I've caught the bug to try to shoot snowflakes (in Wisconsin, we have plenty right now). Any advice on a macro lens? I have the kit 12-50, but it doesn't seem to get me close enough. The 60mm MZuiko is on sale right now - I'm thinking about that. Anything else to tempt me?? ( I also love to shoot bugs & flowers after the thaw, so I'm sure I'd get great use out of whatever I end up with) Thanks!
