I have gotten tons of traffic to my previous blog post about my experience with the Canon 24-105mm lens problem. Basically, if you get an Error 01 message on your camera and you’re shooting with a 24-105, it is the lens, not the camera. I now have two of these lenses that I travel with: one new one and the old one which has been serviced. It seems like there is no rhyme or reason to the failure, it happens spontaneously and without notice, leaving whoever is shooting with that lens stranded. Canon has been very responsive to all of my problems – their CPS program is top notch. But it is indeed irritating to be on location and have equipment failure. On the other hand, I’ve had my fair share of purely mechanical failures before the popularity of shooting digital. My Hasselblad has fallen apart more times than I care to think, but because it’s mechanical and the problem is usually due to normal wear and tear that a professional would bestow upon heavily used equipment. This issue with the Canon 24-105mm lens is vexing, but I haven’t been notified of a recall. If I am, I’ll be sure to post about it and if I get any insight from Canon as to why this problem seems so prevalent, I will share whatever information I can. All I can say is that if you are going to get the lens repaired, send the body in to a Canon Factory Service Center with it and have everything inspected and cleaned at the same time. If you are a serious pro shooter, apply for the CPS program. The technicians know their stuff and do a great job with repairs and cleaning. Happy Shooting!
