This is not scientific test, just quick test for my new Voigtlander APO LANTHAR 90mm f/3.5 MC Leica 39 screw mount compared to my  Leitz Elmar 90/4 Leica M mount. Both has silver body, beautiful.
Voigt condition is like new body & glass, while Leitz's body like new too but glass has cleaning mark ( due to my shots this isn't affect image quality ).

The elmar has longer body than lanthar

Lanthar's body is fatter

Lanthar has 10 blades

Elmar 15 blades

APO refers to a type of lens construction that reduces color fringing, generally APO lenses are more expensie than other lenses in same type. Lanthar as far as I know refers to Lanthanum material which being used to build this lens.

I'm impressed by it capability to control contrast between bright sun area and shadow area in this picture

back light? No problem :D
