Unknown master lens


This master lens is a converted MC Rokkor-PG 50/1.4 without diaphragm and with fixed focusing (at infinity). It features a custom made fixed focusing grip with a slot, where a slider can be inserted. I have no confirmation, if this lens was a genuine Minolta master lens, or if it was custom made.


I own the F8 slider only, but there may have been some more sliders. The aperture ring is present, but not linked and it lacks the clicking mechanism.


The custom front end is perfectly machined and engraved with a number 117 - a serial number?


The beautiful machined slider.


Once again no pre-set pin, but else a common MC Rokkor from the back view.
