Third party lens compatibility on the Nikon Z and Canon EOS R cameras has been a hot topic for many of those looking to switch. Neither Nikon nor Canon exactly have a wide range of lenses for their respective systems yet. And while Tamron has been scurrying to release firmware updates, Sigma has been ploughing through their entire catalogue to check compatibility.

Sigma has now announced and updated list for Canon EOS R compatibility with quite a few more of their EF mount lenses, adapted to fit on the EOS R. There are one or two caveats with some lenses, but I think that for the most part, those Canon/Sigma shooters looking to add an EOS R to their arsenal can probably rest easy.

When SIGMA’s interchangeable lenses in the current product lineup, listed below, are used in combination with the Canon “EOS R” and their “Mount Adapter EF-EOS R” or “Control Ring Mount Adapter EF-EOS R”, both AF and AE operate without any issues. Furthermore, lenses which incorporate Optical Stabilizer (OS) will work with the OS function properly in effect.

Sigma splits up the compatibility chart into two lists. DG and DC lenses. Sigma’s DG lenses are the full frame models, while DC denotes 1.6x crop APS-C lenses. Using one of their DC lenses with the Canon EF-EOS R adapter does not automatically put the camera into 1.6x crop mode, though, so you’ll have to enable that manually.

DG Lenses

DC Lenses

* Camera’s “Scene Intelligent Auto mode” cannot be used.

Three particular lenses do exhibit some slight quirks, which Sigma also mentions in their new list.

SIGMA 24-70mm F2.8 DG OS HSM | Art

  • It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.
  • It may stop the focus driving from infinity to closer focus distance while shooting video with AF.

SIGMA 60-600mm F4.5-6.3 DG OS HSM | Sports

  • It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.

SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary

  • It may require the battery to be taken out once, if restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.
  • It may stop the focus driving from infinity to closer focus distance while shooting video with AF.

Most of Sigma’s discontinued lenses haven’t been fully tested, for obvious reasons. So, your mileage will vary with those, depending on when the product was released and which version firmware the lens is running (and these old lenses will need to be sent to Sigma for firmware updates – assuming an update is even available – as they don’t work with the dock). But the lists above should offer plenty to keep you going for a while.

    I am a Sigma 150-600mm F5-6.3 DG OS HSM Contemporary user, without any problem, I have it updated to the latest firmware, specifically to “2.01”. I have always used it with a Canon Eos 5D Mark III, recently I have acquired the new Canon Eos R Full frame without a mirror. I have seen the recommendations of use with the new Eos R, but still when I have used it, with the AF function “AI SERVO” and I am tracking object and shooting, the objective focuses very well, but when shooting the object, In the camera’s electronic viewfinder there is a delay (such as an image “Lag”) that causes you to lose track of the object you want to photograph in high-speed shooting. After looking at the instruction manual, the camera apparently has a function that improves high-speed vision, but when pressed on it, the camera message puts that function is not compatible with the Sigma lens.
    As usual, I have contacted the Canon technical service, and after several messages, the last thing they answered me was the following:
    “With reference to your query on Servo AF focus failure when using your EOS R and a Sigma lens and a Tamron, it is likely that the fault is due to an incomplete compatibility of your Sigma and Tamron lenses with Canon systems, since The camera may not be calibrated for the Servo AF focus with this lens.
    Canon does not publish technical details of its technologies or share them with third-party brands. The way these firms design their products is through reverse engineering techniques on Canon products. It is therefore possible that there is no complete compatibility of your lens with your EOS camera, by introducing technological advances for which the accessory may not be designed, and the system may not be calibrated.
    When launching new products and improvements, Canon takes special care to ensure the compatibility of its products with previous generations of accessories but we cannot guarantee the compatibility of third-party products. It is up to the manufacturer of that accessory to ensure compatibility with the Canon product. I therefore suggest that you contact the manufacturer of the accessory. ”

    I just contacted Sigma to report this ruling, to see that they respond
