OK, I should be getting a Sony SLR in the near future (well Christmas to be precise,) And I have read, well, some pretty bad reviews on the 18-70mm kit lens (yes, I'm getting an a200.)

I've managed to save up 150, and have decided to spend it on a lens if I'm not pleased with the kit lens.

Now, I have two lenses in mind, and wondered which you think would best soot my needs...

I enjoy taking macro pictures, but yet I'm looking for a lens that would perform in low light well as well as producing sharp images...

my two options are:

Sony 50mm f1.8 portrait
or the
Sony 30mm f2.8 macro

Which would you recommend? as I don't want to throw 25 weeks worth of savings down the toilet!

Thanks in advance
