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

Unfortunately neither Olympus Stylus SP-100 nor Panasonic Lumix DMC-FZ1000 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
Olympus SP-100 and Panasonic FZ1000's LCD screens has the same diagonal size of 3.00".
On the other hand, Panasonic FZ1000 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. Olympus SP-100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ1000.
