This is the Midwest Photo review of the new Sigma 40mm f/1.4 Art Lens by Spencer Lookabaugh.

In this review Spencer touches on 3 main points: Sharpness, Focusing Speed/Accuracy and a comparison to the two other Sigma Art lenses that are very close to focal length to the 40mm. Enjoy!

Here is a little more about the Sigma 40mm f/1.4 Art:

The 40mm F1.4 DG HSM Art is Sigma’s first lens developed originally to live up to the sought-after angle of view and performance standard for a benchmark cine lens. This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration. Designed for exceptional sharpness at maximum aperture, this lens excels at available light photography. With less than 1% distortion and near non-existent sagittal coma flare, this lens demonstrates consistent optical results featuring both 8K-compatible resolution and a beautiful bokeh. It is available for Sigma, Nikon, Canon and Sony E mount camera systems.
