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 Sigma fp and Sony A7c side-by-side from the front, back and top in their relative dimensions. 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). Sony A7c has external dimensions of 124 x 71 x 60 mm (4.88 x 2.8 x 2.36″) and weighs 509 g (1.12 lb / 17.95 oz) (including batteries).

Now lets look at the top view comparison of Sigma fp and Sony A7c.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sigma fp is significantly lighter (87g ) than the Sony A7c which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Sigma fp and Sony A7c have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Both fp and A7c have weather sealings in their body, making them resistant to water and dust.
