Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax W90 is significantly lighter (227g ) than the Pentax MX-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Thanks to the weather-sealed body of the W90, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the MX-1.
LCD Screen Size and Features
Pentax MX-1's 3.00" LCD screen is slightly larger than Pentax W90's 2.7" screen.
In addition to the size advantage, Pentax MX-1 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Pentax W90 has a fixed type screen which provides less flexibility in shooting positions compared to MX-1.
