Hi everyone, first sad post here. Here's my quick story.
I bought a 24-105mm lens from Craigslist yesterday. I paid 650$ for it. The price seemed really low, but it's not unusual to see deals popping from time to time here. I contacted the guys and had a meet-up.
By talking with him, he seemed to know nothing about photography. We were outside and it was snowing. I wanted to make this fast. He showed me the lens and I mounted on my 60D. Took a picture at 24mm, F4. AF was perfect, same for IS. Picture was sharp. I took a second picture, 24mm at F8. Again, everything was perfect. Took a last picture at 105mm, F4. Same as before, the picture was perfect.
I than expected the lens and it was in fairly great condition. Some minor dust outside and 2-3 particles inside. Nothing major. I than bought it.
Once home, I hurried to try it more. Upon using it, I got ERR 01. I cleaned the contact and tried again, still the same. I than came here, searched and found those topics : 1 and 2
I tried my lens back. At 24mm, all works perfectly. As soon as you zoom, you can't use it expect at F4. I have the same problem as them. I searched more and found LOT and LOT of people with the same issue. See here
Here is a video of the faulty lens in action : http://www.youtube.com …0&feature=player_embedded
And here is a whole topic with people who have had the same problem : http://cinema5d.com/viewtopic.php?f=11&t=16372
I still can't believe Canon hasn't acknowledged the problem. It seem to be a pretty common design flaw. So I guess my only option is to send it to Canon to get a repair quote. In the end, it will probably cost me more than if I had bought it brand new
So here it is, I'm stuck with a dead 24-105. If this post can help at least one person in not doing the same mistake, I'd be happy.
A pretty sad user, Rivest.
