이 리뷰 사이트 결과로는 주변부는 오투스 85 보다 낫다고 합니다.크롭 바디 주변부에 해당되는 부분은 오투스가 낫고요.
그런데 제 테스트로는 아트 85보다 소니 85GM이 주변부가 확실히 낫더라고요.그렇다면 소니 85GM이 주변부는 최강이란 소리?
Compared to Zeiss Otus 85/1.4
It's interesting to see how far the design of lenses have come in the last three years: Sigma started to aim at top performance with their "Art" series, Zeiss delivered top-notch optics in their Otus series and Tamron has also entered the fray with unassuming but well performing lenses, trying to differentiate themselves from the pack by adding image stabilization to their 35/1.8, 45/1.8, and 85/1.8 primes. Saying that the Sigma 85/1.4 Art beats the Otus in the FF/FX-corner is testament to the extraordinary performance of the Sigma. But in the center the Otus still delivers superior resolution with the APS-C/DX-corner on a par. And it has less longitudinal CAs. But the Sigma can produce the slightly softer Bokeh. Outside the optical performance both the Otus and the Sigma are large and heavy, something that not everybody will welcome. Regarding build quality the Otus seems to have an advantage over the Sigma with its unmatchedly smooth focus-ring and its tank-like build. But the Otus has two big disadvantages: it is manual focus only and it costs three times as much as the new Sigma. That makes the Sigma clearly better value for money. For further information about the Otus have a look at my Zeiss Otus 85/1.4 review.
Compared to Nikon AF-S Nikkor 85/1.4G ED
The Nikon AF-S 85/1.4G generally cannot match the new Sigma in sharpness, clarity and resolution and it has stronger longitudinal CAs. Build-quality is also lower than the new Sigma as the Nikon is mostly made from plastic although it is more expensive than the new Sigma. But the Nikon has the benefit of being much lighter at 595g and smaller (87x84mm). So if you need small and light and are prepared to pay for that, get the Nikon. Otherwise the new Sigma is the better choice. See my Nikon 85mm f/1.4G review for more detail.
Compared to Tamron SP 85/1.8 VC
The Tamron 85/1.8 VC is a unique lens: It combines optical performance almost matching Sigma's with image stabilization at a reasonable price. In fact it's the only stabilized large aperture 85mm prime for Canon and Nikon users. Its autofocus is reliable (after some tweaking) and the package is not too large or heavy to become intimidating. In direct comparison to the new Sigma the Tamron is a bit softer in the FF/FX-corner but has a little less longitudinal CA. Due to its f1.8 focal ratio the Bokeh of the Tamron is less soft wide open than from the new Sigma at f1.4. And its build feels plasticky compared to the Sigma. If you need the best Bokeh and the shortest possible shutter speed get the new Sigma. If you prefer a smaller and lighter lens and the benefits of image stabilization, the Tamron is a good choice. Head over to my Tamron 85/1.8 VC review for further information.
