Not missing out on the flurry of announcements ahead of Photokina, Japanese glass-smiths Tamron are trumpeting their plans to start development on a new ultra wide-angle lens. Though it's still in the planning phases, said lens has target specs a working name: the Tamron SP 15-30mm F/2.8 Di VC USD (Model A012).
As its monker implies, this lens will zoom from 15-30mm. Said aperture assembly will use 9 blades, and be able to stay at a constant f/2.8 throughout the zoom range. Using 18 elements in 13 groups, this will be a hefty wide-angle—Tamron claims it'll be just under 2.5 pounds, which is quite a bit heavier than most glass in this focal range.
Despite the nebulous nature of development plans, Tamron plans to release this full-frame compatible lens in Sony, Nikon, and Canon mounts. Though no pricing or availability have been set, convention-goers at Photokina will be able to check out a working model at the Tamron booth.
