B&H (www.b&h.com) recently put up a few new interesting additions to their site targeted towards HDSLR film making. They have a new interactive section to better direct you towards HDSLR tailored options of products as well as a new, interactive guide to HDSLR's.
this would be great for someone who's just getting into HDSLR's, very basic, but it's a good place to start!
check it all out here:
