A current member of Sigma's Art line of lenses, the 30mm f/1.4 DC HSM lens updates a popular model from 2005 with a new optical configuration, a new hypersonic motor (HSM) autofocusing drive and rear focusing system. Full-time manual focus override is supported.

Despite the naming similarity, there is a world of difference between Sigma's 35mm f/1.4 and its 30mm f/1.4 (reviewed here). Whereas the former is a full-frame lens, the latter is APS-C only; whereas the former has a petal-shape lens hood, the latter's is cylindrical; whereas the former offers...

F/1.4 maximum aperture; Excellent MTF results; Full-time MF option; Near-silent AF; Metal mounting flange

Significant barrel distortion; Some colour fringing; No image stabilisation

This is a great lens, lets get that out there. Someone mentioned that it is a photographer's lens, and I agree wholeheartedly. This lens is PERFECT for indoor shooting, people shots, and as a general walk around lens.

Sharpness where it counts, light weight (this is relative), focusing accuracy on my copy, and great bokeh; If you get a good copy you will love it

None worth complaining about; it vignettes (correctable and typical for this type of lens); has some CAs (shoot RAW if you care about it); and people complain about corner sharpness; but if you are trying to get corner sharpness at f/1.4 your probably just shooting brick walls and test charts

The Sigma 30mm f/1.4 DC HSM A is a wide-aperture standard lens for APS-C cameras

F/1.4 maximum aperture; Excellent MTF results; Full-time MF option; Near-silent AF; Metal mounting flange

Significant barrel distortion; Some colour fringing; No image stabilisation

The Sigma 30mm F1.4 DC HSM "Art" is a fast prime lens designed exclusively for APS-C DSLRs; it's of particular interest to us because its "normal" field of view corresponds roughly to that of a 50mm lens on a film camera.

Fast F1.4 maximum aperture; Convenient focal length on APS-C; Beautiful bokeh; Excellent center sharpness; Compact and easy to hold; Minimal vignetting at F2 and above; Resistant to flare and ghosting; 4-year warranty (USA; Very affordable

More distortion that we'd like to see in a premium prime; Purple fringing near edges/corners; Low contrast wide-open; Somewhat heavy given its size; Average corner sharpness; Not weather-sealed; Sluggish autofocus

More like an iPhone 13S. The generational upgrades for the iPhone 14 are limited to a few subtle changes. At the same time, however, the base price climbs to 800 USD, while the only true innovation happens inside the iPhone 14 Pro series.

excellent OLED display, dust- and waterproof, fast Wi-Fi, wide range of supported frequencies, great camera, very fast performance, good battery life

display limited to 60 Hz, charging rate limited to 20 watts, no macro lens, wide notch

Yes, I would recommend this to a friend

Great solid heavy build; Nice Bokeh; Smooth and weighted focus

Corner Sharpness

If you don't know what you're talking about, don't review products, especially if you claim to have a high level of tech knowledge. Earwigy's criticism that the "depth of field is pretty bad" is a ludicrous statement. Without picking hairs, all f/1.4 lenses will have the same depth of field.

Relatively inexpensive, extremely fast prime; Autofocus is internal, pretty fast, and quiet; A little soft wide open, but sharpens up quickly as you stop down; Nice bokeh

A little soft wide open; If you upgrade to full frame, the lens is usless

Ett bra objektiv om man vill fota mycket i dåliga ljusförhållanden och klarar sig med en brännvidd på 30 mm.

Mycket ljusstarkt (F1,4; Ger bra kvalité i alla ljusförhållanden så man slipper dra upp ISO; Kompakt och litet objektiv med gedigen konstruktion; Personligen föredrar jag att fota med min Sigma 30 mm än tex Canon Ef 50 F/1,8; inte bara för att det är ljusstarkare utan gör att jag finner att 30 mm är

Fast brännvidd; något vissa kan tycka är jobbigt; Svårt att autofokusera i svagt ljus; man måste hitta en ljuspunkt att fokusera på; Brus i höga ISO
