Quantaray 100-300mm Lens for Nikon

Contact Sigma, That's who made the lens for Quantaray,

The lens is a manual focus lens. It doesn't matter which mode you have the camera in, you'll still have to focus it yourself.

Yes, the lens is compatible with the D60, with one proviso. The D60 lacks an autofocus motor, relying on the lens to have one. This lens does not, so the autofocus feature will not work. Other than that, everything else will work.

Yes, assuming we're discussing SLR cameras. It can also be used with most Nikon film SLRs.

Yes, with caveats. The autofocus won't work on D40/D60/D3000/D5000. The metering may not work in all modes on all cameras. Since you didn't specify which camera, I can't give you a better answer than that.

I have 30-year-old Nikon lenses working fine on my D90, but without metering. And the old lenses date before the invention of autofocus.

I WENT TO B&H PHOTO AND GOT THE ANSWER FROM THEM.

Provided it's an autofocus lens and if you buy the D80, then yes, it will.
However you will have to use manual focus if you want to use that lens on a D40 or D60, because these bodies do not have built-in autofocus motors.

You can use it, but it will not autofocus on your D60. It will set exposure properly, but you will have to turn the focus ring.

That's good info. The trouble is that Quantaray makes lenses for different bodies. Your lens could be made for Minolta, Nikon, Canon or other. You may be able to find a universal adapter but first you need to know what mount that lens was originally made for. I recommend either taking the lens to a camera store or calling Quantaray to see if they can look up the mount using the serial number.

Turn the aperture ring on the lens to its smallest aperture (largest f/number) and lock it there if it has a lock. You control the aperture through the command dial on the camera body, not the aperture ring on the lens.
