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 ZS3 and Panasonic FZ150 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). Panasonic FZ150 has external dimensions of 124 x 82 x 92 mm (4.88 x 3.23 x 3.62″) and weighs 528 g (1.16 lb / 18.62 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS3 and the Panasonic FZ150. Panasonic ZS3 is clearly the smaller of the two cameras. Its body is 21mm narrower, 22mm shorter and 59mm thinner than Panasonic FZ150.
Here is the back view size comparison of the Panasonic ZS3 and Panasonic FZ150.
Now lets look at the top view comparison of Panasonic ZS3 and Panasonic FZ150.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS3 is significantly lighter (299g ) than the Panasonic FZ150 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) nor Panasonic Lumix DMC-FZ150 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic ZS3 and Panasonic FZ150's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic FZ150 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Panasonic ZS3's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to FZ150.
