SIGMA 300-600mm f/4 DG OS Sports Lens

This SIGMA 300-600mm f/4 DG OS Sports lens for L Mount delivers a constant f/4 aperture across a 300-600mm zoom range. It uses 6 FLD and 1 SLD elements for high optical quality. The built-in Optical Stabilizer provides 5.5 stops of correction at 600mm. A High-response Linear Actuator drives fast, precise autofocus. The magnesium alloy body includes thermal insulation paint and a function ring. It targets professionals shooting sports, wildlife and aviation.

Practical limits of the constant f/4

The constant f/4 aperture holds exposure steady while zooming, but depth of field remains very shallow at 600mm. Optical stabilization reaches 5.5 stops at the long end, yet subject motion still requires fast shutter speeds. The 300-600mm range covers distant action, though subjects closer than the minimum focus distance cannot be captured. The lens accepts front filters, but the large diameter means filter cost and weight are significant. Buyers who need a wider angle or a faster maximum aperture should look elsewhere.

Installation and common issues

Mount the lens on any L Mount body; the HLA motor communicates directly with the camera for autofocus. The function ring can be customised via the camera menu for focus hold or other settings. The tripod foot rotates for vertical or horizontal orientation without remounting. Dust and splash sealing protects the mount and moving parts, though the extending zoom barrel can draw in air during operation. Firmware updates are applied through the camera body when released by SIGMA.

Questions about this item

Which focal-length range covers the type of distant subjects I want to shoot?

The lens zooms from 300 mm to 600 mm, so you can frame everything from mid-field action to tight wildlife portraits without swapping glass.

What does the constant f/4 aperture mean when I am tracking fast motion at the long end?

You keep the same bright f/4 opening at 600 mm, letting you hold a faster shutter speed and consistent depth of field across the whole zoom range.

How much shake correction does the built-in stabiliser give at 600 mm?

The Optical Stabilizer delivers 5.5 stops of compensation at 600 mm, letting you shoot handheld at much slower speeds than would otherwise be sharp.
