Hi,
As I have tried a lot of binos in the past few years, I would say about half of the binos had blackout. Binos such as Nikon 8x32 Premier SE and Leica 7x42 HD had just too much blackout. The thing is that these are top of the line optics but the blackout is a deal breaker for me. My question is how much blackout you guys put you with ? do you tolerate it because the optics are excellent and live with it or not ?
Edit: I should have mentioned the binos above are specific to me, others may not have blackout issues with these particular models, any models in general I am asking.
My understanding of "blackout" is too much eye relief. Because of my facial dimensions I rarely experience this...and I don't wear glasses.
I have run into several situations where I don't have enough eye relief so you may consider that an equal frustration for the folks on the other side of the eye relief spectrum.
I can see where either situation ruins opportunities for folks to experience some excellent glass. I wonder why manufacturers don't allow for a wider range of eyecup adjustment to compensate for both ends of the eye relief "spectrum".
With 17mm specified eye relief, the Ultravid doesn't seem to have a blackout problem. I had problems with the Swift 828, which has 20mm eye relief specified, until I learned the MOLCET. But then, what's specified isn't always true!
