Olympus E-1 vs Sony A7S II

The Olympus E-1 and the Sony Alpha 7S II are two professional cameras that were announced, respectively, in June 2003 and September 2015. The E-1 is a DSLR, while the A7S II is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-1) and a full frame (A7S II) sensor. The Olympus has a resolution of 4.9 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.

Body comparison

The physical size and weight of the Olympus E-1 and the Sony A7S II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

Size Olympus E-1 vs Sony A7S II
Compare E-1 versus A7S II top
Comparison E-1 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 notably smaller (17 percent) than the Olympus E-1. Moreover, the A7S II is markedly lighter (15 percent) than the E-1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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-1) 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-1 gets 750 shots out of its Olympus BLM-1 battery, while the A7S II can take 370 images on a single charge of its Sony 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.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-1 was launched at a markedly lower price (by 43 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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-1 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-1 has a native 4:3 aspect ratio, while the one in the A7S II offers a 3:2 aspect.

Olympus E-1 and Sony A7S II sensor measures

With 12MP, the A7S II offers a higher resolution than the E-1 (4.9MP), but the A7S II nevertheless has larger individual pixels (pixel pitch of 8.40μm versus 6.78μm for the E-1) due to its larger sensor. Moreover, the A7S II is a much more recent model (by 12 years and 2 months) than the E-1, 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 inches or 53.8 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inches or 43.1 x 28.8 cm, and for excellent quality (300 dpi) 14.1 x 9.4 inches or 35.9 x 24 cm. The corresponding values for the Olympus E-1 are 12.8 x 9.6 inches or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inches or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inches or 21.7 x 16.3 cm for excellent quality prints.

The Olympus E-1 has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-3200. 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.

In terms of underlying technology, the E-1 is build around a CCD sensor, while the A7S II uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

E-1 versus A7S II MP

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S II has an electronic viewfinder (2400k dots), while the E-1 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A7S II has a higher magnification than the one of the E-1 (0.78x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-1 and Sony A7S II in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the E-1, but is missing on the A7S II is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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-1 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-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7S II only has one slot.

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-1 does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-1 (unlike the A7S II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-1 and the A7S II have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the A7S II was followed by the Sony A7S III. Further information on the features and operation of the E-1 and A7S II can be found, respectively, in the Olympus E-1 Manual (free pdf) or the online Sony A7S II Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (22 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-1 07:22 A7S II

How about other alternatives? Do the specifications of the Olympus E-1 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-1 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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
