There’s no doubt about the fact that Sigma lenses are some of the sharpest currently available. From the 18-35mm f1.8 Art that shook the world of APS-C cameras a few years back, to the super sharp 135mm f1.8 Art that was released last year; sharpness hasn’t ever really been an issue with Art series lenses. Just how much sharper can their lenses possibly get though? Quite a bit it seems. Kai Wong recently took this massive prime lens out onto the streets of London during a Santa festival to see how it would perform, and of course in typical Kai style, hilarity ensues and it’s all caught on video; which we just happen have for you just after the break.
