Sigma 100400mm F56.3 DG DN OS | Contemporary Lens L Mount

The Sigma 100400mm F56.3 DG DN OS | Contemporary is a compact ultra-telephoto zoom lens designed specifically for full-frame mirrorless cameras. Often described as a Handy Tele Master, it combines strong optical performance with a lightweight design, making it ideal for wildlife, sports, travel and everyday telephoto photography.

Built using Sigmas DG DN optical design, the lens delivers high-resolution and high-contrast images across the entire zoom range while maintaining a portable form factor suitable for field use. The versatile 100400mm focal range allows photographers to capture distant subjects with impressive compression and background separation.

Compact Ultra-Telephoto Zoom for Mirrorless Cameras

Designed exclusively for mirrorless systems with a short flange distance, the lens offers a strong balance of image quality, portability and usability.

Despite its powerful zoom range, the lens remains compact enough for everyday photography, making it suitable for:

• Wildlife and bird photography

• Sports and action photography

• Travel and landscape compression shots

• Everyday telephoto photography

Its lightweight construction encourages photographers to carry it more often, opening up new creative opportunities.

High-Resolution Optical Performance

The lens features a state-of-the-art optical design that delivers sharp and detailed images throughout the zoom range.

Key optical benefits include:

• High resolution from centre to edge

• Excellent contrast across the frame

• Strong performance across the entire focal range

This level of image quality complements high-resolution mirrorless cameras and pairs well with standard zoom lenses such as the Sigma 2470mm F2.8 DG DN | Art.

Smooth Autofocus and Video Performance

The lens uses a stepping motor autofocus system, optimised for both phase detection AF and contrast AF systems used by mirrorless cameras.

This allows for:

• Smooth autofocus operation

• Reliable tracking performance

• Compatibility with eye-tracking AF

• Quiet focusing for video recording

These features make the lens suitable for both still photography and video work.

Optical Stabilisation for Handheld Shooting

Built-in Optical Stabilisation (OS) helps reduce the effects of camera shake when shooting handheld at long focal lengths. This is particularly useful when working with ultra-telephoto focal lengths such as 400mm, where even small movements can affect image sharpness.

Beautiful Telephoto Compression and Bokeh

The ultra-telephoto focal range allows photographers to create strong background compression and attractive bokeh, isolating subjects from their surroundings.

This provides a unique visual style often associated with telephoto photography, making everyday scenes appear more dramatic and visually striking.
