Sigma 30mm f/1.4 DC HSM Lens Review (ephotozine)

Sigma 30mm f/1.4

ephotozine reviewed the Sigma 30mm f/1.4 DC HSM lens, a fast prime that’s interesting especially for Canon APS-C shooters. In the conclusion they write:

During this test, we did have issues with inaccurate focusing, which may be down to a flaw with the samples provided for review, and were able to resolve using the Sigma USB Dock. Presuming this problem isn’t widespread, then this lens is a great choice for owners of Canon cameras, after a high quality, standard lens with a fast maximum aperture.

The Sigma 30mm f/1.4, part of Sigma’s “Art” line-up,  retails for around $500/€490. The reviewers liked the good sharpness and build quality of the Sigma. However, they noticed that sharpness towards the edges is deteriorating, and some chromatic aberrations at maximum aperture. The review comes with test charts and sample pics.

From the product description:

The 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras from Sigma is a prime lens designed for Canon APS-C format cameras. Its 35mm focal length equivalent is 45mm which places it in the category of standard focal length lenses. With its particularly fast maximum aperture of f/1.4, the lens will perform very well in low light situations and provides shallow depth of field focus. With updated optical configurations (9 elements in 8 groups), as well as rounded aperture blades, the lens delivers sharp detail and nice background bokeh. Its minimum focus distance is 11.8″ (30 cm).

The lens’ optimized light distribution helps to minimize field curvature preventing a loss of image quality at the edges of photographs and its double-sided aspheric lens element minimizes spherical distortion. A rear focusing system combined with a newly developed autofocus algorithm and Hyper Sonic Motor provide smooth and accurate autofocus. Fulltime manual focus is also supported. As part of Sigma’s “Art” line of lenses it is compatible with Sigma’s new USB Dock, which enables firmware updates and focusing adjustments.

Fast maximum aperture of f/1.4 allows fast shutter speeds for clear low-light imaging and shallow depth of field focus.
A Hyper Sonic Autofocus Motor (HSM) offers fast, smooth and quiet autofocus.
Compatible with the Sigma USB Dock which enables firmware updates and focusing adjustments.
