Sony A6500 versus Olympus E-M10 III

The Sony Alpha A6500 and the Olympus OM-D E-M10 Mark III are two digital cameras that were officially introduced, respectively, in October 2016 and August 2017. Both the A6500 and the E-M10 III are mirrorless interchangeable lens cameras that are based on an APS-C (A6500) and a Four Thirds (E-M10 III) sensor. The Sony has a resolution of 24 megapixel, whereas the Olympus provides 15.9 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 A6500 vs Olympus E-M10 III

The side-by-side display below illustrates the physical size and weight of the Sony A6500 and the Olympus E-M10 III. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the A6500 – represents the basis for the calculations 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 E-M10 III is notably larger (27 percent) than the Sony A6500. However, the E-M10 III is markedly lighter (9 percent) than the A6500. It is worth mentioning in this context that the A6500 is splash and dust resistant, while the E-M10 III 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 find an overview of optics for the two cameras in the Sony E-Mount Lens Catalog (A6500) and the Micro Four Thirds Lens Catalog (E-M10 III). 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 A6500 gets 350 shots out of its NP-FW50 battery, while the E-M10 III can take 330 images on a single charge of its BLS-50 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 III was launched at a markedly lower price (by 54 percent) than the A6500, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Sony A6500 vs Olympus E-M10 III

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony A6500 features an APS-C sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III 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 A6500 has a native 3:2 aspect ratio, while the one in the E-M10 III offers a 4:3 aspect.

With 24MP, the A6500 offers a higher resolution than the E-M10 III (15.9MP), but the A6500 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-M10 III) due to its larger sensor. However, the E-M10 III is a somewhat more recent model (by 10 months) than the A6500, 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 E-M10 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison: Sony A6500 vs Olympus E-M10 III

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 III offers a slightly higher resolution than the one in the A6500 (2360k vs 2300k dots). The table below summarizes some of the other core capabilities of the Sony A6500 and Olympus E-M10 III in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The A6500 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the E-M10 III uses SDXC cards.

Both the A6500 and the E-M10 III are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The A6500 replaced the earlier Sony A6300, while the E-M10 III followed on from the Olympus E-M10 II.

Review summary: Sony A6500 vs Olympus E-M10 III

So how do things add up? Is the Sony A6500 better than the Olympus E-M10 III or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Sony Alpha A6500:

• More detail: Offers more megapixels (24 vs 15.9MP) with a 25% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: Larger pixels generate images with better, more accurate colors.
• More dynamic range: Capable of capturing a wider spectrum of light and dark details.
• Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Faster burst: Shoots at higher frequency (11 vs 8.6 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (120x67mm vs 122x84mm) and thus needs less room in the bag.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been on the market for longer (launched in October 2016).

Advantages of the Olympus OM-D E-M10 Mark III:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
• More modern: Was introduced somewhat (10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the A6500 is the clear winner of the match-up (12 : 4 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A6500 or the E-M10 III handle or perform in practice. 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 table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
