Pre-PMA 2005: The last of three DC (digital SLR only) lenses announced by Sigma today is the 30 mm F1.4 EX DC HSM, a lens which sounds extremely interesting on paper and will offer photographers an almost 'normal' 45 mm equiv. (on a 1.5x FOV crop digital SLR) with a super-fast F1.4 maximum aperture (great low-light focusing, lots of depth-of-field control). This lens also features Sigma's HSM (HyperSonic Motor) and will be available with Canon, Sigma and Nikon lens mounts.
Press Release:
Sigma 30mm F1.4 EX DC HSM
- Large Maximum Aperture of F1.4
- The most appropriate coating for digital SLR cameras
- Two SLD (Special Low Dispersion) glass elements and an hybrid aspherical lens, provides the utmost correction for all types of aberrations
- Equipped with HSM (Hyper Sonic Motor) system
Sigma Corporation is pleased to announce the launch of the new 30mm F1.4 EX DC HSM lens.
This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size
image sensors of digital SLR cameras. Two SLD glass elements are especially effective
in the compensation of magnification chromatic aberration. Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results.
From 40cm (15.7”) minimum focusing distance to infinity, this lens creates very sharp
images with high contrast.
The HSM models provide quiet high-speed auto-focus shooting, as well as full-time
manual focus. Large Maximum Aperture of F1.4 can perform superbly in a great range of
applications, including snapshots, portraiture, indoor shooting and landscape
photography.

Even though I had a zoom I noticed that most photos were taken around "normal". I wanted to explore that observation, and I changed to a prime lens. The effect on me and my photography was profound.
Canon's EOS R, the company's first full-frame mirrorless camera, impresses us with its image quality and color rendition. But it also comes with quirky ergonomics, uninspiring video features and a number of other shortcomings. Read our full review to see how the EOS R stacks up in today's full-frame mirrorless market.
No Nikon camera we've tested to date balances stills and video capture as well as the Nikon Z7. Though autofocus is less reliable than the D850, Nikon's first full-frame mirrorless gets enough right to earn our recommendation.
Nikon's Coolpix P1000 has moved the zoom needle from 'absurd' to 'ludicrous,' with an equivalent focal length of 24-3000mm. While it's great for lunar and still wildlife photography, we found that it's not suited for much else.
As a stills camera the Fujifilm X-T3 is a pleasant update to one of our favorite APS-C cameras, significantly improving the autofocus. If you're interested in stills and video, though, it's knockout.
The Nikon Z7 is slated as a mirrorless equivalent to the D850, but it can't subject track with the same reliability as its DSLR counterpart. AF performance is otherwise good, except in low light where hunting can lead to missed shots.
