We shoot with the EX1 and two 7D's, personally I feel the EX1 is still an amazing camera. I would not trade in a EX1 for a 7D, the two compliment each other. The 7D is a short term solution next year this time the 7D/5D will be old tech as the video world catches up to DSLRs. Our 7D's also constantly overheat which causes a lot of stress. If I had to choose one trust worthy camera it would be the EX1. Sell something else to fund a DSLR.

I think you have nailed it in your post Craig, SDOF, is just another option which if used correctly will add another dimension to the overall production.

Don't get me wrong, I am all in favour od HDSLR cameras and see them as an affordable option for boths SDOF and extreme wide angle shots - the long shots are well covered with my set of Nikon lenses and Adaptamatic adaptor. Hopefully we will be seeing some more developments from Nikon- in terms of more choice in shooting formats and frame rates. I have a lot of Nikon lenses.

The trend I was referring to was something being done in the very early days of digital imaging. You haven't missed anything special in current TV programs.

B&H has a massive subsection of their website devoted specifically to HDSLR description and use. It mentions all of the advantages and disadvantages that we've discussed. It's really worth the read through.

There are far more tabs than you'll initially see on the Left. If you keep using NEXT PAGE on the Upper Right it will take you into the next series of tabs.

Or even try moving along the line at the base of the screen.

All interesting stuff, I love the opening picture - Heath Robinson would have been proud of this construction.
