- Following the recent update by competitor Tokina with their ATX12-24mm F4 PRO Mark II, Sigma had just launched a new lens unit into this segment with it’s new Mark II of 12-24mm with HSM. I am sure landscape photographers will not be bothered with the aperture as most of them are shooting in the region of F8 & beyond. Meanwhile, let’s hope Tamron is working hard on their offering for the same range too. See below for the specs for the new Sigma 12-24mm – the Ultra Wide Angle Zoom lens.
– Designed for use with full frame digital cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 17-35mm with most cameras
- – One SLD and Four FLD glass
- – Minimum focusing distance of 11 inches
- – A front cap adapter, front/rear lens cap and carrying case are included with the lens.Sigma’s new 12-24mm F4.5-5.6 II DG HSM is an update to the 12-24mm F4.5-5.6 EX DG ASP HSM, which has been a photographer favorite since it was first introduced in 2002. Revisions to the lens include the inclusion of one Special Low Dispersion (SLD) glass element and four of the company’s new “F” Low Dispersion FLD glass elements to compensate for color aberration and provide high imagequality. FLD glass is the highest level, low dispersion glass available with extremely high light transmission and performance equal to fluorite glass. The new 12-24mm contains three glass mold elements and one hybrid aspherical lens for advanced performance and compact and lightweight construction. It also features Super Multi-Layer Coating to reduce flare and ghosting, and a Hyper Sonic Motor (HSM) to ensure quiet and high-speed autofocus, while allowing full-time manual focus override. Its minimum focusing distance is 11 inches throughout the entire zoom range; its maximum magnification ratio is 1:6.4.PRODUCT OVERVIEW

DG – DG for Digital* Nikon mounts do not have an aperture ring. Some functions may not work depending on the camera model. * FLD glass is the highest level low dispersion glass
available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to
current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum)
which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
* The appearance and specification are subject to change without notice.
