Sigma 85mm f/1.4 EX DG HSM: A Fast, Full-Frame Prime
9 August 2012
Excerpt: The Sigma 85mm f/1.4 EX DG HSM lens (average price: $969 on various Internet sites) is designed for full-frame cameras; with an APS-C multiply by your usual factor. At about 25 oz, I’d describe the lens as substantial, but not hefty.
Excerpt: The Sigma AF 85mm f/1.4 EX DG HSM is a short telephoto lens with a bright f1.4 focal ratio. Announced February 2010, it's the only 85mm large aperture alternative to Nikon or Canon's own primes that offers auto-focus. The short telephoto lenses from Samyang and Zeiss are manual focus only.
Summary: Sigma has finally delivered an important lens which has been missing from the Pentax lineup for almost a decade: the new 85mm F1.4 EX HSM. Before its release, Pentax owners had to rely on the legacy FA* 85mm F1.4 , or its slightly slower and shorter cousin, the FA 77mm F1.8 Limited .

Conclusion: The Sigma AF 85mm f/1.4 EX HSM DG delivers a convincing performance on APS-C DSLRs although it stays somewhat short of the Canon EF 85mm f/1.2 USM L II here. The lens is impressively sharp in the image center - even at f/1.4 - but it's comparatively softer towards the borders/corners here.

Conclusion: It took Sigma quite a while but the Sigma AF 85mm f/1.4 EX DG HSM is finally here - their first ultra-large aperture tele prime lens. It was about time to get some serious competition (with AF) for the Canon EF 85mm f/1.2 USM L II.
Excerpt: Originally posted 2010-12-19 on Optyczne.pl The Sigma company’s line-up of lenses is really wide. In spite of that fact you could still find significant gaps there. Undoubtedly their line-up totally lacked classic portrait lenses as Sigma didn’t feature any fast devices with the focal ranges from 70...
Cons: coma in full frame corners is a bit too high,, manual focus ring not very precise,, noticeable longitudinal chromatic aberration.
