Leica L-Mount

Review

The Sigma 85mm F1.4 DG HSM Art is an exceptional lens that has garnered a strong reputation among portrait photographers and those who value sharpness and bokeh. Designed for the L-Mount, this lens is a great addition to any serious photographer’s toolkit, whether you’re shooting with a full-frame camera or looking to explore the nuances of portraiture.

Build Quality and Design

The Sigma 85mm F1.4 Art lens boasts a premium build quality that is characteristic of the Art series. The lens is constructed with a robust metal body that feels solid in hand. The matte black finish not only adds to its sleek aesthetic but also reduces glare during shooting. The weather-sealing makes this lens relatively robust against dust and moisture, allowing you to brave different shooting conditions with confidence. It's also relatively heavy, weighing in at approximately 1,200 grams (2.65 lbs), which might be a consideration for those who prioritize portability.

Optical Performance

Optically, the 85mm F1.4 Art lens performs exceptionally well. It has an impressive set of features, including 14 elements in 12 groups, with a couple of special low dispersion (SLD) elements that help minimize chromatic aberration. The combination of a wide maximum aperture of F1.4 and the lens's optical design affords photographers the ability to create stunning images with beautiful bokeh that enhances foreground subjects while gently blurring out the background.

Sharpness is outstanding across the frame, even when shooting wide open. Many users report that images retain a high degree of detail and resolution, making it perfect for both professional portraiture and casual snaps. The lens also handles flare and ghosting well, which is crucial for outdoor shoots under challenging lighting conditions.

Autofocus and Usability

The autofocus system is driven by a Hyper Sonic Motor (HSM), providing quick and accurate focusing, which is essential for capturing fleeting moments during portrait sessions. Manual focus is responsive and smooth, allowing fine-tuning that many photographers appreciate. However, there have been occasional reports about the autofocus being a bit slower in low light situations compared to some of its competitors.
