Upload & Sell: On
Yeah..right now that's a good deal. Last week, Amazon briefly had the GH2 for $499 and on Black Friday, you could briefly get the 12-35 for $999, but both deals seem to have passed. The 12-35 is a good lens, and if you were going to get both, it's a nice discount. I don't think you'll find either item much cheaper right now.
EDIT: Actually, the 12-35 can be bought for $1049 right now (though only a few in stock):
I've owned the GH2 and have the OM-D now. Quick summary between the two:
GH2 has better video
GH2 has more precise AF (size of AF point allows for very precise placing...accuracy is the same, but it's easier to hit what you want on the GH2)
GH2 has pop-up flash (though the OM-D includes the clip on flash that works very well).
GH2 has tilt and swivel screen vs just tilt on the OM-D
OM-D has better noise control above ISO 1600 (similar below that), especially at ISO 6400 and higher
OM-D has significantly wider dynamic range (I estimate about 2 stops)
OM-D's touch screen is better
OM-D has outstanding IBIS (better than the OIS on the Panasonic lenses, and works on everything)
So, pick what you like. Both are very good cameras.
I like the 12-50 Oly for its versatility (wide to telephoto with good macro), but optically, the 12-35 kicks its rear end.
