Hi, I am hoping that someone will be able to help. I have taken up photography again using my Canon EOS1000D, after a long hiatus. The last few weeks it has been working as one would expect; however, when I went to take a photo yesterday, nothing happened. After some fiddling, I found that the manual modes work fine, but when I try to focus in auto mode, nothing happens, though there is a slight noise from the lens. My zoom lens allows me to take a photo, but again without any auto-focus. I have tried to clean the metallic pin/connection, this has not had any effect. Has anyone encountered this issue, or do you know what might be the cause? Thanks in advance.
