Sony A7R III vs Sigma Quattro H: 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 Sony A7R III and Sigma Quattro H side-by-side from the front, back and top in their relative dimensions. Sony A7R III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 657 g (1.45 lb / 23.17 oz) (including batteries). Sigma Quattro H has external dimensions of 147 x 95 x 91 mm (5.79 x 3.74 x 3.58″) and weighs 635g (including batteries).

Below you can see the front view size comparison of Sony A7R III and Sigma Quattro H. Sony A7R III is 20mm narrower and 17mm thinner than Sigma Quattro H but it is also 1mm taller.

Now lets look at the top view comparison of Sony A7R III and Sigma Quattro H.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Sigma Quattro H is 657g lighter than the Sony A7R III 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 Sony A7R III has a Full frame sensor and Sigma Quattro H has a smaller APS-H sensor, Sigma Quattro H's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7R III lenses.

LCD Screen Size and Features

Sony A7R III and Sigma Quattro H's LCD screens has the same diagonal size of 3.00".

On the other hand, Sony A7R III features a Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Sigma Quattro H has a fixed type screen which provides less flexibility in shooting positions compared to A7R III.
Sony A7R III vs Sigma Quattro H: Sensor Comparison

Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Sigma Quattro H has a 45.0MP APS-H (26.6 x 17.9 mm ) sized CMOS (Foveon X3) sensor and features Dual TRUE III processor.

Another difference between these two cameras is that Sony A7R III'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 A7R III and Quattro H sensor size comparison.

As seen above, Sony A7R III has a 1.8x Larger sensor area than Sigma Quattro H. 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.

Sony A7R III vs Sigma Quattro H 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 Sony A7R III has an advantage over Sigma Quattro H. There are 184 lenses for Sony A7R III's Sony E mount, on the other hand there are only 77 lenses for Sigma Quattro H's Sigma SA Bayonet lens mount.

Another important factor is the availability of image stabilization. Sony A7R III has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. A7R III's built-in Image stabilization system is effective to compensate vibration up to 5.0-stops according to CIPA standards.
On the other hand, Sigma Quattro H doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 29 lenses for Sigma SA Bayonet mount with Optical Image Stabilization features.
