I have the canon EOS R7 and canon 100-400mm lens. I was taking photos of burrowing owls - it was midday and very sunny, they were far away so it was at the end of the lenses range but the photos in their entirety (background + owl) were all coming out so strangely, I've never seen "focus" come out like this before. I'm trying to understand what is causing the softness - user error, and if so what exactly (settings, shake, etc), or something up with my lens or camera. I have a few other examples, all hand held on a bright sunny day. At 200mm I am seeing a very sharp image that I'm happy with (grackle). At 347mm (duck), not a sharp image, but not as terrible as the owls. Is this to be expected as I get closer to the end range of the end? I've cropped the photos a bit just so it's easier to see how they look. Would appreciate some insight, as this is driving me crazy!
Image details below:

I recently bought an EOS R7 and also having issues with sharpness with images I take. I am using a 18-150 IS STM kit lens and an RF 100-400 f5.6-7.1 IS USM lens. When I open my photo in "Preview" app and zoom in, nothing is clear. I am not getting the clarity and sharpness i would have expected. I am always having to sharpen in Topaz. Can you advise? I will include two photos, one using the kit lens and one using the zoom. please help.100-400
