Canon 35mm prime

Hi all...I have had this lens for a couple of years. Ever since I got it I receive a lot of camera errors saying that the connection between camera and lens is poor/ not connected...please clean contacts...something like that.

Always meant to get it looked at or exchanged...the horse has bolted on the exchange.

Anyone have any home remedies for this kind of thing?

I mean it works...just seems to lose connection with the camera often enough to make me want to smash it into the nearest brick wall I can find.

Thanks

Do you mean the 35mm f/1.4L prime? If yes, check to see whether the body is bent, even a tiny bit. I had such a bend occur when the lens was mounted to camera to the camera body in a camera bag, then later mishandled as airline baggage. I no longer ever allow mounted lenses in a camera bag. The 35mm f/1.4L apparently can easily become misaligned with sufficient side pressure on the barrel of the lens.

Best of luck OP!

It's not the L. Just seems like the metal connections don't engage well...it 'fits' perfectly onto the camera but the digital kind of information gold coloured metal musn't link / engage with the camera body properly. Camera tells me to clean it. I'll have to get back to this thread later with more accurate details

OK, the other 35mm then, got it.

If it really is the contacts that are in some way tarnished, you can clean them nicely with an eraser.

Just do the cleaning with the lens at a slight angle so that eraser chad falls down/out, not into the lens.

Eraser? Like a school kid rubber at the end of a pencil?

No, just get a q-tip and some rubbing alcohol and wipe the contacts. Make sure you don't leave any q-tip lint behind and see if that fixes you up.

Ok man thanks

I got the error message with a cheap Hong Kong battery all the time, no matter what lens.
Sometimes it comes when changing lenses while the camera is powered on.
"ON-OFF -trick" makes it go away.
