Michael Mutmansky has indicated that the 240 Componon S would cover 8X10 according to his calculations on the Durst 138S that he converted to 8X10. However, I don't believe that he has used this focal length after the conversion. He did mention the possibility of light fall off with the 240. He uses a 300 mm lens, to the best of my knowledge. I believe that Michael's concern about coverage was when enlargements approach or exceed 20X24 print size.

I have intended to use the 240 Componon S with one of my Durst enlargers if I decide to convert this to an 8X10 Azo enlarger with a UV light source. Thus far that is another project awaiting my time to devote to it.
