Viltrox AF 28mm F 4 5 Z Review | 54 Data compared

The Viltrox 28mm f/4.5 VCM ASPH ED is an exceptionally thin full-frame autofocus lens measuring just 15.3mm thick and weighing 60g, earning it the nickname "Chip" due to its body-cap-like dimensions. Designed with a built-in sliding front lens cover that eliminates the need for a traditional cap, its ultra-portable form factor effectively transforms compact full-frame cameras like the Sony A7C series into high-end point-and-shoots. Despite its diminutive size, it includes electronic contacts to transfer EXIF data to the camera and features a built-in USB-C port on the aluminum bayonet mount for seamless firmware updates. Optically, the lens delivers good central sharpness at its fixed f/4.5 aperture with minimal lateral chromatic aberration and a pleasant 8-ray sunstar effect when shooting into light sources. However, the reviewer notes several compromises resulting from this ultra-compact design. The Voice Coil Motor (VCM) autofocus system is exceptionally quiet, but its speed is equivalent to entry-level lenses and occasionally suffers from inconsistent repeatability, sometimes failing to immediately reacquire focus in a continuous series of shots. The most significant optical weakness is its high susceptibility to veiling...

The reviewed article by Emanuele Dello Strologo highlights the Viltrox 28mm f/4.5 pancake lens as an exceptionally lightweight, compact, and affordable option that revitalized his passion for street photography. Testing it on a Sony Alpha 7IV during an autumn day in Milan, the photographer notes that its tiny profile transforms a full-frame camera into an agile, non-obtrusive, and highly instinctive tool. The 28mm focal length is praised for capturing wide urban landscapes and street scenes effectively without causing noticeable edge distortion. He describes the post-production process as a pleasant surprise, pointing out that the lens yields crisp details, clean contrasts, and natural color rendering that far exceed expectations for an economic lens. While the review is highly enthusiastic about the lens's price-to-performance ratio, it specifically highlights several pros and cons. The pros center around its premium portability, solid construction, natural color reproduction, and high sharpness despite its ultra-low price point. On the other hand, the primary con mentioned is its limited f/4.5 maximum aperture, which inherently restricts the depth of field and limits the softness or intensity of the background...

The Viltrox AF 28mm F4.5 VCM ASPH ED is an ultra-slim, metal-constructed pancake lens that covers full-frame sensors and mirrors the exact thickness of a body cap. Priced around €100, its standout benefits include surprising center sharpness, lightweight build quality, an integrated lens-barrier switch, and a built-in USB-C port for firmware updates. It features an autofocussing system that proves reliable on Fujifilm X-mount cameras, and its vintage-style character pairs exceptionally well with Fuji film simulations. It is highly recommended for street photography due to its sheer pocketability and high fun factor. However, the extreme compactness demands significant compromises, most notably a completely fixed F4.5 aperture that cannot be changed. Additionally, it completely lacks filter threads, making it impossible to attach lens hoods or physical filters. Optically, the lens suffers from very poor flare resistance, experiencing a severe loss of contrast under direct or harsh frontal lighting. While a great niche item for those wanting maximum portability, users who do not specifically need a lens this thin should consider less compromised alternatives like the TTArtisan AF 27mm F2.8. Are you considering...

The Viltrox AF 28mm f/4.5 is an ultra-compact pancake lens designed for Sony E-mount full-frame mirrorless cameras, functioning almost like a body cap due to its extreme portability. Weighing only 60 grams and measuring just a couple of centimetres thick, it features a fast, silent autofocus motor and an internal optical design with six elements, including two aspherical and two low-dispersion lenses. The lens has a fixed aperture of f/4.5 and completely lacks manual focus or aperture rings, offering a strict "point-and-shoot" experience with a 22cm minimum focusing distance. The major advantages (pros) of this lens are its highly affordable price, extreme lightweight compactness, and good sharpness at the center of the image, making it an excellent choice for street and travel photography. Its distortion is also well-controlled. On the downside (cons), the fixed f/4.5 aperture restricts low-light performance and prevents deep, creamy bokeh. Additionally, the image corners can appear slightly soft, vignetting is present, and the autofocus capability becomes less reactive when paired with older Sony camera bodies.
