Have had the EF-S 17-85mm for 3/4 years and it is main do all jobbie, now have a, to me, bizarre problem with it.
In the studio it works absolutely fine, the moment I try to use it outdoors it simply does not communicate with the camers and get error message telling me the lens/camera are not communicating and should clean the lens contacts.
Done this, few times and still have the same problem, the thing works inside does not work outside, tried it on two D450 bodies and a D350 body and the issue persists.
Does anyone have any similar experience and or advice on what could possibly be going on here please? :shrug:
 
May be worth checking all the pins on the lens and see if one is sticking, I am assuming they work on the same principal as Nikkor lenses.

Never mind, it is an odd one for sure. From the symptoms almost certainly related to movement disturbing the connection.

Still you may get some Canon guys on who have come across the problem.
 
Hi Martyn
decided to try on a dedicated canon forum and overwhelmed with questions and suggestions and have come up with the most likely cause of the problem which I thought should let you know.
Having adjusted the aperture settings etc and now tried it in semi-dark out side it would appear that the light in to lens is the villain, or more precisely, one of the contacts for the aperture sender has gone awry, so must have un-wittingly given the lens a bash at some point in the very near past. Seems my only solution is a canon repair job. Fortunately am headed toward UK and should be there on Monday so can take it in myself.
Thanks for your suggest though.
