Utilizes Japanese HOYA material for an aspherical lens. Dust and splash resistant. The AF 27mm F1.2 Pro is the second lens in Viltrox's Pro flagship series with an extremely large aperture, following the AF 75mm F1.2 Pro. Unmatched bokeh with the powerful F1.2 aperture. The large F1.2 aperture creates an unparalleled blur effect, giving the image a deeper expression with a very shallow depth of field. No matter how complicated the background environment is, the subject stands out clearly and distinctly. Phenomenal sharp image quality. The image quality of the AF 27/1.2 Pro XF is sharp from the center to the edges, even when the aperture is fully open at F1.2. 27 mm is approximately equivalent to 40 mm in full-frame, which is close to the human eye's field of view. It can be effectively used for street, landscape, and portrait photography. Masterful close-ups with outstanding details. The AF 27/F1.2 Pro XF has a minimum focusing distance of just 0.28 m and excellent performance in close range. With ultra-high resolution at a professional level, not only are more details preserved, but the outstanding F1.2 large aperture effectively highlights the subject. The large aperture allows more light to pass through, and the excellent autofocus system minimizes the effects of camera shake.
