This 92/2 conversion looks so professional, not like a Frankenlens at all. Nice job. Using the Chinese helicoid makes sense. Was it 58mm diameter or 42 or 52? And maybe a 30-90 extension?
I want to put a few projector lenses in some sort of mount. I'm thinking I'l cannibalize some junker long zooms -- keep the A-mount, the aperture and use the zoom mechanism for focus. Maybe pull the existing optics (or leave rear group), since I'm mainly interested in the projector lens performance. Seems like they were made for macro.
I'm not interested in reinventing the basics like mount and focus movement if this will work. And I can solve my guilt problem over not fixing these junkers that I'll never use anyway.
Am I too lazy? Any comments on my wild ideas are welcome. Anyway, I have two nice projector lenses in my parts bin, a Minolta P-Rokkor 100/2.8 and a Leitz Colorplan 90/2.5. So this gave me the push to get it done. More later..
