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 Pentax RS1500 and Canon SX1 IS side-by-side from the front, back and top in their relative dimensions. Pentax RS1500 has external dimensions of 114 x 58 x 28 mm (4.49 x 2.28 x 1.1″) and weighs 157 g (0.35 lb / 5.54 oz) (including batteries). Canon SX1 IS has external dimensions of 128 x 88 x 88 mm (5.04 x 3.46 x 3.46″) and weighs 615 g (1.36 lb / 21.69 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax RS1500 and the Canon SX1 IS. Pentax RS1500 is clearly the smaller of the two cameras. Its body is 14mm narrower, 30mm shorter and 60mm thinner than Canon SX1 IS.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax RS1500 is significantly lighter (458g ) than the Canon SX1 IS which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the RS1500 has a big advantage over the SX1 IS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon SX1 IS's 2.80" LCD screen is slightly larger than Pentax RS1500's 2.7" screen.
Moreover, Canon SX1 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, Pentax RS1500 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX1 IS.
