I have a tamron XR Di 2 SP 17-50 mm lens on a Canon 7d body. In the picture mode I get the error 01, faulty communication between lens and camera. In the movie mode everthing works normal. Any other lens (Sigma, Canon) works fine in picture mode. I cleant the contactpoints of lens and camera, I did several hard resets on the camera but the problem persists. Any sggestions? sincerely, Maarten

I get the same issue with that lens but on my new Canon 60D

Try cleaning the lens and camera contacts gently with a lint-free cloth

So, have you cleaned the contacts as you were advised? You do this by removing the lens and cleaning the contacts on the camera body and on the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

Welcome to Fixya
Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.
Thank you for using Fixya!

This is the kind of error which you always risk these days in buying lenses which are not from your camera manufacturer. Error 01 simply means that the camera cannot communicate with the lens. Canon's protocols are not open standards and third party manufacturers have to reverse engineer to produce something which works. As they're working in the dark, they cannot always arrive at a solution which makes all models suit all Canon bodies.

You have two possible solutions:-

Visually inspect the contacts on the lens and the camera body and if they're anything other than clean and bright then use a clean pencil eraser on them. Be very, very, careful not to let any of the rubber crumbs into the lens or the camera body.

If that fails, visit the Tamron website to see whether the lens can be returned to be updated for other bodies. if it can't then sell it and buy a later Tamron model or better still a Canon one. They may cost more, but the results are better and their resale value is much higher.

hi, clean the camera contacts also , change the firm ware of the lens , hope this helps

Error 01 means that communication between camera and lens is faulty. Try to clean lens contacts.

Nothing you can do. The Tamron is not compatable with your camera. So the focus will be slower

Your question is posted under a Nikon version of this lens. I assume you are talking about using the Canon EOS mount version.

The short answer is: Yes
