Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax VS20 is significantly lighter (365g ) than the Canon SX40 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither Pentax Optio VS20 nor Canon PowerShot SX40 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
Pentax VS20's 3" LCD screen is slightly larger than Canon SX40 HS's 2.7" screen.
On the other hand, Canon SX40 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, Pentax VS20 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX40 HS.
