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 Pentax RZ10 and Pentax RS1500 side-by-side from the front, back and top in their relative dimensions. Pentax RZ10 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). Pentax RS1500 has external dimensions of 114 x 58 x 28 mm (4.49 x 2.28 x 1.1″) and weighs 157 g (0.35 lb / 5.54 oz) (including batteries).

Here is the back view size comparison of the Pentax RZ10 and Pentax RS1500.
Now lets look at the top view comparison of Pentax RZ10 and Pentax RS1500.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax RS1500 is 21g lighter than the Pentax RZ10 but we don't think this will make a significant difference.
