Hi Guys,
I'm a Canon man and don't know much about Nikon. I am interested in the Tokina 11-16/2.8 and Tamron 60/2 and I wonder if the Nikon version come with aperture ring on the lens. If so, I will be able to mount them on a MFT body (I'm eying the OM-D) and work in manual mode.

A quick google image search shows these lenses have no aperture ring, but there are many nikon MF lenses that will adapt to m4/3 mount. I hadn't heard of the OM-D rumor/leak. Very nice. Can't wait to see pricing/reviews.

I have already searched before posting and found pictures without aperture ring. However, as I am not familiar with third party lenses for Nikon I thought it is possible that people who actually used this lenses may offer different data.
I also know that there are many old MF lenses with aperture ring (Nikon is only one of many which made them) but technically these lenses are peerless. This is why they interest me so much.

Yakim, don't forget that there are m/43 adapters for Nikon G lenses (the ones without aperture ring). These adapters work with both old and new Nikon lenses.

Much obliged. Indeed I forgot. Thanks for reminding me.

The disadvantage if these G-converters is that you can't set a real value for the aperture, but have to guess for the value.

With the ring on the adapter you can open en close the aperture, but there are no values(2.8 etc) visiable. Mine is limited to 2.8 too, so no bigger apertures than 2.8 possible on my shift-adapter it is possible to go to 1.4.

I can confirm that both the Chinese and German made G-series adaptors can work all the way to f/1.0 as in wide open, but the Chinese made is not very accurate and as well made.

At lease for the few Chinese made G-series adaptors that I had tried and used.
The one I bought was made by Pixco and if one compare the picture with a few other brands also made by the same manufacturer in Shenzhen will noticed that these adaptors have very rough operating aperture control rings, it feels as if the metal ring is grinding against the adaptor barrel.
The next thing is there is this free play when one twist the aperture ring that actually caused the lens and the adaptor to rotate about 0.5º to 1º with respect to the mounting ring. This will be critical if one requires precise focusing using lenses with very little DOF like the 50mm f/1.2. With a well damped focusing ring on the lens will make it difficult to focus because the adaptor mount is rotating at the same time the focusing ring is being rotated by the photographer.

I 've a F to MFT and a F to NEX adapter, both Chinese made, one is very poorly made, but the NEX one (from Kipon) is ok, good finishing, mount and turn smoothly, but it came with the mount installed upside down (but I can fix it myself).
It focus a tiny tiny bit beyond infinity but I really have no idea whether those expensive one (like Rayqual from Japan) guarantees stopping precisely at infinity.
BTY, I think all G lens, including 3rd party one, can focus past infinity themselves, but I have several MF lens so I do wish to get a good adapter that stop at infinity.
The aperture control ring can turn smoothly, but actually quite difficult to use since you can only guess what aperture you are using.
I can confirm that both the Chinese and German made G-series adaptors can work all the way to f/1.
Can you tell me the brand of the German made adapter? Thanks.

Zeiss makes lenses that still have the aperture ring, but are only manual focus. The older Zeiss lenses do not meter on a lot of cameras. For that you need the ZF2 lenses which are a couple of hundred dollars more.

Novoflex is the name of the german made adaptors. They are fairly expensive. About $ 269 or so for a leica to mft adaptor. I assume they make other adaptors though.

Dave, can you elaborate? I thought that metering is done TTL so it doesn't really matter which lens you mount and if electronics exist or not. At least in Canon it is so.
p.1 #18 · Do third party AF lenses come with aperture ring on the lens?
The metering cannot be done because there is no electrical communication between the lens and the camera. This is probably only confined to the lower Nikon models. As you get into the higher models, I believe you can program in the lens fl in mm and f/stop max. You probably have to use Aperture or Manual mode using the sperture ring for metering. Of course all the Zeiss lenses are manual focus except the Sony models for some reason. On Nikons metering is done wide open on the lens so ttl metering does not work at your chosen f/ stop.
I'm not 100% sure of this information. Maybe someone else out there knows for sure.
p.1 #19 · Do third party AF lenses come with aperture ring on the lens?
The metering is TTL, but the metering is performed wide open and the lens is stopped down just before exposure. So if the camera doesn't know what the aperture setting is, it won't be able to correctly meter. The higher end cameras have a tab that indexes with an AI (or later) lens with an aperture ring, thus communicating the aperture to the camera electronics (they will only work in A priority mode, until you get to AF or AI-P lenses where the camera can set the aperture automatically).
(but I can fix it myself).
