Title: Using an old 4.5/115mm Printing Lens
Post by: Dr Klaus Schmitt on July 05, 2019, 08:51:25
A few samples what this Tomioka f4.5/115mm printer lens can do...(shot fully open):

and yes, it is nearly apochromatic even fully open...(cf last pic)

impressive performance, and strange shot (last pic). I guess there is no diaph & no focussing ring?

Thanks for these Klaus
Wow - some intense colours here!

I like the first one and the second bee one (on the lavender) the best

It indeed has a variable aperture (iris), but like an enlarger lens, which it actually is, there is no focusing (I used a helicoid).
That "strange" last shot is only for CA testing purposes, guess you did not know that water works perfectly for that ;-)

Thanks, indeed it has impressive colors and quite good sharpness + contrast!
