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 FZ1000 and Pentax RZ18 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ1000 has external dimensions of 137 x 99 x 131 mm (5.39 x 3.9 x 5.16″) and weighs 831 g (1.83 lb / 29.31 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 FZ1000 and the Pentax RZ18. Pentax RZ18 is clearly the smaller of the two cameras. Its body is 40mm narrower, 38mm shorter and 98mm thinner than Panasonic FZ1000.
Here is the back view size comparison of the Panasonic FZ1000 and Pentax RZ18.
Now lets look at the top view comparison of Panasonic FZ1000 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 significantly lighter (653g ) than the Panasonic FZ1000 which may become a big advantage especially on long walking trips.
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 FZ1000.
LCD Screen Size and Features
Panasonic FZ1000 and Pentax RZ18's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic FZ1000 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Pentax RZ18's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ1000.
