It sounds like it is a wireless (using ADHOC (computer to computer network)) version of EOS Capture (cam tethered to computer via USB and you take pics). You strategically place the camera somewhere you can't use the viewfinder, sit back at a pewter make your settings and capture the shot.

That's two distinct things really. The wireless bit isn't part of live view - you can do it wired/tethered or wireless.

I don't really think liveview is particularly well suited to using the LCD on the back of the camera though - it makes more sense with an external display (portable DVD player in the field, TV or computer in the studio) A swivel LCD is great, I had one on my Canon G2 a while ago, but I don't really get the feeling that this mode is designed for handholding, like it is with a P&S.

It can then be combined with EOS capture to do remote control with live update - either wireless or tethered again.

Yes, the sensor (CMOS in this case) would be active during live view. You are seeing what the sensor is "seeing" and therefore exactly the composition and focus you'll get when you hit that shutter button.

Wonder what noise effect this has if the sensor is sitting there cooking for 10 seconds before the shot is actually taken.

I can shoot 1-2 hour shots without any real noise build up at ISO 400. It'll have some effect but not much. 10 seconds would be nothing.

Mark II has live view?

I'm saying if you are gazing into the lcd for 10 seconds before every picture and the sensor is active, you are essentially taking 10+ second exposures all the time. Long exposures have a lot of noise and it is because the sensor is sitting there heating up for so long.

No, I'm saying I've taken 1 to 2 hour exposures, with very little noise build up. (slight blooming from the power supply points on the device) 5-10 minute exposures are totally clean. 10 second live view prior to an exposure would be nothing. that's with a MkII. The newer sensors have better thermal noise rejection.

I believe that what you want exists. Look over the specs on the WFT-E2 (I think that's the correct nomenclature. In conjunction with the 1DsMkIII, I believe this can remotely control some camera functions, including getting a live view. At least that's how I read the 1DsIII release.

If he wants what I want, I think it doesn't exist. I really miss the swivel LCD finder on a video cam or the swivel lens on my Sony.

It is almost impossible to do some angles/compositions with a DSLR, even with my angle-finder. A flexible, Wirelees, remote viewer would be really convenient in some situations.

Canon is finally taking some steps in the right direction.
