Sony A9 versus Sony A6500
The Sony Alpha A9 and the Sony Alpha A6500 are two digital cameras that were announced, respectively, in April 2017 and October 2016. Both the A9 and the A6500 are mirrorless interchangeable lens cameras that are based on a full frame (A9) and an APS-C sensor. Both cameras offer a resolution of 24 megapixel.
The physical size and weight of the Sony A9 and the Sony A6500 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 A9 – represents 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 Sony A6500 is notably smaller (34 percent) than the Sony A9. Moreover, the A6500 is markedly lighter (33 percent) than the A9. 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 find an overview of optics for the two cameras in the Sony FE Lens Catalog (A9) 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A6500 was launched at a markedly lower price (by 69 percent) than the A9, 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 size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony A9 features a full frame sensor and the Sony A6500 an APS-C sensor. The sensor area in the A6500 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the A9 has a larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the A9 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.91μm for the A6500), which gives it a potential advantage in terms of light gathering capacity. In addition, the A9 is a somewhat more recent model (by 6 months) than the A6500, and its sensor might have benefitted from technological advances during this time.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 A9 has a notably higher overall DXO score than the A6500 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.4 EV of lower dynamic range, and 1.3 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the A9 offers a substantially higher resolution than the one in the A6500 (3686k vs 2300k dots). The adjacent table lists some of the other core features of the Sony A9 and Sony A6500 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the A9 and the A6500 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 A9 does not have a direct predecessor.
So what is the bottom line? Is there a clear favorite between the Sony A9 and the Sony A9? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Sony Alpha A9:
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (1.3 stops ISO advantage).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (3686k vs 2300k dots).
- More detailed LCD: Has a higher resolution rear screen (1440k vs 922k dots).
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (20 vs 11 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (650 versus 350) on a single battery charge.
- More modern: Is somewhat more recent (announced 6 months after the A6500).
Arguments in favor of the Sony Alpha A6500:
- More compact: Is smaller (120x67mm vs 127x96mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 220g or 33 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in April 2017).
If the count of relative strengths (bullet points above) is taken as a measure, the A9 emerges as the winner of the contest (8 : 5 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A9 or the A6500 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. An an alternative, you can also directly jump to any one of the listed comparisons that were previously generated by the CAM-parator tool.
