Leica L-mount 100-400mm f/5-6.3 DG DN OS Contemporary Lens by Sigma

Introducing the Leica L-mount 100-400mm f/5-6.3 DG DN OS Contemporary lens from Sigma, a versatile telephoto zoom that combines impressive reach with a compact design. Featuring low dispersion glass elements, this lens ensures high clarity and colour accuracy throughout the zoom range while effectively suppressing chromatic aberrations and colour fringing. With intuitive handling, a stepping motor enables fast and near-silent autofocus performance, complemented by fine-tuned manual focus control. Additionally, four-stop-effective optical image stabilisation reduces camera shake for sharper handheld shooting, and compatibility with the optional TS-111 Tripod Socket ensures steady shooting atop a tripod or monopod.

As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes:

• Telephoto zoom is designed for full-frame L-mount mirrorless cameras but can also work with APS-C models where it provides a 150-600mm equivalent focal length range.
• One F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and colour fringing throughout the zoom range for improved clarity and colour accuracy.
• Optical image stabilisation compensates for up to four stops of camera shake to help realize sharp imagery when shooting handheld with slower shutter speeds.
• Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.
• At the 100mm end of the zoom range, a minimum focusing distance of 3.7' is available, and at the 400mm end, the minimum focusing distance is 5.2' with a maximum magnification of 1:4.1.
• Rounded 9-blade diaphragm contributes to a pleasing bokeh quality.
• Integrated AFL button can be programmed to adjust various shooting settings and the lens also features a focus limiter switch for faster focusing performance within certain distance ranges. There is a zoom lock switch to prevent the barrel from accidentally extending.
• Brass bayonet affords improved mounting accuracy and rigidity, and rubber sealing is incorporated in the mount's design to render it dust- and splash-resistant.
• Compatible with optional TS-111 Tripod Socket for working atop a tripod or monopod; the included PT-31 Protective Cover can be attached to the lens to maintain a seamless appearance if the tripod socket is not used.
• This lens is compatible with the optional Sigma UD-11 USB Dock for fine-tuning different lens characteristics and updating its firmware, as well as being compatible with the optional Sigma TC-1411 1.4x and TC-2011 2x teleconverters.
