Sony A7S vs Olympus E-30 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 Olympus E-30, which was introduced in March 2009 is a Advanced DSLR camera with a 12.0MP Four Thirds sensor. As you can see, E-30 is 5 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 Olympus E-30 before getting into our more detailed comparison.

Sony A7S vs Olympus E-30: 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 Olympus E-30 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). Olympus E-30 has external dimensions of 142 x 108 x 75 mm (5.59 x 4.25 x 2.95″) and weighs 695 g (1.53 lb / 24.52 oz) (including batteries).

Below you can see the front view size comparison of Sony A7S and Olympus E-30. Sony A7S is clearly the smaller of the two cameras. Its body is 15mm narrower, 14mm shorter and 27mm thinner than Olympus E-30.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Sony A7S is significantly lighter (206g ) than the Olympus E-30 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 Sony A7S has a Full frame sensor and Olympus E-30 has a smaller Four Thirds sensor, Olympus E-30'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 E-30 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7S's 3 LCD screen is slightly larger than Olympus E-30's 2.7" screen.

Sony A7S vs Olympus E-30: Sensor Comparison

Both Sony A7S and Olympus E-30 have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Olympus E-30's sensor is Four Thirds (17.3 x 13 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 Olympus E-30.

Below you can see the A7S and E-30 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Olympus E-30 Cameras

As seen above, Sony A7S has a 3.8x Larger sensor area than Olympus E-30. 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 Olympus E-30 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, 32 points higher than E-30.

Model	Overall	Color Depth	Dynamic Range	Low-light ISO
Sony A7S	87	23.9 bits	13.2 Evs	3702 ISO
Olympus E-30	55	21.3 bits	10.4 Evs	530 ISO

Sony A7S vs Olympus E-30 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 A7S has an advantage over Olympus E-30. There are 128 lenses for Sony A7S's Sony E mount, on the other hand there are only 45 lenses for Olympus E-30's Four Thirds lens mount.

Another important factor is the availability of image stabilization. Olympus E-30 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. On the other hand, Sony A7S doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 31 lenses for Sony E mount with Optical Image Stabilization features.
