Message: <blockquote data-quote="brocknroller" data-source="post: 1864545" data-attributes="member: 665">Ron,Thanks for that detailed "guess". It would certainly explain the ED2. I already knew from the School of Hard Knocks that not every bin comes off the assembly line perfectly collimated, but I didn't realize that companies made purposeful decisions about how to collimate bins to enhance the 3-D effect. That's very interesting. I don't find the sweet spot lacking on the ED2 nor am I disappointed in the resolution, so for me, it's the best of all worlds (except for the sometimes pesky flaring). I was watching some ducklings at the local pond this afternoon with the ED2 (recently, a very noisy gravel pit moved in right next door so I'm surprised they're still there). I was amazed at the fuzzy "downy feather" detail on the yellow ducklings and the feather detail on the hens and the more colorful drakes. The guys and gals hang out together. The females were in the water with the youngins while the males were all sleeping on the beach (sounds a lot like a human beach <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />. I knew that other factors such as field curvature and astigmatism influenced the perception of 3-D. This is what puzzled me about the enhanced 3-D effect in the 10x42 SV EL, which has virtually no field curvature or astigmatism. And I don't think anyone is going to complain about the centerfield resolution or edge performance on the SV EL. So in this case, the enhanced 3-effect doesn't seem to be caused by convergent collimation unless the field flatteners overcome the trade-offs you mentioned?  Sharp to the edge, super sharp on axis, enhanced 3-D perception, and now a report that the 10x42 has less "rolling ball" than the 8.5x model. This is piquing my interest in the 10x42 model. Of course, I'd have to use a Finn Stick to gain full advantage of the magnification, but it sounds promising. Now if I change my name to Joe Buck, buy a fringed suede leather jacket and cowboy hat, and find some lonely middle-aged women who need comforting, perhaps I can come up with the scratch to buy one! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
