Ricoh G900 vs Sony A390: 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 Sony A390 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). Sony A390 has external dimensions of 128 x 97 x 86 mm (5.04 x 3.82 x 3.39″) and weighs 549 g (1.21 lb / 19.37 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Sony A390. Ricoh G900 is clearly the smaller of the two cameras. Its body is 10mm narrower, 31mm shorter and 53mm thinner than Sony A390. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Sony A390 doesn't. Once you put a lens on A390, 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. Ricoh G900 is significantly lighter (302g ) than the Sony A390 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 A390, the total kit will weigh much higher.

LCD Screen Size and Features

Ricoh G900's 3" LCD screen is slightly larger than Sony A390's 2.7" screen.

On the other hand, Sony A390 LCD screen 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, Ricoh G900 has a fixed type screen which provides less flexibility in shooting positions compared to A390.

Ricoh G900's sensor provides 6MP more than Sony A390'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.
