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 G12 and Ricoh GXR GR Lens A12 28mm side-by-side from the front, back and top in their relative dimensions. Canon G12 has external dimensions of 112 x 76 x 48 mm (4.41 x 2.99 x 1.89″) and weighs 401 g (0.88 lb / 14.14 oz) (including batteries). Ricoh GXR GR Lens A12 28mm has external dimensions of 113 x 70 x 56 mm (4.45 x 2.76 x 2.2″) and weighs 140 g (0.31 lb / 4.94 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G12 and the Ricoh GXR GR Lens A12 28mm. Canon G12 is 1mm narrower and 8mm thinner than Ricoh GXR GR Lens A12 28mm but it is also 6mm taller.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh GXR GR Lens A12 28mm is significantly lighter (261g ) than the Canon G12 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot G12 nor Ricoh GXR GR Lens A12 28mm F2.5 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
Ricoh GXR GR Lens A12 28mm's 3.00" LCD screen is slightly larger than Canon G12's 2.8 screen.
On the other hand, Canon G12 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, Ricoh GXR GR Lens A12 28mm has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
