Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Olympus FE-4000 and Pentax MX-1 side-by-side from the front, back and top in their relative dimensions. Olympus FE-4000 has external dimensions of 95 x 57 x 22 mm (3.74 x 2.24 x 0.87″) and weighs 136 g (0.30 lb / 4.80 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 Olympus FE-4000 and Pentax MX-1. Olympus FE-4000 is clearly the smaller of the two cameras. Its body is 27mm narrower, 4mm shorter and 29mm thinner than Pentax MX-1.
Here is the back view size comparison of Olympus FE-4000 and Pentax MX-1.
Now lets look at the top view comparison of Olympus FE-4000 and Pentax MX-1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus FE-4000 is significantly lighter (255g ) than the Pentax MX-1 which may become a big advantage especially on long walking trips.
Unfortunately neither Olympus FE-4000 (X-925) nor Pentax MX-1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Pentax MX-1's 3" LCD screen is slightly larger than Olympus FE-4000'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, Olympus FE-4000 has a fixed type screen which provides less flexibility in shooting positions compared to MX-1.
