Another competitor is entering the 24-70mm game for full-frame DSLRs. The Tokina AT-X PRO 24–70 mm f/2.8 SD (IF) FX was seen on display at CP+. The lens is rumored to be announced at Photokina later this year.
It’s getting crowded in the 24-70mm offerings. Besides Canon’s own EF 24-70mm f/2.8L II USM (price & specs) and EF 24-70mm f/4L IS USM (price & specs), there are also the Tamron AF 24-70mm f/2.8 VC (price & specs) and the also rumored Sigma 24-70mm f/2 OS HSM (expected to be announced during 2014) not to mention the highly popular Canon EF 24-105mm f/4L IS USM (price & specs) and the new, outstanding Sigma 24-105mm f/4 DG OS HSM (price & specs), which is defined as the new reference standard for professionals by DxOMark.[Optyczne via Photo Rumors]
