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 Canon SX210 IS 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). Canon SX210 IS has external dimensions of 103 x 61 x 38 mm (4.06 x 2.4 x 1.5″) and weighs 220 g (0.49 lb / 7.76 oz) (including batteries).
Below you can see the front view size comparison of Panasonic ZS1 and Canon SX210 IS. Panasonic ZS1 has the same height with Canon SX210 IS. On the other hand, with a width of 60mm, it is 1 narrower and also with a thickness of 33mm, it is 5mm thinner than Canon SX210 IS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX210 IS is 9g lighter than the Panasonic ZS1 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Canon PowerShot SX210 IS 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
Canon SX210 IS'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.
