Sony A7S vs Canon 450D Comparison Overview

Here we are comparing two cameras with different body types: Sony A7S, which was introduced in April 2014 is a Pro Mirrorless camera with a 12.0MP Full frame sensor whereas Canon 450D, which was introduced in May 2008 is a Entry-Level DSLR camera with a 12.0MP APS-C sensor. As you can see, 450D is 6 years older than A7S. Let's see if this age difference between two cameras makes a big difference.

Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting.

Here is a brief look at the main features of Sony A7S and Canon 450D before getting into our more detailed comparison.

Sony A7S vs Canon 450D: 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 A7S and Canon 450D 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 450D has external dimensions of 129 x 98 x 62 mm (5.08 x 3.86 x 2.44″) and weighs 524 g (1.16 lb / 18.48 oz) (including batteries).

Below you can see the front view size comparison of Sony A7S and Canon 450D. Sony A7S is clearly the smaller of the two cameras. Its body is 2mm narrower, 4mm shorter and 14mm thinner than Canon 450D.

Here is the back view size comparison of Sony A7S and Canon 450D.

Now lets look at the top view comparison of Sony A7S and Canon 450D.

Top View Comparison image of Sony A7S and Canon 450D Size

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Sony A7S is 35g lighter than the Canon 450D 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 450D has a smaller APS-C sensor, Canon 450D'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 450D which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7S and Canon 450D's LCD screens has the same diagonal size of 3.

On the other hand, Sony A7S 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 Canon 450D has a fixed type screen which provides less flexibility in shooting positions compared to A7S.

Sony A7S vs Canon 450D: Sensor Comparison

Both Sony A7S and Canon 450D have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Canon 450D's sensor is APS-C (22.2 x 14.8 mm ).

Since Sony A7S's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon 450D.

Below you can see the A7S and 450D sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Canon 450D Cameras

As seen above, Sony A7S has a 2.6x Larger sensor area than Canon 450D. 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 450D 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, 26 points higher than 450D.

Model	Overall	Color Depth	Dynamic Range	Low-light ISO
Sony A7S	87	23.9 bits	13.2 Evs	3702 ISO
Canon 450D	61	21.9 bits	10.8 Evs	692 ISO

Sony A7S vs Canon 450D 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 450D has an advantage over Sony A7S There are 326 lenses for Canon 450D's Canon EF/EF-S mount, on the other hand there are only 128 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 31 lenses for Sony E mount and 112 lenses for Canon EF/EF-S mount with IS.
