Viltrox AF 25mm f/1.7 Air APS-C Lens for Fujifilm X Mount in More Detail
Fast and Reliable Autofocus
The Viltrox AF 25mm f/1.7 features a silent STM motor, for quick and precise autofocus when shooting both stills and video. The autofocus ensures sharp results without hunting for the subjects, and supports face and eye detection autofocus (on compatible cameras), enhancing portrait photography and video recording by keeping subjects in crisp focus.
Versatile 38mm Equivalent Field of View
The 25mm focal length (equivalent to 38mm on full-frame) provides a balanced perspective, which is wide enough for environmental shots, but natural enough for portraits and everyday general photography. This focal length is ideal for street photography, travel, interiors, and even group portraits, offering a versatile alternative to standard primes.
Compact and Lightweight
Weighing a mere 170g this prime lens is effortlessly portable. It is made with specialised lightweight materials, in order to provide a comfortable, low-profile shooting experience. Its pocketable size makes it easy to carry anywhere, and the compact design ensures a well-balanced feel on smaller APS-C cameras, which is ideal for handheld shooting.
Bright f/1.7 Aperture
The fast and bright f/1.7 maximum aperture offers excellent low-light performance, which is perfect for dimly lit environments where you won’t need to raise the camera ISO unnecessarily. A 9-blade diaphragm also creates smooth, natural bokeh, helping your subjects to stand out in the frame, with pleasing bokeh and soft background blur.
Sharp Optical Performance
Despite its affordability, the Viltrox AF 25mm f/1.7 includes a high-quality optical formula including:
- 1 extra-low dispersion (ED) element to minimise chromatic aberration and enhance clarity.
- 2 high-refractive index elements to improve contrast and detail.
- 2 aspherical elements for edge-to-edge sharpness and minimal distortion.
- HD nano multi-layer coating to reduce reflections, flare, and ghosting.
This combination delivers sharp details, vibrant colours, and natural contrast, ensuring high-quality results in a broad range of lighting conditions.
Close-Up Shooting with a 0.3m Minimum Focus Distance
With a minimum focus distance of 0.3m, the AF 25mm f/1.7 from Viltrox allows for great close-up shots, capturing small objects, food, or texture with clarity. This is perfect for creative compositions, whether shooting flat lays, documentary-style images, or portraits.
Optimised for Video
The lens delivers smooth, stable focus transitions with minimal focus breathing, ensuring a more immersive cinematic experience for your viewers. It also supports in-body image stabilisation (IBIS) on compatible cameras, helping to keep handheld footage more steady. The lightweight design further enhances gimbal compatibility, and this prime lens is a great option for run-and-gun video shooters and vloggers.
