Sigma 150-600 Contemporary won't communicate properly with R5 and R6 since firmware upgrade

markphoto — Thu, 29 Sep 2022 19:48:57 GMT

I'm using the Sigma 150-600 Contemporary with an EF-R adapter on my R5 and R6. It worked fine, until I upgraded the camera firmware to the latest version. Since then, I get an Error 01, "Communications between the devices is faulty. Check the camera, lens, or mount adapter contacts".

I have tried cleaning all the contracts with isopropyl alcohol.

Has anybody encountered this problem? Will upgrading the lens firmware solve the problem? I would have to purchase the lens dock to do this.

I have been using the Sigma 150-600c lens for two years with both the R5 and R6 bodies with no issues whatsoever. However, I have always kept the Sigma firmware up to date - I strongly recommend that in its own right as there have been several improvements over time. The docking station is worth getting as you can really tweak the features of the lens to your needs.

If it were me, I'd contact Sigma to see if they are aware of the problem and have a solution.

I certainly think that it is worth a try. However, Sigma have consistently said that they did not design these lenses to work with the new R-series bodies, and that they do not guarantee the results.

Mark, given that the last firmware update I have is 1.6.0, and my system still works fine, I would suggest saving the camera's current configuration to one of the Custom settings (C1-C3) and then doing a camera reset to see if that resolves the issue. If not, you can then restore your camera back to the previous configuration.

I was told by Sigma there isn't any update to the firmware for the 150-600C. I had a dock on order and cancelled it. When I go to their support site, the latest firmware is Ver. 2.03, dated 2020.08.20 (well before I purchased the lens). I will have to get a dock to see if Sigma's Optimization Pro can do better than that.

Tried that. No help.

I'll try that.

Sorry, I'm a bit confused about the dock

You said: I had a dock on order and cancelled it. then... I will have to get a dock to see if Sigma's Optimization Pro can do better than that. Can you clarify please?

In looking at our parallel situations, I am trying to find something different between our setups. Can you advise what brand EF-RF adapter you are using please. I am using the Canon basic EF-RF adapters.

If your mount adapter is not made by Canon, then your odds of having issues using it are high.

"I have tried cleaning all the contracts with isopropyl alcohol."

Stop doing that, it very rarely to never helps and can make things worse. Much worse!

"I'd contact Sigma to see if they are aware of the problem and have a solution."

I would too. Canon does not make their cameras work with off brand lenses. It is up to the lens maker to make sure the lens works on a Canon body. I think this might be an ongoing problem as I have heard of it from several different people.

As to the Sigma dock, I would buy it, I did. It is of little use 99% of the time but when you need it, it is a nice to have unit. It isn't expensive. If it were much more expensive I would advise you don't need it. Sigma used to, they may still do so, update your lens FW for free. But you have to send the lens to them. A hassle, expense, for sure that the dock eliminates.

I’m using Canon’s EF-R Adapters, the ’plain’, basic one in my R6 and the Control Ring Adapter on the R5. Same problem with both.

Can you point me to somewhere that explains how to save your configuration to the Custom Settings and putting it back? It’s not something I’ve used before.

I’ve generally always used Canon’s lenses and accessories until I got the Sigma 150-600 and the 18-300 for my 80D. Which non-Canon adapters are recommended? They all seem to be brands I’ve never heard of, except for Neewer.

I recommend only Canon adapters, and they are the only ones that Canon supports - which does not imply they support third party lenses attached to them. So far, I have tested about 29 Canon lenses using their adapter and had no issue.

It's in the camera manual. That should be your first port of call for any questions about how to use the camera

“I recommend only Canon adapters, and they are the only ones that Canon supports - which does not imply they support third party lenses attached to them.”

Of course, I totally agree with that recommendation. Like I pointed out above, if you are using a third party mount adapter, then the odds are high that is the issue.

Actually my first response is an internet search. I have the manuals on my iPhone and iPad, but there are often more specific instructions online. Such as:

I read that the other way around somehow. I do use Canon adapters.

It’s not something I’ve used before. and Actually my first response is an internet search. I have the manuals on my iPhone and iPad, but there are often more specific instructions online.

In this case the manual clearly states how to save configuration settings, and I then wonder why you asked us to tell you where to look for the information instead of doing the search within the PDF's yourself.
