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 Panasonic FZ40 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). Panasonic FZ40 has external dimensions of 120 x 80 x 92 mm (4.72 x 3.15 x 3.62″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T1 and the Panasonic FZ40. Panasonic FZ40 is 9mm narrower and 10mm shorter than Fujifilm X-T1 but it is also 45mm thicker. As you can tell, actually this is not a fair size comparison since Panasonic FZ40 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 Panasonic FZ40.
Now lets look at the top view comparison of Fujifilm X-T1 and Panasonic FZ40.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T1 is 54g lighter than the Panasonic FZ40 but we don't think this will make a significant difference.
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
With its weather-sealed body, we believe that the X-T1 has a big advantage over the FZ40 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Fujifilm X-T1 and Panasonic FZ40's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-T1 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 Panasonic FZ40 has a fixed type screen which provides less flexibility in shooting positions compared to X-T1.
