Thanks Barry. The 1.6 teleconverter is a beautiful, great quality lens and it makes all the difference when I need that extra reach.
Long reach is one of the weaknesses of the DVX and if that really is a problem for you, I would suggest you look into a camera such as the XL2 with its 20x lens.
So far, however, the combo has worked well for me. There are plenty of examples of its use on my site if you are interested: http://www.pinelakefilms.com
