Very smooth bokeh
Loose focus ring
|comment:||I have a love/hate relationship with this lens.|
For all large aperture shots with good center sharpness and very smooth bokeh, this lens cannot be beaten on this focal length. Stopped down, center sharpness only improves. I use cropped shots as fake-macro shots, it can be that good.
Build quality is also very good, as can be expected of the Sigma EX-series lenses. Only thing I noticed after about 6-8 months of use is that the focus ring loosens and wobbles more and more over time. As I MF all the time, this is a bit of a letdown.
As a landscape shooter, the biggest negative is the corner softness. Even stopped down, the corners are not as sharp as I expect from these kind of lenses.
Only thing I really don't understand is how hard it can be to design a hood that can actually be attached in one go?! Most of the time, I leave it off.
I don’t know about QC at Sigma, because I just own one copy of this lens. Maybe other copies are sharper in the corners, but from what I’ve read in several reviews, I doubt it.
