Hello to everyone,
I would like to find out what in detail are the differences between
the Zeiss S-Planar 5,6/120mm and the Zeiss M-Planar 5,6/120mm. From
what one can find easily is (blinkingly obvious) that they claim that
the M-Planar is optimized for Macro Photography but on the other hand,
they also say that the S-Planar is excellent for the same application.
Looking at both lenses, I do not see an obvious difference - is anyone
out there who is knowledgeable regarding their differences? I could
guess that both lenses are identical but the M-Planar is regarding
spacing and setting of the elements more optimized for macro than the
S-Planar..or is there any other known difference?
Thanks for your replies and suggestions -
Georg N.Nyman |

Hi Georg,
Quote: I would like to find out what in detail are the differences between

are these lenses for the Hasselblad system? If yes, I find
and S-Planar 5.6/120mm and a Makro-Planar 4/120mm where the
S-Planar is the predecessor of the Makro-Planar and the
latter is the newer version and one f-stop faster lens with
- according to the datasheet - optical properties very similar
to the S-Planar.
Best regards

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

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
