I have a suggestion, if you want to take the back ground out when you shooting close up flower, mostly you will use wide open aperture to blur the back ground, but it will limit the DOF, so the flower will look soft in some part. For my flower shooting, I always use out board flash with defuser, set the camera on manual mode with aperture from f11-f22. This will darken the back ground and get the flower sharp in focus. Here's a sample, it not a very good shot but it shows how this work!
