if you look down the lens and move the aperture ring - you will see that the iris will move to anywhere you like it.

In other words you could do exposure is steps of 3 or even 6 between stops if you are nimble fingered.

My Pro S has click stops every half stop; I'm using the 127mm lens but all of the lenses are the same.

Patrick,

The KL lenses on the current Pro SD have click stops at full apertures, but the aperture can be set anywhere in between. Although, I do not have any older Pro/Pro S series lenses to check, information I have indicates that the aperture ring has full and half click stops, but I cannot "guarantee" that.

Just a simple question. Regarding the lenses for the original RB67 Pro and the Pro S, do the aperture rings have half stop settings or only full stop settings?
