If you have a G mount lense, this Mount Adapters will allow you to use your lenses on the film/digital camera body. Sharing lenses has some distinct advantages. Certain prime lens just can't be replaced, and you save the cost of purchase on new lenses.
This Adorama lens mount adapter is made with high standard precision. The leaf spring design in the adaptor holds the lens tight to the camera body ensuring there is no play between the camera and the lens. It's all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences.
This lens mount adapter allows All Nikon lenses, including the Nikon G-type lens with out an aperture ring, to fit on micro 4/3 camera body and still maintain the full control of the aperture adjustment.
Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode. Infinity focusing is guaranteed.

the aperture control on this adapter does not click, it tries to keep the lenses open with some friction but not successfully I have to continously check if the aperture is wide open as it slowly closes
Purchased this item to use my collection of Nikon lenses on a newly purchased Panasonic G3. Overall it does what I wanted it to do, which is to be able to use my 50mm 1.4D (non-G)on the G3. The all metal adapter is sold, mounts and operates smoothly. Aperture control on the adapter turns smoothly as well, but there is quite a bit of grease on it that is visible around the ring. All of my lenses with an aperture ring works with the adapter. I could not get the 18-200 VR to mount, and I wasn't about to force anything. Was not planning on ever using it on the G3 anyway, so I didn't care much, but the description says that it works with G lenses. I don't have any others to test with, so I'm not sure if this incompatibility is the exception or not. I like using the aperture control on the adapter to quickly shift the lens from wide open to stopped down when focusing. Not sure if that was it's intended use, but it's a nice touch.
Love using this adapter with my old AI, AI-S lenses and AF-D on my Olympus E-PL1. Works very well with AF-S G lenses also. I can get more critical focus with this adapter than just the standard electronic range finder of the D200 or D5000. Nice and sturdy and I like the stiffness of the aperture ring. You won't be accidently turning this ring. The only problem I noticed was the lens release latch knob was loose and tightening it up forces the bottom of the knob against the adapter body. When you push the knob back the lens latch pin doesn't release forward into the lens. The latch pin is held captive in the adapter body. So if you're not careful the lens can rotate and fall off the adapter. The bolt shoulder needs to be about 1 to 1.5mm longer so it locks up against the lens latch pin. All in all I still think this N/G-4/3 adapter is the best bang for the buck.
