The Viltrox pancake 28mm F4.5 Full-frame with Fujifilm X-mount – photographic lens for Fujifilm X mount is a compact and lightweight full-frame pancake lens, ideal for street and travel photographers. Weighing only 60 g and measuring 60.3 × 15.25 mm, it offers excellent portability, making it perfect for always being on hand. The optics consists of 6 elements in 6 groups, including 2 aspherical and 2 low dispersion (ED) lenses, which reduce chromatic aberrations and distortions. Multilayer HD Nano coating enhances contrast and sharpness, minimizing flare and ghosting.

A fixed aperture at f/4.5 enables good depth-of-field control and smooth bokeh rendition thanks to the 7-blade diaphragm. Autofocus, operated by a voice coil motor (VCM), is fast and quiet, compatible with the face and eye detection systems of Fujifilm cameras. The minimum focusing distance is 34 cm, with a maximum magnification of 0.1x, allowing close-up shots. The metal body lends robustness, while the lack of sealing against dust and moisture can be a limitation in harsh environments.

In summary, the Viltrox AF 28mm f/4.5 XF is an excellent choice for those seeking an ultra-portable lens for everyday use and travel, offering a good balance between optical quality and price.
