It looks really muddy. Is this adapter having glass in between or is it just hollow? I can't fanthom what could cause such a muddy 100% crop. it's not normal. What part of the picture was cropped, center, mid or corner?

That's why I also asked whether a tripod was used: look at the shutter speeds.

yes, something is wrong. Either some horrible glass is in between, or some problem with stabilization on the lens, or bad calibration of AF. But I see no shake direction. I really looks as if a mist of oil of a bad TC is in between. I also think the TC idea will not work out very well. There are some very cheap manual 300mm from Canon, maybe that's a better idea.
