I second the request for info. Waiting for Birger is no longer an option.
I'd really like to hear how the RR livelens works with the Tokina, and the 24-70mm F2.8?
I'm going to pass on the RR unit. I just does not seem to be a very elegant solution given the price for what it does along with their 9-volt battery dongle.
I'll keep on doing it the old fashion way until a better solution comes up.
I'm working on a comprehensive list of lenses that are supported. I can tell you from experience the 24-70mm works great. Working on traking down a Tokina 11-16 to test out personally due to its popularity
