Telephoto zoom for Sony E-mount
The SIGMA 100-400mm f/5-6.3 DG DN OS Contemporary is a full-frame mirrorless lens built for Sony E-mount cameras. It covers a 100-400mm focal range with a variable maximum aperture of f/5-6.3 and a minimum of f/32. Optical construction uses 22 elements in 16 groups, including one FLD and four SLD elements to control aberrations. A built-in optical stabiliser provides up to four stops of correction.
Suited to wildlife and sports shooters needing reach
Photographers who want a single lightweight telephoto zoom for hand-held field work will benefit from the 2.5 kg weight and 67 mm filter thread. The stepping motor drives fast, quiet autofocus suitable for both phase-detection and contrast-detection systems. Buyers who require a constant f/2.8 aperture throughout the zoom range or a wider angle of view than 24.2 degrees should consider other options.
100-400mm focal range decides fit
The 100-400mm span is the specification that determines whether this lens matches the intended subject distance. At 400mm the angle of view narrows to 24.2 degrees, while the minimum focus distance of 5.25 m allows frame-filling shots of distant subjects. If the required working distance falls outside this range, a different focal length will be necessary.

Questions about this item
What filter thread size does the 100-400mm lens use?
The lens has a 67 mm filter thread, so any 67 mm circular filter will fit directly.
How do I attach this lens to my Sony E-mount camera and what step is often missed?
Align the white mounting index on the lens barrel with the matching dot on the camera, twist clockwise until it clicks, then set the focus-mode switch to AF before shooting.
When should the optical stabilisation unit be serviced or replaced?
The built-in OS mechanism is sealed and not user-serviceable; if stabilisation performance drops, the lens must be sent to an authorised Sigma service centre for internal repair.
