Hi DVXUsers, :Drogar-Happy(DBG):

I know many of you are still searching a perfect Nikon to M43 adapter. But either they are cheap low quality Chinese made, or the Good ones that are 10 times more expensive. IMO, the real problem with most of the Cheap chinese adapters is the loosyness of the Lens Mount. When we try to focus or zoom, we feel little play in the Lens Mount.

Anyways, Some days ago while surfing ebay, I found 1 or 2 sellers selling this new FOTGA adapter which looked little different than the other cheap adapters on ebay, although this one was cheap too. I felt like giving it a try, and bought it right away for $27. Received it 2 days ago, I tested it. I tried it with my NIKKOR 85mm f1.8 and Tamron 17-50mm f2.8 lens on GH2. Here's the Short Review of FOTGA Nikon to M43 adapter.

First of all, I am very positive about the Mount. It holds lens Perfectly, feels just like how the FD Lenses fit on Ciecio7's adapter. Even more, it holds lens so tight that you can't even easily remove the adapter from the lens. On the camera mount, this adapter fits Perfectly without any play or jerk but not as tight as the Lens mount. On both ends, you can hear the pop sound to make sure the you have mounted it (on Lens & Camera) successfully.

Lens Aperture of any Nikon mount lens (Even Nikon G Lens) can be easily and smoothly controlled by the Aperture Control Ring of Adapter. The Gear which controls the Lens Aperture works fine and we can control it pretty fast in any situation.

UPDATED:
This Adapter has major problem too. If you use any zoom lens, be careful it change the focus while zooming. For more info, see this post.

On the Whole, newly available FOTGA Nikon to M43 adapter is a Decent Product for Fixed Lenses but not good for Zoom. If you don't have budget to tryout big names like Novoflex, give this one a try.

Hope this Review Helps. :) Feel free to add reviews of Adapters you tried.

at that price it's definitely worth givign a try. The little play in those other adapters sometimes ruin good takes, or require stabilizing in post.
 
Look, any Nikon adapter can be made to work, even the cheapos. The trick is to take a small screwdriver to the 3 leaf springs on the adapter. Open 'em a bit and your lens will fit tight. If you're only using them on the M4/3 body just buy enough so you don't have to remove them.

Too bad it has the redundant "Lock" ring, do you know if they make a plain vanilla model for non-G Nikon lenses?
 
Don't know if this company makes any plain adapters since their website fotga.com looks blank. But there are many such products available on ebay. Check this out from Metabones:220865282356 on ebay.

Whooooaaaa... dude is right!

My first Nikon F adapter was a Kipon, which was loose as hell on the lens side. I pried open the leaf springs, and, Voila, it helps! Still not perfect (insert a lens in there a few times and the springs will take a set) but it makes my Kipon useable.

THANKS!
 
I am new to the Nikon mounts, can someone confirm or deny that this Nikon adaptor with aperture ring, would work with lenses like this Tamron with no aperture ring? http://bit.ly/yHuZ6O Mount type is AF. I guess I am still just a little confused about mount G, AF, F. Thanks for this post, any info on this would be much appreciated.
 
Nikon G mount has NO manual aperture ring, so you need to use a Nikon G mount adapter to adjust the aperture of the lens.
 
From the perspective of using Nikon lenses on the GH-2, there are only Nikon lenses with manual aperture rings and newer Nikon lenses with NO manual aperture ring. The Nikon G mount adapter can handle everything, but I like the construction of the FOTGA F mount adapter so I would probably buy both adapters at these super low prices. ( My Voightlander Nikon F mount adapter cost $200 )
 
Nikon G is Nikon Brand that has no aperture control on lens. Tamron also has same kind of G lenses but it says AF lenses. The lens I used for this adapter is also Tamron AF 17-50 f2.8 has no aperture control on lens.
 
Adapter's Problem with Zoom Lens!!!

Adapter's Problem with Zoom Lens!!!

After playing more and more with this FOTGA adapter, I just found a very Serious Problem that I have never seen before in any adapter. :shocked: I am shocked, I should have figured this out before, but I played mostly with 85mm f1.8 fixed lens, I just didn't try much of a zoom lens before writing the Review and that's where the problem was.

I found that it is very critical to use it with any zoom lens if you want to zoom in for a Video. The lens shifts Focus with Zoom!! For example, I set the Focus to Infinity on my Tamron 17-50 lens at wide end, now when I zoom in to 50mm, the Focus surprisingly shifts back to 1 feet. When I zoom out back to wide, focus again shifts back to infinity. That's really odd!!? Infinity to 1 feet?!!

I never have experienced such behavior from an adapter. I tried to figure out what is the problem with this adapter. I checked the flange focal distance, i.e. I measured it's size, and finally got the Problem. It's 1mm shorter than my other adapter. That's it. I never thought flange distance would make such big difference. It's shocking that how the makers of this adapter gone blind with it. :Drogar-Sick(DBG):

This sounds like a lens problem ( i.e. Your lens is NOT parfocal, and thus will change focus as you zoom ), which is very common amongst SLR lenses, where only a very small number of lenses are parfocal. The Nikon 17-55mm f/2.8 is supposed to be parfocal.

I thought the same, but no, this is not a lens problem, my Tamron 17-50mm f2.8 XR works fine (Parfocal) on my another adapter.

The FOTGA adapter very likely does not provide infinity focus that is exactly sync'd to the infinity mark on your lens, correct?

You only get parfocal behavior from a parfocal lens at a particular lens-flange to sensor distance. Change that distance, and you lose the parfocal behavior, too. I checked this both with my own FOTGA adapter that is about 1.5mm too short and also with the lens on an extension tube, which goes in the other direction of flange-to-sensor distance change, but shows the same principle at work.
