Hi C Hing,

Appreciated if any one can enlightened me. I 'm using Canon 450D, Len was using Sigma 18-270. But the display kept on showing Err01, so i have to switch off the camera several times then it will back to normal.

After taking several pcs of photo, display kept on showing Err01. I not sure it is camera or lens problem???? Please help!!!!!
