Ultra-Telephoto Zoom for L Mount

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary lens is built for full-frame mirrorless cameras using the L mount. Its optical design uses 22 elements in 16 groups, including one FLD and four SLD elements, to deliver high resolution and contrast across the 100-400mm focal range. A rounded diaphragm supports smooth background rendering.

Bundle Adds Protection and Workflow Extras

The included 67mm filter kit threads directly onto the front element for immediate lens protection or creative filtration. A cleaning kit, lens wrap, flexible lens shade, cap tether and pouch help maintain optical clarity and guard against knocks during transport. The Mac software kit provides a platform-specific toolset for lens firmware updates and parameter customisation.

Suited to Field Shooters Needing Reach

This lens suits photographers covering wildlife, sports or aviation who value a lightweight, weather-sealed telephoto zoom with built-in stabilisation. Buyers who require a constant f/2.8 aperture across the zoom range or a focal length wider than 100mm should look at alternative optics. The variable f/5-6.3 maximum aperture also limits low-light performance without higher ISO settings.

Questions about this item

How often will the 67 mm front filter thread need a replacement filter?

The 67 mm thread accepts standard screw-in filters; replacement is only needed if the glass is scratched or damaged.

Which optical element limits sustained sharpness at the 400 mm end?

The 22-element, 16-group design includes one FLD and four SLD elements that control aberrations across the full zoom range.

How much heat does the lens generate during all-day handheld shooting?

Passive metal barrel construction dissipates heat naturally; no active cooling is present, so temperature stays close to ambient.
