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 ZS3 and Olympus FE-47 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS3 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). Olympus FE-47 has external dimensions of 98 x 61 x 27 mm (3.86 x 2.4 x 1.06″) and weighs 204 g (0.45 lb / 7.20 oz) (including batteries).
Below you can see the front view size comparison of Panasonic ZS3 and Olympus FE-47. Olympus FE-47 is 5mm narrower and 6mm thinner than Panasonic ZS3 but it is also 1mm taller.
Here is the back view size comparison of Panasonic ZS3 and Olympus FE-47.
Now lets look at the top view comparison of Panasonic ZS3 and Olympus FE-47.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus FE-47 is 25g lighter than the Panasonic ZS3 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Olympus FE-47 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
Panasonic ZS3's 3" LCD screen is slightly larger than Olympus FE-47's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
