I have a rebel t6. Yesterday I used it take pictures in manual and portrait mode outside. It worked fine. An hour later I went to take pictures with the same lense without changing any settings and it wouldn’t take a picture. It will take a picture in MF but it doesn’t focus. It will take a picture if the lens is remove and only the cap is attached. It will take a picture with my other lens. It won’t take a picture with my 18-55 mm lens inside or outside. It won’t take a picture in AF setting. It won’t take a picture using either the viewfinder or the LCD. It won’t take a picture outside on the green A+ setting. I have taken out the memory card and battery for 5 minutes. Nothing changed. I have switched back and forth between AF and MF. Any suggestions? Thanks.
ake a look at the post by Canon Product Expert Jesse in this thread.
He describes how to resolve a very specific problem related to the AF motors in the lens being jammed. If you remove the lens from the camera, and you hear a faint rattle when you shake it, then it is likely that you have this problem.
