Thread: Prosumer Cam are full frame?

  1. #1

    Default Prosumer Cam are full frame?

    If DSLR 350, 20D are not full frame cam, what about prosumer cams eg G6, are they consider full frame cam?

    No, they have a even more larger FLM. >3 at least.

    Currently the full frame sensor size for Canon 5D is 36 x 24 mm.
    Sensor size for 20D is 22.5 x 15.0mm, therefore it is 1.6x crop
    Sensor size for G6 is 7.18 x 5.32 mm, therefore its cropping is around 4.5 to 5x.

    Doesn't really matter for prosumer cams... cos their in-built lens are engineered for the sensor right?...

    Full frame or not is in the size of the sensor in relation to the "full" 35mm film frame (36mm x 24mm).

    For compact digicams, yes, the lenses are designed specifically for the size of the sensor used.

    For DSLRs, the reason why a "full frame sensor" is desired because anything less than full frame changes the field of view what film SLR users are so used too. For example, what used to be wide enough at 24mm is no longer as wide on non full-frame DSLRs because of the crop factor.

    But why the view on a 35mm compact digicam is wider than a 35mm on DSLR? Is it not 'full frame'.

    there is no "35mm" compact digicam. e.g the Canon G6 uses a 7.3mm to 28.8mm lens.

    1st...wat dslr are u refering to....unless using full frame dslr if not all will have 1.3 to 1.6 crop factor....so 35mm looks like 56mm on 20D.
    Bcoz compact cam are designed specially for the in built lens, so its easier to be designed to have a 35mm fov.
    Then y get a dslr since compact cam can have same fov and some compact have higher megapixel than a dslr?
    Even though a compact cam can have 8 or 10 mp, however they are built on a much tiny sensor compared to a dslr. Also means that a lot of pixel being squeezed into a tiny space. Overlapping of pixel may occur which will lead to lose of picture quality. Also becase of their small size, they allow much lesser light to pass through compared to a dslr sensor which have larger pixel, which also leads to lousier image quality.
    Many ppl thot that having high mp means everything, means that their cam are better than those thousands dollar dslr.

    Quantity doesnt mean quality.

    It is not.

    If you are talking about the 35mm equivalent Field of View (FOV) for both the compact digicam and the DSLR, they are the same. How can it be wider for the compact digicam when they have the same equivalent FOV?

    However, their focal length may be different, and quite likely the (absolute) focal length for the compact digicam to produce a 35mm equivalent FOV is shorter than for the DSLR.

    Focal length is measured in mm, and is the distance between the sensor and the lens aperture.

    Field of View is an angle, should strictly be measured in degrees. It is the angle of coverage for a certain lens. Before digital cameras, most standard photography is done on 35mm film, and there is a certain correlation between the focal length and the FOV. People will have a general idea of how wide or narrow a certain view is based on the focal length of the lens.

    Now with digital photography, and wildly varying sensor sizes, focal length and FOV do not have a direct correlation except when converted to the "35mm equivalent", since there is a 3rd variable of sensor size.
