We had our first opportunity to shoot with the Sigma 30mm F1.4 Contemporary at CP+, spending some time with a pre-production lens taking in Japan's freshly snow-coated landscapes. With a full-production lens in hand and good weather in the air, we've put the Sigma 30mm through its paces a little closer to home. Designed for Micro Four Thirds and Sony E-mount cameras, the featherweight prime is at home on Sony's a6300 and a6000. Take a look at what this combo can do.

Quick Note on AF

On Sony E-mount cameras, this lens focuses stopped down at your shooting aperture (we're not certain if it's Sony camera bodies, or the lens, that dictates this behavior). This leads to increased chances of hunting as you stop down your shooting aperture: for example, if you're shooting at F5.6, you may notice the lens rack back and forth more than if were you shooting at F1.4, especially if you're in a continuous AF mode. Unfortunately, this behavior is becoming more commonplace as newer Sony cameras tend to be reluctant to open the iris for AF acquisition, but we've also noticed this 'stop-down focusing' to adversely affect some lenses more than others. This lens, along with Sony's own FE 50mm, in particular, can be problematic. Let us know your experiences in the comments below.
