Low Light, ok, that's a good reason. I'm yet to find any decent low light footage shot with the LX7, so it's hard to know. The only clip I've been able to find is this
Pretty badly shot, but doesn't look too bad. Dynamic range would probably be better with the RX100 too. I'm still undecided, but that 120fps option would be nice. If it were just used for a few random shots here and there, could easily be uprezzed to 1080P.
Your "what do I want to use it for, and how" makes perfect sense. Although to be honest, my only real requirement is a camera that can shoot video at 1080 50P minimum, with either manual control or some kind of exposure lock. Anything else would a bonus, so I thought it would be nice to get a few opinions here on what additional features others find most appealing. Which I appreciate, thanks! In fact, if Nokia announce a Pure View Windows Phone 8 device at the Microsoft conference next week, I might even consider that.
