Yes, I know you don't make one. But I could use something like that.
You guys are very good engineers and I bet you could come up with an L adapter that could be turned over to fit tripod offsets on either side of the lens.
I have a 20mm T adapter and I only use one side :-)
ALSO -- and this is the point of this missive -- the T adapter is just long enough to prevent me from opening the battery/ card door on my camera so I have to take the T adapter off each time I want to take the card out or change the batteries. So then I have to check the alignment each time. Kind of a pain...
I was thinking about sawing the end off the 20mm T adapter just so I could open the battery door. I'm a little reluctant to do that since I don't know if the T adapter would survive the process as a still usable part.
