Does anyone have experience with this older setup? I can't find any specific reference to it.
Subal suggests a 40mm extension with the 8 inch FE port and a +2 diopter.
When assembled, the lens looks like it sits too far forward in the dome.
I am specifically wondering about stacking a 15 + 33. It looks better, but I am wondering if there is anything I am missing.
Also is the +2 diopter enough?
I'm going to try it in a pool, but looking for advice.
Thanks in advance for any input.
