There aren't many ultra-wide angle lenses designed specifically for mirrorless and Sigma designed this to compete with the Sony 12-24mm f/4 G lens. Get your Sigma 14-24mm f/2.8 at B&H https://www.bhphotovideo.com/c/produc... A wide angle zoom is actually a challenge to design. First of all you want a lens that is going to retain sharpness throughout the entire focal range. Secondly lenses distort when they are wide so controlling this is important. And finally - wide zoom lenses in general are fairly challenging as they are prone to field curvature. Explain field curvature. Sigma did an amazing job with this lens on all counts and compete fairly on price. I think this lens is a real winner.
