The maximum resolution of HS9 is 7 or 5 hours. Sr 10 is similar to this. SD9, you need to prepare a lot of cards. . If you count the money in the card. Sd9 is not good, please.

In the case of sufficient light, hs9 is a little clearer than sr 10, which is better than Sr 1080, whether because of the imaging technology problems of ccd and cmos or the gap between 1080p and 1080i.

But ... I suggest you use sr 10. Sr 10 can add an external microphone. Hs9 can't. When Mike of hs9 was recording, the bathtub was a little high. I wonder if sr 10 plus Mike would be better? .

I use hs9 myself. There's only one problem with hs9, the microphone takes a bath.
