At any of zoom settings, will there be any problems focusing on a 25 yd range?

I don't think so...we haven't used it enough to be sure, but we do look across the valley and can focus clearly. It's got to be more than 25 yards.

I had trouble getting a clear focus at the 12+ power range even though I had it on a tripod. I was watching a golf tournament about 250 yards away. I would say no.

Yes. I just tried it. You can also focus with the ND side to side switch. Also, like ryuxis stated, the zoom is considerably slower.

no, there does not seem to be any zoom or focus options. it was simple plug and play install.

You can focus to within eight inches away of your subject. But remember that this is a wide angle, 24mm equivalent lens, so even at a close up distance, you will get more into your frame than you would with a longer lens. You must also be aware of potential wide-angle distortion.

I've shot at 100 yards with good groupings, the 3x zoom makes it so much nicer than the plain red-dots for distance. 200 yards would probably not be bad at all either, depending on what you are trying to hit.

Yes it will focus fine at 2 feet or even a little closer if need be. The field of view is appx 2-3 feet at that range.

yes, check your settings (resolution and stability and auto focus ) adjust accordingly and snap away

The range extenders do work very well with the manual focus but you lose the auto focus capability, which I try not to trust anyway. For me, using the magnifier just makes me pay closer attention to my focus and plan my shots a little better.

It is not a "fixed" F/2.8. It is a "constant" F/2.8 which does not change when zoom from 24 to 70. It still has the smallest aperture of F/22 that you can use to gain all the DOF you want.

If you are asking about about the minimum parallax adjustment, it's 25 yards.

It really depends on the subject and type of photography your shooting. I would suggest that you download the lens manuals for all your lenses and make your own decision. With the 25 you get greater magnification factor but less fucusing range. Also the 25 you have to get closer to your subject and may need a lens mounted ring flash for outdoor shooting in low light. I must stress that you do your research on all your lenses. Jerry Stahl

Yes this headband magnifier will be in good focus at 18 to 24 inch range. I am happy with mine. I spread butterflies using mine. I have no focus problems at 24" or much closer. For the price this magnifier is as good or better than much more expensive one.

You'd just have to know what M# is for 10ft, and what M99 minimum distance is, so that anything beyond that distance will be in focus. Trial, error and practice.

Most people have the 'kit' zoom. If so, set it at 19mm and use it for a day. Don't zoom. Then set it at 30mm, and try that. It's marked, coarsely, but you can get close enough.

Yes, but if you have a small error at 25 yards it will br agnified down range. Inothrwards if yay off center by 1/4" at 25 yards, you might not even hit the paper at 100 yards. I try to shoot close first, the sero in at 100 or 200 to get a trough zero. Once I have that bracket, I can scheck 25 yards, which shoul be dead on for left and right, and typically a little high at 25 yards.

As it has a variable power setting, it will really depend on at what range you intend to use it. The field of view on it's lower power is quite wide but natuaraly narrows as you zoom in. For mid power of about 5x or so, I would descibe the viewing agle as wide.
