FotodioxLens Mount Adapter - Nikon Nikkor F Mount D/SLR Lens to Micro Four Thirds (MFT, M4/3) Mount Mirrorless Camera Body, (10NKM43P)

This is easily the best $35 I've spent on camera stuff in a long time. I have a large collection of older Nikon lenses, and this adapter makes it possible to use some of my old favorites on my Olympus E-PL2.There are a couple of caveats you should know about:1.) There is no auto-focus when using this adapter, so it works best with lenses that have a decent amount of "feel" to the focus ring. Some later-model Nikon AF lenses have very loose focusing mechanisms (so that they present less resistance to the in-body focusing motor) but they can be twitchy when used as manual focus lenses.2.) You must stop the lens down to the desired aperture before shooting. This may darken the image in the viewfinder / LCD screen. This is necessary to get an accurate exposure reading, since the camera has no idea what the lens' maximum aperture is, and it has no way to set the aperture, anyway. Those of us who grew up with old-school Pentax and early Nikon cameras know this as "stop down metering". I used the camera in "P" mode -- I set the aperture, and the camera adjusted the exposure accordingly. You can tweak the exposure using the +- adjustment just as you would a normal Oly lens.3.) No operation with "G" lenses or AF-S lenses. Sorry, but this is just a mounting adapter, and it makes no attempt to connect the camera's electronics to the lens electronics.Caveats aside, I tried this with a few of my favorite Nikon lenses and was thrilled with the results, including the 50 mm f/1.4 AF, 60 mm f/2.8 AF, and 85 mm f/1.8 AF. All three produced sharp images with excellent detail, even at the corners. Since the Nikon lenses were designed to cover a full-frame (24 x 36 mm) 35mm film frame, the Olympus is only using the center of the lens - the part with the best performance and least distortion.Without the AF, I wouldn't try this setup for shooting an NBA game - but it would be fine for posed subjects, studio shots, and slow-moving wildlife work.I did not encounter any issues attaching or removing the adapter from any of my lenses.

This is an inexpensive adapter that allows you to mate a dumb (non-electronic) Nikon/Nikkor lens with a micro four thirds (MFT, M4/3) lens mount.I am using two of these adapters with 20 - 30 year old Nikon glass and a new Panasonic AF100 HD video camera. I am very pleased with the ease of mounting both the lenses to the adapter and the adapter to the camera body.I have used cheap adapters in the past to connect Nikon lenses to cameras such as the Canon 7D and Canon 5DmkII. These MFT adapters are vastly superior, as I do not feel that I am about to break them in half. When adapting my lenses to the Canon mounts I purchased an adapter for every lens because excessive connection/disconnection would quickly destroy the adapter. These particular adapters are much sturdier and more well made. While I purchased two of them, I now see that I could have gotten by with only one. However, at such an excellent low price it is prudent to have a spare in reserve for critical shooting.BOTTOM LINE: I am very pleased. Unless you have newer Nikon glass that requires an intelligent interface, I do not see why you would choose a more expensive option than this.

There is not much that previous reviewers have missed, but I'll put in my opinion anyway - it may help solidify the star rating numbers.Note that I use the optional electronic view finder on my E-PL1 and all comments are based on the photos being taken through that view finder. I have not used the adapter with the view screen built into the camera body.Having read the reviews below I was already aware that releasing the lens from the adapter requires sliding the release button backwards towards the adapter, not downwards, so I've had no issues with releasing the lens from the adapter or the adapter from my Olympus E-PL1.However, mounted on the camera there is a very small amount of play between the adapter and the camera body. I may have gotten an example that is at the extreme range of quality control for fit. The amount of play is extremely small and does not seem to affect the photos, but I've reduced the ranking from five to four stars; even an inexpensive adapter should be a snug fit. Not enough of an issue to return the gadget, or to recommend others not to buy.(As an aside, the Panasonic 20mm 1.7 with its metal mount is VERY snug on the E-PL1 body, while the "kit" lenses having plastic mounts go on smoothly and not as snugly as the Panasonic).Using a Nikon 50mm 1.8 and a Tamron 90mm 2.8 with the adapter has been a treat; as noted in earlier reviews there is no anti-shake or auto-focus; using in aperture priority appears to be spot on for exposure levels. The magnification button (for focusing) on the camera body worked with both lenses. (A second aside - the aperture control ring on the Nikon "nifty fifty" is nowhere near as good a "feel" as the ring on the Tamron. Also the manual focusing on the Tamron is a better, more solid feel to it. Of course the Tamron costs quite a bit more than the $125 Nikon lens).(A third aside - a split screen focusing aid is missed; my first SLR was an Olympus Pen FT purchased in 1969 and the feel of the E-PL1 with the manual focus lenses is somewhat reminiscent of that camera. A split focus screen would enhance focusing - and those old memories for me).The adapter is relatively inexpensive, and pretty much works as advertised. Recommended for those who already own such Nikon mount lenses (remember, the lens must have an aperture ring, there's no electronic connection to the camera at all).EDIT: I should have noted, there is no lens bag that comes with the adapter - the owner is on his/her own for providing storage. The device comes in a plastic bag inside a cardboard box. As noted in earlier reviews, there are no instructions either. You get the box, the bag, and the adapter.
