Some haze.Hoya 7.5 deg marked 7.55 deg measured,Hoya good eye relief for an EWA binocular. But I don't wear glasses with binoculars.Minolta 7.8 deg marked 7.8 deg measured.All three good for astronomy.Minolta shows much fainter stars than the other two, although Swift has some internal haze.Minolta exit pupils round, other two squared off.I didn't bother getting Swift cleaned, as I prefer the Minolta.If someone wears glasses with binoculars the full field of EWA may not be seen.I also have a Russian EWA 10x50 Wide field but but mechanically it is poorly made.Also a 1960s or 1970s Korean one that is even worse. Poor optical quality, shoddy build.The Minolta 7x35 Standard MK has a measured field of 11.05 deg.The 8x40 Minolta Standard MK. Marked 9.5 degrees, measured field 9.4 degrees, but I think that it may be actually 8.1x40.Swift HR/5. 8.5x44.  8.26 deg measured.Swift Condor SPWA 9x,42 Extra wide angle 140m at 1000m. Multi coated optics (Not FMC). Round exit pupils.1990 Japan.Similar to 8.5x44 HR/5.The Condor is nice, fairly light weight. I can't remember what the measured field was.(Measured field of 9x42 Condor 7.72 deg compared to claimed 8.02 deg).I think that the Swift Audubon 10x50 has a 7.0 degree field?</blockquote>
