Nikon to Canon adapter

[JamesMichael]

Hi all

I just got a metal adapter to fit my Nikon lenses to a 5D mark ii. When I put the 85mm 1.8 AF D lens on it, it works fine in Aperture priority (aperture ring set to F16), which is all I need except it reads that the lens goes to 1.4 That would be nice. Obviously a miscommunication. It is not such a big deal. Just curious what is going on.

Now, though, I have another issue. I put the adapter on to the Canon body then attached the Nikkor lens. When removing the lens, the adapter came with it and now I can't get the adapter off the lens. Is there some technique for removing adapters from lenses like this? I am beginning to think one should be more wary with cheap no name adapters but I lose control with cheap stuff.

Thanks a lot

Jamie

Just curious what is going on.

Setting ƒ16 will tell the camera and allow it to close
down to that… in other words it submits your lens to
the control of the camera.

ƒ1.4 is the largest aperture of Nikon lenses and you
can see the set aperture if you press and hold the
DoF button on the camera.

It all seem to work fine!

Does the adapter have a microchip on it? If not the f1.4 is what the camera defaults to when there is no exchange of information between the lens and camera, which is quite normal.

To release the adapter from the lens, there probably a sprung metal strip on the inside of the adapter, which acts like a ratchet when the lens is mounted and holds it in place. Release the sprung strip with a fingernail, knife blade or small screwdriver and you will be able to twist off the adapter.

Do you have any details of the the adapter itself or a link maybe? They come in various forms.

If it's like one I recently used for adapting F mount lenses M4/3, there is a spring loaded knob on the side. Slide that away from the lens (towards the camera) and turn the lens at the same time. Remembering of course that Nikon lenses turn the opposite way to Canon . You may find you need to use a fair amount of turning force to separate the lens from the adapter. Many of these adapters are made very cheaply and tolerances seem to be all over the place.
