The gist of the shutter shock myth is that *IF* you go look for it, you will find it. If you don't go look for it, you will probably never encounter it. If you encounter it, all you have to do is choose a different shutter speed, which is very well doable with the high-iso capability of the A7r. I think that was what the op already said in his words.

You don't need to go looking for it to see it, as it is viewable at a lot less than 100%. Some people can't see it but some of those same people claim a photo is pin sharp when it is not either. Not that easy if it effects a number of shutter speeds and it waste time having to select new ISO values if you are in the middle of a shoot and you need to avoid certain shutter speeds. That wasted time could be losing you photos and if your a pro, money.

I didn't mean if you go look for it in the photos, I meant if you try to shoot photos with shutter shock effect visible. It only occurs under very very specific situations. Yes, once it's there, obviously it's visible. But as many many many user reports have proven: under normal usage you won't encounter it. Normal here meaning: 1- don't use lenses with IS from another brand, if you have to, disable IS. 2- Always shoot at more than 1/f 3- Don't be an ass about it.

With long lenses I usually use support like a tripod or monopod, and when using such camera supports aleays have IS switched off. I discovered long ago that I get sharper shots like that. I also discovered via careful experimental checking of shutter speed ranges that it wasn’t related to focal length, it was simply that at shutter speeds lower than about 1/300th, with any length of focal length over about 200mm, I couldn't get the sharpness I got outside that danger range.

People insisting there is more to it than this are the people who went looking for it and thought they had found some dealbreaking issue, which it is not, by far.

It might not be deal breaking to you but it is to other people.

Which "other" people are you referring to, the people you are imagining?

Some of them will be people like me. Twenty years ago I didn't know about mirror shake. I discovered it trying to shoot long exposure murals in a dim church. My SLR didn't have mirror lock up. I decided then that in future I'd avoid cameras with mirrors which didn’t have mirror lock or other means of avoiding mirror shock problems. About three years ago I discovered that my problems with lenses over 200mm and shutter speeds less than 1/300th were probably shutter shock. My recent acquisition of a camera with switchable mechanical & electronic shutter proved it conclusively. Being able to switch off shutter shock has made a huge difference to the versatility of my long lenses for wildlife photography. In effect it's given me the equivalent of several extra stops of aperture on my long lenses.

So for me now any kind of mechanical flappery in a camera is a deal breaker. On the other hand I know several professional photographers who’ve never found either of mirror or shutter shock any kind of a problem. They simply don't do the kind of photography which shows up these problems.
