  • Rumors hint at super-fast Sigma 50-100mm F1.8 Art lens for APS-C DSLRs

    Rumors suggest Sigma is getting ready to launch a 50-100mm F1.8 lens for APS-C cameras. Full specifications and convincing images of the lens have been leaked, suggesting the lens will be part of the company’s impressive ‘Art’ range. Such a lens would offer a fast partner to the company’s 18-35mm F1.8 Art lens, giving the same angle-of-view, depth-of-field and total light gathering capability as a ~75-150mm F2.8 lens on full-frame.

    Specifications reported on Digicame-info.com seem plausible, so we’re looking forward to next week’s CP+ show in Yokohama, Japan, to see if the rumors are true. We’ll be reporting from the show, so stay tuned for all the details.

    Lens construction (elements/groups) 21/15
    Filter size 82
    Minimum focus distance 95cm
    Aperture blades 9
    Length 170.7mm (mount not specified)
    Diameter 93.5mm
    Weight 1490g

     The site suggests a price of ¥167,400 (~$ 1500) and a launch date of April 22nd.

  • Sigma announces super-fast 18-35mm F1.8 DC HSM Art for APS-C DSLRs

    Sigma has announced the 18-35mm F1.8 DC HSM Art lens for APS-C DSLRs – the world’s first constant F1.8 zoom. The lens covers a 27-52.5mm equivalent range, though the company has not yet announced which mounts it will be offered in. There is also no announcement of a recommended price. The lens will offer the light-gathering and depth-of-field equivalent of a constant F2.7 on full-frame, which may under-cut the need for some photographers to change formats.
