Designed to provide a wealth of control over out-of-focus quality and to enhance bokeh, the Laowa 105mm f/2 Smooth Trans Focus Lens from Venus Optics is a short telephoto prime designed for full-frame Canon EF-mount cameras. The unique optical design incorporates an apodization (APD) element, as well as two separate diaphragms—8- and 14-blade—to provide separate adjustment over the bokeh as well as the exposure and depth of field. This APD element functions as a radially graduated neutral density filter, and as such limits the light transmission to a T-stop value of 3.2, while permitting the depth of field and selective focus qualities of a true f/2 design.
Alongside the unique attributes of the APD element, the lens also incorporates three low-dispersion elements and one extra refractive index element to control chromatic aberrations and color fringing, as well as produce a great deal of overall clarity and sharpness. The lens is also characterized by its manual focus and manual aperture design, which provides a wealth of control over focus and exposure to benefit working with the APD element.
