Sigma AF 30mm f/2.8 EX DN (Sony E mount) - Review / Test Report
9 February 2013
Conclusion: The Sigma AF 30mm f/2.8 EX DN is a cute little fellow but not only that - it's good quality stuff, too. This is especially true for the center performance which is nothing short of breathtaking in the relevant aperture range. The image borders & corners aren't quite as hot but decent enough for sure. Distortions are basically absent and you don't really need to worry about vignetting that much either.
Summary: The Sigma 30 mm EX DN is a lens that is comfortable in the hand, finished solidly and which focuses quickly and quietly. For a micro-43 lens, the Sigma 30 mm EX DN is not very compact, but that is precisely an advantage for those who wish to focus manually. The resolution of this lens is very high, comparable to the resolution of the twice as expensive Panasonic 20 mm . This makes the Sigma 30 mm EX DN a welcome addition to the range of micro-43 lenses.
Pros: High resolution in the center, Solidly built and beautifully finished, Free pouch, Low priced
Cons: No built-in image stabilization, Reasonable performance in terms of distortion and chromatic aberration, Resolution in the corners is less than in the center
