The New 2017 Sigma 85mm F1.4 lens Image Quality Art Review

The Sigma 85mm F1.4 Art already on the marketplace, yet it has actually currently started to earn some significant waves. Lenstip and DxO have ranked it the sharpest 85mm lens ever before created, vanquishing also the fabulous 85mm F1.4 Zeiss Otus, which isn’t something that we take lightly. We were fortunate enough to obtain our hands on the lens back in mid-November and we were extremely impressed to say the least, a lot to ensure that it took leading honors for the ‘Ideal Prime Lens of 2016’ as picked by our team.

It has, undeniably, been a rather large subject of conversation not only among our personnel, yet also amongst picture digital photographers all over the world. With that said we just had to get our practical it to see exactly how it truly does as well as to see exactly how it holds up alongside some extremely stiff competitors at 85mm. The Sony FE 85mm F1.4 GM is an extremely awesome rival as well as probably the best modern-day 85mm F1.4 on the market (behind the manual focus Zeiss Otus, of course). With that in mind, the concern is; can the Sigma hold its very own? Our review will answer that inquiry as well as more.

Key Specifications

  • F1.4 maximum aperture
  • 85mm max fixed focal range
  • 2 SLD glass elements
  • 1 aspherical element
  • Canon EF, Nikon (FX) and Sigma SA Bayonet mounts

As you could see the lenses are fairly various in terms of develop as well as design. The Sony 85mm has a hand-operated aperture ring that could not just work by itself, yet the aperture could also be readjusted with the cam by changing the ring to ‘A’. This ring additionally showcases an unique de-click function for smooth, silent aperture modifications while shooting video clip. The Sigma 85mm does not have the weather condition securing that the Sony has and there’s also a fairly considerable distinction in size and weight as the Sony 85mm is a reasonable bit smaller as well as lighter. The price point is one area of the where the Sigma really prevails over the Sony, theoretically, at the very least.

In the adhering to sections we will certainly utilize DxO information and also the real world examples to establish just exactly how the Sigma 85mm F1.4 Art compares to the competition.

Bokeh and also Longitudinal CA

Here we’re looking at longitudinal (axial) colorful aberration (LoCA), which looks like green as well as magenta fringing on either side of the plane of focus. This has the tendency to be most prevalent on quick tops as well as it challenging to remove so you desire as little LoCA as possible if you’re wanting to fire wide-open. To do these tests, both the Sigma 85mm and also the Sony 85mm were installed to a Sony a7R II, the former via a Metabones smart lens adapter.


Originally, it does appear that both lenses take care of LoCA fairly well, with the Sigma 85mm presenting a fair bit much less LoCA at F1.4 compared to the Sony. The majority of the Sigma’s LoCA has vanished by F2.5, however it still lingers up until around F4 in the Sony GM (although only somewhat, the majority of it is gone by F2.8) where it is resolved completely.

Nonetheless, after closer examination we see that in more severe backlit scenarios the Sigma shows some fairly brilliant purple fringing when shot wide open at F1.4, which is only suppressed when you stop the lens down to F2.5. This was also verified in this real life example image with similarly rough illumination.


While firing the Longitudinal CA examination, we put a net of Christmas lights a few feet behind our Lens Align device to create stunning spheres of bokeh, giving us a method to picture differences between the two lenses’ out of focus qualities. Float your mouse over any type of offered aperture of any type of offered lens to have the major image button to a full-frame sight of the resulting shot.

Both the Sigma and the Sony show some extremely wonderful as well as smooth bokeh at F1.4, with little to no onion-ring or bulls-eye qualities. The Sony supplies a little smoother bokeh at F1.4, as well as offers a somewhat a lot more obscured background when contended the very same f-number as the Sigma. The longitudinal colorful aberration that could be seen on the fringes of the ‘bokeh rounds’ when shot at F1.4 is equivalent in both lenses with the Sigma carrying out a little much better compared to the Sony.

Auto Focus

In regards to AF performance the Sony 85mm GM is generally slower to secure emphasis when comparing it to the Sigma 85mm placed on an indigenous Canon body (5DSR and 5D Mark IV), especially while in live-view, making use of dual-pixel AF on the 5D Mark IV. Searching can be a little bit of a concern with both lenses, however that actually ends up being more of an issue in reduced light circumstances.

Final Word

How did the Sigma 85mm F1.4 Art compare with the G Master? The response, in other words, is that the Sigma defeated the Sony in virtually every group. Intensity, vignetting, distortion and the handling of side CA (though not LoCA, in extreme illumination scenarios, wide open) all mosted likely to the Sigma. It merely surpassed the Sony throughout the board. In regards to lens personality the Sigma does a superb job in subject isolation as well as overall bokeh presentation, yet so does the Sony. As a matter of fact, it’s really tough to see any major distinctions in this regard.

So, where do the differences beyond performance lie? One of the most glaring distinction is in rate; the Sony is a good deal more pricey, coming in at $1800 in contrast to the Sigma’s price of $1199. The following and also most obvious distinction is the size, the Sigma is large and extremely heavy compared to the Sony, (or even the Canon L for that matter). To be a lot more details, there’s a 311g (11oz) distinction in between the Sony as well as the Sigma. Last but not least, weather securing; the Sigma does not have any (dirt and dash evidence) whereas the Sony does. Now that the benefits and drawbacks have been laid out, what’s the last judgment?

Personally, I would certainly select the Sigma over the Sony, or even the Canon for that issue. Certain it weighes, but it out executed one of the very best contemporary 85mm prime designs in practically every category, as well as at 2/3 of the cost, which makes it an absolute bargain for the performance. Now, off to discover the nearest gym, so I could obtain used shooting with it.
