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 TS2 and Panasonic GF2 side-by-side from the front, back and top in their relative dimensions. Panasonic TS2 has external dimensions of 99 x 63 x 24 mm (3.9 x 2.48 x 0.94″) and weighs 188 g (0.41 lb / 6.63 oz) (including batteries). Panasonic GF2 has external dimensions of 113 x 68 x 33 mm (4.45 x 2.68 x 1.3″) and weighs 310 g (0.68 lb / 10.93 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic TS2 and the Panasonic GF2. Panasonic TS2 is clearly the smaller of the two cameras. Its body is 14mm narrower, 5mm shorter and 9mm thinner than Panasonic GF2. As you can tell, actually this is not a fair size comparison since Panasonic TS2 has a built-in lens but Panasonic GF2 doesn't. Once you put a lens on GF2, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic TS2 and Panasonic GF2.
Now lets look at the top view comparison of Panasonic TS2 and Panasonic GF2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic TS2 is significantly lighter (122g ) than the Panasonic GF2 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on GF2, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the TS2, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the GF2.
LCD Screen Size and Features
Panasonic GF2's 3.00" LCD screen is slightly larger than Panasonic TS2's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
