[QUOTE="FrankD, post: 1297902, member: 18544"] Hey now. That is not a bad idea. I wonder how many queries I would get if I took the Promaster badging off and relabeled them with a Swaro Eagle. I could tell everyone they were the new EL EDs! ;) To clarify, the FL is exceptionally sharp in the sweet spot but the sweet spot only covers about 50% of the field of view (all be it the largest field of view for a modern 7x). The next 25% is slightly degraded by still very close to the sweet spot sharpness. The outer 25% suffers from noticeable astigmatism. The demo Promaster ED pretty much mirror this sweet spot/astigmatism characteristic. The newer unit I just received from Doug has the same sweet spot sharpness as the original but the size of the sweet spot is noticeably larger. I would say it covers more like 70-75% of the image now with a gradual degradation of the image over the next 15% with the outer 10% showing noticeable astigmatism. Steve,....also I posted on both opticstalk and the firing line after you did. I have been a member of opticstalk for several years so hopefully my comments will reinforce your own.
