Ricoh G900 vs Panasonic G2: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Ricoh G900 and Panasonic G2 side-by-side from the front, back and top in their relative dimensions. Ricoh G900 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries). Panasonic G2 has external dimensions of 124 x 84 x 74 mm (4.88 x 3.31 x 2.91″) and weighs 428 g (0.94 lb / 15.10 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Panasonic G2. Ricoh G900 is clearly the smaller of the two cameras. Its body is 6mm narrower, 18mm shorter and 41mm thinner than Panasonic G2. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic G2 doesn't. Once you put a lens on G2, its thickness will increase significantly.

Now lets look at the top view comparison of Ricoh G900 and Panasonic G2.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Ricoh G900 is significantly lighter (181g ) than the Panasonic G2 which may become a big advantage especially on long walking trips.

Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G2, the total kit will weigh much higher.

Weather Sealing

Thanks to the weather sealed body of G900, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to G2.

LCD Screen Size and Features

Ricoh G900 and Panasonic G2's LCD screens has the same diagonal size of 3.00".

On the other hand, Panasonic G2 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. Ricoh G900's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G2.
Ricoh G900 vs Panasonic G2: Sensor Comparison

Ricoh G900 has a 20.0MP 1/2.3 (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Panasonic G2 has a 12.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine HD II processor.

Ricoh G900's sensor provides 8MP more than Panasonic G2's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Below you can see the G900 and G2 sensor size comparison.

As seen above, Panasonic G2 has a 8.0x Larger sensor area than Ricoh G900. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
