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 Canon SX420 IS and Canon SX70 HS side-by-side from the front, back and top in their relative dimensions. Canon SX420 IS has external dimensions of 104 x 69 x 85 mm (4.09 x 2.72 x 3.35″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries).

Below you can see the front-view size comparison of the Canon SX420 IS and the Canon SX70 HS. Canon SX420 IS is clearly the smaller of the two cameras. Its body is 23mm narrower, 22mm shorter and 32mm thinner than Canon SX70 HS.
Here is the back view size comparison of the Canon SX420 IS and Canon SX70 HS.
Now lets look at the top view comparison of Canon SX420 IS and Canon SX70 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX420 IS is significantly lighter (283g ) than the Canon SX70 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot SX420 IS nor Canon PowerShot SX70 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 SX420 IS and Canon SX70 HS's LCD screens have the same diagonal size of 3.00 inches.
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. Canon SX420 IS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to SX70 HS.
