Conclusion
Pros:
Excellent central sharpness and good edge resolution- Great contrast and color throughout the aperture range
- Compact and well-constructed lens
- Quick and accurate autofocus
- Minimal Vignetting
- Low Price
Cons:
- Moderate lateral chromatic aberration
- Average performance against bright light
- No phase-detect autofocus capability
- Lens body prone to fingerprints
The Sigma 19mm f/2.8 DN Art is, like the other two DN lenses, a high quality optic for an extremely reasonable price. While the lens doesn’t shine quite as brightly as the 30mm and 60mm lenses, it is nevertheless an excellent lens that produces sharp, contrasty and colorful images in a compact and tightly assembled body, for the bargain price of $199.
While the lens isn’t quite as sharp on the edges as the other Sigma mirrorless lenses, and has some moderate distortion and chromatic aberration, overall the imaging characteristics are excellent and the 19mm is capable of producing high quality images. Highly recommended!

Thanks for the review Jordan. I wish there were some full size samples to evaluate sharpness of the lens.
Otoh, i’m still expecting your conclusions about my XF23+X-A1 photos.
many thanks.
No phase-detect autofocus capability – what this mean?
The above conclusion was not appear in the reviews of Sigma 19mm f/2.8 DN Art and Sigma 60mm f/2.8 DN Art.
As I understand the both three lenses use the same technology.
Please advise.
it´s nonsense…. of course it works with PD AF.
No it’s not. Assuming it works like the 30mm, you get 8 or 9 center detection points in the heart of the frame, not full PD AF across the image. It is a major drawback on the 30, though for the image quality and price not necessarily a deal breaker. And it’s obviously even less of a concern if you’re primarily shooting landscapes with the focal length of the lens reviewed here.
