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 LX5 and Samsung SL720 side-by-side from the front, back and top in their relative dimensions. Panasonic LX5 has external dimensions of 110 x 65 x 43 mm (4.33 x 2.56 x 1.69″) and weighs 271 g (0.60 lb / 9.56 oz) (including batteries). Samsung SL720 has external dimensions of 92 x 61 x 23 mm (3.62 x 2.4 x 0.91″) and weighs 168 g (0.37 lb / 5.93 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LX5 and the Samsung SL720. Samsung SL720 is clearly the smaller of the two cameras. Its body is 18mm narrower, 4mm shorter and 20mm thinner than Panasonic LX5.
Here is the back view size comparison of the Panasonic LX5 and Samsung SL720.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung SL720 is significantly lighter (103g ) than the Panasonic LX5 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX5 nor Samsung SL720 (PL70) 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 LX5's 3.00" LCD screen is slightly larger than Samsung SL720's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
