New Sigma 150mm f2.8 Macro OS, 120-300mm f2.8 OS (and two variations of EF-610 flash unit)
This concludes the catch-up-a-thon to the major announcements up to right now. We will get to the smaller stuff later in the week. Sigma surprised everyone when they dropped a new SD1 DSLR with a 46mp/15mp Foveon sensor, but before that announcement, came two new lenses and a new flash unit with two variations. Let's have a look...
Sigma 150mm f2.8 Macro DG EX OS (stabilized) HSM
Sigma is going through an optical stabilization (OS) phase with their new lenses and that's a good thing - at least according to fans of OS. The new 150mm f2.8 macro is a 35mm full frame lens, with 1:1:, 38cm minimum focusing distance, 19 elements in 13 groups, and things like that.
Sigma 120-300mm f2.8 DG EX OS HSM
Zoom-zoom with this one, with all the buzz words (OS, HSM, f2.8, EX). This has weather resistant construction but shockingly Sigma hasn't coined a "WR" to put in the lens name :) The lens takes 105mm filters, has 23 elements in 18 groups (you know it's not a prime!), nine-blades (take than Gillette Mach 4), f22 minimum focusing distance, and things like that.
Sigma EF-610 DG Super and EF-610 DG ST flash units
Sigma has two new flash units, a "Super" and an "ST". Due to time constraints we move ahead in our Photokina coverage. Check the press releases below...
