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 Samsung GX-1S and Samsung GX-1L side-by-side from the front, back and top in their relative dimensions. Samsung GX-1S has external dimensions of 125 x 93 x 66 mm (4.92 x 3.66 x 2.6″) and weighs 605 g (1.33 lb / 21.34 oz) (including batteries). Samsung GX-1L has external dimensions of 125 x 93 x 66 mm (4.92 x 3.66 x 2.6″) and weighs 570 g (1.26 lb / 20.11 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung GX-1S and the Samsung GX-1L. In this case, we can see that Samsung GX-1S and Samsung GX-1L have the exact same height, width and thickness.
Here is the back view size comparison of the Samsung GX-1S and Samsung GX-1L.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung GX-1L is 35g lighter than the Samsung GX-1S but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Samsung GX-1S and Samsung GX-1L have the same Pentax KAF lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Samsung GX-1S nor Samsung GX-1L 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 DSLR Cameras with Weather Sealing
LCD Screen Size and Features
Samsung GX-1S and Samsung GX-1L's LCD screens have the same diagonal size of 2.50 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
