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
Thanks to the weather-sealed body of the RS1500, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SX1 IS.
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.
