Tokina 80-200 2.8 AT-X compatibility issue with Nikon D50
The lens works on manual setting, and erratically on some
autofocusssettings. I can sometimes get it to work by unmounting and
remounting.Is is just imcompatibly with my camera, or is there
something I'm notaware of? (I've had the lens for many years and used
it withoutproblems on my N8008S, so am disappointed it's not working
well on thenew D50.) Thanks. ps - I have a Nikon 35-70 AF which works fine on the D50.
I have one that had the same problem...it needs to be re-chipped to work with the newer camera's. It worked great on my N80 just not on my D-50...I got the F-- error when the exposure meter shut off. Send it to thk photo to be rechipped....takes about 3 - 4 weeks, gets cleaned and re-calibrated for about $83.

You need a Minolta to Canon adopter. Because the Tokina was made for the Minolta in the first place. Be aware that even with the adopter, there is a very great chance you always have to focus manually, because the lens can be fitted on the camera, but the electronics will not be compatible.
That is one of the things you almost aways lose, when using lenses from a different make.
Assuming you get one with a Nikon mount, yes. Sigma makes their lenses with a variety of mounts to fit different makes of cameras. A lens with a Canon mount, for example, will not fit on a Nikon. A lens with a Nikon mount is fully compatible with the D50.
ALL Nikon AFS branded lenses are compatible with the D3000. The AF lenses are usable in manual mode.
Sigma, Tokina and Tamron lenses without the built-in motor are manual mode as well.
To be sure, check the manufacturer;s websites.
Hope this helps,
Hi, Sorry to hear about your lens. If you are able to autofocus and take pictures with any other lens, then it means that your problem lies with the kit lens. If you can take picture in manual mode, but not in autofocus mode, then the AF motor in the lens in not functioning. I had the same thing happen to my 50mm 1.4 lens. Depending on your location, there are Nikon repair centers in Melville, NY and Torrance, CA. Hope this helps, Andrew
All lenses are optical: light comes in one end and goes out the other. There's no digital/non-digital about it.
What there is about lenses is the size of the image circle. Lenses cover a certain area. A lens that covers a 35mm film frame, such as the Sigma under discussion, will also cover a smaller area, such as the sensor on a D50. It's possible to design lenses with a smaller image circle. These smaller, lighter lenses are sometimes called "digital," because they are intended to only cover the typically smaller digital sensor. Using such a lens on a full-frame or film camera will produce dark corners. This is NOT an issue in your case.
Turn the aperture ring to the smallest aperture (largest f/number) and lock it there. Set the aperture and shutter speed on the camera body. You didn't specify which camera you're using, so I'm afraid I can't give you details there.
You will find all the information in the camera manual, not the lens manual.
This normally means that you have forgotten to set the lens aperture control to it's minimum aperture (the highest number). On the D100 the aperture control is via a wheel on the camera body instead of via the physical control on the lens aperture ring.
The error message you are getting means the aperture ring is not locked to the smallest aperture setting, and by this I don't mean set to the smallest aperture the lens must have the ability to be locked to the smallest aperture. It is unlikely that the problem is in the camera body. Some older lenses are just not fully compatible with the newer camera bodies, but if this is the case you should still be able to use the lens in manual and aperture priority mode but with limited capabilities. I hope this helps!
