I bought this 2x lens to give more zoom capability to my CoolPix 4300 camera. The 4300 only has a 3x optical zoom built into it, which I found is not really enough for taking action shots and that kind of thing. This lens doubles the optical zoom maximum to 6x. That helps a lot for pulling in the subject, but is definitely not like having a 400mm lens on an SLR, for example. For my camera, and I think most CoolPix cameras, you need a small screw-on ring adapter (Nikon UR-E4, for the 4300) to attach this lens to the camera. The adapter can be a little hard to find I discovered, as most photo places tend not to stock it. I did find one though. The lens itself is very well made, lightweight, and comes with a nice little velvet bag and lens caps for both ends. It takes great photos without any weird side effects or aberrations. I've found that it's best if you use it in well lighted situations, or use a tripod, to avoid blurring the subject as a result of camera shake.

I have a Nikon Coolpix 5000, and needed this lens to help out the 3x optical zoom it comes with. The lens has great optics. No distortion or aberations. It requires an adapter to use it with the camera. Screw on the adapter and the lens to the camera, tell the camera you are using the 2X lens and you are ready. Wish they had bayonet mounts like the SLRs.

...this is an incredibly sharp lens.

If you own one of the popular Coolpix cameras and want to increase your zoom potential, this should be yoru first choice. Not only are the optics first rate, but the lens is not overly heavy. This enables you to screw it on and walk aroudn with it. Photos produced with this lens are stunning and very crisp. The only drawback I'd say this has is the limit of only 2x telephoto/teleconverter aspect, but that is what keeps it relatively light! Amazon also sells a 3x version, but it is significantly heavier and it will end up in the closet instead of on your Coolpix.

Get this lens - you will be *thrilled* you did.
