I purchased this lens fromon the internet about 15 months ago. This lens has started to give me some problems. After I take a photo I get a message on my camera's screen that "Communications between lens and camera is faulty. Clean contacts on lens." I then need to turn the camera off and on again to reset. The photo is OK but this error message happens abiut 70% of the time. I have cleaned the contacts on the lens but the problem still happens. There are no problems with my other lenses. My camera is a Canon 50D.
Has anybody had this problem before?
I presume the lens is out of its 12 months warranty so is there a reputable repairer for Tamron Lens in Sydney?
