talking abt the SX20, really find it out of point, it's basically a clone of the SX10 plus minus minor differences and 2 extra megapixel, HD video (1280 x 720) but not Full HD (SX1 1920 x 1080) :dunno:
:thumbsd: to Canon for releasing the SX20 which basically replaces the SX10 rather than release a firmware upgrade for the SX10
I've tried successfully on plants as well, but not on human, since the smaller sensor of a prosumer compare to DSLR, will not able to produce bokeh, unless your subject very close to your camera (lens), and the back ground very far away, which is when the macro mode (shooting plants).
