Sigma just announced a 1-pound 18-250mm F3.5-6.3 lens, ranging from macro to medium telephoto dedicated for APS-C sensors. Sigma redesigned the optical and structural design of this lens in order to achieve a relatively compact size, at 4.0" long, as well as a close minimum focusing distance of 13.8" for macro photography. Their Thermally Stable Composite (TSC) construction maintains the structure of the lens, with little variation despite changing temperatures. The lens also incorporates a brass-made bayonet mount, to further reinforce the lenses durability and resistance to wear and tear over time.
The lens will be available from July, starting with the Canon-mount version, with Nikon, Sony, Pentax and Sigma to follow.
Here are the product highlights:

  • Wide-Angle to Telephoto Zoom Macro Lens
  • Optical Stabilization (OS)
  • Hyper-Sonic Motor (HSM)
  • Thermally Stable Composite Material
  • Minimum Focusing Distance of 13.7"
  • 4 Special Low Dispersion (SLD) Elements
  • 3 Aspherical Glass Elements
  • Super Multi-Layer Lens Coating
  • Brass Made Bayonet Mount
