Most Helpful Review
"Buyers be advised. Sigma has yet to fix their quality assurance issues. Ordered this lens from Amazon and was delivered with a cracked element inside the lens. A very small deck that causes a lens flare on ever picture taken with it. How this passed QA going though the Art series technicians hands is beyond me. Sigma replied to my inquiry with Amazon / Happy Lens Mate isn’t an authorized dealer so I have to front the repair costs. Nikkor or Tamron from here on out."

It's certainly not a lightweight, but you have to remember this is a 14mm, f1.8 lens, so the compromise will be it's weight. That said my primary use is for Astrophotography where it's mounted on a tripod and weight isn't an issue. When accurately manually focused, stars in the centre of the image are pin sharp, but it has to be said those closer to the corners have noticeable coma, an issue common to most if not all super wide-angle lens to a greater or lesser extent. Stopping the lens down to f2.2 or 2.8 certainly helps and also the use of a star tracking device, which will allow for much longer exposures, minutes rather than seconds. It's certainly an improvement upon the lens I had been using for Astro, a Canon 16-35mm, f2.8 L, which itself is a first class lens.Overall I'm very pleased with the Sigma, but if you are reading this review as a potential purchaser you need to be aware of the drawbacks a lens of this type and quality brings with it. Life is all about compromises and if you can live with the minor compromises this lens has, then you won't be disappointed.The image in this review was an early attempt (with this lens) of the Milky Way, (f2.5, 30 seconds @ ISO 6400 using a tracker), which I'm fairly pleased with. Hopefully longer exposures at a future date will produce even better results. At over £1,200 the price is a bit 'salty', but at time of my purchase Amazon were as competitive as any other retailers.tim pearson
