One of the biggest complaints that users of Sony’s Aps-c format E-mount cameras such as the A6000 have is the lack of good, inexpensive prime lenses. In my recent long term review of the A6000 I made this point, and I wished for an equivalent to Fuji’s excellent 35mm f/1.4. In fact, the lack of a good fast native prime for the format has been a real issue. Fortunately Sigma has just addressed that gap in the lineup with the launch of the new 30mm f/1.4mm prime lens for e-mount (and m43).
