Re: Shutter Shock - not a problem for the M6

It's also why the EOS R5 tends to exhibit it more than the R6 due to the difference in sensor crowding.

With those bodies it's never an issue as you have the option to use EFSC. When you need EFSC you don't need full mechanical and vice versa, so with either the R6 or the R5 you'll never have a problem.

On my R5 I have one C-mode for Av + 1/250th as a minimum shutter speed (combined with Auto ISO) + full mechanical shutter mode for when I want to shoot at large apertures, eventually at shutterspeeds of 1/1000th or faster. 1/250th is fast enough to get rid of shutter shock. If I need slower I change to normal Av as all non-C modes have a minimum shutter speed of 1/125th + EFSC as a default.

I have another C-mode for M + auto ISO without a minimum shutter speed with EFSC for when I need slower than 1/125th, or faster than 1/250th. Sometimes I use normal Av + ISO fixed at 400.

With just 2 C-modes I have no camera motion blur, shutter shock or cut of bokeh with a almost no baby sitting of settings. You can do exactly the same with the R6.

With the M6II you can't do that, which is strange, as this camera won't suffer that much from cut off bokeh anyway.

The shutter looks like this.

Thanks.  I hadn't yet been able to find a picture.  The shutter blade looks exactly correct and the physical size and layout is quite logical for the M6II body.  The only thing weird in those images is that one blade is closed.  The resting position for the M6II is always with both blades open, but it probably isn't hard to physically change the blade position for a photo and perhaps they wanted to show the blade for confirmation that the blades are included with the assembly.  I believe this is the shutter assembly for an M6II and I found that picture quite informative.
