Dusted off my L930 recently, put W10M on it. Although the Camera app has a lot of good sides I miss the 5MP+16/19MP option. I like having the oversampled 5MP image for sharing through social media and messaging apps and having the high res version uploaded to OneDrive. So I downloaded Lumia Camera Classic, and am loving it again. Lovely shutter sound, focus confirmation beep, less aggressive image processing and the important 5MP+16/19MP JPG option. It also seems to have less problems with focus. I could not get the above scene in focus with the W10M Camera app using autofocus, even while focusing on the exact same spot.
Anyway, if you are like me, it's worth having Lumia Camera Classic installed next to the normal Camera app.
