Does it make any difference if a filter is mounted backwards to usual orientation? I have a Tak adapter that presents an m48 filter thread on the rear of the adapter meaning the filter gets screwed on bass-ackwards.
Does it make any difference (it’s going to hold a UV/IR cut filter) or since the light will be going through it anyway won’t make a jot of difference.
If it does I’ll just get a custom one made
