Canon RF 75-300mm f/4-5.6 Overview Expand your photographic reach with the lightweight RF 75-300mm f/4-5.6 Lens from Canon. A relatively compact offering for a telephoto zoom, this lens will partner well with Canon’s full-frame and APS-C mirrorless camera offerings and allow photographers to get closer to their subjects. The RF 75-300mm features a variable f/4-5.6 maximum aperture to maintain a small relative form factor, including a filter thread diameter of just 58mm. It is also lightweight at a little over 1 lb. It uses a DC autofocus motor to capture subjects in sharp focus and has a 4.9′ minimum focus distance with a 0.25x maximum magnification for getting nice, close-up images. Optically, the lens is optimized for sharpness and there is a Super Spectra Coating to reduce flare and improve contrast. For smooth bokeh, it has a 7-blade aperture diaphragm.
