Expected more but worth the money bought used.

  • Summary: Expected much more from this lens at wide open. I think I just got not a great copy. The more stopped down the sharper the image but it's consistently soft wide open.

Surprising Sharpness Considering Its Reputation

entropic-remnants, Ebay
7 March 2011
  • Summary: I bought this as an additional secret weapon for weddings and industrial hand held, low-light shooting. This is the latest version of this lens (there is an older version that is not "DG"). This lens is either loved or hated apparently due to the Sigma curse of poor quality control. I've been lucky with Sigma's so far, but I've had friends that had to send their lenses back. To Sigma's credit, they always seem to return a well adjusted and properly operating lens.

Awesome at f1.8

  • Summary: The lens does exactly what I'd hoped for, shooting environmental portraits where the subject is tack sharp and the wider view is out of focus but discernible. I had loved the shots I'd seen pros make with the Nikkor 24mm f1.4 at f1.4, but as an amateur can't justify $2k+ for a specialty lens. The Sigma 20mm f1.8 does nearly the same thing on my Nikon DX body when shot at f1.8.

  • Summary: If want a fast aperture f1.8, wide-angle 20mm, full frame sensor capable, prime lens--you have virtually no other options under $1,000. Quality build, a bit heavy with an unusual auto focus/manual focus mechanism. Feels good holding, easy to control and manually focus. Fast auto focus. OK sharpness wide open @ f1.8. Exceptional sharpness @ f4.0 and up. Low distortion and CA. Great bokeh! Get to know it's limitations and you can excel @ photo taking with this unique lens.

Surprisingly good for the price!

  • Summary: Very bright lens at this focal length. Surprisingly sharp, even though the edges lose some sharpness. So, it may not be the best lens for film or full-frame digital cameras, but with the crop factor of many digital SLR's, the edge sharpness in negligible. Still, given the price, this is an excellent lens for all formats. One thing that could be better is focusing speed. It's kind of slow, so I recommend manual focusing, especially in low light conditions.
