Hi, I have recently bought an EM5-II with 12-40mm f2.8 as an upgrade from my EM10 and have what I think is pretty marked shutter shock issues, which occurs EVERY time from 1/80 to 1/160 and probably wider. Using antishock mode (AS) cures this completely, and I've been in two minds as to whether to send the camera back as I believe I have a particularly bad example, or to just use AS mode permanently and forget about it. I decided today to go for the latter and just use the AS mode, but I've since stumbled into further issues. When I shoot landscapes I use 3 shot exposure bracketing with continuous shooting/drive, and when I do this with the EM5-II the first and third frames are blurred from shutter shot. This happens every time even using AS continuous, and with or without IBIS. I have tried it using normal shutter/AF button (so it focusses between shots) and using the FN1 button as back button AF so the focus is locked and does not change between shots. Just to reiterate I can replicate this every time. I set ISO to 200 to rule out noise, but to be honest the blur is not like that from noise or being out of focus anyway, it's like ghosting. What's even stranger is that if I use AS continuous in normal shooting (ie without bracketing) then I don't get shutter shock. This kind of suggests to me that bracketing somehow interferes with AS mode? So the camera can't be used for what I need it to so it has to go back, but what I need to find out is whether I've got a bad example, or whether most/all EM5-II's are the same. If mine's a one off then I'm happy to exchange it, but if not then I'm going to have to get a refund and either stick with my EM10, or consider changing systems (as one of the main reasons for getting the EM5-II was weather sealing). So what I'd like to know is whether other EM5-II users are experiencing similar problems, and if so how many? The worst effected shutter speeds for me are 1/100 and 1/125. I have the same issue with both the 12-40mm f2.8 and Panasonic 12-32mm pancake. Here's a couple of examples of the same image taking with and without AS. These are 100% crops, but I saw strangely soft images when viewing normally which is what made me view at 1:1. Oh and case someone asks, yes this happens whether on a tripod or not, with or without IBIS. Any help will be greatly appreciated.
