Sharing this news which I saw this at DPreview - Tokina has a new 70-200mm f4 lens announced and it is their first image stabilized lens. Also announced on Kenko-Tokina site.
I think this is good news for all. It offers direct competition against Canon's offerings and new options for likes of Nikon users and other brands. Only a mock-up version is on show at CP+, so might be a while before it is available. Knowing Tokina, the lens will likely be very well built, just hope not too heavy personally.
