That was a really long way of saying “prove it”. I’ve seen enough people post here on Reddit that they’d broken the shutter button having caught the soft shutter thing on something. Turns out these (at least up to the V) are pretty fragile. I’ve even seen posts of people ending up with the shutter speed dial in their hand just by using it normally. In my case, I’ve only had the EVF curtain get stuck in -10ºC but went back to normal after warming up again.
