Canon 6D MII vs Sony A99 II: 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 Canon 6D MII and Sony A99 II side-by-side from the front, back and top in their relative dimensions. Canon 6D MII has external dimensions of 144 x 111 x 75 mm (5.67 x 4.37 x 2.95″) and weighs 765 g (1.69 lb / 26.98 oz) (including batteries). Sony A99 II has external dimensions of 143 x 104 x 76 mm (5.63 x 4.09 x 2.99″) and weighs 849 g (1.87 lb / 29.95 oz) (including batteries).

Below you can see the front view size comparison of Canon 6D MII and Sony A99 II. Sony A99 II is 1mm narrower and 7mm shorter than Canon 6D MII but it is also 1mm thicker.

Now lets look at the top view comparison of Canon 6D MII and Sony A99 II.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon 6D MII is 84g lighter than the Sony A99 II but we don't think this will make a significant difference.

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 both Canon 6D MII and Sony A99 II have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

LCD Screen Size and Features

Canon 6D MII and Sony A99 II's LCD screens has the same diagonal size of 3".

Canon 6D MII vs Sony A99 II: Sensor Comparison

Canon 6D MII has a 26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Sony A99 II has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor.

Sony A99 II's sensor provides 16MP more than Canon 6D MII'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 Sony A99 II'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 6D MII and A99 II sensor size comparison.

Sensor Size and Resolution Comparison image of Canon 6D MII and Sony A99 II Cameras

Canon 6D MII and Sony A99 II have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 6D MII has 62% larger pixel area compared to Sony A99 II, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.

DxOMark Sensor Scores

DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 6D MII and Sony A99 II sensors have been tested by DxO and the results show that A99 II has a better overall score of 92, 7 points higher compared to 6D MII's score of 85.

Model	Overall	Color Depth	Dynamic Range	Low-light ISO
Canon 6D MII	85	24.4 bits	11.9 Evs	2862 ISO
Sony A99 II	92	25.4 bits	13.4 Evs	2317 ISO

Canon 6D MII vs Sony A99 II 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 Canon 6D MII has an advantage over Sony A99 II. There are 250 lenses for Canon 6D MII's Canon EF mount, on the other hand there are only 143 lenses for Sony A99 II's Sony/Minolta Alpha lens mount.

Another important factor is the availability of image stabilization. Sony A99 II has a big advantage in this regard because it has a sensor based image stabilization which means that all the lenses mounted to this body will be stabilized. A99 II's built-in Image stabilization system is effective to compensate vibration up to 4.5-stops according to CIPA standards.
On the other hand, Canon 6D MII doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 76 lenses for Canon EF mount with Optical Image Stabilization features.
