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 NX300M and Sony A7c side-by-side from the front, back and top in their relative dimensions. Samsung NX300M has external dimensions of 122 x 64 x 41 mm (4.8 x 2.52 x 1.61″) and weighs 331 g (0.73 lb / 11.68 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).
Below you can see the front-view size comparison of the Samsung NX300M and the Sony A7c. Samsung NX300M is clearly the smaller of the two cameras. Its body is 2mm narrower, 7mm shorter and 19mm thinner than Sony A7c.
Now lets look at the top view comparison of Samsung NX300M and Sony A7c.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX300M is significantly lighter (178g ) 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 also have to take into account the lenses that you will be using with these bodies. Since Sony A7c has a Full frame sensor and Samsung NX300M has a smaller APS-C sensor, Samsung NX300M's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7c lenses.
Weather Sealing
Thanks to the weather-sealed body of the A7c, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the NX300M.
LCD Screen Size and Features
Samsung NX300M's 3.30" LCD screen is slightly larger than Sony A7c's 3″ screen.
