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-W830 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
Canon SX730 HS's 3.00" LCD screen is slightly larger than Sony W830's 2.7" screen.
In addition to the size advantage, Canon SX730 HS LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Sony W830 has a fixed type screen which provides less flexibility in shooting positions compared to SX730 HS.
