Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens for L Mount

The Leica L-mount 100-400mm f/5-6.3 DG DN OS Contemporary lens, produced by Sigma, offers an impressive range within a compact framework. This versatile telephoto zoom lens combines a design that is easy to handle with commendable optical performance. It incorporates a series of low dispersion glass elements to ensure high clarity and color fidelity across the entire zoom spectrum, effectively minimizing chromatic aberrations and color fringing. The lens also features user-friendly handling, with a stepping motor that provides rapid and nearly silent autofocus, as well as precise manual focus adjustments. Furthermore, the four-stop effective optical image stabilization significantly mitigates the effects of camera shake, resulting in sharper images during handheld shooting. This 100-400mm lens is also compatible with the optional TS-111 Tripod Socket, allowing for stable shooting when mounted on a tripod or monopod.

This lens, part of Sigma's Contemporary line within the Global Vision series, is engineered to strike a harmonious balance between convenience and performance. It features a compact and lightweight design, offering versatile handling while delivering impressive optical qualities.

• The telephoto zoom lens is specifically engineered for full-frame L-mount mirrorless cameras; however, it is also compatible with APS-C models, offering an equivalent focal length range of 150-600mm.
  
  
• To enhance clarity and color precision, the lens incorporates one F Low Dispersion (FLD) element along with four Special Low Dispersion (SLD) elements, significantly minimizing chromatic aberrations and color fringing across the entire zoom range.
  
  
• Additionally, the optical image stabilization feature effectively counteracts camera shake by up to four stops, facilitating the capture of sharp images even when shooting handheld at 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.
  
  
• The integrated AFL button is programmable to modify a range of shooting settings, while the lens is equipped with a focus limiter switch that enhances focusing speed within specified distance ranges. Additionally, a zoom lock switch is provided to prevent unintentional extension of the barrel.
  
  
• The brass bayonet enhances mounting precision and stability, and the design includes rubber sealing to ensure dust and splash resistance.
  
  
• This lens is compatible with the optional TS-111 Tripod Socket, allowing for use on a tripod or monopod. Furthermore, the included PT-31 Protective Cover can be affixed to the lens to maintain a cohesive appearance when the tripod socket is not in use.
