Lens2scope 10mm 1:4 Eyepiece for Nikon F(DX) Lens, Angle View, Black

Works as advertised, great way to maximize use of your lenses and save space. It automatically opens the aperture up when you mount the lens so you get a bright clear image. Very small and very powerful if you have a telephoto lens. Great with zoom lenses. Usefull in finding wildlife to photograph.

Sweet, since I transitioned to digital photography I'm left with a number of 35mm lenses I had no longer a use for. I put the eyepiece on a 500mm mirror lens and it makes an awesome telescope as well as a spotting scope.

recieverd and it work pretty well.

Popped this on a 500mm mirror Nikon for viewing out my parents' patio in Montana. Makes for a sweet lightweight spotting scope. If I had dark skies in the summer I'd test this on some night sky objects but will have to wait for the fall for that. I'm buying a second one to have at home for birding and seeing what the tourists in my area manage to get themselves into on a local mountain.

It is a good idea product, It can turn the lens into a telescope. But I wonder it is a Kenko brand?

I put this on my Nikon 70-300 DX lens. It works very well. The focus is very touchy but that's a function of the lens not the scope adapter.

Wow... Much better image quality than I was expecting for the price. Its a very handy accessory if you have a long lens with a decent aperture.The only strike against it is the plastic build quality, particularly the flimsy tripod mount, which is too flexy to be useful.Thats not really a huge issue, as you can eaaily hand hold it with a moderate telephoto, but if you're using with 200mm +, you'll absolutely want a lens with a collar.

Awesome gadget, attached to my 200-400mm f4 and TC20EIII we were seeing Jupiter and at least four of its moons. Amazing!!!
