Ideal for Nikon F-mount portrait work
This SIGMA 85mm f/1.4 DG HSM Art lens is built for FX-format Nikon F-mount cameras and also works on DX bodies with a 1.5× crop factor. It suits photographers who need a fast, short-telephoto prime for shallow-depth-of-field portraits, low-light events or studio detail work. The lens is new and ships in black with a brass bayonet mount.
Maximum aperture f/1.4 for depth control
The f/1.4 maximum aperture is the single specification that decides whether this lens fits the shooter’s creative intent. It gathers substantially more light than f/1.8 or f/2 alternatives, enabling faster shutter speeds indoors and a very thin plane of focus for subject separation. The nine-blade rounded diaphragm renders smooth, circular bokeh highlights when stopped down slightly.
Optical formula and dock compatibility change
Fourteen elements in twelve groups include two SLD low-dispersion elements and one aspherical element to suppress chromatic aberration and sagittal coma flare. Super Multi-Layer Coating reduces ghosting, while the Hyper Sonic Motor delivers quiet AF with full-time manual override. Sigma USB Dock compatibility lets owners update firmware and micro-adjust focus calibration without sending the lens to a service centre.

Questions about this item
How does the f/1.4 maximum aperture perform in low light?
The f/1.4 aperture gathers ample light for indoor or evening shooting without flash, and the nine-blade diaphragm produces smooth background blur for subject separation.
What does the Nikon F mount mean for lens communication and aperture control?
The brass Nikon F bayonet provides full electronic coupling for autofocus and aperture control from the camera body, and the lens also accepts Sigma USB Dock firmware updates.
Will the 86 mm filter thread and 3.64 kg weight require a specific tripod collar or support?
The lens weighs 3.64 kg and uses 86 mm filters; a tripod collar is not included, so a sturdy head or optional collar is advisable for extended handheld or tripod use.
