75-200mm Sigma Lens Darkens

Every time I use my Sigma Lens on my Nikon D100, after taking a couple shots everything gets really dark and I can't see anything through the camera and it also takes really dark pictures. I don't know what's wrong with it. When I first got it, it worked fine up until a couple months ago.

Re: 75-200mm Sigma Lens Darkens

Hi the lens has a lock on the iris ring and on your  D100 it must be locked on the RED nuumber.

Sigma lens manuals

Chuck, sorry for the late response. Last days I had to work through several hundred anonymous questions. Most irrelevant and not complete, so I could not answer most of them, but I had to read them all.
Sigma, does not have a service, where you can download a manual. But the manuals from Nikon, most of the time don't tell anything about how to use the lens.
I found a page with all specs. The link is down here.

I have to guess why you did put the question here in the first place. I think because you have a Nikon camera without a focus motor. Like a D3x00 or the D5x00 or a D40 or D60. (for the x you can add 0 1 2 or 3)
If you have one of these camera's the lens can't be used with auto focus You only can use the lens in manual focus. Most other camera's from Nikon, like D80 D90 D7000 D300 and more expensive, all do have a focus motor and can work with this lens in full automatic focus mode.

Which lens fit nikon d5001

To the best of my knowledge, most, if not all, Sigma lenses fit most cameras that use interchangeable lenses with the appropriate adapter. As I recall, Sigma uses a bayonet mount and adapters are available for many name brand cameras. For example, I have a Nikon and my Sigma 600mm came with an adapter for a Canon. All I had to do was order a Nikon adapter. If you're not sure, you might want to check with a local camera store to confirm which adapter you need.

I recently bought a sigma 28-80 3.5-5.6 ii macro for my nikon d5300, the lens will not mount to the camera body. I noticed some plastic pieces had broken off the backs of lens. Have I purchased a defective...

Here are 3 pictures of a Sigma lens for Nikon. Your lens should look about the same. Could be a little less connection points, but notice there is no plastic.

Nikon d7000 keeps flashing fEE

This is with the Sigma 24mm? If this is with the Nikon 24mm AF-D or another lens with an aperture ring then turn the aperture ring to its smallest setting (largest f/number) and control the aperture from the camera body the same way as with a lens without an aperture ring.

If it really is with the Sigma lens, try cleaning the contacts on the back of the lens and in the lens mount on the camera body.

My husband has a Nikon F65 NON-digital camera for which he has an APO sigma 170-500mm lens. I am thinking of purchasing a digital camera for him (Nikon D50). Will this sigma lens be compatible? Are lenses...

Yes, the lens will be compatible with the D50.

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.

Darkened Images

Sounds as if your diaphragm may be sticking due to either the camera or the lens. Look at the back of the lens and work the small tab with the aperture ring set to f32 (or 22). See if the tab moves smoothly but with resistance from a spring, or if it sticks or moves roughly. If it does this with other lenses too, another possibility is the aperture lever on the camera. Mount the lens and set it for f22 or so and use your depth of field preview to see if the lens is stopping down smoothly. In either case it may need professional repair.

Sigma 170-500mm APO lens on Nikon D50 won't autofocus or shoot

When you get a flashing EE, it means there is an Eror somewhere. Most cameras have a botton you press to reset it. Usually it is the battery check button. Try that. Also try taking the lens off the camera, unlocking the aperture ring, remount the lens and then lock the aprture ring to the minimum F stop. I think this should solve the problem.
