    Default How to read if a video camcorder lens is wide or tele?

    one problem I had with my HD700 camcorder is the lens records a rather narrow area (ie the lens is quite 'tele')

    I do not want my replacement model to have same issue, but the model I keen on is another newer xacti which I might not be able to gets a 'hands on' in S'pore since this model in mind is not widely available here.

    This is the lens spec for the old HD700 i having:
    6.3 – 31.7 mm (38 - 190 mm on a 35 mm camera), 5x optical zoom lens, Open f/3.5 (W) – 4.7 (T)

    This is the lens spec for the newer model i considering:
    30x optical zoom lens; Aperture: F=1.8(W) – 4.3(T)
    Focus distance: f=2.5 to 75.0mm;
    Photos: f=43-1290mm(=35mm) Optical 30x zoom
    Videos: f=43-1290mm(=35mm) Optical 30x zoom

    How to tell the lens coverage at the most "wide" mode?

    Thks in adv..

    The specs are given, you just need to read. The values for 35mm give a very clear indication. 43mm is not as wide as 38mm (35mm equivalent).

    Wikipedia helps: http://en.wikipedia.org/wiki/35_mm_e...t_focal_length
    The 35 mm effective focal length of a particular lens-sensor combination is the focal length that one would need for a 35 mm film camera to obtain the same angle of view.
    Which means: the 35 equivalent values is the only way to compare lenses and sensors of different systems as your video camera or Point and Shoot cameras.
    On 35mm film a lens with 50mm is considered a "normal lens" - the image reflects roughly what you see with naked eye. Everything smaller than 50mm is wide angle - you'll see a wider angle / wider field of view than normal, the objects appears to be further away. Everything above 50mm is telephoto - the field ob view is smaller, the objects appear to come closer.
    Angle of View: http://en.wikipedia.org/wiki/Angle_of_view (scroll down for some example images)
    Hope that helps
