Product Information

When stopped down, even extreme pixel peepers won’t find a flaw in sharpness. Optical Quirks & Flaws I’m also happy to say that the autofocus was very accurate. I rarely experienced missed shots, and this is important, especially when you consider the 16mm is an f1.4 lens, so sometimes, the depth of field can be pretty shallow, especially when you’re shooting closer.

SIGMA's DC DN lenses are made exclusively for mirrorless, and are designed primarily for use with crop sensor cameras. All DC DN lenses are available for Sony E-mount, L-Mount and FUJIFILM X systems, while our 16mm, 30mm and 56mm F1.4 DC DN | Contemporary lenses are additionally available for Nikon Z, Canon EF-M, and Micro 4/3. For weight, it comes in at about 14.3oz (405g). This heavy-ish weight, combined with the large size, made it feel slightly off-balanced, if I must admit, on my a6400.

Sigma 16mm F1.4 DC DN C Review - Amateur Photographer

The lens has the now standard nine rounded aperture blades that I’ve seen on most all the Sigma lenses I’ve reviewed in the last 4-5 years. I’ll comment more on the bokeh quality in a moment, but Sigma does a good job of maintaining a circular shape even with the aperture closed down a number of stops. Removal is sometimes very challenging, and in some cases, flare effects can be quite destructive to image quality.
