20 Most Recent Sigma 75-300mm f/4-5.6 DL Lens for Nikon AI Questions & Answers

The problem you are encountering is with the screw head interface between the lens and the camera body. They just are not locking together properly. Sounds like you need to send her in for repair.

Assuming the lens has a Nikon mount, yes.

Sigma makes lenses for a variety of cameras. Different manufacturers use different lens mounts, and they are not interoperable. A lens with a Canon mount will not fit onto a Nikon body, for example.

Yes and no. The lens will fit on the D5000 without a problem. But the sensor on the D5000 is smaller than a frame of 35mm film so you'll end up using only the center portion of the image. What this amounts to is that the lens will act like a 115-450 zoom would on the N5005. Also, if the lens doesn't have a focus motor built in (Sigma calls it HSM) then it won't autofocus on the D5000. You can still focus manually, though.

Yes. The D300 has a focus motor built into the body and thus does not need one in the lens. The lens will also meter properly with the D300.

If the lens has a Nikon mount (as you imply in the post), then no, it will not fit. If it has a Canon mount, then yes, it will work fine on your Canon Rebel.

Unless you want to start a career in camera repair- find a repairman or send it to Sigma- as a repairman with almost 40 years experience, I wouldn't even work on your lens- leave it to the people who built it- sorry

Hi If it works on a dynax minolta it shoud work on sony digital cameras

Best option is to go to photogrphic shop with the camera and lens and ask for converter that will fit on both ( if available ).

Every lens made after 1996 with AF is made for that particular body. Hence the reason many small camera stores when bust, carrying a huge inventory for the 6 or 8 different cameras out there.

First, is the lens older than about five/six years old? If so then the electronics are almost certainly incompatible.

Error 99 is a generic code to say the camera isn't communicating with the lens. The first thing to try is thoroughly cleaning the contacts on the lens mounting flange, whilst doing so clean the contacts on the camera body as well. Don't use anything metallic to do this with.

If this fails then you either have a faulty lens or simply an incompatible one. By turning the lens slightly as if you're removing it, you can ensure that the contacts don't align correctly and then may be able to use the lens fully manually. Focus the old fashioned way and if there's an aperture ring you can set it to what you require: the viewfinder display may not show the correct exposure but will expose correctly when you press the shutter. It's a real bodge though and not something you'll be happy doing for very long.

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

Hey kgconstruct,
The lens description that your posting is categorized under is a 75-300 f/4-506 DL lens for Nikon AI. If this is correct then no this lens won't work on a Canon camera. I am assuming this isn't correct and the lens you have is for a Canon camera, and if this is true this lens should work on the XTI. If you’re thinking of buying this lens I would go to a local camera store that carries this Sigma lens and try it out first to make sure you like it. I hope this helps!

Sincerely,
Allan

It is not normal for the focus ring to move slightly when using autofocus mode on the Sigma 70-200mm f2.8 APO EX lens. This could be caused by a problem with the lens or with the camera body. One thing you can try is to check if the lens mount on the camera is clean and free from debris, as this can cause the lens to move when the camera's autofocus system is trying to adjust the focus. You should also check if your lens firmware is updated to the latest version and make sure your camera firmware is also up to date.

You can't do this yourself. It needs to be carried out by professionals and is a 'clean room' with service techs in full dust proof protective wear. Send it to them. https://www.sigma-global.com/en/support/ ..

Question edited for clarity. You get the Sigma lens for the camera in Canon fit. https://www.google.com/search?q=sigma+lens+af+75-300+for+canon+rebel+xti Can you use Sigma lenses on Canon cameras? Since Sigma lenses are made to be fully compatible with Canon cameras, they are backwards-compatible. This means that you can use a Sigma lens on a Canon DSLR camera. Similarly, the Sigma cameras are backwards-compatible with Canon lenses. Macro adapter loses the AF feature. https://www.google.com/search?q=sigma+lens+af+75-300+mount+adapter+ring+for+canon+rebel+xti

Taking it apart is not the problem - re-assembling it will be. Unless you have access to an optical laboratory, where laser instruments can measure the exact tolerances required, don't even think about it. You will be left with a pile of optical components, and a far higher repair bill than if you had just let the experts sort out the problem in the first place.

Best you don't open it at all as you can damage the lens. Send back to manufacture
