Photography is all about capturing light on a photographic emulsion or electronic sensor. And as such the lens and film or sensor, are the most important components affecting image quality. Essentially, the camera itself is just a light-tight box with a shutter!You've seen the wonderful pictures from the rovers sent by NASA to Mars. All detailed and colourful. You might think that they're from some huge megapixel space-age techno-beast and you'd be surprised to hear that the sensor is a paltry 1 megapixel. Bigger pixels mean less noise which is always a good thing, but where NASA put all its money was into a very high quality lens. The results show it was worth it!A camera that allows you to change the lens will obviously give you the greatest flexibility to pick the appropriate lens for the situation. An ideal camera like this is the SLR. You can choose from super wideangle to super telephoto. Macro for close ups. Bellows for even closer close up. Attach it to a microscope. Attach it to a telescope.
