Mark,
How do Sigma lenses compare wih Canon. Sigma has a 80-400mm image
stabilised zoom, how does it compare with the Canon 100-400 IS?
To what magnification can you hand-hold a camera without
significant shake and blurring? ie when do you need a tripod? Are monopods
any good?
How much magnification can you achieve by blowing up a digital
image from say a 6 megapixel camera and perfect exposure without losing good
definition?
Thanks
Michael
