Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Sony HX90V and Sony RX100 side-by-side from the front, back and top in their relative dimensions. Sony HX90V has external dimensions of 102 x 58 x 36 mm (4.02 x 2.28 x 1.42″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries). Sony RX100 has external dimensions of 102 x 58 x 36 mm (4 x 2.29 x 1.41″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony RX100 is 5g lighter than the Sony HX90V but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX90V nor Sony Cyber-shot DSC-RX100 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 HX90V and Sony RX100's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony HX90V 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 HX90V.
