Sigma 18-35mm f/1.8 DC HSM Art

One of my best lens, even if clearly not the most expansive one. You can shoot at stars and get sharp stars everywhere, even in the far corners at f/1.8 (not exactly punctual, but very close to and better than whatever I saw before at such aperture). It is sharper than the Zeiss Distagon 25mm at f/2.8. I also realize that the contrast I get from pictures with this lens is larger than with all my other lenses. This clearly appears when I develop my picture in Lightroom v.3.6: the "black level" that is set by default at 5 (and is usually fine) must be set near zero. The focal length may seem too short for portraits, but I got great shots (I modestly think) with this Sigma 18-35 on my D300 (full-length portrait particularly). Indeed at full aperture, the DOF is only a few inches at one meter. For me the bokeh is quite nice, even if the light spots are a bit triangular in the corners.
