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 Leica D-LUX 5 and Pentax P80 side-by-side from the front, back and top in their relative dimensions. Leica D-LUX 5 has external dimensions of 110 x 66 x 43 mm (4.33 x 2.6 x 1.69″) and weighs 271 g (0.60 lb / 9.56 oz) (including batteries). Pentax P80 has external dimensions of 102 x 59 x 25 mm (4.02 x 2.32 x 0.98″) and weighs 125 g (0.28 lb / 4.41 oz) (including batteries).
Below you can see the front-view size comparison of the Leica D-LUX 5 and the Pentax P80. Pentax P80 is clearly the smaller of the two cameras. Its body is 8mm narrower, 7mm shorter and 18mm thinner than Leica D-LUX 5.
Here is the back view size comparison of the Leica D-LUX 5 and Pentax P80.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax P80 is significantly lighter (146g ) than the Leica D-LUX 5 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Leica D-LUX 5 nor Pentax Optio P80 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
Leica D-LUX 5's 3.00" LCD screen is slightly larger than Pentax P80's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
