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

Unfortunately neither Sony Cyber-shot DSC-HX90V nor Nikon Coolpix S810c provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon S810c's 3.7" LCD screen is slightly larger than Sony HX90V's 3" screen.
On the other hand, Sony HX90V LCD screen 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, Nikon S810c has a fixed type screen which provides less flexibility in shooting positions compared to HX90V.
