Fun with close-ups

Made my first craigslist purchase today - a shiny used macro lens. I've read good things about the Tamron 90mm f/2.8. One popped up on craigslist and I jumped on it. I've never had a true macro before. The crazy thing focuses right up to within an inch or so, and at 90mm things are pretty close. I'm still working on technique. It's quite difficult to control camera shake when focused that close. So far, though, the lens seems to be very sharp and has a lovely bokeh. Should be a great portrait lens as well.
