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?
