I've been shooting HD for over a year now using Sony DVC 60 "Premium" DV tapes. The higher grade HDV (white package) $Sony tapes are for those who think they need them. Whatever tape you buy, stick with tapes from the same mfr as different tape lubrication methods used by various mfr's. can cause problems. My personal opinion is Sony tapes for Sony camcorders. You can also buy the DVC tapes really cheap on eBay in case lots(10). I recently paid well under $30 for 10 including shipping.
AFAIK Ikelite only makes
mechanical control housings. Possibly it's confusing because they offer electronic reversing circuitry on their mechanical housing
model# 6039.05 for the HC5. But all of the controls are purely mechanically (touch or control rod) activated.
The Ikelite accesses the LCD screen with a control rod. If you scroll through the menus you can access White Balance. With the HC cameras you can re-assign the MWB functions onto the main menu screen to make this easier. For now shoot in auto as the camera will do a good job of white balancing but later you may find that MWB will yield truer colors at depth. But it's more work to continually re-balance the camera while shooting.
A pure electronic housing will have all the camera functions activated via electronic pushbutton/slide controls. Like the Amphibico EVO or L&M Bluefin. Or the TopDawg.
btw, I know someone who shoots an HC1 in an Ikelite housing with excellent results.
