Later on I'll take a shot with a 1:1 macro to give you some idea of what you'll get from one.
So in theory, if im taking a picture of something approx 15mm by 10mm in size, im not really going to need a macro lens?? Look forward to seeing the shot, thanks!

You're doing very, very well if you can get 1:1, almost anything more than that is very specialist. Also bear in mind that even at 1:1, your depth of field is going to be exceptionally shallow (1-2mm?) even at very small apertures. Read the glossary I pointed you to in the other "hello" thread if you don't understand what I'm talking about.
First comment is correct, thats not particuly practical or appealing as I want to keep my subjects alive.

So as a "short term" goal, I should perhaps aim at taing 1:1 or as close as possible, then maybe, depending on results try for higher.
Will go take at look in my hello thread, thanks!

Appreciate the info all.
