LD lenses vignette less than 28AD
There is no issue if vignetting with the LD mount until you have the dome at that point you could experience some vignetting but the same is true for the m67 lenses
The 28AD works ok with the RX but the diopters ucl165 start working around 70mm equivalent and two stacked really only work at full zoom
If that bothers you the AD mount is not for you
People at obsessed by vignetting but don't look at optical quality enough
The UFL165AD vignettes plenty until 35mm but the lens has no fringing and very sharp corners
For what concerns using those lenses with housing I would only trust this on recsea and nauticam housing
