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 LF1 and Sony W290 side-by-side from the front, back and top in their relative dimensions. Panasonic LF1 has external dimensions of 103 x 62 x 28 mm (4.06 x 2.44 x 1.1″) and weighs 192 g (0.42 lb / 6.77 oz) (including batteries). Sony W290 has external dimensions of 98 x 57 x 23 mm (3.86 x 2.24 x 0.91″) and weighs 167 g (0.37 lb / 5.89 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LF1 and the Sony W290. Sony W290 is clearly the smaller of the two cameras. Its body is 5mm narrower, 5mm shorter and 5mm thinner than Panasonic LF1.
Here is the back view size comparison of the Panasonic LF1 and Sony W290.
Now lets look at the top view comparison of Panasonic LF1 and Sony W290.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W290 is 25g lighter than the Panasonic LF1 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LF1 nor Sony Cyber-shot DSC-W290 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 LF1 and Sony W290's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
