Canon 85mm F 1.8 in Telegraph Cove, British Columbia for sale

This lens has been giving me an error (Error 01 - communication between the lens and camera) *once in a while* but since I shoot weddings I cannot take the chance of using it. It happens maybe 1% of the time I click the shutter so would be perfectly fine for someone who shoots portraits, nature, etc and does not rely on this lens to perform at a critical moment. It will often not give me an error for a wedding or two, where I use it quite often, then will do it maybe once or twice. The fix is taking the lens off and putting it back on and it fixes the issue.
I have just had it cleaned and the repair place advised if it happens again it is hard for them to know what the problem is unless it happens at the shop. Since having it cleaned it happened once. I just bought a new lens because as mentioned I cannot take the chance.
