Thanks! :-)

@Dirk: The lens is modeled and I used images for the Iso wheel at the top.
After aligning the numbers on the lens circumference, numbers were extruded using "both sides" options.
This way it would stick out of the lens completely, also making it easier to select when doing the Boolean operations.

@Armin: It's hard to say as it was a free time project, a little bit from time to time. I would say around two days if I put it end to end.
While doing the project I realized the unseen complexity of it, those people at Minolta sure put a lot of love in their device.
