Was researching the binos/LRFs and the description related to focus says "Fixed/Focus Free". I don't know how that would work. Called ATN could not get in touch with a knowledgeable person. Got a link to the manual, no method of focusing listed/identified and no other explanation.

Does anybody have any experience with these and what was the focus like? or can you explain how the "technology" works as I don't understand how anything can be in focus from 50 yards to 1000 yards. I didn't think it was physically possible to have optics in focus over large distance ranges. They specifically stated on the phone they weren't auto-focus.

Please refrain from telling me to buy leicas or whatever, or that they will be a POS, I already have a nice set of 10x42 leicas w/rf, I am trying to understand the technology. Thanks.

What power are these binos, Mike? Many old 6x glasses only needed to be adjusted for the individual's eyesight, not changing distances. Keeping the focal length short may have been part of the secret.

I have an early military Nickel riflescope with no user-friendly focus adjustment. Maybe they they reasoned that if you could get into the post-war army your eyesight would be close enough to 20-20 to set the scopes for that.

But I don't suppose the makers of your binos would have taken that course. More likely they have devised some way of evaluating the user's eyesight and/or point of visual interest and robotically adjust the lenses to suit.

PS: I've finally googled ATN LRF binos and see they are another world altogether. If they use lasers to get distances, it may be the laser engagement 'guesses' what you're looking at . . .

They are 10x42.

Thanks Mike,
As you might guess, electronic optics other than cameras are beyond my interests, ethics and bank account
