Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 nor Canon PowerShot SX730 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony RX100 and Canon SX730 HS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon SX730 HS features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Sony RX100 has a fixed type screen which provides less flexibility in shooting positions compared to SX730 HS.
