the autofocus is fast
Super fast and accurate auto focus

and improved
lens performing well on resolution charts is excellent in the field

lense really is not as heavy as it looks
400 DO as being large and heavy
missing is the focus preset feature
extra weight and a shorter focal length
sharpness of this lens is not in direct relation to its price
models having lower optical quality
No longer a new lens
the AF becomes less accurate and a bit slower
my budget was a bit tight
Autofocus may slow down just a little
lens flare and direct light contrast loss
usual row of function switches
IS USM is only marginally behind
lens is overpriced
Lens cap is ridiculous and useless
big
heavy
and expensive
color fringing did not rear its ugly head in field tests
