What about bokeh, loCA and flare resistance of this lenses?

[/quote]

These lenses were designed to be at a specific distance to the subject, and of course a specific distance to the film. Either reversed or "the normal way around".



I can not yet try the 28mm f1.8 one, as I lack a 40.5mm lens thread adapter + whatever else is needed to get it to AF-mount.



The 55mm f2 I am trying with a make-shift self made adapter, which is thicker than necessary, acting as an extension tube and instead of giving 1:4 magnification, reaching almost 1:2 magnification.



This lens was designed for photographing merely totally flat subjects. However, its bokeh is SMOOTH, especially for a 55mm lens. Very surprising. I really like the character of its bokeh.



This lens also was designed to be used with a very narrow spectrum of light, a monochromatic green (e-line). As such, it never was meant to be used in colour photography. I do see some LoCA evidence, but I am using it with an "extension tube" so I am not yet clear on how it will perform either at 1:4 or reversed (making it 4:1). It behaves quite well though, LoCA wise.



I do see some coma like distortion towards the edges, which may disappear when using it towards 1:4 or reversed.



At 1:2 magnification, it obviously will not be used in situations where lens flare will appear, so I can not tell you. It has very advanced coatings (especially for the time, 1965), and I have not noticed any bad veiling or loss of contrast yet with backlight.
