How are you finding the RX100, especially coming from the canon 7D - are you satisfied with the quality, the fixed lens, and with it as a filmmaking tool
I'm very satisfied with image quality for the camera it is. Make no mistakes though, this is not a 7D, this is a fragile little camera, if the lens decides to get stuck there's probably not much I'll be able to do about it on the spot, It'd be risky to use it even on a small production if have a team depending on it. The built in lens is great, especially at 28mm since it goes to 1.8, but more limited in longer focal lengths.
The dealing with menus also feels more fiddly than dealing with Canon menus, there are more confirmation screens, consumer level alerts, it's not as "mechanical" and direct as with a Canon, and the buttons are tiny, and pressing a button will most likely cause the camera to move...
Also, I never felt the sturdiness of a Canon 7D. I had no problem shooting under rain or snow with the 7D, I wouldn't even risk it with the RX100. There's also something about the Canon image quality that you just don't get, even if you get slightly more resolution with the RX100.
But then again, these are all points that seemed obvious to me when I first got it, so no disappointment at all, it's an amazing pocket camera, and I'm thinking about shooting a small short with it, even considering all the risks.
