Bad focusing

Wah, Amazon
19 February 2014
  • Summary: Overall its a good lens. auto-focus is pretty crappy sometimes when you're trying to catch something fast. Loud autofocus when its on video mode, but manual focusing is pretty quiet and smooth. Pictures come out clear, get a good wide angle without distortion like a fish-eye lens.

Aurora Lens

Marvin W. Falk, Amazon

  • Summary: I purchased this lens to photograph the northern lights in Alaska. It works well for that purpose, but is not as sharp as my Canon EF 17-40 f4 in brighter light.

Nice lens for APS-C format cameras

Shinebox, Amazon
28 March 2013
  • Summary: This is for a Canon mount. All the other reviews pretty much sum up this lens. On APS-C it crops out the ugliness of the smeared corners. I can't get a sharp pic in any corner at any aperture on FF. On APS-C it's a different story. Just use f5.6 for everything and you will be ok.

Digital SLR Novice but I Love This Lens!

Patrick Callen, Amazon
6 July 2012
  • Summary: Huge Objective for Light Gathering! I Don't Manually Focus Very Often My Judgement is Not That Good with My Eyes Anymore. Sometimes Hunts A Long Time to Focus in Auto Mode! But That's Rare, Most of the Time... Fine! I Do a Lot of Close-Up and Sometimes Large Group Candids. Perfect Lens for This!

Good value for the money, especially for the DSLR videographer on a budget.

  • Summary: This is a solid lens. I would recommend it to new and ametuer consumers -- for the money, the picture is hard to beat. I use it primarily for video when I want a wider shot than my Canon 50mm f/1.8. The lens provides clear shots at wide angles.

Images come out soft while set at 1.8f

Cole Johnston, B&H Photo
24 May 2012
  • Excerpt: I use this lens for portraits, it is great for that. having the lens set at 1.8f is very difficult to make the image sharp. Very nice Bokeh. sometimes has slow focusing. all in all it is a nice lens and extremely durable.
  • Pros: Consistent Output, Durable, Nice Bokeh
  • Cons: Blurry Focus, Slow Focus

Decent lens at a decent price

Michael Solomon, B&H Photo
29 November 2011
  • Excerpt: Works great for video work on my Sony FS-100. Love the FoV it gives. Only "complaints" with this lens is that it's a little heavy and when on manual focus the focusing ring makes a noise that almost makes you think it's broken. I looked into this and apparently it's normal.
  • Pros: IQ, Nice Bokeh, speed, Strong Construction
  • Cons: Heavy, Weird noise

Unless you're willing to drop 2k on an equivalent L series lens, get this.

  • Summary: Great for star photography! Large aperture, wide angle lens. It doesn't really have that super ultra crispness that my canon primes do (35mm f/2, 50mm f/1.8) but it works incredibly well in low light.

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.
