So, I'm not really sure exactly what macro gives you. I know you can be closer to the subject, and that it magnifies it bigger, etc. I guess it boils down to this: Lets say I have 3 lenses and I shoot the same subject from the same distance. A 135mm, a 135mm macro, and a 200mm (or something similar). I'm assuming the subject would be "bigger" in the macro and 200mm (or 300mm, or whatever example you want), but would anything else be different? Could a 200mm (300mm, whatever), be used in place of the macro and get the same results with some cropping? Assuming I didn't need to be 10 cm away from the subject or something. Thanks.
