Modern colour negative film resolves around 100 line pairs per mm image height, which boils down to the equivalent of 34 megapixels. Which is not what you get, because very many lenses even high end primes do not resolve more than 50 line pairs, which is equivalent to 9 megapixels. Cheap zoom lenses even only resolve 30 line pairs per mm, which would be 3 megapixels. Note: These are real megapixels. Calculating up and down interpolation success and loss, a 3 megpixel camera will resolve the equivalent of slightly over 2 megapixels (two thirds) as a rule of thumb. So, the EOS-1D is approximately what you get from state of the art colour negative film in combination to consumer class zoom lenses. The above calculations are taken from the current issue of c't magazine, Germany's most reputated computer magazine, which lately shows excellent expertise in photography. -- Michael Quack <[EMAIL PROTECTED]> * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
