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 Olympus SP-610UZ and Pentax MX-1 side-by-side from the front, back and top in their relative dimensions. Olympus SP-610UZ has external dimensions of 107 x 73 x 73 mm (4.21 x 2.87 x 2.87″) and weighs 405 g (0.89 lb / 14.29 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 Olympus SP-610UZ and the Pentax MX-1. Pentax MX-1 is 12mm shorter and 22mm thinner than Olympus SP-610UZ but it is also 15mm wider.
Here is the back view size comparison of the Olympus SP-610UZ and Pentax MX-1.
Now lets look at the top view comparison of Olympus SP-610UZ and Pentax MX-1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax MX-1 is 14g lighter than the Olympus SP-610UZ but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SP-610UZ nor Pentax MX-1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Olympus SP-610UZ and Pentax MX-1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Pentax MX-1 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Olympus SP-610UZ has a fixed type screen which provides less flexibility in shooting positions compared to MX-1.
