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 Samsung TL225 and Panasonic GH4 side-by-side from the front, back and top in their relative dimensions. Samsung TL225 has external dimensions of 100 x 60 x 19 mm (3.94 x 2.36 x 0.75″) and weighs 187 g (0.41 lb / 6.60 oz) (including batteries). Panasonic GH4 has external dimensions of 133 x 93 x 84 mm (5.24 x 3.66 x 3.31″) and weighs 560 g (1.23 lb / 19.75 oz) (including batteries).
Below you can see the front view size comparison of Samsung TL225 and Panasonic GH4. Samsung TL225 is clearly the smaller of the two cameras. Its body is 33mm narrower, 33mm shorter and 65mm thinner than Panasonic GH4. As you can tell, actually this is not a fair size comparison since Samsung TL225 has a built-in lens but Panasonic GH4 doesn't. Once you put a lens on GH4, its thickness will increase significantly.
Here is the back view size comparison of Samsung TL225 and Panasonic GH4.
Now lets look at the top view comparison of Samsung TL225 and Panasonic GH4.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung TL225 is significantly lighter (373g ) than the Panasonic GH4 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 GH4, the total kit will weigh much higher.
Thanks to the weather sealed body of GH4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to TL225.
LCD Screen Size and Features
Samsung TL225's 3.5" LCD screen is slightly larger than Panasonic GH4's 3" screen.
On the other hand, Panasonic GH4 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. On the other hand, Samsung TL225 has a fixed type screen which provides almost no flexibility in shooting positions compared to GH4.
