    Hey guys,
    ok on the lens of the Nokia 7610 and 6670 it says:
    3.7mm 1:2.8

    So is this a wide angle lens or the regular 50mm?
    If its wide angle, the pics dont appear wide.

    And on here are the camera specs of the new Nokia 6630:
    Focal length: 4.5mm (35mm equivalent 37mm)
    Focas distance of: 40cm to infinity
    F number/aperture: f/3.2
    Sensor Type: CMOS 1.3 megapixel

    My question here is, the same thing as above. And if the Aperture is set as f/3.2 and cannot change, then how can the camera automatically adjust it?

    That might just be the minimum aperture value. Very likely it is fixed though, in which case your telephone would just adjust the shutter speed to get the correct exposure. It's hard to judge how wide 3.7mm is on the sensor in that telephone, because there is no indication of how big the sensor is. Probably it's comparable to the other one in 35mm terminology though; somewhere around 28-35mm in length.

    Are you shopping for a new telephone to take photographs with?

    It's not wide angle, as Walter quite correctly says, it's approximately the same kind of image as you get with a fixed compact camera, so about 28mm equiv. As far as I know, all the Nokia camera phones are fixed aperture variable exposure; and all produce, quite frankly, dreadful images.
