: You can only scale down (in format size) not up because of the very

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?
