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 Canon SX30 IS and Nikon 1 V1 side-by-side from the front, back and top in their relative dimensions. Canon SX30 IS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 601 g (1.32 lb / 21.20 oz) (including batteries). Nikon 1 V1 has external dimensions of 113 x 76 x 44 mm (4.45 x 2.99 x 1.71″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX30 IS and the Nikon 1 V1. Nikon 1 V1 is clearly the smaller of the two cameras. Its body is 10mm narrower, 16mm shorter and 64mm thinner than Canon SX30 IS. As you can tell, actually this is not a fair size comparison since Canon SX30 IS has a built-in lens but Nikon 1 V1 doesn't. Once you put a lens on 1 V1, its thickness will increase significantly.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon 1 V1 is significantly lighter (218g ) than the Canon SX30 IS 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 V1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX30 IS nor Nikon 1 V1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon 1 V1's 3.00" LCD screen is slightly larger than Canon SX30 IS's 2.7" screen.
On the other hand, Canon SX30 IS sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Nikon 1 V1 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX30 IS.
