Ricoh G900 vs Sigma Quattro H: 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 Sigma Quattro H 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). Sigma Quattro H has external dimensions of 147 x 95 x 91 mm (5.79 x 3.74 x 3.58″) and weighs (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Sigma Quattro H. Ricoh G900 is clearly the smaller of the two cameras. Its body is 29mm narrower, 29mm shorter and 58mm thinner than Sigma Quattro H. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Sigma Quattro H doesn't. Once you put a lens on Quattro H, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Sigma Quattro H is 247g lighter than the Ricoh G900 but we don't think this will make a significant difference.

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 Quattro H, the total kit will weigh much higher.

LCD Screen Size and Features

Ricoh G900 and Sigma Quattro H's LCD screens has the same diagonal size of 3".

Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Ricoh G900 vs Sigma Quattro H: Sensor Comparison

Ricoh G900 has a 20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Sigma Quattro H has a 45.0MP APS-H (26.6 x 17.9 mm ) sized CMOS (Foveon X3) sensor and features Dual TRUE III processor.

Sigma Quattro H's sensor provides 25MP more than Ricoh G900'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 Quattro H sensor size comparison.
