Even just looking at, the 16 blade iris is something to behold. Does produce a lovely circular aperture rather than hex or octagonal.
Smooth operation no click stops on the aperture ring, infinitely variable which works very well with the M8 metering when in manual. You can get the exposure just as you like. Distance scale is in imperial "Feet" only. Close focus 3.5 feet. For the Leicaphiles out there or the curious the f stops work in reverse. f16 to the left f2 to the right. Also for those that care, the lens collapses into the M8 with not issues.
I can see me using this lens more often as I am very happy with the results.
On the M8 it looks like this.
Hmm blades.
