Sigma 30mm f/1.4 DC DN – Verdict

Reasonable size and weight, excellent image quality, large f/1.4 aperture, superior build quality and a good price all mean that the Sigma 30mm f/1.4 DC DN | C lens is worthy of the consideration of Sony E-mount users. The 50mm-equivalent lens is versatile, and a step up from existing Sony options at this focal length. Micro Four Thirds users have a great deal more choice within this focal length. Having said that, the f/1.4 aperture can only be matched by the more expensive Leica 25mm f/1.4 Summilux, and given the performance of the Sigma lens, it would be difficult to justify the extra money.

With a retail price of around £300, it is hard to really fault this lens. Sharp images at f/1.4 and edge-to-edge sharpness when the lens is stopped down make this lens very appealing and a useful addition to your collection. If you have a Sony APS-C E-mount camera, you should certainly consider it. If you are a Micro Four Thirds user, it should be at the top of your ‘lenses to consider’ list.

    I agree with all that’s reported here, except for the matter of CAs. I found that even in a moderately backlit situation where the settings used throw the corners out of focus (think tree branches and leaves framing the main subject, but at a markedly different distance) the CAs were a major problem. I have never owned the PL 24mm 1.4 but from reports about CAs for that lens I think we’re probably talking about something similar. Would I buy the Sigma knowing that? Yes, because in many situations it won’t be a big problem.
    I also found that when the lens hood is stored reversed it is so deep it covers the focus ring to the point where the focus ring is all but impossible to use. It’s a bit of a loose fit, too.
    For the price paid it is remarkably good value and a real gem if you prefer the ‘in-between’ focal lengths.
