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 TL220 and Pentax E70 side-by-side from the front, back and top in their relative dimensions. Samsung TL220 has external dimensions of 100 x 60 x 19 mm (3.94 x 2.36 x 0.75″) and weighs 169 g (0.37 lb / 5.96 oz) (including batteries). Pentax E70 has external dimensions of 94 x 61 x 26 mm (3.7 x 2.4 x 1.02″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung TL220 and the Pentax E70. Samsung TL220 is 1mm shorter and 7mm thinner than Pentax E70 but it is also 6mm wider.
Here is the back view size comparison of the Samsung TL220 and Pentax E70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung TL220 is 6g lighter than the Pentax E70 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung TL220 (ST500) nor Pentax Optio E70 provides any type of weather sealing in their bodies, 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
LCD Screen Size and Features
Samsung TL220's 3.00" LCD screen is slightly larger than Pentax E70's 2.4" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
