How to get my Angenieux 90mm f/1.8 mounted on my Nikon D7000 to focus to Infinity?

I have an Angenieux 90mm f/1.8 that I have mounted to my Nikon D7000 with an adapter but it will not focus to infinity. If I move the lens further from the sensor with another adapter will that help the lens to focus to infinity? I would love to use this lens for some video projects.

Using lenses that are not specifically designed for the camera body in question may or may not work properly… Apparently yours doesn't. Most of us regulars here will always recommend Nikon lenses for Nikon cameras because they are specifically designed for Nikon bodies.

If it doesn't work then it simply doesn't work. I'd suggest you shop for a similar size Nikon lens for this fine camera.

Not focussing to infinity is a symptom that's unavoidable with some adapters

Some combinations just aren't meant to be. Each different camera system has it's own mount, and the distance from the mount to the sensor/film is varies. Your Angenieux 90mm is from a system where the lens is mounted closer to the sensor than your Nikon F-mount camera. So this leaves you with a problem, as it's impossible to engineer an adapter than actually allows a lens to sit physically within your camera.

You have therefore three options for getting infinity:

1) Adapter with optic. You may not find such an adapter (depends on what lens you're mounting). These adapters also often will compromise on image quality, and act as a slight teleconverter.

2) Conversion. This lens was made in various different mount forms, for rangefinders and SLRs, and I've seen ones for Leica M, Exakta, M42 and most crucially Nikon-F. This means this lens can be converted to fit entirely externally from the camera, with no protrusions. However conversions are difficult and expensive jobs to do with varying results (depending on the quality of the engineer taking on the conversion)

3) Buying the same lens but for Nikon F-mount. They are available, I can't see any visible signs of adaption or conversion.

I'm not sure how old this thread is but I'm facing the same problem. I was wondering if Owen could answer the question about his working focusing distance using the adapter he has without focusing to infinity. I have a Nikon D750 and a Angenieux 90mm 1.8. I recently purchased a fotodiox adapter to use these two together. The adapter has two glass elements inside and corrects the focusing issue of not being able to focus to infinity. The only issue I'm having is that using this combination, the photos are completely useless when using the lens wide open. The pictures are soft and out of focus! Stopping down to 2.8 corrects this issue, and seems to get better by 4 and 5.6. There's slight vignetting through all the stops. I'm just wondering if I did use this adapter, what would my working focusing be. Would I be limited to using this lens as a good portrait lens only?
