Could somebody give me some info about the Rodenstock Ysaron 210mm. enlarging lens? ( Age, lenses/groups, max.f/., coating...)Opinions about the quality/results welcomed. Thanks.

If memory serves me right, the Ysarons are the older generation of

Rodenstock Rogonars (which are the new, improved versions). The

Rogonars and the equivalent Omegarons are basically four element

Tessar type designs, which while capable of better performance than

three-element lenses like the Trinar and Componars, still fall short

of optimum requirements. One, their definition is slightly lower than

it should be, even at the scale of reproduction for which they are

corrected. Two, they are slightly more sensitive to scale variations.

In other words, at magnifications other than the ideal scale of

reproduction there is a risk of quality loss unless it is corrected

by stopping down. The six element enlarging lenses such as the

Componons, Rodagons, El Nikkors and Leitz Foctars are generally

accepted as the best enlarging lenses.

If you have the serial number we can tell you the age.

The only Ysaron lenses currently being made are short focal length

micro film lenses.
