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 Nikon L840 and Sony a5000 side-by-side from the front, back and top in their relative dimensions. Nikon L840 has external dimensions of 114 x 89 x 96 mm (4.49 x 3.5 x 3.78″) and weighs 538 g (1.19 lb / 18.98 oz) (including batteries). Sony a5000 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L840 and the Sony a5000. Sony a5000 is clearly the smaller of the two cameras. Its body is 4mm narrower, 26mm shorter and 60mm thinner than Nikon L840. As you can tell, actually this is not a fair size comparison since Nikon L840 has a built-in lens but Sony a5000 doesn't. Once you put a lens on a5000, its thickness will increase significantly.
Here is the back view size comparison of the Nikon L840 and Sony a5000.
Now lets look at the top view comparison of Nikon L840 and Sony a5000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony a5000 is significantly lighter (269g ) than the Nikon L840 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 a5000, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Nikon Coolpix L840 nor Sony Alpha a5000 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
