While the new 24-70mm f/4L IS isn’t as sharp as the 2.8 when you pixel peep, in real world applications (i.e, web and common print sizes) you aren’t going to see the difference. I do think you’ll see the difference between the new 24-70mm f/4L over the 24-105mm f/4L, so if sharpness and the best IS performance are important then it’s The Sigma is heavier hand uses a bigger filter, but to my eyes the difference in output between a Sigma and a Canon L is pretty damned minimal, with the substantial cost saving being the deciding factor for me. I have Sigma's 18 - 35, 24-70 Art, 50 1.4 Art and an a slightly older 70-200 2.8. Sigma lenses are universally heavier than everybody So far my results of comparing my Canon EF 24-70mm f/2.8L II to my new GM 24-70 has yielded similar results. The lenses seem to render in a similar way. Yes with the new lens I get EYE-AF with AF-C which is nice but I hear someone say that in some cases facial recognition is more important and I do get that with the adapted Canon. Last year for a variety of reasons, I ended up mostly using the 24-70 2.8 lens, mostly at 24 mm. It was pretty good. I don't remember what my assessment of the corners was, and I am using a new computer so I can't easily get to the images, but it was good enough that I kept using it on several trips. Nikon has the Z 24-70mm f2.8 S for 1800 EUR / 2000 USD (after rebates). It got a Highly Recommended in my Nikon Z 24-70mm f2.8 S review.

The second-generation 24-70mm F2.8 E-mount lens from Sony brings an all new optical design and focusing mechanism for improved image quality and focusing performance, as well as other new and improved features. The 24-105 L is shown above mounted on a Canon EOS 5D Mark II. I am sure that many Canon EF 24-70mm f/2.8L Lens owners will also have a 24-105mm L in their kit.

The RF 24-70mm f/2.8L IS weighs 1.98 lb, 900 g, with a whopping 82mm filter diameter and dimensions of 3.48 x 4.95" / 88.5 x 125.7 mm. The balance on the EOS R5 is okay but mostly because there is so much volume to hold onto and it is front-heavy.
