Olympus E-P1 vs Sony A6500
The Olympus PEN E-P1 and the Sony Alpha A6500 are two enthusiast cameras that were officially introduced, respectively, in June 2009 and October 2016. Both the E-P1 and the A6500 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-P1) and an APS-C (A6500) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Sony provides 24 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 PEN E-P1 and the Sony Alpha A6500? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-P1 and the Sony A6500. 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 dimensions are rounded to the nearest millimeter.
The E-P1 can be obtained in three different colors (black, silver, white), while the A6500 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6500 is notably smaller (5 percent) than the Olympus E-P1. However, the A6500 is markedly heavier (28 percent) than the E-P1. It is noteworthy in this context that the A6500 is splash and dust-proof, while the E-P1 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 Micro Four Thirds Lens Catalog (E-P1) and the Sony E-Mount Lens Catalog (A6500). 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 E-P1 gets 300 shots out of its BLS-1 battery, while the A6500 can take 350 images on a single charge of its NP-FW50 power pack. The power pack in the A6500 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.

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-P1 was launched at a markedly lower price (by 43 percent) than the A6500, 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-P1 features a Four Thirds sensor and the Sony A6500 an APS-C sensor. The sensor area in the A6500 is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-P1 has a native 4:3 aspect ratio, while the one in the A6500 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 24MP, the A6500 offers a higher resolution than the E-P1 (12.2MP), but the A6500 has smaller individual pixels (pixel pitch of 3.91μm versus 4.29μm for the E-P1). Yet, the A6500 is a much more recent model (by 7 years and 3 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A6500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6500 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The A6500 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha A6500 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
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 consideration, the A6500 offers substantially better image quality than the E-P1 (overall score 30 points higher). The advantage is based on 3.1 bits higher color depth, 3.3 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A6500 provides a better video resolution than the E-P1. It can shoot movie footage at 4K/30p, while the Olympus is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A6500 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-P1 and Sony A6500 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A6500 has a touchscreen, while the E-P1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 A6500 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-P1 writes its imaging data to SDHC cards, while the A6500 uses SDXC or Memory Stick PRO Duo cards. The A6500 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 cannot take advantage of Ultra High Speed SD cards.
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 PEN E-P1 and Sony Alpha A6500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
| NFC |
It is notable that the A6500 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P1 does not provide wifi capability.
Both the E-P1 and the A6500 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the A6500 was followed by the Sony A6600. 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.
So what conclusions can be drawn? Is the Olympus E-P1 better than the Sony A6500 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Olympus PEN E-P1:
- Less heavy: Is lighter (by 98g or 22 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).

If the count of relative strengths (bullet points above) is taken as a measure, the A6500 is the clear winner of the contest (22 : 3 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. 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.
How about other alternatives? Do the specifications of the Olympus E-P1 and the Sony A6500 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-P1 and the A6500 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 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], 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.

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 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.
