Sigma 14mm f/1.8 DG HSM Art Lens Sharpness Tests (by LensRentals)
Roger Cicala at Lensrentals.com has published the Sigma 14mm f/1.8 DG HSM Art Lens MTF Tests and he compared it to several lenses at f/2.8 including the Canon 14mm f/2.8L, Nikon 14-24mm f/2.8 and Canon 16-35mm f/2.8 III (at 16mm). And the new Sigma 14mm f/1.8 DG HSM Art lens is clearly better than the Canon 14mm f/2.8L and Nikon 14-24mm f/2.8, althouth the Canon & Nikon options are still very impressive lenses. And the Sigma 14mm f/1.8 Art lens has a much newer design.
Let’s face it, there hasn’t been an impressive 14mm prime for SLRs for a while, and I haven’t heard the natives banging on the castle doors demanding one. But for some people this is going to be a really fun lens. I consider it reasonably priced for what it is; a unique and excellent lens that hasn’t been made before. I shot real-estate for a brief moment in time, and I would have killed for this lens then. And I like playing with ultra-wide images in general, so I’m kind of excited about it. It won’t be a huge fraction of my images, but it will be a tool I didn’t really have before.
A lot of people will never shoot 14mm and will never notice this lens exists. But for those who do, the Sigma 14mm f/1.8 Art Lens is probably going to be a fascinating lens indeed. Read the full review
