Hi, yes, everything is up to date. I wonder why a 90D DSLR is able to drive the autofocus of the Sigma 500 f4 slightly faster than a brand new mirrorless R5. But you are right, situation is pretty ...

Hi everyone, Sorry for resurrecting this old thread from last year, which has been more or less solved with the latest firmware update. After using again my Sigma 500 f4 lens with my old 90D (which ...

Thanks! It looks like no prime super telephoto benefits from IBIS + optical IS...

Hi, I was very surprised to read that the brand new Canon RF 400mm f2.8 does NOT have coordinated control IS between IBIS and optical IS, here: ...

I'm not sure it's what they are talking about in the video: as you say that's only for JPEG shooters and is a feature recovering automatically dark shadows. Not useful for me: shooting RAW only.

Thanks! This is also how I'm handling exposure at the moment, but I was wondering if there wasn't a hidden feature in my R5 that could improve my results. Not having to raise exposure compensation ...

In this video (14:10), it's mentioned R5/R6 have an advanced metering mode that prioritize the focus area, picking up the best exposure regardless of the background (like snow). Any more infos on ...

I just made a few shots inside my home with my Sigma 500 f4, 1/30s hand-hold (R5 with IBIS engaged): it works for me. It's totally different if I use the 1.4 TC, or - I imagine - if I was using an ...

I personally choose my  shutter speed based on the animal movement speed more than my own stability. My R5 defaults to 1/500s: I raise this value when the light is low, and lower it when the ...

I love mine too, but since I have never tried any other prime 500/600 lens, I cannot say how better the IS/VR could be. Any comparison on this subject?

I'm using it with a Canon R5, after using for some time on a 90D, and I'm more than happy with the combo. I get images with great IQ, even when using the 1.4TC for birds.

I don't have a lot of other telephoto comparisons, the only one I tried in the Sigma 150-600C which I have sold now. I'm very happy with my R5/Sigma 500/f4 combo, yes. I'm sure (I know) there are ...

I notice the same thing between my 90D and R5 unless I enable the "dynamic" stabilisation mode on my Sigma 500 f4, thanks to their dock. With that, I have the feeling there is a slight improvement ...

Do you have the download URL? Could not find an updated manual for firmware 1.4.0.

Did you test this combo with the latest Sigma 500 f/4 firmware update? It adresses autofocus speed on the R5/6 bodies. It has been released on the 8th of July, so it's really recent: ...

I totally agree! In my case, I have somehow seen an improvement in stabilisation between my Sigma 500 / 90D and Sigma 500 / R5 (crop mode), but it's not huge. With Sigma's so called "Dynamic ...

With a Canon R5/6, you don't have the choice in fact: when a stabilized is connected to the body, the configuration menu that allows you to configure IBIS disappears. The only thing you can do is ...

I've got a Sigma 70-200 DG OS HSM for a while, and I'm more than happy with the image quality. I've been using it for the past year on a 90D with the standard image stabilization, without any problem.

Thanks for these tests: does a faster CFExpress card affect the viewfinder experience when shooting in HS+? Is it smoother with a CFExpress card? Personally, I don't care having to wait a few ...
