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 Pentax RZ18 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). Pentax RZ18 has external dimensions of 97 x 61 x 33 mm (3.82 x 2.4 x 1.3″) and weighs 178 g (0.39 lb / 6.28 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LF1 and the Pentax RZ18. Pentax RZ18 is 6mm narrower and 1mm shorter than Panasonic LF1 but it is also 5mm thicker.
Here is the back view size comparison of the Panasonic LF1 and Pentax RZ18.
Now lets look at the top view comparison of Panasonic LF1 and Pentax RZ18.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax RZ18 is 14g lighter than the Panasonic LF1 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the RZ18, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the LF1.
LCD Screen Size and Features
Panasonic LF1 and Pentax RZ18'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.
