Weight is another important factor especially when deciding on a camera that you want to carry with you all day.

Unfortunately neither Canon PowerShot SX540 HS nor Panasonic Lumix DMC-FZ2500 (Lumix DMC-FZ2000) 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 SX540 HS and Panasonic FZ2500's LCD screens has the same diagonal size of 3.00".
On the other hand, Panasonic FZ2500 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 SX540 HS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ2500.
