Re: Defective IBIS module...

Thank you for your response and experience with shutter shock and IBIS. Packaging the camera up now.

Unfortunately you have what I believe is a defect in the IBIS mechanism. I have seen this once before. Another example of what I believe was a much more severe version had the entire IBIS mechanism shaking through the viewfinder like it was strapped to a mechanical paint mixer. It's extremely rare. But Canon WILL fix it for you. They may replace the camera completely or they may know the faulty component and swap out out.

The risk of Shutter Shock on the EOS R6 can (but usually does not) occur under 1/160 second and tends to show up in the first shot if a burst is fired. The risk of Shutter Shock occurring with the EOS R5 is with images shot at 1/250 second. Since one of your shots has a defect that occurs at shutter speeds of 1/200 second, we can conclude this is not a typical (normal) example of IBIS related Shutter Shock since that is over 1/160 sec.
.
Shutter Shock is also much more subtle. It's usually only visible at the pixel-level when viewing an image at 100% and appears to be just slightly blurred. It really is rather subtle. These examples are not. I've taken plenty of pictures at less than 1/160sec without issue using mechanical shutter without issue. The R6 ships with EFCS (Electronic First Curtain Shutter) active for this very reason. Electronic Shutter is also an option but both of these shutter methods have limitations of their own (EFCS has a slight effect of Bokeh and Electronic Shutter is not recommended for higher shutter speeds).
.
Send your camera in to Canon and they'll fix the situation for your. I'm sorry you've been inconvenienced. It's probably better to discover this problem before taking an important photograph. Your images are at the extreme range and I believe that this is not related to shutter shock but a fault in the mechanical mechanism for the IBIS module.
