The Zeiss 25mm f2.Zero Batis is a wide-angle prime lens designed for Sony’s mirrorless cameras, and corrected to be used on full-frame our bodies. The 25mm focal size delivers a preferred field-of-view that’s wider than 28mm with out the distortion associated to even wider choices. Launched in 2015, the 25mm f2.Zero Batis is a less expensive, smaller, and lighter different to Sony’s flagship FE 24mm f1.Four G Grasp. It’s a part of a 5 lens “Batis” line-up, starting from 18mm focal size as much as 135mm which all characteristic a singular OLED show, indicating the focusing distance and depth-of-field vary at a look.
To learn how the Zeiss 25mm f2.Zero Batis performs I examined it towards the Sony FE 24mm f1.Four GM on the 42MP A7R II physique and examine it additionally to the Sigma 24mm f1.Four Artwork and the Zeiss 28mm f1.Four Otus. So in case you’re by which wide-angle prime to decide on, you’ve come to the correct place!
Details from the catalog
As common I’ll take a look on the technical knowledge of the Zeiss 25mm f2.Zero Batis first. I’ve rated the options with a [+] (or [++]), when it’s higher than common and even cutting-edge, a  if it’s normal or simply common, and [-] if there’s a drawback. For comparability I take advantage of the Sigma 24mm f1.Four Artwork and the Sony FE 24mm f1.Four GM (“Sigma Artwork” resp. “Sony GM” for brief).
Dimension (diameter x size): 81 x 73mm (3.2 x 2.9in.) plus 36mm for the lens hood (92mm diameter). The Sigma Artwork is way larger at 85 x 119mm (with out lens hood) because it was designed for DSLRs and has to bridge the distinction in flange distance. The Sony GM is 75 x 92mm + 31mm for the lens hood which is 95mm in diameter. [+]
Weight: 335g (11.Eight oz.) plus 25g for the lens hood. It’s the lightest of the lenses in contrast right here however then it has a one cease slower focal ratio. The Sigma Artwork is way heavier at 760g (26.Eight oz., with out lens hood). The Sony GM is in between at 445g (15.7 oz.) plus 33g for the lens hood. [+]
Optics: 10 parts (together with 5 aspherical parts alone) in Eight teams. The Sigma Artwork has 15 parts in 11 teams. The Sony GM has 13 parts in 10 teams plus fluorine coating on the entrance to repel water, mud, and grime and may make for simpler cleansing. [+]
Closest focus distance is 0.19m (7.5in.) in guide focus with a magnification of 1:4.8. A magnification of 1:10 is achieved at 0.32m distance. The Sigma Artwork and the Sony GM each obtain rather less magnification of 1:5.Three and 1:5.Four respectively. 
Filter-thread: 67mm, similar as with the Sony GM. The Sigma Artwork takes 77mm filters. [+]
Picture stabilization: No optical stabilization of the lens. The Sony A7 our bodies present built-in sensor-shift stabilization. Identical with the Sigma Artwork and the Sony GM. 
Auto focus: Constructed-in AF drive. Handbook-focus override is by merely turning the main focus ring. The main target ring has a non-linear gearing that enables for exact guide focus however makes easy focus pulling for videographers virtually not possible. The Zeiss additionally presents a singular show for focus distance and depth of subject. Sadly the show is tough to learn below sunny situations. The Sony GM has no distance markings but it surely comes with a customizable focus-lock button on the barrel and its gearing is linear which makes easy focus pulling for videographers simple. Deal with the Sigma Artwork works in a different way because it has a direct linear mechanical coupling between the main focus ring and the main focus motion. It additionally presents the space and dof markings that usually include lenses designed for DSLRs. [+]
Covers full body/FX or smaller. Identical with the competitors. [+]
Value: The lens at present sells for 1130 EUR (incl. 19% VAT) / 1200 USD. The Sigma Artwork goes for a lot much less: 730 EUR / 850 USD whereas the Sony GM is dearer at 1600 EUR / 1400 USD. 
The Zeiss Batis lens is available in a pleasant package deal however has no pouch which is a disgrace for a lens costing Four figures. The lens hood is included and is reversible for transport. The Sony GM and the Sigma Artwork include a padded pouch (however no strap for the Sigma) and the lens hood of the Sony is lockable. [-]
Aperture ring: no, identical to the Sigma Artwork. The Sony GM has an aperture ring. [+]
Sealing: sure, a rubber grommet on the lens-mount plus additional particular weather-sealing all through the development, identical to the Sigma Artwork and the Sony GM. [+]
The rating within the “features-department” is 1[-]/3/8[+], essentially the most distinguishing options of the lens being its small measurement and low weight plus the OLED show for distance and dof (however see caveat above). Plus it’s effectively protected towards the weather and prices lower than Sony’s different. However then the Zeiss Batis is just f2.0. A number of nit-pickings: Delivering the lens with no pouch and utilizing a barely seen dark-blue knob to mark the proper place of the mount weren’t essentially the most impressed design selections. And my copy of the lens was visibly decentered – not a great testomony of Zeiss’s high quality management.
In order for you a 24/25mm lens with E-mount, autofocus, and a big focal ratio there are solely two options:
- Sigma presents the AF 24mm 1.Four DG HSM Artwork (730 EUR / 850 USD). It’s an optical design from 2015 for DSLRs which is obtainable in E-mount since 2018. See my Sigma 24mm f1.Four Artwork assessment the place it earned a Extremely Really helpful.
- Sony has the FE 24mm f1.Four GM from 2018 for 1600 EUR / 1400 USD. It presents a spotlight lock button and a de-clickable aperture ring which is nice for videographers. See my Sony FE 24mm f1.Four GM assessment the place it earned a Extremely Really helpful.
When you contemplate barely longer, guide focus, or tailored lenses there are another options, e. g.:
- Sony’s FE 28mm f2.Zero from 2015 is a diminutiv lens of measurement 64 x 60mm and solely 200g weight. Because it has E-mount it wants no adapters and presents autofocus as effectively. It’s additionally the most cost effective of the options at round 400 EUR / 450 USD. However you get a 12% longer focal size. It may be remodeled right into a 21mm ultra-wide or 16mm Fisheye with a pair of non-compulsory converters and earned a advice in Gordon’s Sony FE 28mm f2.Zero review-so-far.
- Zeiss additionally presents the 28mm f1.Four Otus from 2014 which is guide focus solely and can be utilized on an EF to E-Mount adapter. The lens is extraordinarily massive and heavy (1.3kg) and sells for a whopping 4500 EUR / 5000 USD. However its optical efficiency is high notch. See my Zeiss 28mm f1.Four Otus assessment the place it earned a Extremely Really helpful.
- Samyang/Rokinon/Walimex has a 24mm f1.Four ED AS UMC lens for Sony E-Mount from 2013 however just for guide focus which prices round 540 EUR / 500 USD.
Focus accuracy and repeatability is vital to persistently produce sharp pictures particularly with giant aperture lenses. Repeatability (the accuracy of deal with the identical topic after repeated focus-acquisition) of this lens is excellent (measured 99.1% in Reikan FoCal) with no outliers over a sequence of 40 pictures below daylight at 9EV. Consistency dropped to 97,3% (which continues to be good) below incandescent mild. That in all probability is the Sony A7R II AF at work right here as I’ve seen comparable outcomes when testing the Sony 24mm f1.Four GM. There isn’t any focus variation whether or not the Zeiss Batis focuses from a better distance or from infinity.
The lens focuses in round 0.6 sec on an A7R II from infinity to 0.32m (1:10 magnification), which is quick. The Sony 24mm f1.Four GM is somewhat sooner at 0.5 sec whereas the Sigma Artwork is equally quick (however the Sigma was measured on a Nikon D810). The main target ring is 16mm vast. It strikes very easy and may simply be operated with one finger. My solely gripe is that the main focus ring is fairly near the digital camera physique: I typically missed it on the primary strive.
AF-operation of the lens is inaudible from the surface and in case you file video with the built-in microphone the AF-drive produces no sound. As you pull focus, you’ll discover some focus respiratory: the picture turns into 3% extra magnified when I adjusted the main focus from infinity to 0.32m. This isn’t too distracting when taking pictures movies.
Subsequent try my high quality outcomes!
