Maybe this is a dumb question, but I've shot Canon forever and Canon hotshoes and the mating bit on the Canon flashes arrive bare.
My Sony A7rIII came with a little plastic bit snapped into the shoe, and the Flashpoint flash I bought for the camera also arrived with a little plastic clip on the foot. What are these for? Am I really supposed to not lose them, because I have a feeling I will lose them. It's bad enough figuring out which pocket I stuffed the lens cap in when I started shooting, these little plastic caps are going to be really easy to lose.
So, what are they for?
