The Canon EF 75-300mm f/4-5.6 III USM is a compact and lightweight 4x telephoto zoom lens designed for sports, portraits, and wildlife photography. Released in 1999, this lens represents Canon's budget-friendly telephoto solution for the EF mount system. The lens incorporates Canon's Micro USM autofocus technology, which provides quicker and quieter focusing compared to standard motors. With a focal length range of 75-300mm and a variable aperture of f/4-5.6, it offers significant reach while maintaining a relatively compact form factor. The optical construction consists of 13 elements in 9 groups with 7 diaphragm blades. The lens has a minimum focusing distance of 1.5 meters and supports a maximum reproduction ratio of 1:4, allowing for decent close-up capabilities. Weighing only 480g with dimensions of 122 x 71.0mm, it remains highly portable for extended shooting sessions. The 58mm filter thread accommodates standard screw-on filters. While lacking image stabilization, the lens compensates with its lightweight design that reduces camera shake. The improved zoom mechanism provides smoother operation, and the front part of the zoom ring features a silver accent for aesthetic appeal.
