DIY 35mm DOF Adapter for Canon HV20/HV30/HV40

Here we have my first build of a 35mm Depth of Field adapter for my Canon HV30. I used tutorials and some parts ordered from Daniel Schweinert at JetSetModels. I constructed the DOF adapter with Canon EOS tubes and purchased a Nikon adapter ring for my lenses. I plan on using my HV30 with Nikon SLR lenses, but figured it would be a good idea to make the DOF adapter compatible with both types.

When I first started researching DIY DOF adapters it seemed like rocket science to me, but after doing a lot of reading and asking poor Daniel a bunch of questions I decided to go ahead with the build. Below are photos of the DOF adapter construction process, a parts list along with cost and where I found everything, and a list of the tutorials I used from Daniels website. I will follow up with the electrical wiring part later on. Hope this clarifies the process a bit for those that were on the fence about building their own Depth of Field Adapter. My parts list below should be very complete, let me know if I overlooked something. My next DIY will be a rod and rail support with an inverted mount to hold this monster!
