Well a little few minutes later I came to realize that aperture wouldn't let me change the setting. It says "00" on the LCD panel and display screen. So I started troubleshoting. Well noticed more things. I switched to AF on the lens but the camera would still display MF. I switched to photo mode and my camera would not take pictures. When I did try it would take like 20 seconds and the shutter would make a disturbing sound and I get a "Err 01 Communications between the camrea and lens is faulty. Cleans the lens contacts".&nbsp;</P><P>&nbsp;</P><P>This problem started happening about three weeks ago and since then every now and then the functions would start working properly soon after turning camera on or after shooting for a while but later go back to the errors.</P><P>&nbsp;</P><P>What I have done:</P><P>I cleans the ring mount and the contact points multiple time and still nothing changed</P><P>I have tried over 5 other lenses from differnt brands and also different mounts like EF and EF-S and still nothing changed</P><P>&nbsp;</P><P>I have a Canon 70D</P><P>&nbsp;</P><P>Someone please help otherwise I know the camera store will charge me a arm and a leg when I feel like it something simple that I can fix.</P> Thu, 20 Jul 2017 13:10:50 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70D-Lens-and-Camera-isn-t-corresponding-with-each-other/m-p/214474#M39070 Lloyd_D 2017-07-20T13:10:50Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/70D-Lens-and-Camera-isn-t-corresponding-with-each-other/m-p/214498#M39071 <P>Is it within warranty?</P><P>&nbsp;</P><P>The only user thing you can do is clean the contacts, and as you know that rarely works.
