Re: Olympus 150-400 Rumour

The 1st December rumour on that web site mentions '2 telezooms' amongst other items to be announced.
Perhaps there is a fast zoom for professional sports photographers, and something slower & less expensive for enthusiasts?

I think a x1.2 teleconvertor makes sense for a fast long zoom - as it would be only ~1/2 stop slower.
Designing a top-notch teleconvertor for a zoom lens whilst avoiding bokeh problems across the zoom range must be very challenging - as shown from the occasional behaviour of the MC-14 with the 40~150 Pro zoom (which isn't seen when the MC-14 is used with the 300 f4 prime).
