It really depends on the focal length of your lens. What type of lens do you have?

For macro only, this is effectively an extension tube. Canon fd to eos must have a glass element.

Make sure the current sight is graduated at the correct distance. It should be fine.

Anything closer than about 50-75 feet will be out of focus. Beyond that they are great. These are auto-focus and you can not adjust the focus manually.

You have to use manual focus with all adapters. Well not all per say but the ones that have electronics for the autofocus cost alot. we are talking 300$

Try putting your camera in manual mode. AF doesn't work with this adapter, so use it as a manual focus.

As long as the collimation tool fits snugly in the focuser adapter you should be fine. If there's any "slop" at all your alignment might be out.

Close focus is 25 feet, a little fuzzy at 20 ft. I use mine to spot bullet holes in a target when shooting with iron sights at 50 yards. Works great!

I was able to fit in my smaller eyepieces in the adapter. There is a knurled screw that will hold the eyepiece in place. I've also found that it isn't designed to be used as a primary focus adapter unless you have a low profile focuser. Has anyone been able to find any larger eyepieces that will fit in the adapter?

This is strictly for macro. Focusing on anything that isn't at the closest focal point is impossible. It is also recommended that you use a lens with a shorter zoom level. This is basically incompatible with my 250mm. I can only imagine how much worse it is with a 400mm.

Don't worrie. It will eventually fail before it gets to focus. POS for sure. And given the 4 prong connection, not interchangeable with others

I used the adapter on a Nikon 1 V2 and it worked great with multiple Nikkor lenses; 50mm/1.8, 28-300mm/3.5-5.6, 200mm/f4, 300mm/2.8. As the literature says, with certain lenses you'll have autofocus, and some not. Worked fine for stationary subjects.

That's what I have and it didn't work with mine. Now, I wasn't sure if it was faulty or if it needed another attachment. But it was all out of focus and not right at all.

Turn the little black thing on the end of the lens a little at a time, that will focus. Then u can mov

There is no focus. Only adjustment is for the width of your eyes. That's it. They work fine for me. Maybe you need to use your glasses.

YES, Minimum Focusing Distance: 1yds. YES, IF YOU CAN USE IT WITH GLASSES.YES, YOU CAN USE IT WITHOUT GLASSES.

Yes it will... I have the basic 300mm which focuses at a little over 5 feet.. with this attachment I can focus at a little over 3 feet...

It depends on the lens ie:if the lens f/1.4 that's the max at open closed f/16 and this adapter is only effective on crop sensor
