Here Amazing I think, just look at the shutter speeds... I can see the next 3 weeks as torture waiting for this lens on pre-order...I will be birding until late April with this lens. When I sold all of my Nikon gear I had a very specific set of lenses I "needed" - the 12-35 & 100-400 but I can see I will need to add the 7-14 & 35-100 to my kit. The 12-35mm has convinced me that the Panasonic PRO lenses are very good, the PL looks every bit as good which is amazing given the focal length. Even if you are not interested in this lens take a look, the images are pretty amazing for small birds.
