LensTip published their full in-depth review for the new Sigma 12-24mm f/4 DG HSM Art lens. Boasting the renowned Global Vision image quality from center to edge, the new Sigma 12-24mm F4 features the largest aspherical glass mold in the industry, offering photographers an ultra-wide angle zoom with virtually no distortion, flare or ghosting. And the Sigma 12-24mm f/4 DG HSM Art lens ($1,599) is much cheaper than the Canon EF 11-24mm f/4L USM lens ($2,799).
I was really curious about the duel between the Sigma and the Canon. Obviously the Canon provides a tad wider focal range and it does so on wide angle, an important feature. On the other hand the Sigma costs $1599 while you have to pay for the Canon $2799. With such a huge difference in prices the results reached by the Sigma should be assessed very positively. Spherical aberration makes it lose in the resolution category at the maximum focal length but it is able to compete with the Canon on equal terms at the shorter end. What’s more, the Sigma is notably better when it comes to lateral chromatic aberration, distortion, vignetting or the performance against bright light. These are very substantial arguments and it seems the Sigma will be able to draw a lot of prospective customers of the more expensive Canon. Read the full review…
