I thought that said "price drop" for a second...

They charged me $1,699.99 that was the initial pre-order price at 5AM on March 10 so I might call B&H CS for a $2 credit ;)

My UPS guy just dropped my GH4 off so I now have the battery on charge. Here is a photo with Voigtländer Nokton 25mm f/0.95 and Rode Stereo VideoMic.
