TS-E 17mm and Extender EF 1.4x not working on EOS R

[Sojora]

Hi everyone. I have a problem trying to used mi Ts-e 17mm lens on a Canon R body (not RP). I been used this lens for a long time on a Canon 6D without any problems but in the Canon R I have the "f00" error message. I already tried the Canon R adaptor with seteable ring, the Canon adaptor without ring and a drop in filter Meike adaptor. In all the cases to verify that it is not a problem with the adapter, I have used other lenses (canon 50mm, 85mm, extender 1.4 and tokina 16-28) and they work well on both cameras but the extender 1.4 or the ts17mm doesn't work. Can anyone help me? Thanks!

Your TS-E 17mm is not communicating with the [camera], which is why you are seeing “F00” for an aperture value on your cameras.  Your lens is in obvious need of service.

The third party RF-EF mount adapters are known sources of problems, which is probably why Canon forced those products off store shelves.  Owners of the third party products were blaming Canon for their gear not working or being damages.  Your lens may have fallen into the latter category.

I tried 2 Canon brand mount adapters, one simple, the other with a customizable ring, and one with a drop in filter Meike brand . I don't think that's the problem. Maybe its a lens issue like you say.

Stop using the Meike brand mount adapter.  It is one of those cheap, imported knock-offs that cause error messages and possibly even damage gear.

Like I said, Canon forced that gear off store shelves for good reason.  I suggest that you put it in a drawer somewhere, and then forget where you put it.

You must not be using a Canon brand tel-con. I don't think they will bolt up to any of Canon's T&S lenses. However,  that is something I have not nor would not ever do. "The third party RF-EF mount adapters are known sources of problems, ...", this is why most of us with decades of experience advise to not use off brand accessories.

Mostly batteries and grips but also true with te-cons.

Think again.  It’s a problem.  Your damaged lens speaks for itself.  Listen to it.

[EDIT] There have not been any public statements from Canon as for the exact motive for enforcing their copyright.  I can tell you this for certain.  These forums were being flooded with users complaining about their gear not working.

 In many cases, their new camera bodies were being damaged.  I suspect Canon may have found itself in a warranty repair crisis, which is probably something you may not want to talk about in public.

I'm sorry, but you talk as if the problem was all with the Meike mount adapter and it was the third option to test the lens on the Canon EOS R because the other adapters manufactured by Canon do not work. I understand what you are saying, I take the suggestion about the meike brand but I insist that that is not the problem.

There were a lot reports in this forum with camera problems when using 3rd Party mount adapts. They were relying on Canon to fix the problem. Canon did not make or design the 3rd Party mount adapter. So its NOT Canon's responsibility to make it work. This sounds like a communication problem with the lens. So no matter what adapter you use it will not work. I highly recommend using the Canon branded adapter(s). There was a reason Canon told 3rd Party manufacturers to stop manufacturing RF Mount accessories. People were blaming Canon for there camera problems. Its NOT a Canon problem but a 3rd Party manufacturer problem.

I think you insist too much on taking the conversation to another topic. I am saying that the Canon ts-e 17mm lens does not work on a Canon brand R body, using 2 different types of Canon brand mount adapters, made by Canon and your answer is still that the problem is the other manufacturers. I mentioned that after not having results with the Canon brand mount adapters, I tried (already tired of not having results) with a Meike brand adapter to see if I had another result and it still does not work. But your answer focuses only on the latter when clearly the problem occurs before using these other brands of adapters. However, I appreciate your response.

You have a lens communication problem not a mount adapter problem. TS-E lenses work on the EOS R series when adapted. On some cameras the camera will allow Manual Focus assist/ focus guide. To help manually focusing the lens since the lens doesn't have AF.
