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 V-Lux 20 and Pentax Efina side-by-side from the front, back and top in their relative dimensions. Leica V-Lux 20 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). Pentax Efina has external dimensions of 87 x 54 x 21 mm (3.43 x 2.13 x 0.83″) and weighs 91 g (0.20 lb / 3.21 oz) (including batteries).
Below you can see the front-view size comparison of the Leica V-Lux 20 and the Pentax Efina. Pentax Efina is clearly the smaller of the two cameras. Its body is 16mm narrower, 6mm shorter and 12mm thinner than Leica V-Lux 20.
Here is the back view size comparison of the Leica V-Lux 20 and Pentax Efina.
Now lets look at the top view comparison of Leica V-Lux 20 and Pentax Efina.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Efina is significantly lighter (127g ) than the Leica V-Lux 20 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Leica V-Lux 20 nor Pentax Efina provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Leica V-Lux 20's 3.00" LCD screen is slightly larger than Pentax Efina's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
