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 Ricoh GR III and Samsung NX1 side-by-side from the front, back and top in their relative dimensions. Ricoh GR III has external dimensions of 109 x 62 x 33 mm (4.29 x 2.44 x 1.3″) and weighs 257 g (0.57 lb / 9.07 oz) (including batteries). Samsung NX1 has external dimensions of 139 x 102 x 66 mm (5.47 x 4.02 x 2.6″) and weighs 550 g (1.21 lb / 19.40 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh GR III and the Samsung NX1. Ricoh GR III is clearly the smaller of the two cameras. Its body is 30mm narrower, 40mm shorter and 33mm thinner than Samsung NX1. As you can tell, actually this is not a fair size comparison since Ricoh GR III has a built-in lens but Samsung NX1 doesn't. Once you put a lens on NX1, its thickness will increase significantly.
Here is the back view size comparison of the Ricoh GR III and Samsung NX1.
Now lets look at the top view comparison of Ricoh GR III and Samsung NX1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh GR III is significantly lighter (293g ) than the Samsung NX1 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 NX1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the NX1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the GR III.
LCD Screen Size and Features
Ricoh GR III and Samsung NX1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Samsung NX1 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Ricoh GR III has a fixed type screen which provides less flexibility in shooting positions compared to NX1.
