This is from a recent project where I needed a 90mm on my DaYi 6x17cm camera. My 72mm was too wide and the 120mm too long. Thus, a 90mm.
As I had a near mint condition all-black Copal 0, I found a set of Sinaron cells that went straight in. Problem solved!
Just an amazing lens. Outstanding coverage and sharpness. This is my first Rodenstock lens. It definitely won't be my last.
The project is now done, as is my need for a fixed 6x17cm camera. I'm going back to my Shen Hao 617 now, so back to the 72/120mm lens split.
Please note that this is the f6.8 lens, but the aperture scale is for an f8 camera. I worked around this, but have a scan of the f6.8 aperture set if you need them.
US$330 +shipping from Oz. I'll cover the PayPal.
