Of interest at NEAF was the 100 degree apparent FOV, 13 mm FL, 2 inch EP that Al Nagler introduced. The "Ethos". On his 101, it was absolutely pure, with no abberation to the edge of the very, very wide field. This will likely make 13-17 mm, 1.5 inch wide field EPs irrelevant. These will come out "in the fall".
I'll get a photo up tomorrow.
