Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Samsung TL225 and Panasonic ZS20 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung TL225 is 19g lighter than the Panasonic ZS20 but we don't think this will make a significant difference.
Unfortunately neither Samsung TL225 (ST550) nor Panasonic Lumix DMC-ZS20 (Lumix DMC-TZ30) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
