My experience with it is mixed. It has good performance throughout
the field of view on my 1.6 crop body. It is sharp, but suffers from
lower contrast than the Sigma 30/1.4 which it is inevitably compared to
for crop body usage. The Sigma's center sharpness is better at f/1.4
than the Canon's at f/2.
The focus is accurate with either lens, but some have reported copy
variation with respect to Sigma autofocus performance.
My copy of the Sigma focuses great, but it is softer on the right side
of the image than the left, and the Sigma is known from asymmetrical
sharpness issues from copy to copy. Still, the Sigma has certain
look that I really like, and when you nail the focus on your subject
at f/1.4 it really has an incredibly pleasing look. Some complain of
the Sigma's bokeh, which is admittedly unusual. It's fine to me, though.
The Canon is a solid performer, but I feel it is an old design in need
of an update, and that it performs well but not great in any single area.
Stop it down a little, and it is more than adequate in sharpness. The
color and contrast performance has never been exciting to me, but
that's partly because I keep comparing it to the Sigma, which despite its
significant issues and limitations, has a certain Pop to the image that
the Canon never gives me.
This is the Canon, wide open:
