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 MX-1 and Ricoh PX side-by-side from the front, back and top in their relative dimensions. Pentax MX-1 has external dimensions of 122 x 61 x 51 mm (4.8 x 2.4 x 2.01″) and weighs 391 g (0.86 lb / 13.79 oz) (including batteries). Ricoh PX has external dimensions of 100 x 55 x 21 mm (3.94 x 2.17 x 0.83″) and weighs 156 g (0.34 lb / 5.50 oz) (including batteries).

Here is the back view size comparison of the Pentax MX-1 and Ricoh PX.
Now lets look at the top view comparison of Pentax MX-1 and Ricoh PX.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh PX is significantly lighter (235g ) than the Pentax MX-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the PX, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the MX-1.
LCD Screen Size and Features
Pentax MX-1's 3.00" LCD screen is slightly larger than Ricoh PX's 2.7" screen.
In addition to the size advantage, Pentax MX-1 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Ricoh PX has a fixed type screen which provides less flexibility in shooting positions compared to MX-1.
