As always, you can find examples of images shot with a particular lens or lens+TC combo at flickr.

Even with an EF 2X III it does well enough in the right hands:

With EF 1.4X III:

There are a ton more by the same photog at the same event with the EF 1.4X III included in the search results here:

This photog's 'Sigma 120-300mm Sports' album has some pretty good stuff in it. He doesn't say what TCs he is using in the ones with the lens shown as 168-420 or 240-600, but when he uses a 2X Extender with a Canon lens it is reported as the EF 2X III in the EXIF info of those images:

hi guys
I had the 300mm 2.8 IS version 1 for a while and have the 2.8 non IS one from 1991 still in my possession, together with a new 400mm IS II.

just my personal pixel peeping experience, the 300mm non IS is sharper than the IS. I like the size of the old one for my small hand is easier to hold and the IS version 1 is a lot fatter on the body even a little lighter. build quality the old one has a more dense feel and buttons are made from copper not plastic.

last weekend I tested the 400 IS II with my 300 non IS on a 1ds Mark II and I can't tell the sharpness difference, I take the 300 non IS to the field more because it's lighter. but one thing I remember is extender worked a little better on the IS version 1, that is the 2x III, with that said I do get great results with the non IS as well, even at 600 5.6, go down to 6.3 improve a bit.

the 400 2.8 IS II take extenders well even at 800mm it's sharper than both lens at 600mm.
