Yes, they are self focusing as I understand self focusing. You do have to adjust the distance from your eye center to center (pupil to pupil). You do this by grasping each barrel firmly and moving the barrels closer together or further apart until you see a single circular field. Everyone's eyes vary in distance dimension from center of left pupil to center of right pupil. Once this is done you just view an object and there is no distance adjustment required. The next time you use them, it is suggested that you recheck or reset that position as someone else may have used them, or a weight on the binocular may have moved the barrels further apart.

Yes! These tubes work really well. You can change aperture and auto focus with these tubes.

No these are high quality SAFETY glasses to protect your eyes. They are ANSI rated and self tint when you wear them outside. If you are looking for glasses to cut glare at night while driving these are not them, try looking for lenses with a full YELLOW tint.

I don't know but I don't think that you can do anything but manually focus with these lens babies... they are not designed to autofocus so there is a bit of a learning and experimenting with them till you get the look that you want....each aperture ring gives you a slightly different look... so you have to know where to direct your focus.. and that has to be done manually....

Lily - I bought them and never used them. They are junk. You'd be way better off investing in a precision set of adjustable glasses like Superfocus.

I've never encountered a pair of binoculars with 0 to infinity focus capability. These are not an exception. They do work well in low light.

I don't think so, I've been manually focusing since the day I started using it.....My suggestion, go to photography store and ask them WHICH adapters allow autofocusing...

They are bifocal. The upper part of each lens has no correction/magnification. The "reader" correction/magnification is located only in the bottom part of the lens. Therefore, I'm guessing that these glasses are probably not what you're looking for.

Yes. They are lightweight, sharp of focus and easy to focus. The field of view is great for Alaskan wildlife.

Yes they are. 2.5 and 3.0. By the way, these Dewalt bifocals (I have 2.0) are great. Very Clear.

Not sure but they are not super heavy. You might want to check the specs. As far as worth the money, YES! I love them!!! They are perfect for me. They are clear and easy to focus.

Yes, they are. Be careful though - they are so sharp it's easy to cut yourself.

Yes they would. I bought these for my three year old grandson and he uses them with no problem. You don't have to focus them, every thing is in focus. All you do is look through them. They are great for bird watching, or any thing that move because regardless of the distance object are in focus with out the need to zoom in and out.

Hi Patti,They are crystal clear for long range viewing. The optics seem to be of exceptional quality for the price. They are, however, somewhat heavy but still easily handled. I'm on my second pair (the first broke while close focusing to the minimum) and this unit works very, very well. For the price it is an excellent buy if you can accept that they are mage in China.

Unfortunately - I don't believe that these binoculars have the ability to focus -I personally have found their performance to be less than satisfactory
