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 G15 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 G15 has external dimensions of 107 x 76 x 40 mm (4.21 x 2.99 x 1.57″) and weighs 352 g (0.78 lb / 12.42 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax RS1500 and the Canon G15. Pentax RS1500 is 18mm shorter and 12mm thinner than Canon G15 but it is also 7mm wider.
Here is the back view size comparison of the Pentax RS1500 and Canon G15.
Now lets look at the top view comparison of Pentax RS1500 and Canon G15.
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 (195g ) than the Canon G15 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 G15 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G15's 3.00" LCD screen is slightly larger than Pentax RS1500's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
