It is simply a smart idea to have one of these small little protective caps for your camera. The protection it offers [when accessory shoe is not in use] against damage and dirt, is well worth the money spent on it.
Review 2 for BS-1 Accessory Shoe Cap
Sometimes It's the Little Things...
PostedMay 9, 2014
Sometimes it is the little things that count! This small little shoe cap, no bigger than my thumb nail slips right into the empty slot of the accessory shoe on the top of the camera to keep it covered when not in use. It keeps it dust free, dry, and overall protected. Everyone should have one, and if you lose it, get another. It's that simple!
