as a very happy owner of the 300mkI, I'd mostly like to hear more from working pros about the noticeable differences in image quality & handling.. is the slight difference in sharpness really discernible in real world shots? is image quality & focusing speed with tele-converters improved noticeably? are there other subtle nuances in terms of small changes to the form factor/weight that improve handling the lens for longer events?
the MkI make of this lens is pretty much perfect (to me at least) already. so with the improved MTF charts, slightly lighter weight, added features of the mkII, i really have no doubts that it deserves to be called the "perfect" lens.
i would love a 4-stop IS, as i hand-hold quite a bit.. but outside of that, i remain unconvinced that i'd even notice much of a change in my work for the current $3000 price tag to upgrade (sell mk1 for $3800-4000, buy new for $7000 after taxes)
i have no doubts that the 300mkII is a sparkling lens & if money were no object I'd have one.. or 5
