Sigma 35mm f/1.4 DG HSM A (Art) Full-Frame Lens for Nikon F-Mount, Black {67}

Sigma's proven 35mm f/1.4 Art prime for Nikon F shooters.

The 35mm f/1.4 DG HSM Art launched Sigma's Art line in 2012 and immediately set a benchmark that first-party 35mm lenses had to answer. The 13-element, 11-group optical formula puts four SLD elements, one FLD element, and two aspherical elements to work controlling chromatic aberration and field curvature across the full 63.4° angle of view. At f/1.4 on a full-frame body, subject separation is immediate and the nine rounded diaphragm blades produce smooth, circular out-of-focus rendering in the background.

The Hyper Sonic Motor drives fast, near-silent autofocus with full-time manual override, no mode switching required. The floating inner focus system shifts internal element groups without extending the barrel, which keeps aberration correction consistent down to the 11.81" (30 cm) minimum focus distance. Super Multi-Layer Coating keeps contrast honest when the light source ends up in or near the frame.

For those who want to dial in focus calibration without shipping the lens out, the USB Dock compatibility and Sigma Optimization Pro software let you adjust AF fine-tune parameters at home. At 665 g with a brass bayonet mount and a non-rotating 67mm filter thread, this is a working lens built to the weight and durability expectations of daily professional use.

Who It's For

Documentary and photojournalist photographers get a wide-angle lens that autofocuses quietly in mixed light and opens to f/1.4 when available light drops. Portrait shooters working on full-frame bodies benefit from the 35mm field of view for environmental work, with the nine rounded blades producing clean subject separation. Street photographers who fine-tune AF offset for a specific body will find the USB Dock calibration capability worth having. Wedding photographers moving between ceremony interiors and reception low-light situations can lean on the f/1.4 aperture without switching lenses.

FAQ

How does the floating inner focus system affect optical performance?

The floating elements shift internal groups without extending the barrel, which maintains consistent aberration correction from 11.81" minimum focus distance all the way to infinity. This design prevents the field curvature and astigmatism shift that happens in fixed-focus designs as you rack focus.

What autofocus performance should I expect?

The Hyper Sonic Motor delivers fast, near-silent AF with full-time manual override - rotate the focus ring without switching modes. There's no lag between autofocus and manual input.

Can I adjust the lens autofocus without sending it back to Sigma?

Yes. The USB Dock and Sigma Optimization Pro software let you fine-tune AF parameters and update firmware at home - no shipping required.

How does the bokeh rendering compare to other 35mm f/1.4 designs?

Nine rounded diaphragm blades produce smooth, circular out-of-focus rendering. The nine-blade count gives you more subtle transitions in the background than typical six or eight-blade designs.

What optical elements control chromatic aberration in the design?

Four SLD (Super-Low Dispersion) elements and one FLD (fluorite-like) element work together to minimize color fringing across the full 63.4° angle of view.

Is this lens weather-sealed for professional outdoor work?

No. The brass bayonet mount and internal metallic parts are built for durability, but the lens has no rubber seals or gaskets against dust and moisture.

What's the closest I can focus with this lens?

11.81" (30 cm) minimum focus distance, achieved without barrel extension because the internal focus system keeps the lens length constant.
