Perhaps I've lived a sheltered life but I've never had a DSLR, or 35mm film camera for that matter, that did not have a built-in eyepiece shutter. That may soon change and I'd like to know the best way to deal with it. For photographing wildlife or action there's no need for an eyepiece shutter since your face and eye blocks light from the viewfinder. For landscapes I use it 100% of the time if I'm not using live view, and I don't use live view very often. Unless environmental conditions are nice and the scene will remain as it is for a while, which is rare, I want to work reasonably fast without lots of fussing around. I can't imagine being in a hurry, in the spray of a waterfall, blowing sand, or countless other "not nice" conditions while having to remove the eyepiece surround and replace it with a rubber cover. I also can’t imagine not losing one of these pieces eventually, or trying to get gaffer's tape to stick to a wet camera, or using live view when there are beads of water all over the LCD or dust blowing into your eyes.
I'd just like to find out how people deal with the ridiculous lack of a built-in eyepiece shutter on many cameras. Has anyone found a clever solution, like something that slides into the hot shoe and flips up out of the way? I don’t care what it looks like but it has to work. I know this seems like an insignificant issue, but exposures that are off due to stray light entering the viewfinder are as significant as it gets for a photograph.
Thanks.
