Sony 85mm F14 G Master Fe Vs Sigma Art 85mm 14

Sony E-mountain shooters in the market for an 85mm prime number lens face a hard choice.  The Sony 85mm F1.4 GM or the Sigma 85mm F1.4 DG DN Art. Both lenses take been historic for their build and performance capabilities. However, if you're wondering if one of these models is superior to the other, yous're not the simply one. We decided to compare the Sigma 85mm F1.4 Art vs Sony 85mm F11.4 GM to find out  which lens is best .

The Backstory

The Brands

Over the last ten years, Sony has established themselves as one of the leading manufacturers of full– frame, mirrorless cameras. For this reason, some photographers prefer to exclusively pair their Sony camera with Sony lenses. After all, who would be better placed to produce a lens that matches the photographic camera'due south abilities than the same manufacturer? Of form, information technology'due south non that simple.

Sigma is not new to the lens game. In fact, they've been developing high-quality lenses since the 1960s, far longer than Sony. Over the past 60 years they've cultivated a reputation for excellence that has seen the family-owned company go the world's largest independent lens manufacturer.

In contempo years, both brands have released a multitude of loftier-powered lenses for total– frame mirrorless cameras, peculiarly in their corresponding premium lens lines. That is, the Sony K Master line and the Sigma Art line.

The Lenses

The Sony 85mm F1.4 GM lens was released in early 2016 to instant acclaim. The Sigma 85mm F1.4 HSM Art lens soon followed, although it was not immediately available in Sony E-mount or L-mount. Sigma remedied this in mid-2020 when they announced the Sigma 85mm F1.4 DG DN Art; a new, upgraded version of the lens that was specifically designed for total– frame, mirrorless cameras.

Suddenly, E-mount and L-mountain shooters had a new 85mm prime lens to consider. The Sony 85mm F1.iv GM is a fantastic lens, but it was already 4 years sometime when the new Sigma model was released. However, Sony are also known for future-proofing their products. They oasis't released a new 85mm F1.four GM lens considering, frankly, they don't need to. The lens easily competes with newer alternatives. The 85mm F1.4 GM is fifty-fifty 1 of few lenses that can go along up with the Sony a1,  Sony's new 50MP camera that boasts a 30fps continuous shooting speed.

Suffice to say, the Sigma 85mm F1.four Art  vs Sony 85mm F11.4 GM contest has sparked rigorous debate in the photography customs. By closely comparing the two lenses, nosotros've identified the strengths and weaknesses of each model. Nosotros hope the comparison beneath helps yous make up one's mind which lens is correct for you.

The Comparing

Sigma 85mm F1.4 Fine art vs Sony 85mm F1.4 GM

In addition to comparing the build and technical specifications of the Sigma 85mm F1.4 Fine art vs Sony 85mm F1.four GM, we wanted to see how the lenses performed in the field. 85mm is an excellent focal length for portraiture, so we took the lenses to a local park for a small portrait photography shoot. We paired the lenses with a Sony a7 III.

Build

Each lens is housed in a durable, aluminum body  sealed confronting dust and moisture. In addition to  a  focus ring  and AF/MF switc h , both models are equipped with a lockable lens hood, customizable AFL push button , aperture band, and discontinuity click switch. Additionally, the Sigma 85mm offers an aperture lock switch , although this  isn't its only advantage.

The Sigma 85mm F1.iv is lighter and more compact than the Sony 85mm F1.4. The Sigma lens weighs 22.2 oz (630g), versus 28.92 oz (820g) for the Sony lens. Sony'southward E-mount cameras, peculiarly the a7C, are designed to be ultra-meaty, so it's a nice advantage when the lens yous're using is as low-cal and minor.

The optical construction of both lenses is also impressive. The Sony 85mm F1.4 utilizes xi glass elements in eight groups, including three Actress-Depression Dispersion (ED) glass elements and a single farthermost aspherical (XA) element. The front element as well has a Nano AR Coating for suppressing flare and ghosting. Meanwhile, the Sigma 85mm F1.iv uses 15 elements in 11 groups, with five Special Low Dispersion (SLD) elements and 1 aspherical element. These comparable optics ensure both lenses deliver clear, well-baked visuals.

Autofocus

Sony cameras are known for their superior autofocus capabilities. Nevertheless, whatever camera is express to what the lens information technology's paired with can handle. Thankfully, both the Sony and Sigma 85mm F1.4 lenses are equipped with advanced autofocusing mechanisms that allow them to keep upwards with Sony'south in-camera autofocus system.

The Sony 85mm F1.4 uses an RDSSM (Ring Drive Super Sonic wave  Motor) to drive its  autofocus mechanism. The piezoelectric motor works in conjunction with dual sensors that discover rotation and lens group position to reach fast, precise autofocus. The Sigma 85mm F1.four utilizes a stepping motor for autofocus that is similarly fast and accurate.

Testing out the lenses in the field, the difference between their autofocus operation was negligible. Both lenses worked excellently with the a7 III's autofocus, including the Eye AF functionality.  The biggest distinction was that the Sony lens emits an aural grinding sound while autofocusing. The noise didn't disrupt or interfere with our shoot; at worst it'southward slightly irritating. But the Sigma lens was practically silent in comparison.

Prototype Quality

Both the Sigma 85mm F1.iv and the Sony 85mm F1.iv yielded images of fantabulous quality. The portraits nosotros captured were tack-sharp on the subject, with excellent contrast and color reproduction. Almost of the images also had smooth, pleasing bokeh, courtesy of the 11-blade diaphragm of each lens. We didn't encounter any issues with aberrations, ghosting, or flare.

If at that place is any difference in terms of overall image quality output, it's minor. We took great photos (and some non-so-great ones) using both lenses, and generally establish they were easy to handle, pairing well with the a7 Iii.

Toll

When it comes to price, the Sigma 85mm F1.4 DG DN Art has the advantage. The lens currently costs $1,199. That's $600 cheaper than the Sony 85mm F1.four GM, which is currently bachelor for $1,798.

Spec Comparing

Comparison the technical specs of the Sigma 85mm F1.4 Art vs Sony 85mm F11.4 GM  side-by-side helps analyze the small-scale differences between the two lenses.

The Verdict

The Sigma 85mm F1.4 Art vs Sony 85mm F1.4 GM is a tough contest. Given that the Sigma lens closely compares to the Sony in terms of performance, while offering a smaller body and more affordable toll tag, we feel it is the improve value lens. Nevertheless, given that both lenses offer fantastic operation capabilities housed in a sophisticated build, there is no incorrect choice.  Either lens would make a bully addition to any E-mountain or L-mount photographers camera bag.
