----- Original Message ----- From: "Bob Talbot" : You can only scale down (in format size) not up because of the very : real limitation of the size of the image circle formed by a lens. poo! You're limiting your creativity Bob : A Canon EOS lens designed for film (allows the wave portion of light : through) has an image circle that covers the 35mm frame. <blah blah.. clipped> (secret, don't tell anyone.. but when you slap a 50mm designed for 35mm work with only a 44-56mm image circle on an 8x10 and use it as a close-up/macro lens shooting at say 4mm from a subject, the size of that circle becomes huge! nowt like a 10:1 macro! :-) : A "digital" lens however (designed to allow only the particulate : component of light to pass) is not constrained by the same laws of : physics, only the laws of the marketplace. like a rolling pin? : Go buy your iPod. Concentrate on taking photos and sharing them. : Learn that it is the sharing that really counts after all. I'd love to share but I don't know how to connect it to my computer <throws self on back waving arms and legs ineffectually in the air> Can you tell me how to do it? k
