“Panasonic 100-300mm f/4-5.6 was significantly sharper than the Olympus 75-300 f/4.8-6.7 II lens throughout the entire aperture range, and especially at 300mm”
“both lenses sharpest at f/8”

reviews
-
“extremely light weight, internal focus, silent, reasonably fast AF in good light”
sharpest at f/5.6 at 75mm, f/5.6-f/8 at 150mm and f/8-f/11 at 300mm
moderate CA at edges is worst at 150mm which may need correcting

it seems that best results are at the 100-220mm range with shots at longer focal length being much less sharp, although camera shake is likely a major factor at such high magnifications.
the IS apparently only gives 1-2 stops advantage
-
CA and vignetting very well controlled
“nice bokeh”
“While this lens is obviously not in the same class as the primes and high-grade zooms that we have reviewed so far, it is actually pretty amazing for a superzoom.”
“The lens also earns our admiration for fast focusing on the equally new DMC-GH2, even at the 600mm equivalent end of the zoom range in low-light conditions”
not as sharp as the Olympus lens?
-
great value for money when used in average light, shot at f/7.1, ISO 1000 for birds on branches, etc
main issues are significant lateral CA and AF issues in low light
