Nikon lens to xt2 camera adapter?

[bbestone]

Hello,

 

 Fairly new to interchangeable lenses  and a total novice in the arena of adapters for non-fuji x lenses.  I would like to buy a Zeiss 85mm zf nikon lens for my fuji xt2.  What adapter would be the best for this?

 

Thanks in advance

From interest, don't Fuji make an equivalent piece of glass?

To the best of my knowledge there are no adapters that allow any electrical communication between camera and lens. This means that focus is only possible in manual mode and the aperture can not be controlled by the camera. So when you set the aperture ring on the lens let's say to 8 the apertur actually will close to 8. On a Nikon camera the aperture would stay full open to give you a bright view finder until you press the shutter button. Then the camera would close the aperture, take the picture, and open the aperture.

 

The simplest adapters can not be used with Nikon G lenses as these do not have an aperture ring but need the camera to control the aperture. (Remember, no electrical communication.) However, even some very cheap adapters like the Quenox do have an aperture ring on the adapter. On my Novoflex adapter, not the cheapest adapter, I can preset the aperture on the lens. If I turn the aperture ring on the adapter to one side the aperture is full open. If I turn it to the other side it closes to the preset value. I guess other adapters work the same way. On the Novoflex the ring does not have any marks and no clicks. The Metabones adapter has marks labeled 1, 2, 3..

 

Normal adapters will not change the focal lens. You have to consider the crop of the APS-C sensor versus full frame. The 85 mm Zeiss will not give the typical portrait field of view but more of a mid range tele. On APS-C a 56.67 mm lens would be the portrait lens. A 85 mm lens gives the field of view like a 135 mm lens on full frame. (127.5 mm to be more precise.)

 

There are adapters which change the focal lens like the Metabones Speedbooster. It multiplies the focal lens with 0.71. Thus a 85 mm lens will behave like a 60mm lens on an APS-C camera which is very close to the field of view on a full frame. Additionally the aperure will be multiplied with the same factor. So it gives you about one stop more open. Yes, it becomes brighter! The speedbooster is much more expensive than adapters that do not change focal lens. Quenox is another speed booster with 0.72 reduction. Quenox is much cheaper but seems to be not as good as the Metabones but still good according to the internet. I believe there are other Chinese made ones.

 

My Novoflex works like it should and I have never read any complaints about Novoflex adapters. However, there are some complaints about some cheaper adapters that they were too tight or too lose and that people had to return them once or twice until they got one that was ok.

 

I have a Quenox macro extension ring, in fact they come as a pair with 10 and 16 mm. They work fine but have a little slackness which allows to twist the adapter against the camera and the lens against the adapter a little bit. This sometimes interrupts the electrical communication. Then I have to twist the lens a bit and it works. The slackness has no effect on the image quality. Note, this is a Fuji X camera to Fuji X lens adapter. So it is easy to provide electrical comunication as it does not need any translation between Fuji speak on one side and Nikon speak on the other side.

 

I hope this helps a bit.

 

Edit: Some typos corrected and some wordings are now hopefuly better to understand

There are special adapter for G lenses they control the aperture on the adapter itself.

 

As for adapters conttolling electrical apertures, like for some canon lenses, they also exist, but they are very expensive.

[Jürgen Heger]

Milandro, you are absolutely right. I forgot to mention that the adapters with aperture ring on the adapter, like my Novoflex or the Quenox also work with Nikon G lenses.

 

Do you know who makes the adapter with electrical aperture? I understand that they still havo no auto focus.

[milandro]

there are experimental adapters trying to do this with contax and Fuji, maybe one day someone would make one for NIKON

Kipon makes a very expensive adapter with separate electrics to control Canon EF lenses.

 

 

But for OP the Nikon g adapters should suffice
