My extensive notes on the Vivitar and Tokina AT-X twins make no mention of internal focusing; hence I assume these lenses do not shorten in focal length at high magnifications. They do use floating elements. I have the Tokina, as well as the first of two tests that Modern Photography ran on it. The Tokina actually performed better at f/2.5 than stopped down! I routinely use it this way. But performance at 1:1 (using the 3-element adapter) was not as outstanding; just very good. Whatever its optical merits, users on the Olympus list and at least one other non-PDML forum have reported that the Vivitar has a flare problem at infinity because of insufficient baffling and the use of shiny surfaces inside. Tokina made the Vivitar and may have fixed the problem when introducing the AT-X version. [EMAIL PROTECTED]
