Nice shots DK. I have the 50mm f2 and I find it to be a superb lens. Being a pro lens, it is dust and splash proof, but expensive. As Hannah-Marie intimates she is on a budget, I think she should probably look at the Zuiko 35mm macro. I have not used this myself, but users seem to be more than pleased with it. It is also 1:1 macro as opposed to 2:1 macro in the case of the 50mm f2.
