Panasonic 45-150 or 100-300?

Hi guys!

I am a G3 owner looking for a lens that can be used for close-up portraits and zoo/wildlife (not birds). I have out-ruled the Oly 45mm as it's too close to my Sigma 30mm. Oly 60mm Macro is tempting but the lack of stabilization is holding me back. I am considering the Panny 45-150mm and 100-300mm.

So, does anyone have experience with these two lenses?

Kind regards
