I have been fortunate enough to get to test this out for a little bit and, I can say that allthough the apature cap is not as tunable as say an iris set up it is by far faster to switch from close up work to full exposure and also provides a setting that the iris didn't, the ability to protect the tube from excessive light preventing damage to the tube. all in all they guys at OHC have done it again.
