Today I received a red dot finder wich I intent to use with 500-1000mm lenses.
It turned out that it has a metal cold shoe, may I mount this on my Sony A7 or would I risk some damage by shorting circuits?
EDIT: I already thought about protecting the contacts with tape to avoid shorts.
I made a macro of the actual situation:
It seems there is a gap between the contacts in question (indicated by the green arrow). The cold shoe should be shifted along the yellow line and pulled up by a mouting screw, so the finder mount must be stoped at the red arrow which should be possible to verfiy by meausring with a caliper?
This shoe of a TTL-flash looks trustworthy:
The contacts were designed to match.
The red zone looks dangerous to me, probably it can be mounted other way around and gets blocked at the red arrow from the 1st image. Otherwise there is a lot accessories offered with metal cold shoes and other people don't seem to worry as I do. It 'could' also be that it is safe to mount it because it would take place above the contacs (following the yellow line in 1st image) but I don't dare to risk damgage because of 'could'.
