Or like when the dentists make a night guard for your teeth to keep you from grinding them at night. They make an exact plaster cast of your teeth which fits perfectly. As Pileatus says above, though, you can use your hands cupped around your binoculars to form eye cups that conform to your face.Denco
Like custom ear plugs for professional motorcycle riders! But I believe even they are costly.
Could you post a photo of your modified eyecups, please? I'd really like to see them.
Well, I'm talking only about my personal experience. I've read experiences from other forum members and they seem to be happy with them. In my case, I can appreciate the incredible design of the Leica, its awesome optics and the sheer quality that it oozes. However, when in use, the whole experience is jeopardized by the narrow eyecups (and the double hinge doesn't help). But that's just me. I was shocked when I discovered how easy and relaxed the view though the Nikon 7x20 CF III was, and then again by how "un-8x20" the Canon 8x20 IS feel.
Yarrellii... I remember some binoculars with low magnification and big exit pupils, that theoretically should have given me a relaxed an easy view, but that was not the case. I can think of the Optolyth NG 7x42, that with a 6 mm exit pupil and low magnification proved to be finicky when it came to eye position and prone to blackouts: it had some pretty narrow eyecups. The 7x35 Leica Retrovid wasn’t that bad, but the eyecup size was the deal-breaker for me. I loved the view, but couldn't use them comfortably. I sold them ...
I have some sympathy with this as I used a pair of Dialyts with the fold-down eyecups for 26 years, but my experience when reviewing a wide range of binoculars since then has made me wonder if I was just lucky with the Dialyts because I have certainly been grateful for eyecups with more than two positions to find the place where I could see the full fov and without blackouts.Call me old-fashioned, but I still like the old fold-down rubber eyecups of the old Zeiss Dialyt series (8x30 BGAT*P, 10x40 BGAT*P, 7x42 BGAT*P and so on) a lot. Simple, straightforward, nothing much that can go wrong.
OK, you can lose them after you screwed them off for cleaning the lenses, but that's about it.
