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 Panasonic 3D1 and Panasonic ZS7 side-by-side from the front, back and top in their relative dimensions. Panasonic 3D1 has external dimensions of 108 x 58 x 24 mm (4.25 x 2.28 x 0.94″) and weighs 193 g (0.43 lb / 6.81 oz) (including batteries). Panasonic ZS7 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic 3D1 and the Panasonic ZS7. Panasonic 3D1 is 2mm shorter and 9mm thinner than Panasonic ZS7 but it is also 5mm wider.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic 3D1 is 25g lighter than the Panasonic ZS7 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-3D1 nor Panasonic Lumix DMC-ZS7 (Lumix DMC-TZ10) 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
Panasonic 3D1's 3.50" LCD screen is slightly larger than Panasonic ZS7's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
