Why are you selling it? Thought you loved it! What are you replacing it with?
Thanks for the questions. It is a really nice package! I just don't get to use it enough unless I am shooting in one of my reef tanks. I live in Ohio, and I am not getting into the ocean nearly as much as I used to 
Is that the old back for the housing? Are they selling new backs?
Yes, this is the original back. I'm not sure if they are selling the new backs.
Is the gf1 the right serial number/ age to run the crazy good video firmware?
Are you referring to the 1080p firmware hack? That was the only thing that really came up when I searched on google just now. I didn't catch anything about the age of the camera, but just so you know, my camera is one of the earliest GF-1's. I ordered it in 2009 when I read a review of the 20mm f/1.7 kit lens. Serial number is:FV9SA101962
What version of software is it?
My body is 1.2 and lens firmware is 1.1.
Are you selling lenses too?
Yes, the 20mm is included. I do not have any other lenses for the camera.
