I am somewhat new at macro photography, and was hoping for a few pointers. I recently upgraded to a Canon Rebel XSi (EOS 450D). I purchased the EF-S 60mm f/2.8 USM macro lens, which has a ratio 1:1.
I know that I can getter better magnification with extension tubes... but which should I get? How much distance do I need to have to get substantially better magnification? I was hoping for 3:1 or 2:1 at least.
Any ideas would be appreciated. Cost is an issue for me, but I'm not afraid to pay a bit more for something that simply works well.
