Sigma 321954 85 mm F1.4 DG HSM Art Canon Mount Lens - Black
About this deal
Yes, if you use the Metabones IV ;) like i use every of my EF-Lenses on A72 - everytime perfect focus. I've played with all manner of settings but haven't been able to nail down settings to guarantee a 95 percent or greater keeper rate on shots just yet.
The Sigma 85mm lacks the weather sealing that the Sony has and there's also a fairly substantial difference in size and weight as the Sony 85mm is a fair bit smaller and lighter.I know that it lacks autofocus, but with the Nikon mount, I can set the aperture and the focus fully manual.
lens are nowhere near as sharp as the Sigma Art on paper but I love the results and although I could easily trade towards Sigma I don't think it would be a clear upgrade.but this can actually be a desirable attribute for portraiture and still life photography, where the relative lack of extreme corner-sharpness can be similarly advantageous, literally focusing the attention on the main subject. Art lenses which are both are superb lenses but they simply cannot compare to my Otus 85mm or the 55mm. If mounting on a Sony body with an adapter, then the comparison becomes moot if you need all the AF features that the Sony bodies give you, such as Eye-AF and some of the AF point selection modes.
Sony have proven the days of third party reverse engineering are gone and third party lenses can compete with the first party lenses.
A star performer, this lens delivers fabulous image quality with superb sharpness and contrast, negligible color fringing and beautiful bokeh.
