Seriously overpriced compared to the Sony and sigma offering.

Agreed the Sony 200-600 is $700 cheaper and just as sharp if not sharper.

I'm not a Canon nor Sony user, but good that you can compare lens sharpness on a 1080p video. Amazing!

No - just compared on Flickr. You can view images on much higher resolution photos.

Who's done a head to head with similar megapixel bodies, taking the same exact photos?

The Sony 100-400, 200-600 and the sigma 100-400 are all much better priced, and in the case of the Sony ones, much better lenses as well. Seems to be a trend with RF lenses..

Sony lenses aren't proving to be nearly as sharp as Canon and Nikon's mirrorless glass...

That's just not true. E-mount has some of the sharpest ff lenses ever made, while the latest RF offering has been average at best. A cheapo tamron 70-180 2.8 is way sharper than that fancy, overpriced RF 70-200 for example. E-mount also has the cheapest and most complete lineup of all milc systems by far.

I just sold my Sony A7RIII and Sony 100-400 and now have the R6 and RF 100-500 - I take mostly surf photos and so far have not seen any difference in photo quality between the two - I am not sure I would agree with you that the Canon 100-500 is "average" compared to the Sony 100-400?? The Canon RF 100-500 is a superb lens.

At least in my experience both Canon and Sony take equally great photos. I am finding the RF lenses easily match the photo quality of the Sony FF glass I had before.

Why did I moved to Canon?? it was for the better ergonomics of the Canon camera over the Sony body.

You paid more, lost a whole lot of light, and have to make due with a much worse sensor. All that to avoid a vertical grip?!
Anyway, we were talking about the lens, not the cameras.

Dude - why you being so grumpy?
BTW, you should learn how to spell correctly - its "do" not "due"

RF 100-500 is barely sharper than the EF 100-400 II, it's much more expensive than the Sony 200-600, and has a worse aperture, this lens is a joke.

Disappointed.

That lens looks like a wrist-wrecking behemoth. Speaking as someone with a wrecked wrist. I just gave away all my Canon equipment and am ready to start again with lightweight mirrorless equipment. (My brother-in-law is a photographer that never made the transition to digital. Maybe now he will). I haven't decided exactly what to buy yet, but obviously not Canon. Leaning toward Sony.
