ERR 01 lens not communicating

Post by argorob »

I have a Canon 70D with a 100mm 2.8 USM Macro lens (not the L). I can program the tube fine. I have sent the following in the utility program: Aperture 8, direction to camera and infinity, tried different stops 20, 30 and 40 plus I have tried suppress focus on and off. Tried camera in live view and eyepiece, put camera in aperture and manual mode. I also tried putting lens in AF and MF. I still get Err 01 lens not communicating please clean contacts. I did try my canon L 70 200mm lens once to test and selected that option that was built in the utility program and I got that one to work. Any guidance since I wanted to use the Macro 100mm primarily with the tube?

Thnx,
Robert
