Olympus E-400 vs Sony A7S II

The Olympus E-400 and the Sony Alpha 7S II are two digital cameras that were revealed to the public, respectively, in September 2006 and September 2015. The E-400 is a DSLR, while the A7S II is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-400) and a full frame (A7S II) sensor. The Olympus has a resolution of 10 megapixels, whereas the Sony provides 12 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-400 and the Sony Alpha 7S II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Olympus E-400 and the Sony A7S II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Compare E-400 versus A7S II top
Comparison E-400 or A7S II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is somewhat larger (3 percent) than the Olympus E-400. Moreover, the A7S II is substantially heavier (44 percent) than the E-400. It is noteworthy in this context that the A7S II is splash and dust-proof, while the E-400 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-400) and the Sony FE Lens Catalog (A7S II). Mirrorless cameras, such as the A7S II, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the E-400 gets 500 shots out of its BLS-1 battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The power pack in the A7S II can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-400 was launched at a markedly lower price (by 77 percent) than the A7S II, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

 

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-400 features a Four Thirds sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-400 has a native 4:3 aspect ratio, while the one in the A7S II offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-400 and Sony A7S II sensor measures

With 12MP, the A7S II offers a higher resolution than the E-400 (10MP), but the A7S II nevertheless has larger individual pixels (pixel pitch of 8.40μm versus 4.74μm for the E-400) due to its larger sensor. Moreover, the A7S II is a much more recent model (by 8 years and 11 months) than the E-400, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A7S II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7S II for good quality output (200 dots per inch) amounts to 21.2 x 14.2 inch or 53.8 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inch or 43.1 x 28.8 cm, and for excellent quality (300 dpi) 14.1 x 9.4 inch or 35.9 x 24 cm. The corresponding values for the Olympus E-400 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-400 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

Many modern cameras are not only capable of taking still images, but can also record movies. The A7S II indeed provides for movie recording, while the E-400 does not. The highest resolution format that the A7S II can use is 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k dots), while the E-400 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the A7S II offers a wider field of view (100%) than the one in the E-400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7S II has a higher magnification (0.78x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Olympus E-400, the Sony A7S II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-400 has one, while the A7S II does not. While the built-in flash of the E-400 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The E-400 writes its imaging data to Compact Flash or xD Picture cards, while the A7S II uses SDXC or Memory Stick PRO Duo cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7S II only has one slot.

 

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus E-400 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-400 does not offer wifi capability.

The A7S II is a recent model that features in the current product line-up of Sony. In contrast, the E-400 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-400 was succeeded by the Olympus E-410. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.

Review summary

So what is the bottom line? Is the Olympus E-400 better than the Sony A7S II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (21 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-400 07:21 A7S II

How about other alternatives? Do the specifications of the Olympus E-400 and the Sony A7S II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-400 or the A7S II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
