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 Panasonic ZS1 and Samsung HZ30W side-by-side from the front, back and top in their relative dimensions. Panasonic ZS1 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Samsung HZ30W has external dimensions of 107 x 61 x 28 mm (4.21 x 2.4 x 1.1″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries).
Below you can see the front view size comparison of Panasonic ZS1 and Samsung HZ30W. Panasonic ZS1 is 4mm narrower and 1mm shorter than Samsung HZ30W but it is also 5mm thicker.
Here is the back view size comparison of Panasonic ZS1 and Samsung HZ30W.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS1 is 16g lighter than the Samsung HZ30W but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Samsung HZ30W (WB600) 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
LCD Screen Size and Features
Samsung HZ30W's 3" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
