20 Most Recent Sigma AF 70-300mm f/4.0-5.6 DL Macro Super Lens for Canon-EOS Questions & Answers

cleaning the contacts did nothing for me. what ended up fixing it was turning the camera to AV mode and setting to the highest f value. (f22) and then taking a picture. after that i was able to change it to what ever and resume as normal. hoping i dont see that error again.

cleaning the contacts on lens and camera is about all you can do. If its faulty and still under warranty then you'll need to send it back to where you got it from, any attempt to fix it yourself will void the warranty.

had this lens for my Pentax and used it for more than 10 years without trouble. Have you got the lock on? should be a little button on the side. Has it been dropped, maybe damage to the threads inside. If its still under warranty then take it to the place you bought it from with all its paper work and get it checked out.

Simply clean your camera lens contacts

Good luck and regards

If the lens is compatible with your Canon, the only thing I can think of is a defective chip or a bad connection inside the lens. just bring it back to the shop you bought it.

In the camera menu select 'Quality' RAW will be he highest resolution then Large jpeg, Med jpeg going down to the lowest which is S. Your camera my show the quality in Mps size the highest no. will be the highest resolution

The error 99 on your Canon is the last thing the camera can think of, if it really does not know what is wrong. If you don't have the message when using a different lens, and the error keeps coming back with that lens, you are right it is in the lens. But again the camera can;t find out what. The only thing you can do is make sure the contacts are clean and shiny and nothing os blocking free movement of all the parts on the lens. If you can't get it working correct, please contact a Certified Sigma service centre.

It will not focus on anything closer than 5 feet.

(From Sigma lens literature) Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.

Hi If the canon a digital one if so the sigma 70-300 may be to old and not compatible only if the sigma 70-300 is a super can it be rechiped will need to be sent to sigma

What kind of error? Err 99? You mention DS 126151, that's the model number. This camera is mostly know as Canon EOS Rebel XTi? Also known as the EOS 400D or EOS Kiss Digital X. If you are getting a Err 99 while shooting, try any other lens that will fit on your Canon. In most cases the aperture will become defect in these lenses. Not worth repairing if you ask me. One thing you could do, is shoot only at its maximum aperture. So that'll be F4.0 at 70mm and F5.6 at 300mm. That might work, but that might not be suitable in every situation.

Sigma makes their lenses with a variety of camera mounts. If you get the lens with a Canon mount then yes, it will fit any EOS Rebel camera body. A lens with a Pentax mount, for example, will not fit a Canon camera.

check your card,change with new cf.That might fix problem i had the same issue and it was my card.

Sigma makes their lenses with a variety of mounts. If the lens has a Canon or M42 mount then there is no problem. If it has a Minolta mount, for example, then replacing the lens will be easier and just as cheap as changing the mount. If it has Nikon mount, you can buy adapters to fit it to Canon or M42 bodies.

Sigma makes lenses with a variety of mounts. As long as you get one with a Canon mount it will work on your 600D. A lens with, say, a Sony mount, will not work on a Canon camera.

Yes. Bear in mind that many Canon digital SLRs have a sensor smaller than a frame of 35mm film. This results in the image being cropped, narrowing the field of view and making the lens behave as if it was of a longer focal length.

It will fit, but you cannot guarantee that it will be fully compatible.

Third party lens manufacturers have to reverse engineer the patented technology of SLR manufacturers and then arrive at their own alternative and non-infringing solutions. As a result, their lenses are only ever guaranteed compatible with the SLR models available at the time they were manufactured, and if those cameras subsequently have firmware updates then all bets are off.

Sigma do offer an update service on many of their lenses, but it's not free and the lens has to go back to them for modifications.

The only lenses you can be sure of being compatible are the original Canon branded models.

You need to zoom past 200mm and then switch it to the macro setting. You will see a mark on the focus ring that you must put the ring past on coming out of macro

Hi I sent a email
