You.
It is a bit soft but pretty good for that lens IMHO.
At 600mm you need a high shutter speed to avoid camera movement making the image soft...even if your focus is spot on.
The get high shutter speed (e.g. 1/2000 s for this lens) you need high ISO because the lens has a relatively high minimum f-stop (over 6?). The high ISO would make the image soft due to noise.
If the OP uploads using "store original" I'll take a shot at what Topaz can do for it.
