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 Kodak M590 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). Kodak M590 has external dimensions of 97 x 58 x 15 mm (3.82 x 2.28 x 0.59″) and weighs (including batteries).
Below you can see the front view size comparison of Panasonic ZS3 and Kodak M590. Kodak M590 is clearly the smaller of the two cameras. Its body is 6mm narrower, 2mm shorter and 18mm thinner than Panasonic ZS3.
Here is the back view size comparison of Panasonic ZS3 and Kodak M590.
Now lets look at the top view comparison of Panasonic ZS3 and Kodak M590.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Kodak M590 is 229g 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 Kodak M590 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 Kodak M590's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
