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.

It's already being used. wifi, live view and a small laptop. People are already publishing pictures taken in this way. There's a link in the second post in this thread to an example of it being used. So it does exist.

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.

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.

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 think I am starting to get this... after rereading Gordons post and following the linky.

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.

Yup, exactly. Sounds useful to me. You can also connect to it via wifi if you have the transmitter on the body. So theoretically you could place the camera in China with a computer that's running remote desktop and trigger it from your couch.

I've said it before and I'll say it again. Live view is more or less useless unless it's a swivel screen. If you can see the back of the camera, then you should be able to look through the viewfinder

but a screen that doesnt rotate is still better at composing photos above heads and crowds than an optical viewfinder that your eyes cant see through. mind you, lcd screens usually have a fairly generous viewing angle allowed.

it's an added convenience - not something forced upon the user.
when audio (as with photography's visual) went digital, i embraced the added conveniences as well.

Atropos, I agree that a swivel screen would made live view better. But it certainly isn't useless without it. I believe Olympus's first live view camera had a swivel screen, but they have stopped that. One has to wonder if they had a good reason to do so.

When I first "graduated" from my prosumer KM 7i, to the 7d, I missed the live view so much I didn't know how I would live without it. How great it was to actually see the exposure and make adjustments before taking the photo. Soon, I didn't miss it. Now I have live view on my FujiFilm S5 Pro.
I have yet to use it. One thing I still miss terribly about the 7i was the way the viewfinder would flip up so when I was on the ground taking photos, I could do it looking down into the viewfinder rather than putting my cheek on the dirt to look through it. I think my next investment for my S5 will be the right angle viewfinder attachment.

I've said it before and I'll say it again. Live view is more or less useless unless it's a swivel screen. If you can see the back of the camera, then you should be able to look through the viewfinder (and get a much clearer image with which to focus).

I can't imagine taking photos with the camera at arm's length except in exceptional circumstances. However, when I shoot on a tripod I really miss live view. My back just can't take all the bending over the camera to see what I'm doing. It was bad enough when I was using the screen to compose, but I hate the extra bending to reach the viewfinder. And on the rare occasions when I have to use manual focus, I imaging live view would be a big help with the extra magnification it offers.

splain this one to me... through the lens is through the lens (off the mirror) what is Live View? What the Camera sees has to be recorded by something then xmitted through the system and then displayed on the LCD. Nothing more than EVF on the peashooters with inherent EVF lag...

Live view is the mirror locked up and capturing through the lens off the sensor, from what I remember reading. So it requires MLU and the viewfinder will be dark.

The only thing I STILL miss from my previous point & shoot Canons is the swivel screen.

Live view on a screen that you can angle any which way is such a blessing!!! I don't like crawling on my belly to get certain shots, so I just used to twist the screen up and voila! Also brilliant for shooting over the heads of crowds.

The 40D's screen sadly doesn't move, but I'm hoping that the viewing angle will be wide enough to make the live view useful. If that's the case, then you'll learn to love it for certain shots, I'm sure. For the rest of the time simply turn it off.

Buy a cheap DVD player, plug the camera in to that. Sure it isn't wi-fi but how far away do you really need to be ? :) You can get about a 7" review screen for your camera for about $70. If you had live view, that's a 7" in field live preview screen you can view at any angle you like. I got fed up crawling around on the ground trying to line up macro shots and this would be really useful.

Either that or plug in the wi-fi adapter and connect from a laptop.
