Meyer Domiplan 50mm f2.8
I received my copy from Ebay. Yep, it was full of fungus and the aperture doesn't work because a piece is missing and the ring is damaged. Typical Ebay purchase.
So, it is any good? I cleaned the fungus out but I couldn't do anything with the diaphragm. I shot these pics at f2.8 and they are good.
I can honestly say this lens is usable at f2.8, not like i have a choice, though. It is sharp at f2.8. Color rendition is a bit cool. Contrast is good. Fringing is well controlled. There is some bokeh fringing. Bokeh is very busy.
I'd say it's a steal at $20. If you see one that works, buy it.
