Lens Overview — Sigma 300mm f/4
Key Features — Sigma 300mm f/4
300mm Prime Focal Length: A fixed 300mm perspective suits wildlife, sports, and portrait shooting where a dedicated telephoto reach is an advantage over a zoom.
f/4 Maximum Aperture: A wide-for-its-class maximum aperture allows faster shutter speeds and better subject separation than slower telephoto alternatives.
APO Apochromatic Design: Apochromatic glass elements correct chromatic aberration, reducing color fringing on high-contrast subjects at telephoto distances.
Macro Capability: Closer minimum focus distance than a standard telephoto prime, enabling tighter subject framing without a dedicated macro lens.
Full-Frame Coverage: Designed to cover the full 35mm frame, making it fully compatible with both full-frame and APS-C DSLR bodies.
Autofocus & Manual Focus: Supports both AF and MF modes, giving photographers the flexibility to switch based on subject type or shooting conditions.
