its very easy to see if you run the right test looking for it.. i saw it before i knew what it was.. now i know exactly what it is.. exactly how to reproduce it and exactly how to avoid it..

everyone gets the odd blurry or soft shot.. it gets blamed on missed focus user induced blur or just one those things or just a poor lens.. more often than not its shutter shock or camera induced motion blur..

take one GX7 body.. one 14-140 lens.. put the two together and set the shutter speed at 1/160th of second.. pick a focal length you can be sure of holding the camera steady at.. take a few shots of something with detail in it..

then do the same thing using the electronic shutter.. compare the difference..

if you cant see it get some new glasses or a new monitor..

i see it and i can repeat it every single time.. and with more than one body lens combination..

Dear Trog, I don't have GX7 for that test. However, since early report on SS, it would just cause a soft image but not a blur one. Because the very slight vibration generated by shutter movement would never be hard enough to shake camera as normal handshake would do.

I still remember that back to the old days, a lot of tests and argument had been put forward to prove its existence, or otherwise. A lot of suggestion had also be given trying to naturalize SS like adding weight etc to damper the effect. But as SS was caused by shutter movement (within a particular set of shutter speed, on certain model and certain lenses), it was strongly believed that SS would not be avoidable even when shooting on tripod.

So, if you could test yours by shooting on a tripod, and could get similar sharp images as using e-shutter, most likely other factors might cause soft images other than SS. If not, it would be a definite proof to have SS on your particular set of camera and lens.

Looking forward for your judgement as I'll soon upgrade to GX7.
