Being a owner of five quality Sigma EX lenses, I am happy and impressed with the latest Sigma lenses announcements at PMA 08. The gigantic green beast Sigma 200-500 f/2.8 EX DG is a showcase of Sigma’s achievement in the photography lens market. Labeled as the “ultimate wildlife lens”, APO 200-500 f.2.8 is “the world’s first lens to offer an f/2.8 aperture at 500mm focal length”. It was actually displayed at PMA 2007 as prototype.
Following the trend in the lens market, Sigma is introducing and upgrading lens with its own optical stabilizer (OS) technology. Hypersonic focus motor is now quite a norm on Sigma lenses. Sigma APO 120-400mm f/4.5-5.6 DG OS HSM and Sigma APO 150-500mm f/5-6.3 DG OS HSM are likely good choices for wildlife and sports photographers. I have been using a Sigma 100-300 f/4 EX DG HSM with a 1.4x teleconverter to get the reach. It looks like one of the two new lenses will be a better solution. Sigma has claimed that its optical stabilizer function offers “the equivalent of using a shutter speed approximately 4 stops faster”.
