20d image size HELP
Can someone help a newbie out?
I have read in a few posts about different lenses only producting certain sized images on the DSLR's, something about 1.6 crop? Then reading a post from a guy wanting a wider angle because his 18mm canon lens only produces 20-something size.
Also reading about some new sigma lens, an 18-50mm I beleive thats popular because it produces an ACTUAL 18mm image???
Am I making sense, if so, what does all this mean.
If I am not making sense-sorry for trouble.
