Ok, I know Dagor and its clones (particularly Collinear) have only 4 air-glass surfaces, so the light loss would be small compare to other uncoated lenses. But how do they perform on chrome and color negative film? Are the result comparable to a coated (single, or even multi) lens? I have 150mm Collinear and 210mm Dagor. I tended to sell them to get a coated one for shooting on chrome and color negative film, but now I'm considering keeping them, if the result should be fine.
Any one has experience?
