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 Fujifilm X-T1 and Ricoh PX side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T1 has external dimensions of 129 x 90 x 47 mm (5.08 x 3.54 x 1.84″) and weighs 440 g (0.97 lb / 15.52 oz) (including batteries). Ricoh PX has external dimensions of 100 x 55 x 21 mm (3.94 x 2.17 x 0.83″) and weighs 156 g (0.34 lb / 5.50 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T1 and the Ricoh PX. Ricoh PX is clearly the smaller of the two cameras. Its body is 29mm narrower, 35mm shorter and 26mm thinner than Fujifilm X-T1. As you can tell, actually this is not a fair size comparison since Ricoh PX has a built-in lens but Fujifilm X-T1 doesn't. Once you put a lens on X-T1, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm X-T1 and Ricoh PX.
Now lets look at the top view comparison of Fujifilm X-T1 and Ricoh PX.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh PX is significantly lighter (284g ) than the Fujifilm X-T1 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, the total kit will weigh much higher.
Weather Sealing
Both the X-T1 and the PX have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Fujifilm X-T1's 3.00" LCD screen is slightly larger than Ricoh PX's 2.7" screen.
In addition to the size advantage, Fujifilm X-T1 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Ricoh PX has a fixed type screen which provides less flexibility in shooting positions compared to X-T1.
