The Viltrox AF 85mm f1.8 is a compact, lightweight portrait-length prime lens designed for full-frame Canon RF-mount mirrorless cameras. Measuring less than 10cm in length and weighing just 530g, this lens delivers professional-quality results in a portable package. The optical design features one extra-low dispersion element and four highly transparent elements that work together to reduce chromatic aberrations and deliver excellent clarity and colour accuracy. An STM stepping motor provides fast, quiet, and smooth autofocus performance ideal for both photo and video work. The bright f1.8 maximum aperture excels in low-light conditions and offers superior control over depth of field for creative portrait work. HD Nano multi-layer coating suppresses flare and ghosting for improved contrast when shooting in bright lighting. An AF/MF toggle switch on the barrel allows easy switching between autofocus and manual focus modes, plus a USB-C port supports future firmware updates.
