Sigma 30mm f/1.4 DC HSM A Review
What Digital Camera
7 October 2013
Summary: Overall, there is much to recommend this lens but it isn't in the same league as the stunning full-frame 35mm f/1.4 tested previously. Although the 30mm f/1.4 is worthy of serious consideration, potential purchasers must bear in mind that it possesses weaknesses as well as strengths.
Pros: F/1.4 maximum aperture; Excellent MTF results; Full-time MF option; Near-silent AF; Metal mounting flange
Cons: Significant barrel distortion; Some colour fringing; No image stabilisation
Summary: Sigma 30mm f/1.4 EX DC HSM is currently the only wide angle prime that was specifically designed for APS-C sensors and as such it has no direct competition. Nevertheless, users should carefully review the benefits this lens provides versus the more traditional FF type wide angles.
Excerpt: Originally published October 2005. WHAT YOU NEED TO KNOW: The first high-speed "normal" lens for digital SLRs with APS-sized sensors, this 30mm f/1.4 is Sigma's first nontele lens to incorporate elements of SLD (Special Low Dispersion) glass.
Conclusion: This is a ‘standard’ lens for a cropped digital SLR. 25 years ago, all SLR’s came with a ‘standard’ lens and everybody learned how to use one. Those lenses, at 50mm, are still about but don’t have the versatility that they had on a 35mm film camera.
Pros: Fast aperture, Picture quality, Consistent performance, Fast autofocus
Conclusion: I’m glad we’ve reached a moment in which the test of this lens, on all five mounts, appeared at our website. Its presence is important for a few reasons. First of all, it’s one of the few lenses which can be enjoyed by owners of all DSLRs with small sensors, thus making the comparison of the results...
Cons: poor image quality at the edge of the frame,, random accuracy of focus mechanism,, chromatic aberration should be slightly smaller,, too high distortion for these lens parameters,, very large astigmatism,, noticeable coma.
Excerpt: Sigma's 30mm f/1.4 EX DC HSM is a useful prime lens for the D-SLR owner with a cropped format APS-C type sensor. Essentially it takes on the role of prime standard lens, effectively offering 45mm (1.5x), 48mm (1.6x) or 60mm (2x) - depending on which camera you use it with.
Sigma AF 30mm f/1.4 EX DC HSM (Nikon DX) - Review / Test Report
3 January 2009
Conclusion: Even though the border performance is a little disappointing, there are applications for this kind of lens, of couse. This is a pretty interesting lens if you want to isolate a (near-centered) object from the rest of the scene using an ultra-large aperture setting.

Conclusion: A quite strange design priority but there're applications for this. This is a pretty interesting lens if you want to isolate a (near-centered) object from the rest of the scene using an ultra-large aperture setting.
Sigma AF 30mm f/1.4 EX DC HSM - Review / Test Report
22 July 2008
Conclusion: We all know that zoom lenses are compromises regarding speed and performance but we expect fix-focals to perform better than that. Sigma AF 30mm f/1.4 EX DC HSM may perform pretty good in absolute terms but for a fix-focal the lens disappoints a little.
