    New Zeiss Victory SF !!!!!!

    As I understand it, this so-called "ring" is a distortion effect of the transition from fall-off of very gentle pincushion to astigmatic correction of the outer field? <cue the long lecture> If so, how could a tweak at the factory make this go away? David

    New Zeiss Victory SF !!!!!!

    Hi Rich, I did not realize that was you! 3 it is (and corroborated by the other Dave). I was very surprised to see the SFs there, frankly, and I wish I had spent more time with them (I was rushing off to a hawk watch). The brochure is indeed lovely; the kind of information some of us want...

    Similar amazement at Zeiss' use of non-Schott glass came up in this thread a few years back, regarding a video at the Wetzlar factory showing stacks of Ohara boxes. http://www.birdforum.net/showthread.php?t=239330 Really, all this essentialism about materials and place of origin is pretty...

    New Zeiss Victory SF !!!!!!

    I have not read every word of this thread, so perhaps this has been posted already, but Piergiovanni Salimbeni of Binomania posted some vacation comments on the SF (and what its competitors now have to do) in his August editorial: http://www.binomania.it/wordpress/?page_id=6488 Carry on, David
