I have a canon s500 and a80, what I do is set it to the macro feature (flower icon), do not zoom in whatsoever, just hold the camera very steady and close to the bud, then lightly push the button down but not all the way, the camera will then focus and you'll immediately see the effect of the macro, set it to the position you'd like it and then push the button the rest of the way to snap the photo. For best results turn off the flash and use natural light when grabbing some shots of your bud.
