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 Kodak M550 and Pentax Efina side-by-side from the front, back and top in their relative dimensions. Kodak M550 has external dimensions of 98 x 58 x 23 mm (3.86 x 2.28 x 0.91″) and weighs 125 g (0.28 lb / 4.41 oz) (including batteries). Pentax Efina has external dimensions of 87 x 54 x 21 mm (3.43 x 2.13 x 0.83″) and weighs 91 g (0.20 lb / 3.21 oz) (including batteries).
Below you can see the front-view size comparison of the Kodak M550 and the Pentax Efina. Pentax Efina is clearly the smaller of the two cameras. Its body is 11mm narrower, 4mm shorter and 2mm thinner than Kodak M550.
Here is the back view size comparison of the Kodak M550 and Pentax Efina.
Now lets look at the top view comparison of Kodak M550 and Pentax Efina.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Efina is significantly lighter (34g ) than the Kodak M550 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Kodak EasyShare M550 nor Pentax Efina 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
Kodak M550's 2.70" LCD screen is slightly larger than Pentax Efina's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
