Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon SX70 HS and Sony H300 side-by-side from the front, back and top in their relative dimensions. Canon SX70 HS has external dimensions of 127 x 91 x 117 mm (5 x 3.58 x 4.61″) and weighs 608 g (1.34 lb / 21.45 oz) (including batteries). Sony H300 has external dimensions of 130 x 95 x 122 mm (5.1 x 3.74 x 4.81″) and weighs 590 g (1.30 lb / 20.81 oz) (including batteries).
Below you can see the front view size comparison of Canon SX70 HS and Sony H300. Canon SX70 HS is clearly the smaller of the two cameras. Its body is 3mm narrower, 4mm shorter and 5mm thinner than Sony H300.
Here is the back view size comparison of Canon SX70 HS and Sony H300.
Now lets look at the top view comparison of Canon SX70 HS and Sony H300.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony H300 is 18g lighter than the Canon SX70 HS but we don't think this will make a significant difference.
Unfortunately neither Canon PowerShot SX70 HS nor Sony Cyber-shot DSC-H300 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
Canon SX70 HS and Sony H300's LCD screens has the same diagonal size of 3".
On the other hand, Canon SX70 HS sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Sony H300's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to SX70 HS.
