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 A7S and Canon 400D side-by-side from the front, back and top in their relative dimensions. Sony A7S has external dimensions of 127 x 94 x 48 mm (5 x 3.7 x 1.89″) and weighs 489 g (1.08 lb / 17.25 oz) (including batteries). Canon 400D has external dimensions of 127 x 94 x 65 mm (5 x 3.7 x 2.56″) and weighs 556 g (1.23 lb / 19.61 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Canon 400D. Sony A7S has the same height and width with Canon 400D. On the other hand, with a thickness of 48mm, it is 17mm thinner.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A7S is 67g lighter than the Canon 400D 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 A7S has a Full frame sensor and Canon 400D has a smaller APS-C sensor, Canon 400D's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7S lenses.

Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over 400D which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S's 3 LCD screen is slightly larger than Canon 400D's 2.5" screen.
In addition to the size advantage, Sony A7S LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Canon 400D has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
Sony A7S has a 12.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Canon 400D has a 10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the A7S and 400D sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Canon 400D Cameras
As seen above, Sony A7S has a 2.6x Larger sensor area than Canon 400D. 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.
DxOMark Sensor Scores
Both Sony A7S and Canon 400D sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, A7S has scored 87, 25 points higher than 400D.

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 400D has an advantage over Sony A7S There are 326 lenses for Canon 400D's Canon EF/EF-S mount, on the other hand there are only 122 lenses for Sony A7S's Sony E lens mount.
Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 30 lenses for Sony E mount and 112 lenses for Canon EF/EF-S mount with IS.
