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 SX150 IS and Canon SX50 HS side-by-side from the front, back and top in their relative dimensions. Canon SX150 IS has external dimensions of 113 x 73 x 46 mm (4.45 x 2.87 x 1.81″) and weighs 306 g (0.67 lb / 10.79 oz) (including batteries). Canon SX50 HS has external dimensions of 123 x 87 x 106 mm (4.84 x 3.43 x 4.17″) and weighs 595 g (1.31 lb / 20.99 oz) (including batteries).
Below you can see the front view size comparison of Canon SX150 IS and Canon SX50 HS. Canon SX150 IS is clearly the smaller of the two cameras. Its body is 10mm narrower, 14mm shorter and 60mm thinner than Canon SX50 HS.
Now lets look at the top view comparison of Canon SX150 IS and Canon SX50 HS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX150 IS is significantly lighter (289g ) than the Canon SX50 HS which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot SX150 IS nor Canon PowerShot SX50 HS 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 SX150 IS's 3" LCD screen is slightly larger than Canon SX50 HS's 2.8" screen.
On the other hand, Canon SX50 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. On the other hand, Canon SX150 IS has a fixed type screen which provides almost no flexibility in shooting positions compared to SX50 HS.
