EOS 7D Error code 01 when using EF 24-105mm lens

gabe54432 — Fri, 14 Jun 2024 17:53:44 GMT

I recently acquired a Canon EOS 7D and two lenses, an EF 24-105mm f/4L IS II USM and an EF 50mm f/1.8 II. When I try to use the EF 24-105mm f/4L IS II USM, it constantly gives me error code 01, that the contacts on the lens need to be cleaned, even right after I cleaned them. What should I do?

If you got it new from an authorised dealer, call Canon Support. They will walk you through a test and if necessary, arrange for a warranty repair.

If not, contact the seller.

Yeah, that almost never, to never, works or helps. You do need to call Canon 1 (800) 652-2666. The first thing they will tell you to do is clean the contacts! It is a feel good thing with them I think.

"...arrange for a warranty repair."

That's not likely since the 7D is over 10 years old now. I doubt any new ones are left on a store's shelf. But ya never know, doesn't hurt to ask.

Don't forget. Many used camera equipment dealers offer up to180 day warranties on used gear.

[EDIT] I find the combination of camera a lenses to be just a little odd. A 6D would make more sense.

I went through the same thing for years with Verizon and later Frontier when I had a landline. The service would fail regularly due to a farmer hitting a pedestal, mice chewing on wires in a pedestal, or just plain failure from lack of maintenance but they always started with: "have you plugged in a phone at the network interface box". I always jumped through that hoop but the problem was ALWAYS on their side of the network.

The contacts are self wiping on the lens/body interface so it is rare that cleaning will help but I am sure it has helped in a small number of cases.

A little odd, maybe, but not a lot odd. When I bought my second 7D, I chose the 24-105 II as the kit lens, because I was hoping to go FF eventually. It wasn't the ideal focal length for a 7D, but I got some really good pictures with it. And now I still think it's the best outdoor walkaround lens on my 5D3 and 5D4.

No, I think that combo of body and two lenses is more than just a little odd. It's almost like someone pulled model numbers out of hat. Granted, it is useful combination for a lot of photo pursuits. It could do a decent job at taking outdoor portraits.

But, it is a ten year old camera paired with two full frame lenses. One lens is fairly new, and I cannot be certain which version of the 50mm is being referenced. It is the 24-105mm that is out of place. It is the age of the lens, not the range of focal lengths, especially when paired with a 50mm prime.

BTW, is that a typo, or did you really buy the original version of the 24-105?

Sounds like someone sold their bookends.

Yeah, I think you're right. I believe the II was the recent one that, last I looked, cost only $100 more than its predecessor (presumably because most didn't think it was much of an improvement). The one I bought was the one that was current in the waning days of the 7D and was being offered as a kit lens for it.

"I got them together for next to nothing"

Good for you. They are fine and will work very well for you. I am glad I didn't have anybody give me advice like that or put notions in my head. I had two 7D's and I used the ef 24-70mm f2.8 for years. They made me a lot of money, too! The 7D is a wonderful camera.

I didn't have the 50mm f1.8 but I do have the ef 50mm f1.2L and I love it too. No matter what camera and/or lens you have somebody will always try to tell you, you can't do this or that with it. Or it isn't a good choice and, yeah, that isn't the greatest choice but it is very good and will do a great job for you. In the end it is you that makes it work.

What about the lens error? It does not sound like the gear is fully functional. Something is not right in there, somewhere. It should probably be returned!

"It should probably be returned!"

Diffidently choice. As is a repair because the gear is very good and it seems the price was right. I would at least inquire about fixing it.

So, which piece needs to be repaired? I would bypass that headache and simply return it, if that is still possible.

"... it seems the price was right."

You don't know this. Suppose he got it free? It is silly to just make a "its broken so return it". You don't know the territory. There are several options. Exploring repair is one.

The lens is defective and should have been recalled. That is why Canon quickly developed the second version of the lens. I've owned the one you have for ten years, EF 24-105mm f/4L IS USM. I've had that same communication error at least four times requiring the power diaphragm and mounted circuit board be replaced. I've spent almost as much money repairing the lens as the lens cost me. I would suggest you save yourself years of headache and get rid of that lens. Repair with a third party repairman and sell it. Get the EF 24-105mm f/4L IS ii USM, instead, or some other lens. Even a third party equivalent will be better for you over time than that lens. Again, Canon should have recalled the EF 24-105mm f/4L IS USM because it is an inherently defective product.

You know you are advising a person that posted his query 4 years ago. I am sure the issue has been solved one way or another in the past 4 years.
