They adjust way too easily. The eye cups twist and have virtually no resistance at the extreme in, or out position and they slide past the intermediate stop points very easily too. I slid the binos with the eye cups at the 3rd stop point (almost all the way out) into my fhf pro-m harness and strap the lid down, opened it back up and the eye cups were pushed all the way back in. So I tried it again very gingerly, the eye cups stayed out, I walked around the house for 5-10 minutes pulled the binos out again and the eye cups were again pushed all the way back in. I don’t care for how easily the eye cups changed position and I wasn’t going to put up with a $1000 piece of glass that I had to adjust the eye cups every time I pulled them out.@ONE_3 , what’s the deal with the Maven eye cups? Describe the eye cup attributes that you didn’t like. I’m just about to order a B6, …. I think. Haven’t seen/held a pair yet. Thanks.
Don’t get me wrong, the adjustment wheel is silky smooth, the binos are well built, I liked the quality of the glass and the optics but I thought the zeiss conquest hd was just a smidge better optically and the eye cups have much harder stop points at all adjustment levels. The only thing that isn’t “as good or better” than the maven is the adjustment wheel. It’s adequate but I think the maven is smoother.
Hope this helps.
