Sony A6000 versus Olympus PEN-F

The Sony Alpha A6000 and the Olympus PEN-F are two enthusiast cameras that were revealed to the public, respectively, in February 2014 and January 2016. Both the A6000 and the PEN-F are mirrorless interchangeable lens cameras that are based on an APS-C (A6000) and a Four Thirds (PEN-F) sensor. The Sony has a resolution of 24 megapixel, whereas the Olympus provides 20.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony A6000 vs Olympus PEN-F

The side-by-side display below illustrates the physical size and weight of the Sony A6000 and the Olympus PEN-F. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the A6000 – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus PEN-F is notably larger (12 percent) than the Sony A6000. Moreover, the PEN-F is markedly heavier (24 percent) than the A6000. In this context, it is worth noting that neither the A6000 nor the PEN-F are weather-sealed.

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 find an overview of optics for the two cameras in the Sony E-Mount Lens Catalog (A6000) and the Micro Four Thirds Lens Catalog (PEN-F). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the A6000 gets 360 shots out of its NP-FW50 battery, while the PEN-F can take 330 images on a single charge of its BLN-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 A6000 was launched at a markedly lower price (by 50 percent) than the PEN-F, 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: Sony A6000 vs Olympus PEN-F

The size of the imaging sensor is a crucial determinant 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 Sony A6000 features an APS-C sensor and the Olympus PEN-F a Four Thirds sensor. The sensor area in the PEN-F is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the A6000 has a native 3:2 aspect ratio, while the one in the PEN-F offers a 4:3 aspect.

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

Sony A6000 and Olympus PEN-F sensor measures

With 24MP, the A6000 offers a higher resolution than the PEN-F (20.2MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the PEN-F) due to its larger sensor. However, the PEN-F is a somewhat more recent model (by 1 year and 11 months) than the A6000, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the PEN-F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the A6000, the PEN-F has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

A6000 versus PEN-F MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the A6000 has a notably higher overall DXO score than the PEN-F (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.7 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Sony A6000 vs Olympus PEN-F

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the PEN-F offers a substantially higher resolution than the one in the A6000 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Sony A6000 and Olympus PEN-F in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The A6000 has one, while the PEN-F does not. While the build-in flash of the A6000 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the PEN-F features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The A6000 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the PEN-F uses SDXC cards.

The PEN-F is a current model that online retailers, such as amazon, will have in stock. In contrast, the A6000 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A6000 was succeeded by the Sony A6300.

Review summary: Sony A6000 vs Olympus PEN-F

So what conclusions can be drawn? Is the Sony A6000 better than the Olympus PEN-F or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Sony Alpha A6000:

  • More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
  • More compact: Is smaller (120x67mm vs 125x72mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 83g or 19 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2014).

ilogo

Advantages of the Olympus PEN-F:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A6000 comes out slightly ahead of the PEN-F (11 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

A6000 11:10 PEN-F

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the A6000 and the PEN-F in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
