Sony 75-300mm f/4.5-5.6 Alpha A-Mount Telephoto Zoom Lens

Sony 75-300mm f/4.5-5.6 Alpha A-Mount Telephoto Zoom Lens
Expansive Telephoto Reach – Dynamic 4x Optical Zoom & 7-Blade Circular Aperture
The Sony 75-300mm f/4.5-5.6 is a versatile, far-reaching telephoto zoom lens engineered natively for Sony Alpha and legacy Minolta Maxxum-series A-mount SLR and DSLR camera bodies. Serving as a highly accessible option for budget-conscious wildlife tracking, outdoor sports coverage, and portrait isolation, this lens is optimized to squeeze impressive magnification out of cropped APS-C sensor systems. When mounted to a crop-sensor camera body, its focal profile transforms into a powerful 35mm-equivalent 112.5-450mm field of view, allowing shooters to easily frame distant action with a single compact zoom layout.

To deliver consistent clarity, the optical blueprint features a configuration of 13 glass elements structured within 10 specialized groups to control chromatic aberration and maintain clean image rendering across the entire 4x zoom timeline. Featuring a variable f/4.5-5.6 maximum aperture speed and a responsive internal iris system, it allows creators to transition effortlessly from medium-range portrait framing to tight, high-magnification telephoto close-ups.

Key Features & Optical Performance
4x Telephoto Zoom Flexibility: Designed for high-magnification versatility, offering an impressive 112.5-450mm equivalent focal stretch on APS-C cameras. This allows you to smoothly track erratic field sports or isolate timid wildlife without needing to change lenses.

Universal A-Mount Compatibility: Crafted with full cross-system adaptability, making it fully compatible with all Sony Alpha digital SLR/SLT camera bodies, as well as classic Minolta Maxxum-series film and digital SLR platforms.

7-Blade Circular Aperture Matrix: Employs a unique seven-blade circular iris assembly designed to form a near-perfect circle at wider apertures. This produces smooth, natural-looking out-of-focus background highlights and circular bokeh profiles when framing against pinpoint specular light sources.

Variable Aperture Implementation: Features a variable aperture range that shifts from f/4.5 to f/5.6 at its widest openings, scaling down to f/28 to f/32 at its narrowest margins for extensive deep depth-of-field control.

4.9-Foot Minimum Focus Capability: Outfitted with a minimum focusing distance of 4.9 feet (1.5 m) across the entire focal continuum, enabling crisp, tight telephoto detail captures of closer targets.

Standard 55mm Filter Interface: Outfitted with a highly common 55mm front-end filter thread, allowing for straightforward use with popular standard accessories such as circular polarizers and neutral density filters.
