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 E85 and Fujifilm A150 side-by-side from the front, back and top in their relative dimensions. 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). Fujifilm A150 has external dimensions of 92 x 61 x 22 mm (3.62 x 2.4 x 0.87″) and weighs 130 g (0.29 lb / 4.59 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax E85 and the Fujifilm A150. Fujifilm A150 is 1mm narrower and 2mm thinner than Pentax E85 but it is also 3mm taller.
Here is the back view size comparison of the Pentax E85 and Fujifilm A150.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm A150 is 15g lighter than the Pentax E85 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Pentax Optio E85 nor Fujifilm FinePix A150 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
Fujifilm A150's 3.00" LCD screen is slightly larger than Pentax E85's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
