Photographer Dustin Abbott shares an in-depth review of the Sigma 15mm F1.4 Contemporary lens for Sony, Canon, and Fuji APS-C mirrorless
dustinabbott.net
AI SUMMARY: The Sigma 15mm F1.4 DC | Contemporary lens is an impressive addition to Sigma’s APS-C lineup, offering an enticing alternative to competitors like Sony’s 15mm F1.4 G at a more affordable price point of $579. With a versatile focal length suitable for street photography, landscapes, and portraits, it also features a fast aperture for enhanced creative flexibility. The build quality has improved with better weather sealing and a slightly more upscale design, making it competitive in the market. Despite some issues with vignette, distortion, and fringing, overall optical performance remains strong, making this lens a valuable choice for various mirrorless platforms.
Strengths:
- Compact and lightweight design, enhancing portability.
- Fast F1.4 maximum aperture for versatile shooting in various lighting conditions.
- Competitive pricing compared to first-party alternatives, providing excellent value.
- Improved build quality with weather sealing and a smooth manual focus mechanism.
- More vignette and distortion than the previous Sigma 12mm F1.4.
- Slightly less sharpness compared to the wider 12mm lens.
- Some chromatic aberrations noted, particularly at close distances.
- Reliance on digital corrections for optical flaws can be a concern in certain scenarios.
Pros:
- Value for Money: At $579, the Sigma 15mm F1.4 offers a compelling alternative to premium lenses like Sony’s 15mm F1.4 G, which is priced nearly $950.
- Fast Maximum Aperture: The F1.4 aperture allows for shallow depth of field and excellent low-light performance, making it a versatile lens for creative photography.
- Compact and Lightweight Design: Weighing around 220g and measuring 64mm in diameter, it is lightweight and easy to carry.
- Improved Build Quality: The lens features enhanced weather sealing and a premium design, with an aperture ring and smooth manual focus operation.
- Fast and Accurate Autofocus: Equipped with a stepping focus motor, the autofocus is quick and nearly silent, performing well in various lighting conditions and for both photo and video applications.
- Strong Optical Performance: Provides high sharpness even wide open at F1.4, with commendable image quality across the frame.
- Effective Flare Resistance: Demonstrates good flare resistance, allowing for well-contrasted images when shooting toward light sources.
- Good Color Rendition: Produces rich, saturated colors without appearing overly exaggerated, enhancing overall image appeal.
- Compatibility: Available in multiple mounts (Sony E-mount, Fuji X-mount, and Canon RF), catering to a broad range of photographers.
Cons:
- Vignetting and Distortion: noticeable vignetting and barrel distortion that may require digital correction in post-processing.
- Less Sharpness Compared to 12mm: While sharp, it is slightly less sharp than the Sigma 12mm F1.4, particularly in the corners.
- Chromatic Aberration: Some longitudinal chromatic aberrations and green fringing occur, particularly at close distances, potentially affecting image quality in precise scenarios.
- Dependence on Digital Corrections: The high level of optical corrections needed can be a downside for those who prefer less reliance on post-processing.
- Bokeh Quality Issues: While better than many wide-angle lenses, the bokeh can exhibit “cat-eye” effects near the corners, which may be undesirable for certain uses.
- Comparative Performance with Alternatives: Although strong, performance is slightly outclassed by some competitors at smaller apertures, especially when comparing against lower-priced options like the Viltrox AIR 15mm F1.7 in specific settings.

Με ETZ21 Pro Megadap τελευταίο firmware.
Συμπερασματικά:
- Έχει σχεδόν native AF.
- Τα πάντα όλα από modes δουλεύουν κανονικά.
- Πάρα πολύ κοντά σε prime f4 σε ότι αφορά ποιότητα εικόνας.
- Κάπου στα 5.5 κιλά με Ζ9 (κάτι λιγότερο με Ζ8).
Πραγματικά, εάν είχα 7.5 χιλιάρικα θα ήταν αυτόματη αγορά.
Είναι ο φακός όνειρο για πανίδα, εφόσον έχεις πολύ περισσότερη ευελιξία στα κάδρα σε σχέση με τους prime.
