Re: Zeiss S-Planar and M-Planar 120mm



Hi Dieter,

Thanks for your answers - these lenses are for the Rollei SL 66 (SE)
and both have a maximum aperture of 1:5,6
Your explanations sounds very logical - maybe someone else who reads
this posting knows the details about these two lenses
Best regards

Georg Nyman

Hi Georg,

short addendum to my own posting: S-Planar also seems to
be Zeiss's label for lenses optimized for copy work,
although it is found on some of their macro lenses as well.
Maybe it's a hint that an S-Planar sold as a macro lens
may be derived from the optical construction of a copy lens.

Talking about rodenstock, for example, I know that they have
macro/copy lenses (Apo-Rodagon D) derived from their enlarging
lenses and that they come optimized for different magnification
factors (1:2 or 1:1 for example).

Best regards
