Hi all,
Does anyone know the optical formula of the Konishiroku Hexanon 48mm f2 lens that was found on the Konica IIa and later fixed-lens rangefinders?
I've looked through all my usual spots and haven't found the diagram anywhere.
Thank you!

Pretty sure it is the same lens at the Konica 50mm f/1.9 in M39. 6 elements / 5 groups, Voigtlander Ultron derivative.

This was my hope. Perhaps someone here has a diagram or has taken apart both lenses.

Click on the diagram link on this page. I absolutely love the 50mm f/1.9.

Hey, do you happen to know what the filter size is for the 48mm f/2 Hexanon on the IIA? Or does anyone know offhand? Thanks!

35.5 filter is what fits the Konica IIA and Konica III with the 48 f2 lens. Great cameras by the way!
