I've taken a course on video production, but it did not cover in depth what I needed to know about shooting with a camcorder. I have the Sony VX 2000 and I want to know about Iris settings, aperture, manual focus and depth of field. Can anyone recommend a good instructional video for using the manual features on a semi professional camcorder? Thanks in advance.

You might try taking a look at the VASST site - they have many instructional videos.
