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 Panasonic ZS1 and Nikon 1 AW1 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS1 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Nikon 1 AW1 has external dimensions of 114 x 72 x 37 mm (4.47 x 2.81 x 1.46″) and weighs 356 g (0.78 lb / 12.6 oz) (including batteries).
Below you can see the front view size comparison of Panasonic ZS1 and Nikon 1 AW1. Panasonic ZS1 is clearly the smaller of the two cameras. Its body is 11mm narrower, 12mm shorter and 4mm thinner than Nikon 1 AW1. As you can tell, actually this is not a fair size comparison since Panasonic ZS1 has a built-in lens but Nikon 1 AW1 doesn't. Once you put a lens on 1 AW1, its thickness will increase significantly.
Here is the back view size comparison of Panasonic ZS1 and Nikon 1 AW1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS1 is significantly lighter (127g ) than the Nikon 1 AW1 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 1 AW1, the total kit will weigh much higher.
LCD Screen Size and Features
Nikon 1 AW1's 3" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
