Looking for Answers about Nikon Inc. AF Nikkor 50mm f/1.4D?

Fully functional but as with all lenses on DSLR's the aperture is controlled from the camera not the lens.

No.Coolpix L810 is a point and shoot camera. The lens on the L810 cannot be remove. This lens is for Nikon DSLR cameras.

Yes. The D80 has a built in focusing motor.

If you want to use this lens on a D3000 you will have to achieve focus manually since the camera body doesn’t have the internal motor for AF.

Nikon offers two types of autofocus digital camera bodies: those with a built-in focus drive motor and those which require a lens to have a motor. Cameras such as the D40 do not have a focus motor in it so they require the lens to have the focusing motor – an “AF-S” lens. While these bodies can use a lens with no focus motor (an “AF” lens) you would have to manually turn the focus ring to bring the subject in to sharp focus.

You may want to try the AF-S version of this lens.

The focal length in FX and DX is 50mm.

The 50mm 1.8 was just released that lens in my opinion is terrible.

Will not auto focus

Yes, when used correctly it produces a very nice bokeh.

The Minimum Focus Distance is 1.5ft.

No, it will be manual focus only.

Of course! All Nikkor lenses from the passed 3 decades at least are compatible with Nikon cameras!

Cameras such as the D7000 do have a focus motor in it. This lens will work on with your camera.

Yes, this lens is compatible with the D7000.

There is a 3-position switch located on the front of the body below the lens release button. This switch is labeled M-S-C. Turn it to "M" for manual focus.

No, this lens does not have an internal (aka AF-S) AF motor. It will NOT auto focus with entry-level bodies, i.e. D3000, D3100, D5000, D40, D40x, etc.

I had the same problem when i got this lens with my D7000 as well. What you do is notice the the writing on the lens, and the attachment white mark on ur camera, all you have to do is put the writing on the side of that white mark and twist your lens to the right where the writing on your lens stand on top when the lens is click in, do this a few time you will be good at this. This lens is a bit confusing as it does not have the white mark for attachment on it, and in the manual there is no where telling u how to do it.

You have 90 days of warranty for refurbished cameras and lenses.

no
