Lens Review
Introduction | Sigma 35mm F1.4 DG HSM A Sony mounted on Sony SLT Alpha 99 | Sigma 35mm F1.4 DG HSM A Sony Versus Sony 35mm F1.4 G both mounted on Sony SLT Alpha 99 | Conclusion

With a truly excellent overall DxOMark lens score of 34 points, the Sigma lens shows that it’s capable of replicating the high image quality associated with this optical design using a Sony mount. With a very 17P-Mpix Sharpness score, it’s one of the sharpest lenses available for the A99, and has terrific resolution in the center at full aperture.

Sitting in the top-slot, the Sigma 35mm f1.4 is the best performing model on the Sony A99 in our database, and one of the sharpest lenses available for Sony users.

Distortion is very mild and chromatic aberration, while fractionally higher than that seen on the Nikon mount, is still very well controlled. Vignetting is expected on high-speed lenses like this, but while it’s quite strong at full-aperture (varying from -1/3 EV at 50% of the image field to -1.3EV in the corners) it’s less than competing offerings.
