Title: Rodenstock 35mm HR lens test, and Rodenstock 45mm
Post by: jing q on March 10, 2008, 04:45:38 pm

So I finally got my whole setup working today and had some time in the hotel..and both 35mm HR lens and 45mm f/4.5 digital lenses from rodenstock in hand so I did a little testing.
Shot on a Silvestri Bicam. Attached below are the full scenes for each lens for download, on this post are 100% crops

First up is the 35mm HR. Will post up more later.

f/4 1/250th

f/5.6 1/125th

f/8 1/60th

Amazingly the HR lens is really at its sharpest wide open at f/4, and then becomes slightly softer
but still blows the 45mm out of the water
For comparison sake, here's the 45mm at f/16th 1/30th of a second
f/16 because this was the sharpest it got out of all the apertures I was trying it at

These are views of San Francisco that I haven't seen for sure. Definitely a big difference between lenses. The full image with the 35mm looks great but I was surprised that all the 100% crops look a bit soft.  How are you processing and what back are you using?

Thanks for posting, but just wanted to point out that these were shot thru a hotel window. That seems like it would kinda negate all that great glass.
