I've never had a lens with a macro function, but i'm thinking of buying one. My question is how do you use the feature? is it switch? a button?...?

here is the lens i want (http://www.amazon.com/gp/product/B000JDJJ82/ref=wl_it_dp/002-1695200-4644824?ie=UTF8&coliid=I13GPPYVGYPUD3&colid=32T02KAILIKSO) anyone have experience with it or advice they would like the share?

I am currently using the 17-70mm Macro. AFAIK, you just zoom in to 70mm and it will 'macro' the subject.
With the 18-50, I'm pretty sure its the same. You would have to go into 50mm and the lens will magnify the subject for you.

Some "standard" lens have macro features. This simply allows the lens
to be focused closer than usual. Some "macro" lens are designed just
for macro use and can't be focused except in close up mode. I have
have several lens with macro settings. Each works a little differently
but not complicated. On one you zoom to a point marked Macro and
focus as usual. Another has a seperate setting on the auto focus for
macro. In both cases and as with any SLR you can see the results as
you work. Both will focus in the auto & manual mode. Most real macro
lens are limited to fairly close work where the standard with macro
settings can be used as a regular lens but usually will not work as
close as the macro. Some have markings such as 1:1 or 2:1 etc.
If so these indicate how big the image will be on the film or digital
sensor as compared to real life. In other words a lens marked 1:1
would make an object 1/2 inches wide to register on the film or sensor
as 1/2 inches.
