This is the amazing part to me - before I even got the 9x45 focused, I could see purple - big time purple. I remember looking at my wood owl-house out back, purple all around it. As I focused, the purple remained constant and a glowing rim around the box. None of my other binos show any CA on the box at all. I think it's the most CA of any binocular I've tried here at the house. The last ones that even came close were the 8x56 Dialyt and my old Nikon 8x42 Premier LXL's and I don't think the purple was that bright or prominent, at least not in the center.
Rather than "sensitivity" to blue/purple colors, I think some people just can't seem them at all. There's a term for that but it sounds pretty frightening and so I'll leave it at that

It was a tough day for Maven. The same day I got them, I received 1989 Nikon 10x50 Gold Sentinel porros, purchased for $93 with tax and shipping from an Phoenix, AZ antiques dealer. Zero false color on the owl box or anything else. Razor sharp optics, easier eye placement, less blackouts than the Mavens. Full 50mm of aperture.
You can't blame me for reacting the way I did to Maven....it was NOT a good day for Maven. The Gold Sentinel are still here and Maven's return/refund service is excellent
