Take it with a grain of salt: I can’t say if this pic is authentic. It appears that the first picture of Sigma’s rumored 24-70mm f/2 DG OS HSM lens for full-frame DSLRs may have leaked on the web. I reported yesterday that Sigma is supposed to make a full-frame lens that is as innovative as the company’s 18-35mm f/1.8 DC HSM lens for APS-C sensors, that’ s a lens with constant f/2 and a zoom range 24-70mm. If the picture above is real, then the announcement shouldn’t be too far away. Kudos Sigma for another revolutionary lens!
