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 Panasonic FZ300 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). Panasonic FZ300 has external dimensions of 132 x 92 x 117 mm (5.2 x 3.62 x 4.61″) and weighs 691 g (including batteries).
Below you can see the front view size comparison of Fujifilm X-T1 IR and Panasonic FZ300. Fujifilm X-T1 IR is clearly the smaller of the two cameras. Its body is 3mm narrower, 2mm shorter and 70mm thinner than Panasonic FZ300. As you can tell, actually this is not a fair size comparison since Panasonic FZ300 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 Panasonic FZ300.
Now lets look at the top view comparison of Fujifilm X-T1 IR and Panasonic FZ300.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-T1 IR is significantly lighter (251g ) than the Panasonic FZ300 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.
