While I did, in fact, spend $400 on a DIY HD mini-monitor, it handles both component and HDMI so I can use it on my A1 for hand focusing as well as the HV20. Overall I think I spent $1,000 for everything, but only about $100 is specific for the HV20.
For money spent on the 35mm adapter, matte box and rails. I can use all of that on other cameras including the A1.
The French Flag is actually offset off the axis and mounted upside down on the hinge. It came incorrectly assembled. I could take one side apart by hand but the other side was too tight and I couldn't find the right sized allen wrench. Murphy's law strikes again.
When flipped over the bottom of the french flag is much lower and fills the gap quite nicely now.
