Looks like from what I have seen on the Panasonic site they have delayed or put on hold and maybe even cancelled the 150mm f2.8 I know this has bin posted already some where on the forum but my reason for posting this is to let panasonic know and other m4/3 lens makers there is a demand and need and want for a long tele lens. Even longer that the 150mm f2.8 Do we really need a 2.8?? Give me a 400mm or 500mm f4 I was using a leica 400mm f6.8 and have posted under the bird thread my results not bad for a old as dirt manual focus 20 some inch long lens. I want a native lens that is not manual focus, does it need IS yes and no both camera makers now have IS built in and really I would be using a mono or tripod on something that long anyway. Let make a statement by posting a we want a ____ blank tele lens and let them know. Fill in your _____ tele lens wants. I am sure someone from the OLY and PANNY companies monitor forums. Cheers to all the wild life and birders out their.
