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-A2 and Fujifilm X-A1 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A2 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries). Fujifilm X-A1 has external dimensions of 117 x 67 x 39 mm (4.6 x 2.62 x 1.54″) and weighs 330 g (0.73 lb / 11.64 oz) (including batteries).
Below you can see the front view size comparison of Fujifilm X-A2 and Fujifilm X-A1. Fujifilm X-A2 has the same height and width with Fujifilm X-A1. On the other hand, with a thickness of 40mm, it is 1mm thicker.
Here is the back view size comparison of Fujifilm X-A2 and Fujifilm X-A1.
Now lets look at the top view comparison of Fujifilm X-A2 and Fujifilm X-A1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A1 is 20g lighter than the Fujifilm X-A2 but we don't think this will make a significant difference.
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 Fujifilm X-A2 and Fujifilm X-A1 have the same Fujifilm X lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Unfortunately neither Fujifilm X-A2 nor Fujifilm X-A1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Mirrorless Cameras with Weather Sealing
