Earlier this year I was searching for the "perfect" bike camera and it came down to a Canon Elph or the Sony T7. I ended up getting the T7 and unfortunately it was the wrong choice. The Sony is incredibly small and easily slips into the rear pocket of a cycling jersey. It takes great pictures but it doesn't have a view finder and outside on a sunny day it is very difficult to frame a picture using the LCD screen. Under the right conditions it's still a great camera but not outside on a sunny day.
So my suggestion is to make sure you get a camera with a viewfinder, it's worth the little extra size.
