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 Samsung TL225 and Sony W610 side-by-side from the front, back and top in their relative dimensions. Samsung TL225 has external dimensions of 100 x 60 x 19 mm (3.94 x 2.36 x 0.75″) and weighs 187 g (0.41 lb / 6.60 oz) (including batteries). Sony W610 has external dimensions of 93 x 52 x 19 mm (3.66 x 2.05 x 0.75″) and weighs 113 g (0.25 lb / 3.99 oz) (including batteries).

Here is the back view size comparison of the Samsung TL225 and Sony W610.
Now lets look at the top view comparison of Samsung TL225 and Sony W610.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W610 is significantly lighter (74g ) than the Samsung TL225 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Samsung TL225 (ST550) nor Sony Cyber-shot DSC-W610 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
Samsung TL225's 3.50" LCD screen is slightly larger than Sony W610's 2.7" screen.
