ownership:I used to own this lens
compared to:AF 100-300 F4.5-5.6 APO
price paid:Ł300 (used)
positive:nice range
rich colours
smooth focus and zoom rings
pleasant bokeh
negative:for better sharpness necessary to stop down
the build quality is not that impressive - my outer barrel (the zooming one) is quite loose and is wobbling
comment:best results when stopped down, optimal at F11.0, for 400mm even F16.0

my copy actually shows the minimal aperture numbers 4.5-6.3 as follows (it says on the barrel 4.5-6.7, but my 5D displays the minimal aperture no. as F6.3!):
F4.5 100-125mm
F5.0 125-140mm
F5.6 140-190mm
F6.3 190-400mm

the sharpness is best at the focal lengths between 150-300mm

if you do not need that long end 400mm, the 100-300mm APO is a better choice IMHO, is smaller, lighter and a bit faster

in general I do not regret I have bought this lens, even I have some reservations - I had an option to go with this one or Sigma 135-400mm, but I liked Minolta much more :-)

just do not expect the image quality, sharpness and the build quality of G lenses and you will be happy with this telephoto zoom lens
