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 Fujifilm X-T1 IR and Ricoh GR II side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T1 IR has external dimensions of 129 x 90 x 47 mm (5.08 x 3.54 x 1.85″) and weighs 440 g (0.97 lb / 15.52 oz) (including batteries). Ricoh GR II has external dimensions of 111.7 x 61 x 34.7 mm (4.61 x 3.27 x 1.38″) and weighs 251 g (0.55 lb / 8.85 oz) (including batteries).
Below you can see the front view size comparison of Fujifilm X-T1 IR and Ricoh GR II. Ricoh GR II is clearly the smaller of the two cameras. Its body is 17mm narrower, 29mm shorter and 12mm thinner than Fujifilm X-T1 IR. As you can tell, actually this is not a fair size comparison since Ricoh GR II has a built-in lens but Fujifilm X-T1 IR doesn't. Once you put a lens on X-T1 IR, its thickness will increase significantly.
Here is the back view size comparison of Fujifilm X-T1 IR and Ricoh GR II.
Now lets look at the top view comparison of Fujifilm X-T1 IR and Ricoh GR II.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh GR II is significantly lighter (189g ) than the Fujifilm X-T1 IR 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 X-T1 IR, the total kit will weigh much higher.
With its weather sealed body, we believe that X-T1 IR has a big advantage over GR II which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Fujifilm X-T1 IR and Ricoh GR II's LCD screens has the same diagonal size of 3".
On the other hand, Fujifilm X-T1 IR 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 II has a fixed type screen which provides less flexibility in shooting positions compared to X-T1 IR.
