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 I-10 and Pentax E85 side-by-side from the front, back and top in their relative dimensions. Pentax I-10 has external dimensions of 101 x 65 x 28 mm (3.98 x 2.56 x 1.1″) and weighs 153 g (0.34 lb / 5.40 oz) (including batteries). Pentax E85 has external dimensions of 93 x 58 x 24 mm (3.66 x 2.28 x 0.94″) and weighs 145 g (0.32 lb / 5.11 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax I-10 and the Pentax E85. Pentax E85 is clearly the smaller of the two cameras. Its body is 8mm narrower, 7mm shorter and 4mm thinner than Pentax I-10.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax E85 is 8g lighter than the Pentax I-10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Pentax Optio I-10 nor Pentax Optio E85 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
Pentax I-10 and Pentax E85's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
