    Default Offset of optical finder and LCD

    WHen I use the Optical finder to take photo, I realise that the Image capture is different when I view it using the LCD.

    Why is that so?

    Anyone have this problem? Using Canon A20.

    Thanks.

    Wait.. Will post some pic I take.. but not very good :P

    This is my 1st DC..

    Well, IMHO,


    Pros
    1. Its got a good feel, not too light.
    2. Use AA battery, I dun like batter that can be used in ceratin manufacturer.
    3. Fast USB transfer.
    4. Not very expensive.
    5. Can use filter if you wanted.
    6. A 64 Mb CF can hold quite a lot of photos as I only develop in 4R.

    Cons
    1. Nite shot not good..
    2. The USB connector is enclosed using a rubber piece.. Dun think it will hold on long.3.Can really play much with manual setting.
    4. 8mb CF that come with it is nosense.. Will run of disk place soon. (maybe use it to transfer pic for develop)
    5. Think the optical finder is offset (or is it just me?)
    6. In darker environment, may have to hold the button longer to take a pic.


    P.s. My judgement may be inaccurate as I dun own any SLR or manual camera before... I take mainly "tourist" pics

    Almost all the digital cameras with a optical finder will have this problem. This is because the optical finder does not show you what's through the lens. It is a completely separate optical system itself. Since the lens and optical finder are on different planes, there is parallax error. This error is small for distant objects but can be quite significant for closer objects.

    CK, does it mean that even the DC is TTL and EVF, it only show up on the LCD but not on the optical viewfinder?

    Huh?

    If the DC has an EVF, then you won't get parallax error as it will be viewing through the lens. The way to test is, if you block the lens and can still see through the view finder, then the viewfinder is not viewing through the lens.

    Furthermore, the optical view finder will most likely not have 100% coverage of what the CCD captures. Most of the time optical view finders gives about 92 to 95% coverage. So you will end up caturing more than what you see in the optical view finder.
    As complexity rises, precise statements lose meaning and meaningful statements lose precision.

    for close-up shots, use the LCD to compose.
