Best Sigma APS-C normal lens?

In this post, I’ll look at the different options to get an affordable APS-C lens in the 28-35mm range from Sigma. This translates as the equivalent of 42-52mm focal length on a full frame/small format/”35mm film” camera.

I’ve populated the field with three of Sigma’s new “Art” lenses – two primes and one zoom, as well as an older 30mm Sigma prime lens that was the predecessor of the new “Art” version with the same focal length. All four lenses are HSM (hypersonic motor) lenses.

As a bonus, I threw in the 28mm f/1.8 Macro, which is not an HSM lens. Test results are from DxOMark, technical information from Sigma.

I’ll mostly let the table speak for itself – as per convention, green is good, red is bad.

What you should notice is that while the 35mm f/1.4 Art is clearly an amazing lens, the 18-35mm f/1.8 zoom trails it only slightly in distortion and chromatic aberration, while being equally sharp. At the relatively slightly lower price, this looks like an amazing deal (but yes, it’s very long for a supposedly 35mm maximum zoom lens).
