Ricoh G900 vs Pentax K-r: 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 Pentax K-r 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). Pentax K-r has external dimensions of 125 x 97 x 68 mm (4.92 x 3.82 x 2.68″) and weighs 598 g (1.32 lb / 21.09 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Pentax K-r. Ricoh G900 is clearly the smaller of the two cameras. Its body is 7mm narrower, 31mm shorter and 35mm thinner than Pentax K-r. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Pentax K-r doesn't. Once you put a lens on K-r, its thickness will increase significantly.

Now lets look at the top view comparison of Ricoh G900 and Pentax K-r.

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 (351g ) than the Pentax K-r 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 K-r, 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 K-r.

LCD Screen Size and Features

Ricoh G900 and Pentax K-r's LCD screens has the same diagonal size of 3.00".

Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Ricoh G900 vs Pentax K-r: 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, Pentax K-r has a 12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features Prime II processor.

Ricoh G900's sensor provides 8MP more than Pentax K-r'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 K-r sensor size comparison.
