Here's a problem for all the mirrorless fans. I do a lot of work under high powered strobes for product, fashion and car photography. Although I usually shoot with MF or DSLR, I bought a mirrorless camera last year to play around with. A lot of the time the lack of a viewfinder doesn't bother me but this one issue has got me stumped. When shooting with a fairly small aperture in a darkish studio the electronic viewfinder is completely black. In a way this is what I would hope for as I aim to cut out any ambient light but it also means that it is impossible to focus without adjusting the aperture first. This seems like a major problem for strobe shooting or is there a simple work-around that I don't know about? It is surely a problem anyone shooting mirrorless with strobes is going to come up against.
