Question: Would this set work with Nikon D2x and AF Micro Nikkor 60 mm lens ?
Document: Kenko Auto Extension Tube Set DG 12mm, 20mm, and 36mm Tubes for Nikon AF Digital and Film Cameras - AEXRUBEDGCI have not used this much since purchase, but can see its advantages for macro work. I tried the 36mm tube with my 70-300 zoom VR lens. While the magnification was good, the VR lens was so heavy it made the whole camera "unit" unstable and the connection between camera and lens felt tenuous. If that lens had a lens mount for the tripod it would work fine.
If it matters to you, it says "Made in Japan" in a conspicious way. By the way, if you want to get into a macro photography with only about $10 investment, an adapter from Photodiox to mount a lens (such as a low-cost prime Nikon 50 mm F/1.8) in reverse and using manual focus, exposure and f-stop would work fine. You will get crisp pictures, but the field of view will be very narrow.
As far as I can tell these support MF, AF, AF-S lenses as well as the different aperture communication mechanisms of the Nikon F mount. So I can use them with my AI MF 55mm Micro-Nikkor, or my Sigma 180mm DG AF IF HSM Macro, or my 85mm AF-S G Micro-Nikkor.
I have been using these for work as a failure analysis photographer (basically industrial forensics) for a few weeks. They are hard to beat when it comes to getting the extra magnification I need. That said, they do have their flaws. If you stack all 3 tubes and use a heavy macro lens (I use the 105mm f2.8 micro AF-S VR Nikon at work) you will need to support the lens as well as the body.
After I got the micro tube. I first try to mount my vivitar manual focus lens on it. Unfortunately, it cannot be mounted. I was quiet disappointed and took my Nikon AF-S lens out to try to mount it. This time, it actually work pretty well. Focus is still fast (less than one second) though a little slower than directly mount to camera. I give this product 5 star because they are supposed only work on Nikon lens.
GOOD INVESTMENT . Cant believe how well they work by them selves or all together . THIS HELP'S TO BRING MACRO TO A NEW VISION . Must use lens over 100 mm  for best results . I'm very happy with this prices . I highly recmend this set :) AJV
No electronic failures or other problems noted.I also attached a heavy, fast, glass-laden Nikkor 35mm-70mm AF f/2.8D lens with all three rings. I set the lens to 70mm, hit autofocus, and the autofocus screw drive worked through all three rings (though it was sounding a bit taxed) and the camera was able to autofocus on a subject.
Unfortunately, these did not work at all with my Nikon D3100 AF camera. I was really looking forward to using them, as I had read some good reviews, but they did not make any electrical connection between my lenses and my camera, and as a result, my camera would not focus. Not a bargain at any price if it does not work.
I've taken some great pics with these but I do find them difficult to use - or maybe it's just me. The auto focus doesn't work with my lenses, which isn't necessarily a bad thing as manual focusing is more practical up close, anyway, but it should. I can't get focused on anything 5' away or more. Is that how it's supposed to be? I'm using a Nikon D200 with a 60mm micro lens.
After seeing several examples of images these tubes can aid in creating on Flickr, I ordered a set for use with my Nikon D90 & a 85mm f/1.4D AF lens. Simply Stunning!!! Dont buy a macro lens when you can get a set of tubes for a mere fraction of the cost. The tubes have no affect on metering or focusing at all. The results are highly professional.
Answer: I am not sure but I would be surprised if it didn't. It will not autofocus. I never use any "auto settings" so I don't know what works and what doesn't in terms of electronic features. They me closer focus and that's all I wanted. Based on my usage they are great.
