Macro with EF 100mm f/2.8L. First time.
I just picked up this lens earlier in the week. I haven't had any time to test it in a practical manner but just after a couple test shots, I'm very excited to put it to use. I didn't buy it for the Macro feature, I bought it as a portrait lens. Looking at your shots though, I can see myself delving into the Macro area soon enough. Great shots!
