Panasonic G9 vs Pentax K-01: 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 Panasonic G9 and Pentax K-01 side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Pentax K-01 has external dimensions of 122 x 79 x 58 mm (4.8 x 3.11 x 2.28″) and weighs 561 g (1.24 lb / 19.79 oz) (including batteries).

Below you can see the front view size comparison of Panasonic G9 and Pentax K-01. Pentax K-01 is clearly the smaller of the two cameras. Its body is 15mm narrower, 18mm shorter and 34mm thinner than Panasonic G9.

Now lets look at the top view comparison of Panasonic G9 and Pentax K-01.

Top View Comparison image of Panasonic G9 and Pentax K-01 Size

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Pentax K-01 is significantly lighter (97g ) than the Panasonic G9 which may become a big advantage especially on long walking trips.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Pentax K-01 has an APS-C sized sensor and Panasonic G9 has a smaller Four Thirds sensor, Panasonic G9's lenses for a similar focal length and aperture will generally be lighter and smaller than the Pentax K-01 lenses.

Weather Sealing

With its weather sealed body, we believe that G9 has a big advantage over K-01 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Panasonic G9 and Pentax K-01's LCD screens has the same diagonal size of 3".

On the other hand, Panasonic G9 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. Pentax K-01's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G9.

Panasonic G9 vs Pentax K-01: Sensor Comparison

Panasonic G9 has a 20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Pentax K-01 has a 16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor .

Another difference between these two cameras is that Panasonic G9's sensor lacks 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 G9 and K-01 sensor size comparison.

Sensor Size and Resolution Comparison image of Panasonic G9 and Pentax K-01 Cameras

As seen above, Pentax K-01 has a 1.7x Larger sensor area than Panasonic G9. 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.

Panasonic G9 vs Pentax K-01 Comparison of Available Lenses

Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Pentax K-01 has an advantage over Panasonic G9 There are 156 lenses for Pentax K-01's Pentax KAF2 mount, on the other hand there are only 108 lenses for Panasonic G9's Micro Four Thirds lens mount.

Another important factor is the availability of image stabilization. Both Panasonic G9 and Pentax K-01 has Sensor based Image stabilization which means that all the lenses will be stabilized in these bodies. G9's built-in Image stabilization system is effective to compensate vibration up to 6.5-stops according to CIPA standards.
