On the silent shutter "need", not only does the shutter on IBIS cameras cause havoc with moving the sensor (and does the M5 not have IBIS), it also creates noisier images and less DR due to an increase in read noise.

 

Sony drops RAW from 14 to 12 bits when using silent shutter mode (or 13 bits to 12 bits).

 

And then there is the rolling shutter issue. It seems the wish for silent shutter is more a specs list reading thing?

 

This is only true for certain brands. For instance, the full electronic shutter on Olympus and Fuji does not decrease DR unlike on Panasonic Cameras: http://m43photo.blogspot.ch/2015/04/e-m5...tters.html

 

The rolling shutter artifact is a non issue, unless the only thing one shoots is fast action. I pretty much only shoot  portraits wide-open at f1.4 or f1.2 with my Fuji X-T1. On sunny days, the shutter speed easily reaches the 1/10'000 to 1/30'000 range when I shoot my never-still daughter. Despite this, I almost never encounter any rolling shutter artifacts.
