New Apo Tele Xenar 400 mm Compact2000 versiongreenspun.com : LUSENET : Large format photography : One Thread
I have seen this new lens listed on a well known retailer web site. Has someone informations on it's opening, shutter size, weight and overall performances?

Paul: I seem to recall that this new version was announced at the same time as the 210 SymmarXL. I think the Lotus View camera site had some info on both lenses.

Well, www.schneideroptics.com has new information on this lens and its f12/800mm variant replete with MTF curves and performance data.

Erik, I could not find the info but for the older version. Where did you find it? Glenn, thanks! Yes this web site has even a picture of it. I have had also some good infos privately, thanks Jesper.
F 5,6 , Shorter focal flange, 912g , more affordable, but still a big lens in Copal#3. (For a while, I believed in a miracle and a Copal#1 even at f8, which would have made it more compatible with my somewhat flimsy field camera).

A 400mm f5.6 in a Copal #1!!!! Only if they applied some of that aspheric magic to the design.

Is there a real benefit in having a 400 mm with a f5,6 aperture instead of f8? I'm sure it can be nice if the lens is used in the studio for 5x7, but what about landscape photography in 4x5?

Schneider posted complete details on their German web site today!
includes MTF and mechanical schematics
