Sigma Popular Questions, Answers, Tips & Manuals

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

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

The speed sensor is either out of alignment or is faulty.

Sure you can. But if you need money, you can earn on any sport. You know about game Analytics? See sample results https://777score.co.uk/ any games and think. Believe me it works and helps to get a good benefit.

If it the distance is not changing either the problem is that the unit is not receiving a signal from the sensor - bad connection, sensor out of place, bad sensor, etc. If distance is working but mph is not then there's something wrong with the unit itself, and if still bad with a fresh battery it must be replaced.

The computer will automatically switch to Transport mode if the bike is transported with computer mounted. Pressing any button is supposed to take it out of that mode. If it does not do so the computer has some sort of problem or defect. Here's the link to the Sigma support page, where you can find manuals and a contact form to ask for help. http://www.sigmasport.com/en/service/faq/fahrrad-computer/wireless/wireless/bc1416sts I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

Your question makes no sense. The Sigma is a computer, has nothing to do with selecting a bike. I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

I don’t usually play with flash that isn’t built in- I prefer natural light, but...if this were me I would: A) take very fine sandpaper and very lightly go one time over all contacts for the flash and camera. B) I would also see if my button batteries in my camera needed changing. As I remember they have something to do with recognizing lenses and flash attachments. C) I would also make sure the batteries in the flash, although changed, were making proper contact with the battery terminals and might also lightly sand those as well since the flash is little used.

I have this lens on my Pentax K3 and have never had a problem with it. The sensor is in the camera body not the lens so look in your camera manual for how to clean that. There will be a command in the cameras menu, maybe in setup. If that is not enough then go into the menu and lock the mirror up and clean out manually with a cotton bud with a drop of alcohol, methylated spirits. Be very gentle doing this. Also clean the electrical contacts on lens mount, both lens and camera. Test the camera now. If it works then job done, if not then you have more serious problem and its time to take it to a camera repair tech.

-Nothing will last. Keep charging when it's low. Good luck Mai

Maybe it is in frozen/hanging state. If you changing the battery too quickly it could be still in it. 1) Try to remove battery and wait two minutes before inserting it back. 2) !Be sure that the new battery is really fresh! If it no help the device probably went to electronic heaven...

If you take it to pieces, you will end up with a (hopefully complete) kit of parts which you will have to pay a repairer to re-assemble for you. Your choice.
