Ricoh G900 vs Panasonic GH5S Comparison Overview

Here we are comparing two cameras with different body types: Ricoh G900, which was introduced in February 2018 is a Waterproof camera with a 20.0MP 1/2.3 sensor whereas Panasonic GH5S, which was introduced in January 2018 is a Pro Mirrorless camera with a 10.0MP Four Thirds sensor. There is only 1 months difference between G900 and GH5S so we are expecting this to be a fair comparison regarding age and technology level.

Ricoh G900 vs Panasonic GH5S: 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 GH5S 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 GH5S has external dimensions of 139 x 98 x 87 mm (5.47 x 3.86 x 3.43″) and weighs 660 g (1.46 lb / 23.28 oz) (including batteries).

Below you can see the front view size comparison of Ricoh G900 and Panasonic GH5S. Ricoh G900 is clearly the smaller of the two cameras. Its body is 21mm narrower, 32mm shorter and 54mm thinner than Panasonic GH5S. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic GH5S doesn't. Once you put a lens on GH5S, its thickness will increase significantly.

Here is the back view size comparison of Ricoh G900 and Panasonic GH5S.

Now lets look at the top view comparison of Ricoh G900 and Panasonic GH5S.

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 (413g ) than the Panasonic GH5S 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 GH5S, the total kit will weigh much higher.

LCD Screen Size and Features

Panasonic GH5S's 3.20" LCD screen is slightly larger than Ricoh G900's 3 screen.

Moreover, Panasonic GH5S 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 G900 has a fixed type screen which provides almost no flexibility in shooting positions compared to GH5S.
Ricoh G900 vs Panasonic GH5S: 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 GH5S has a 10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine 10 processor.

Ricoh G900's sensor provides 10MP more than Panasonic GH5S'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.

One other difference between these two cameras that is worth mentioning is that Panasonic GH5S's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Below you can see the G900 and GH5S sensor size comparison.

As seen above, Panasonic GH5S 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.
