And it won't be tack sharp on a 24mp APS-C sensor. It may be reasonably sharp.
Also - just to put this into the grand scheme of things - the Olympus 300mm f/4 - while more expensive - will eat those two RF lenses for lunch.
The effective output quality will be higher - and unlike these RF lenses, the Olympus can take full advantage of Dual-IS - while also being an equivalent stop faster.
Of course, the argument won't matter if you own an R camera. However, in this specific cases, the equivalence game fights back.
Out of curiosity, I looked up the price of the Olympus lens you mention. $2790. That is more than both the 600mm and 800mm lenses. Of course, the Olympus needs an 1.4x TC to compare to the 800mm lens. That adds $349, coming to $3129. So that now 840mm f11 lens will eat that Canon 800mm f11 lens for lunch? For a mere $2229 more? And of course it is not a stop faster than the Canon 800mm f11...
