A slightly long “normal” lens, the Sigma 30mm f/2.8 makes a compact companion to any Micro Four Thirds or Sony E mount (NEX) camera body where the goal is a slim form factor and minimal weight.
- On Micro Four Thirds, the Sigma 30mm f/2.8 is equivalent to a 60mm in its field of view and f/5.6 in terms of its depth of field (as compared to a 35mm DSLR).
- On Sony E mount (NEX, APS-C), the Sigma 30mm f/2.8 is equivalent to a ~45mm in its field of view and f/4 in terms of its depth of field (as compared to a 35mm DSLR).
This high-performance wide angle lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 38mm (35mm equivalent focal length) on the Micro Four Thirds systems and 28.5mm (35mm equivalent focal length) on the E-mount systems.
