Sigma looks to have hit another home run with the release of the 85mm F1.4 DG DN – a prime optic for Sony E-mount and L-mount (Sigma, Leica and Panasonic) cameras that is sure to be a hit with portrait photographers.
Amazingly, the mirrorless version of the lens is 55% lighter than Sigma’s DSLR version of the 85mm lens and tips the scales at just 630g, which is near-unprecedented for a fast aperture f/1.4 prime yet Sigma explains that the mirrorless version actually offers improved image quality.
The 85mm is part of Sigma’s acclaimed Art series range of lenses and is built around a 15 elements in 11 groups design that features five SLD elements and one aspherical element. Also present is high-refractive-index glass, which Sigma says; ‘works to correct aberrations that cannot be effectively handled by in-camera correction. With a particular emphasis given to the elimination of axial chromatic aberration, users will enjoy sharp images with no colour bleeding all the way up to the maximum aperture of F1.4.’
With a filter size of 77mm, the 85mm F1.4 DG DN is also remarkably more compact that its DSLR stablemate and features a host of pro features such as a manual aperture ring that, with the flick of a switch, becomes declicked – useful for those using the lens to shoot video footage.
The 85mm F1.4 DG DN also features a stepping motor that is optimised for both phase detect and contrast AF and an iris ring lock switch, which allows photographers to lock the iris ring either at auto, or between apertures F1.4-F16. Lastly, the fast prime boasts an AFL button also allows various functions to be assigned from the camera body.
Built with a mix of aluminium and TSC (Thermally Stable Composite), the 85mm is dust and splash-proof, reinforcing its credentials as a lens for professional use that can take the rigors of everyday use. And in important information for portrait photographers, the 85mm F1.4 DG DN features an 11-blade rounded diaphragm to deliver enhanced bokeh.
Despite all the professional features, the lightweight Sigma 85mm F1.4 DG DN is also light on the wallet, beating rivals and carrying a price-tag of $1200/£999. Better still, photographers won’t have that long to wait before they can get their hands on the lens as it’s expected to start shipping towards the end of the month.
