Sigma 15-30mm f/3.5-4.5 EX DG Aspherical review by Perudog
30 September 2014
Summary: If you have recently move to digital full frame ( Nikon d610 in my case), it won"t be long before you want to take advantage of the extra wide angle capability over cropped sensors. If like me you can't really justify the 14-24, this has prove to be a worthy substitute.
Pros: Terrific value for full frame when Nikon 14-24 is out of your budget...
Summary: Very nice lens, AF motor is not the quiet type, but it works great on my full-frame Canon and it is NOT a fish-eye in case that's isn't evident. Good luck finding a replacement lens cap for this one, it's a cheap piece of plastic that some swindlers are selling for $60.
Summary: Nice lens for the price.. Been looking to get a 17mm-50mm lens for my 5d mark ii.. These seem to be really good for landscape photography... They are some nice lens to have in your procession only if you are going to use them greatly..
Summary: I am so far, pleased with the lens, I recently got a Canon 5d, so I had to get rid of my Sigma 10-20 and replace it Wide angle lens that would work on a full frame. Since the Sigma 12-24 was out of my price range I settled with this one.
Summary: I was in the market for a wide angle zoom for full-frame Canon cameras (5DMkII). I purchased an older Canon 17-35 f2.8 L lens as my first choice, but I was not very happy with results. I own this lens in the Sigma SA mount, and loved it, so I found this one.
