okay so I have 2 noob lens questions :
1) how do I calculate how far is the closest object is at infinity focus? So as an example, I have the oly 17mm prime, if I were to focus at infinity, what's the closest object that would actually be in sharp focus?
2) What is a macro lens? I've read the google results and I'm still confused. It's easy to say "it's 1:1 size" but I don't understand what the difference between a macro and telephoto lens is. 2 examples :
a) if I get a 200mm lens, and I point it at something "close by" like say some thing in the same room as me, won't I get a life-size (1:1) image of that item anyways? Or conversely if I used a macro lens and just walked away from an item, it won't be 1:1 anymore, it'll be smaller, like any other lens...
b) if I get a 50mm macro lens, and I get a 50mm prime (or a zoom lens set to 50mm) and I take a picture of something, what's the difference in the picture I actually get? (Sure I could just try it, but that would entail me buying a bunch of lenses I don't understand.)
Hey I did say these were noob question okay...
