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 ZS7 and Olympus TG-4 side-by-side from the front, back and top in their relative dimensions. 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). Olympus TG-4 has external dimensions of 112 x 66 x 31 mm (4.41 x 2.6 x 1.22″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries).

Now lets look at the top view comparison of Panasonic ZS7 and Olympus TG-4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS7 is 29g lighter than the Olympus TG-4 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TG-4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS7.
LCD Screen Size and Features
Panasonic ZS7 and Olympus TG-4's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
