Viltrox AF 27mm F 1 2 Pro Review | 54 Data compared

The Viltrox Pro AF 27mm F1.2 STM for Fujifilm X-mount is a premium, weather-sealed APS-C prime lens that delivers roughly a 40mm full-frame equivalent focal length. Sourced with high-quality Japanese Hoya glass, it features a complex optical formula of 15 elements in 11 groups that resolves exceptional contrast and sharpness across the frame even at F1.2. Optically, the lens boasts essentially zero distortion and outstanding control over lateral and longitudinal chromatic aberrations. Its autofocus is driven by a Lead Screw-type STM motor that is fast, accurate, and highly reliable for tracking eyes and general action during event or portrait photography. Furthermore, it addresses traditional Viltrox limitations by providing a much-improved minimum focus distance of 28cm (0.15x magnification) and features a built-in USB-C port for easy firmware updates. Despite its stellar performance, the lens compromises on size and weight, tipping the scales at 560g and measuring 92mm in length, which can make it feel front-heavy on smaller camera bodies. The lack of an AF/MF toggle switch—a feature present on the previous 75mm Pro lens—and a clicked aperture ring with no option...

The Viltrox AF 27mm F1.2 Pro is a highly impressive, fast autofocus prime lens designed for Fujifilm X, Nikon Z DX, and Sony E-mount crop-sensor cameras. Offering a 40.5mm equivalent focal length, it serves as an excellent, slightly wider option than a standard 50mm lens for everyday walkabout and street photography. The lens delivers astonishing sharpness and clarity even when shooting wide-open at f/1.2, keeping ghosting, flare, and both lateral and longitudinal chromatic aberrations to an absolute minimum. It features an 11-blade aperture diaphragm that produces exceptionally smooth, natural bokeh, alongside a fast, nearly silent linear stepping motor autofocus system that excels in both stills and video tracking. Additionally, its up-market design includes a customizable L-Fn button, an AF/MF toggle switch, a firm aperture ring with a click on/off switch for video, and a modern USB-C port for firmware updates. The core advantages of the lens are its robust, weather-sealed metal construction and its sublime handling and optical performance, all provided at a standout consumer price tag that makes it an absolute steal. On the downside, accommodating the ultra-fast f/1.2...

The Viltrox Pro AF 27mm F1.2 E-mount (Pro AF 27E) is an exceptional prime lens for Sony APS-C cameras that acts as a 40mm full-frame equivalent, making it ideal for street, general-purpose, and people photography. Optically, it is ridiculously sharp across the frame even at its maximum F1.2 aperture, delivering excellent real-world contrast and low chromatic aberration while maintaining lovely, soft bokeh rendering,,,,. Viltrox significantly upgraded the lens's design for Sony by packing in robust, professional-grade features, including an AF/MF switch, a focus hold/custom button, a declickable aperture ring for smooth video racking, a built-in USB-C port for firmware updates, and comprehensive weather sealing,,,. Additionally, its stepping motor (STM) provides fast, silent, and highly confident autofocus tracking for both action stills and eye-detection video focus pulls,,. Despite its stellar performance, the lens does come with a few notable drawbacks. The most significant con is its physical footprint; at 571g and 82mm in diameter, it is considerably larger and heavier than most competing APS-C prime lenses, compensating with high optical power much like early full-frame Sigma ART glass,,. Performance-wise, it exhibits...

The lens's primary advantage is its bright f/1.2 aperture, which gathers twice as much light as standard f/1.8 primes to melt backgrounds into beautiful, full-frame-style bokeh. However, this complex optical design makes the lens significantly bulky and heavy compared to typical APS-C options. Its stepping motor (STM) delivers quiet focus but suffers from relatively slow autofocus speeds and occasional hunting before locking onto a subject. For video creators, noticeable focus breathing causes a distracting blooming effect when shifting focus planes. Minor optical flaws include a cat's eye shape in corner highlights at wide apertures, light green and purple color halos (longitudinal chromatic aberration) in the bokeh, and a lack of built-in image stabilization. Raw files also exhibit barrel distortion and dark vignette corners unless software correction profiles are applied. Despite these minor drawbacks, its superb build and remarkable wide-open sharpness comfortably secure it an Editors' Choice award.

The Viltrox AF 27mm f/1.2 XF PRO is an outstanding, attractively priced APS-C lens for Fujifilm X-mount cameras that delivers exceptional value despite its $545 price tag. Optically, its biggest strength is its impressive sharpness, offering excellent center resolution and good-to-very-good outer image fields even wide open at f/1.2. Chromatic aberrations and image distortions are virtually nonexistent without auto-correction. Mechanically, it boasts professional-grade build quality featuring an all-metal body, weather-sealing with 10 distinct seals, a smooth focus ring, a clicked aperture ring, and a fast, silent stepping autofocus motor. However, the lens does compromise on size and weight, making it a relatively bulky option to accommodate its ultra-fast f/1.2 speed. In terms of optical flaws, it suffers from heavy RAW vignetting at f/1.2 (~2.7EV falloff), which requires auto-correction to become manageable. The bokeh, while generally smooth in the background, is not perfect; it exhibits a rapid "cat-eye" distortion near the image corners and noticeable bokeh fringing (longitudinal chromatic aberration) at wide apertures. Finally, due to its 11 rounded aperture blades prioritized for bokeh quality, its sun star rendering remains underdeveloped...

The Viltrox 27mm f/1.2 Pro lens for Fujifilm X-mount is a metal-constructed prime lens providing a full-frame equivalent focal length of 40.5mm, which functions well as a "human eye" general-purpose lens. Reviewers praise its stellar, professional-grade build quality and its refined aperture ring that clicks softly between stops. Optically, the lens is incredibly sharp even wide open at f/1.2, rendering highly detailed, high-contrast images with vibrant colors and pleasing bokeh that pair beautifully with Fujifilm's 40-megapixel sensors. Furthermore, its close focusing distance of 11 inches makes it highly versatile for nature work, while the fast f/1.2 aperture provides an excellent light-gathering advantage for poorly lit indoor or concert environments. However, the lens has several physical and technical drawbacks, including a heavy 1.2 lb weight and a bulky profile that may feel unbalanced on smaller Fujifilm camera bodies. On the design side, it lacks an aperture ring locking switch, leaving it prone to accidental shifting when set to the auto "A" position. Its stepping motor autofocus system is another significant downside; the reviewer and community members noted that the AF is...
