Nice shot and sharpness, but the photo belongs in the "self portrait" section !
Anyway, seriously, i just got my 55-210 yesterday. (together with the 50mm)
It's a great lens though i've only just been able to get some quick garden shots (blame the bad weather).
But I can see that it is quite sharp (a lot better then for example the canon 55-250), even at the long end.
Can't wait to give a real spin, but waiting for sunny days...
