I’ve rated the options with a [+] (or [++]), when it’s higher than common and even state-of-the-art, a [0] if it’s commonplace or simply common, and [-] if there’s a drawback. For comparability I take advantage of the Sony FE 50mm f1.8, the Sony FE 50mm f1.four ZA and the Sigma 50mm f1.four Artwork (“Sigma Artwork” for brief).

Alternate options

If you need a normal lens (45 to 58mm focal size) with a focal ratio of at the least f2.Zero and autofocus for Sony E-mount full-frame cameras there are fairly a couple of choices to think about, principally on the 50mm size. Consider although that precise 50mm lenses are barely wider than 55mm and it’s a must to crop 10% to attain the identical angle of view, which in flip would cut back the decision of a 42MP full-frame picture to 35MP. That mentioned, except you’re evaluating them side-by-side, a 50mm goes to really feel quite a bit like a 55.

  • Sony has two alternate options: the small and low cost FE 50mm f1.Eight from 2016 for 200 EUR / 250 USD (see my Sony FE 50mm f1.Eight overview which I’ll be finishing shortly). And there may be the FE 50mm f1.four ZA from 2016 for 1500 EUR/USD. It’s a lot greater and heavier than the FE 55/1.Eight ZA but additionally presents 2/three of a cease higher light-gathering energy. It earned a Extremely Beneficial in my Sony FE 50mm f1.four ZA overview.
  • Sigma presents their 50mm f1.four Artwork lens for E-mount since 2018. It’s an optical design from 2014 and got here Extremely Beneficial in my Sigma 50mm f1.four Artwork overview when examined on a 36MP Nikon D800 in 2014. It’s round 50% cheaper than Sony’s 50mm f1.four ZA.
  • Samyang has the AF 50mm 1.four FE from 2016 which sells for 480 EUR/USD.

Different alternate options embody handbook focus lenses or lenses with even shorter focal lengths. To get the angle-of-view of a 55mm lens from a 40mm although it wants a 38% crop which suggests nearly halving decision:

  • Sigma has their 40mm f1.four Artwork now additionally accessible for E-mount for 1200 EUR / 1400 USD. The lens is big and heavy however optically glorious. See my Sigma 40mm f1.four Artwork overview the place it earned a Extremely Beneficial. With its shorter focal size it’s a must to crop 25% to attain the identical angle of view as a 50mm lens which reduces your efficient decision of a 42MP full-frame sensor to 27MP.
  • Samyang has a number of handbook focus 50mm lenses considered one of which is the 50mm 1.four AS UMC which sells for round 350 EUR/USD.

How large is the distinction between 50mm and 55mm focal size? Right here is the angle of view that the Sony FE 50mm f1.Eight covers on a full-frame physique in comparison with the FE 55mm f1.Eight ZA:

Focus

Focus accuracy and repeatability is vital to persistently produce sharp photographs particularly with giant aperture lenses. Repeatability (the accuracy of concentrate on the identical topic after repeated focus-acquisition) of this lens is excellent (measured 97,6% in Reikan FoCal) with no outliers over a collection of 40 photographs. There’s a slight focus variation whether or not the lens focuses from a better distance or from infinity.

The lens focuses in round 0.7 sec on a Sony A7R II from infinity to 0.67m (1:10 magnification), which is comparatively quick and similar to the Sony FE 50mm f1.Eight and the Sigma Artwork (on a Nikon Z7 with FTZ adapter). The Sony FE 50mm f1.four ZA takes nearly 1 sec. The main target ring of the FE 55mm f1.Eight ZA is 21mm broad. It strikes very easily and may simply be operated with one finger. Each different Sony lenses additionally presents very easy focus by wire operation. Solely the Sigma Artwork has a a lot stiffer mechanical coupling between the main focus ring and the main focus motion.

AF-operation of the Sony lenses on this comparability is inaudible from the surface and in case you file video with the built-in microphone solely the FE 50/1.Eight registers a tiny little bit of noise. The Sigma Artwork produces an audible focus noise. As you pull focus, you’ll discover some focus respiration: the picture of the Sony FE 55mm f1.Eight ZA turns into 7% extra magnified when I adjusted the main focus from infinity to 0.67m. This may very well be distracting when taking pictures movies however is par for the course: the opposite lenses on this comparability all improve their magnification between 7% and 11%.
