 required Live View be turned off to avoid shutter shock, it was very pronounced.

Thanks for the tests and input fellas.

Quite an eye-opener, and disconcerting.

I would not worry.
I saw no issues shooting handheld at 50mm or wider. With longer focal length, handheld shooting requires faster shutter speeds, and typically shutter shock does not appear at higher shutter speeds.
When shooting longer focal lengths on a tripod (slower shutter speeds), I would switch to an electronic shutter if possible.

Slow shutter speeds = 1/30 and below? 

I currently have my auto ISO set at 1/250 as the minimum shutter speed to avoid any unwanted shake or loss of sharpness with this huge sensor. I only shoot 35mm and 50mm by the way.

AFAIK, shutter shock typically manifests itself only at < 1/250 sec, if at all. With M11, I have not seen a negative effect of shutter vibration at 50mm or wider. I do not want to waste light and shoot at shutter speed limit 1/(2f)s instead of a fixed 1/250. As they say, YMMV.
