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 Panasonic FZ40 and Olympus 1 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ40 has external dimensions of 120 x 80 x 92 mm (4.72 x 3.15 x 3.62″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries). Olympus 1 has external dimensions of 116 x 87 x 57 mm (4.57 x 3.43 x 2.24″) and weighs 402 g (0.89 lb / 14.18 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FZ40 and the Olympus 1. Olympus 1 is 4mm narrower and 35mm thinner than Panasonic FZ40 but it is also 7mm taller.
Here is the back view size comparison of the Panasonic FZ40 and Olympus 1.
Now lets look at the top view comparison of Panasonic FZ40 and Olympus 1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 1 is significantly lighter (92g ) than the Panasonic FZ40 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FZ40 (Lumix DMC-FZ45) nor Olympus Stylus 1 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
Panasonic FZ40 and Olympus 1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus 1 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Panasonic FZ40 has a fixed type screen which provides less flexibility in shooting positions compared to 1.
