Folks,


Want to highlight and share a problem with this lens to all. I encountered last week that my 24-105 throwing out error 99 on my 350D. At times, it will throw out Error 01. The aperture show on the camera will be 00. The viewfinder will be darken (like pressing the DOF button). Some strange sound will be coming out from the lens for a short while. You can't do much except reboot the camera. Initially, everything went back to normal but it will be short live. Now, I can't use the lens any more except on 24mm. If zoom beyond 24mm, error 99 or error 01 will throw out.


Another friend of mine having this issue about the same time. His lens is about 1.5 year old. Mine is about 2.5 years old (UU series). He has send to Canon to repair. It was due to a faulty aperture module. Repair cost is about USD110.


Wondering is that a common problem or a bad batch of the lens ? Also anyone else in the flickr community faces this problem ?



I found a link which describe the same problem....
