Sigma's tiny Art-line wide prime for APS-C mirrorless — 28.5mm equivalent at f/2.8 in a pancake-like body.
The Sigma 19mm f/2.8 DN Art launched in 2013 as part of Sigma's compact Art-line primes for mirrorless cameras. Providing approximately 28.5mm equivalent on Sony APS-C E-mount, it offers a wide-angle perspective in an incredibly compact form factor.
Optically good for the size — sharp from f/4 with decent performance at f/2.8. Art-line designation means Sigma's optical quality standards apply. Linear AF motor is quiet and adequately fast. The compact size pairs well with small APS-C bodies like the A6000 series.
Sony E mount with 46mm filter thread. Weighs just 160g — near-pancake dimensions. No weather sealing. Minimum focus distance 20cm. Metal mount with plastic barrel. Available in silver and black finishes. Art-line cosmetics with fine surface texture.
Very cheap used — outstanding value for an Art-designated lens. Also available in MFT mount. The Sigma 16mm f/1.4 DC DN is sharper and faster but larger. A great budget wide-angle option for Sony APS-C shooters who want compactness above all.
