I just managed to flip hack my Sony HC7. Too many pictures to put here. go over to my blog at GT35pro DOF 35mm Adapter. (http://gt35pro.blogspot.com/) to see how it's done.
If anyone own a HC9 or SR series, I would like to know if it can be done the same way. Thanks.

I opened up my A1U before a long time ago. It's the same thing.

Really? I think most consumer Sony models work the same way. The A1u is actually a pro version of the HC1. I bet it's the same with the SR series.
