Makro-Symmar 120 at infinity and the 2.8/28 reversed and almost touching the front of the lens.soldevilla wrote:Hi. What is the optical design of your assembly, Robert?
Macro Symmar is focusing to infinity and then you superimpose the Componon? It is assumed that an enlarger lens works best when the distance to the focus from the front and back is short ...
I already have some tests to do next year.
Its sharp at f2.8 but a tiny bit better at f3.1, half way between 2.8 and 3.5. f3.5 is softer. Corners are perfect at f2.8-3.1.
