egg, auto focus to me it is quite decent, as a point-n-shoot.  yeah optical zoom is the only thing I wish can be more, but like Ben said, nothing is perfect.  The picture quality is impressive enough for me to give up the zoom.

I am thinking as same as Mickey.  Auto focus picks up fast, f1.8, big number of ISO then I think is good enough.

Mickey, can your R100 remote to take pic from your smartphone?

咁我部HX9V 暫時都夠用, 仲要係16X ..

16 X zoom....video/image still clear with no noise?

egg, I compared video quality with hx7v and the one from rx100 is obviously better, especially in low light evvironment.

Ben, but it's for your parent?  maybe the zoom is more important to them woh

opticla OK 正常呀!! 基本上我係唔會用 digital zoom

咁RX100 點都新過7V, 如果差過就唔好啦

駁大霧, 當我係另一 department 嘅人, 順手加多啲 access right
