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 Leica CL and Sigma fp side-by-side from the front, back and top in their relative dimensions. Leica CL has external dimensions of 131 x 78 x 45 mm (5.16 x 3.07 x 1.77″) and weighs 403 g (0.89 lb / 14.22 oz) (including batteries). Sigma fp has external dimensions of 113 x 70 x 45 mm (4.45 x 2.76 x 1.77″) and weighs 422 g (0.93 lb / 14.89 oz) (including batteries).
Below you can see the front-view size comparison of the Leica CL and the Sigma fp. Sigma fp is 18mm narrower and 8mm shorter than Leica CL but they have the same thickness of 45mm.
Here is the back view size comparison of the Leica CL and Sigma fp.
Now lets look at the top view comparison of Leica CL and Sigma fp.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica CL is 19g lighter than the Sigma fp 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 Sigma fp has a Full frame sensor and Leica CL has a smaller APS-C sensor, Leica CL's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sigma fp lenses.
Weather Sealing
Thanks to the weather-sealed body of the fp, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the CL.
LCD Screen Size and Features
Sigma fp's 3.20" LCD screen is slightly larger than Leica CL's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
