R5 and Sigma lens compatibility

[Tammy K]

Hi friends!
I've got two questions.

1) Has anyone else had issues with the Sigma 35mm ART f1.4 not working with their R5? It worked great with my 6D and then briefly worked with my R5. But, started having a target ring that showed up in the viewfinder/lcd and pictures. It immediately had that same issue when I purchased a second R5. I just finally pulled the trigger on the Sigma lens dock. It's the only Sigma lens I have and I don't even know if updating the lens will fix the problem, so I dragged my feet on that purchase for about 3 years. Now, that I'm seriously contemplating buying either a 50mm or 35mm, I figured I should bite the bullet. Did updates fix this problem for anyone else? Did you have to continually update the lens for it to work with your R5?

2) Because of that apparent compatibility issue, I've refused to buy anything but Canon lenses since that problem began. I really want to buy a longer lens, ideally zoom for my kids' soccer games. Dang, those fields have gotten big as my kiddos grow! I've loved my 70-200 f2.8 for 10 years now, but it's just not cutting it. Since it's EF and I'm already using an adapter, an extender probably won't work great. Should I be concerned about compatibility issues between a Sigma or Tamron long lens with my R5 and EF to RF adaptor. I've been upgrading to RF lenses, but the long lens will mostly be for personal use and I just cannot justify the expense.

Feel free to recommend your favorite sports lenses! I'm wanting at least 400mm and probably no less than f4.5. Ideally, I'll keep it under $2k.

Thank you!

For now disable lens corrections in the camera (and you might have to in software). Your firmware update may correct this.

Some of the 3rd party EF lenses work pretty well on the R-Series bodies. However the 3rd party EF tele-zooms tend to have autofocus issues (like pulsing). I'd avoid them, esp for shooting action.

Consider the RF 100-400, EF 100-400ii, RF 200-800, or RF 100-500.

IMO the RF lenses with small maximum apertures still perform extremely well. Shoot RAW and process with excellent noise reduction (I like DxO PhotoLab).

Happy shooting!

That depends on the software. You can't expect Canon's DPP4 to have lens corrections for any third lenses, but any other decent RAW converter should have a set of corrections for most modern lenses released more than a couple of months ago.

All third party EF lenses were reverse engineered, some better than others. Sigma got it near enough right after 2016. The concentric circles are caused by Sigma not originally having the right in camera peripheral illumination corrections for the lens (switch in camera lens corrections off and they disappear).

Thank you both so much! I've searched that problem several times, but it's been a few years. So silly that one simple change in the 100s of menu options fixed it. Now, I'm wishing I hadn't bothered to buy the Sigma dock. I guess I can just ship it right back!

These are the ones I've been contemplating, thank you! Now that I don't need to replace my Sigma 35mm, i can justify pulling the trigger on my long lens.

The weirdest thing: with all my EF Sigma lenses (70-200, 100-400, 28, 40, 50, 85, 105) I can leave these corrections on, actually getting these corrections as well. If I remember it well the 35mm is the oldest Art prime, so that could be a reason this lens is an exception to the rule.

Do you have the Sigma dock? Do you get much use out of that?

Yes, I have it. I needed it to disable MF override in the lenses to get my IBIS properly working (no logic here, it's just true).

And I just found out that you can update your 35mm so you can leave in camera corrections on.

Oh awesome, thank you so much!

I was suddenly having focus issues with my 70-200 tonight. I only changed the first setting under the lens corrections in camera, so I'm not sure if that is the cause or not. But, a large number of my shots with the 70-200 had what appeared to be motion blur at far more than sufficient shutter speeds. My RF28-70 and EF135 were on point. I have had this problem before with this lens and was told it was an issue with image stabilization. I should probably make a separate post about this, but you seem super knowledgeable and any feedback would be greatly appreciated!

Image attached.
ISO640
f2.8
1/3200s

Several shot at f4.0 and 1/800s with similar blur, but I shoot at 2.8 all the time using eye detection AF with near 100% focus nailed. I'm guessing close to 1/3 of the pictures I took with my 70-200 tonight missed.

No sorry, I'm not. I don't know a lot about the Canon 70-200mm f/2.8 mkII adapted to an RF camera.

and any feedback would be greatly appreciated!

Maybe you should try and switch off stabilization at these shutter speeds, and see if that solves the problem.
