I'm coming to you as a recent A7 convert. I just got the A7II in my paws yesterday, and so far I really like it.
But there's one usability issue that I'm really having a hard time coming to grips with. I am used to shooting with my Fujifilm X100S as well as the Olympus OM-D, and one of the buttons I used the most on those bodies is a toggle for turning off the monitor on the back of the camera. The Sony has a button option that makes the monitor black out, but it's still on. I'd like to be able to add the FINDER/MONITOR option to an Fn Button, and really, how hard could that be?
There are times I don't want the monitor to come on at all, and I don't want to have to dive into a menu to do that. If it exists at all, it would be nice to be able to add it to a Fn button.
But even when I do go into the menu and hit that button to turn off the display, when I hit the playback button to review images, it doesn't turn the display back on, it plays the image in the viewfinder, which is not ideal.
It just seems like a really underdeveloped option for such a great camera. If we could get an Fn button to control the viewfinder, I would be so, so very happy. As it is, it's a pain in the ******. One I'm willing to make for the sake of great image quality, but a pain nonetheless.
