Ok, I don’t really quite like superlatives, but this lens deserves them all.
Because it’s almost unbelievable and absolutely WONDERFUL!
The only flaw that I can think of it is that it’s not a Zeiss (and I love Zeiss colors more that the yellowish Canon ones).
Bokeh, sharpness, flare resistance, autofocus accuracy and speed they are all over the top.
The price is over the top too, at 1.200€ street.
But this is a lens that you will use forever…
