I'd like to know how these new "digital" lenses work. Have you seen the rear elements of these new "digital" lens designs? If this is what they are doing the rear elements should be huge and set far from the sensor yes? ------------------------------------------------------------------------ --------------- Chip, >From discussions the elements in the lens direct the majority of light straight on as opposed to angled. Film is flat but the pixels on a sensor stick out a small fraction (each having a small encasement around it) so the light that comes at an angle does not provide as much as if the light were directed a bit straighter. Digital lenses designed for this compromise edge sharpness (less light) in favor of central sharpness (more light directed to the central area or smaller sensor) when used with film cameras. My friend with the new Tamron was surprised and wound up buying the Tamron 28-75mm lens XR Di and is selling the Nikkor. His colleague uses a 10D and is also looking to buy this lens. Very impressive results. When you enlarge the image you will see less artifacts with the Tamron than the Nikkor and at a street price of $330 for a F2.8 lens designed for digital, its a steal. (BTW, its surprisingly small too!)
