Resolution Difference Rodenstock 120 Makro/Schneider 120 Makr0

[rolf_g._katzenstein]

In respect to the current 120 Macro offerings from Rodenstock and Schneider, the specs notwithstanding, I am curious about opinions regarding resolution and appropriatenes for use in the macrophotography of flowers. I'm using a 4X5 and will probably try the selected lens on a 6X9.

Rolf: you say nothwistanding...Well in the design of these lenses

their maker endeavors to achieve certain technical specs. Those specs

are to the manufacturer a measure of achievement and for the user a

more reliable guide than user tests often conducted under conditions

that lack even the minimum technical rigor for any decent lab.

Learning to read those specs spares you from hear say, mythmaking

and often conflicting opinions. You may 'hear' differently from this

web site but of the many Zeiss, Schneider and Rodenstock lenses I

have owned I have yet to find a lens whose performance was

disappointing. Taking the time to study that stuff has for me been a

very worthwhile, money-saving and liberating effort.

As for the lenses you mention, the performance of the Schneider

lenses at close distances, i.e. 1:1, 1:5 and 1:10 is published.

Similarly for Rodenstock if my memory serves me right. Both companies

make outstanding lenses and the difference between them is not worth

worrying about.

Good luck!
