    Is liveview as mentioned in 40D specs really a tempting feature or you all guys feel ok to peep through the viewfinder while composing? Is this available normally in DSLR like it is in Point and shoots ?

    Live view on dSLR is fairly uncommon but is becoming more widely available. Why somebody would want to use the screen at the back of a dSLR to compose a shot is hard to understand? Trying to hold a fairly heavy dSLR steady while composing a shot by looking at the LCD screen must be very difficult.
     
  3. It's quite nice for a lot of types of shooting, esp. architecture and landscape when your camera is mounted on a tripod anyway. It's a much better way of composing a shot.

    Doing candid work like photo-journalism or street photography does not benefit from Live View.

    Yeah, the live view could be very useful for certain areas, as stated.
    I'd find it very useful for macro, being able to zoom in with live view to check you have pin point focus, which I just can't do with the viewfinder.
    So I'd find it very useful for certain types of photography.

    Live View will probably hardly be used on this camera, unless you cant look through the viewfinder. Cameras that do have this feature use more batter when it is on and have a delay when shooting since it is probably going to shoot with a dual-sensor. when you turn live view on, it moves an LCD sensor in front and blocks the main CCD and when you take a picture moves the LCD out of the way, re composses the main CCD and THEN takes your picture. It can be a second to a half to do this and take a picture.
     
  6. Yes, you're right. My understanding is that LiveView adds time to the shot, as the mirror needs to get out of the way for the shot.

    But for some shots (like the aforementioned macro, landscape, and architecture) the half second is not an issue.

    Live view mode will move the mirror up for viewing (flipping it down for AF)...but will that really add time to the shutter lag? If it's programmed well, the mirror won't need to be flipped down, so actually the shutter lag could, technically, be faster...couldn't it?
     
  8. You'd think that, wouldn't you?

    But on some of the Olympus and Leica dSLRs that have LiveView, the result is shutter lag.

    Maybe the mirror has to be down for metering?

    Liveview and long shutter lag...might as well be a $300 digicam. :lol: I'm more excited about the larger magnification on the viewfinder of the 40D.
     
  10. LOL, yeah.

    No, I think we're assuming that the sensor that records the image is the same that produces the image being reproduced during Live View. It's probably a different (smaller) sensor, otherwise the CCD would get too hot if charged that long, and create too much noise.

    I've just changed from a prosumer, KM A200, which had Live View but with an articulated LCD. Personally I think that a fixed LCD limits much of its usefulness.

    Also when I moved to DSLR I though Live View would be the biggest thing I would miss from the prosumer, in reality I haven't really missed it at all

    The thing you'll miss most with liveview is your battery life. I doubt you could run around all day without turning you camera off and take 400 photos on one set of batteries if you use the LCD to compose your shots.

    The viewfinder also gives you incentive to hold the camera properly and in a way which reduces possible image shake. I cringe to see people grab their P&S and hold them at arms lengths in low-light situations :S
