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 Ricoh PX and Pentax MX-1 side-by-side from the front, back and top in their relative dimensions. 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). 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).
Below you can see the front-view size comparison of the Ricoh PX and the Pentax MX-1. Ricoh PX is clearly the smaller of the two cameras. Its body is 22mm narrower, 6mm shorter and 30mm thinner than Pentax MX-1.
Here is the back view size comparison of the Ricoh PX and Pentax MX-1.
Now lets look at the top view comparison of Ricoh PX and Pentax MX-1.
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
With its weather-sealed body, we believe that the PX has a big advantage over the MX-1 which doesn't provide any kind of environmental sealing.
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.
