Message: <blockquote data-quote="Kevin Purcell" data-source="post: 1709546" data-attributes="member: 68323">I like FLs too but one area they could improve is edge of field sharpness (edge astigmatism) i.e. I could see a field flattener in their future, for example, as the obvious change.And although it's easy to say that that would be a significant redesign of the optics to make it all work together (and yield the parameters they want like big FOVs).The 7x still has the biggest FOV, the 8x is up there but not huge and the 10x is now bested by EDG (though the Leica and Swaro are similar).The other question for the 42mm might be hersey for Zeiss fans: do they keep using Abbe-Koenig prisms which make the bins longer even though they can now make dielectric mirror SP prisms (like they use in the 32mm bins) that are of almost equally high transmission (the AK will always be just a bit brighter than SP but not so much that it makes a difference). That would be a major change for Zeiss but it might bring Leica sized bins.But given their upgrade cycle I suspect perhaps not for a couple more years?Perhaps the current bins are good enough? Shock! Horror! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></blockquote>
