The Canon EF-mount 35-150mm f/2.8-4 Di VC OSD from Tamron is a flexible zoom characterized by its bright f/2.8-4 maximum aperture range and relatively compact, lightweight design for general use. The optical design employs both low dispersion glass and aspherical elements, which help to reduce chromatic and spherical aberrations throughout the zoom range for improved clarity and sharpness. Additionally, the lens features a moisture-resistant construction along with a front fluorine coating to support working in harsh weather conditions. Bright f/2.8-4 maximum aperture range suits working in available light conditions and also offers the depth of field control for isolating subject matter.Three hybrid aspherical elements correct for spherical and comatic aberrations, as well as distortion, for consistent edge-to-edge sharpness and illumination throughout the zoom range, as well as a reduction of sagittal comatic flare. Optimized Silent Drive (OSD) motor realizes notably quiet, fast, and precise autofocus performance and the lens offers a 1.5' minimum focusing distance throughout the zoom range for working with close-up subjects. Dual dedicated MPUs (Micro-Processing Unit) are used-one for autofocus, one for VC-to ensure fast, responsive focusing and stabilization performance. Electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
