Sigma has announced their first Four Thirds System lens, the 18-125 mm DC Four Thirds lens. On a Four Thirds mount digital camera (the only one right now being the Olympus E-1) this seven times zoom lens provides an equivelant field of view of 36 - 250 mm. This lens is clearly the same 18-125 mm DC lens announced in May with a Four Thirds lens mount / communication protocol. This means that it's producing an imaging circle large enough for an APS-C size sensor.

A new zoom lens for the “Four Thirds System (4/3 System)”
Digital SLR Camera System

  • An all-in-one lens providing coverage of a wide range of focal lengths from wide angle to telephoto
  • The new Super Multi Layer lens coating reduces flare and ghost, which is a common problem with digital cameras
  • A Special Low Dispersion (SLD) and two aspherical glass elements produce a
    top quality optical performance
  • If the Olympus E-1 digital camera is used, the angle of view will be equal to 36-250mm focal length

Sigma Corporation is pleased to announce the launch of the new 18-125mm F3.5-5.6 DC for Four Thirds mount.

This zoom lens was exclusively designed for use with digital Single Lens Reflex (SLR) cameras and has a 1: 6.9 zoom ratio. A Special Low Dispersion (SLD) and two aspherical glass elements produce a top quality optical performance throughout the entire zoom range.

The new Super Multi Layer lens coating, which is optimized for digital SLR cameras, gives superb color rendition whilst cutting down flare and ghost. This lens has a minimum focusing distance of 50cm (19.6”) at all focal lengths and is equipped with an inner focusing system. As the front of the lens does not rotate, the Petal shaped hood and circular polarizing filters can be easily used. This lens is also equipped with a zoom lock switch that eliminates “Zoom Creep”.

* Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
