Sony A900 versus Sony A6500

The Sony Alpha A900 and the Sony Alpha A6500 are two digital cameras that were revealed to the public, respectively, in September 2008 and October 2016. The A900 is a DSLR, while the A6500 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (A900) and an APS-C (A6500) sensor. The A900 has a resolution of 24.4 megapixel, whereas the A6500 provides 24 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 A900 vs Sony A6500

The side-by-side display below illustrates the physical size and weight of the Sony A900 and the Sony A6500. Three successive views from the front, the top, and the rear are shown. All size dimensions 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 side – the A900 – 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 Sony A6500 is considerably smaller (56 percent) than the Sony A900. Moreover, the A6500 is substantially lighter (49 percent) than the A900. 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the A900 gets 880 shots out of its NP-FM500H battery, while the A6500 can take 350 images on a single charge of its NP-FW50 power pack.

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 camera comparisons there.

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 A6500 was launched at a markedly lower price (by 53 percent) than the A900, 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 A900 vs Sony A6500

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A900 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.

Sony A900 and Sony A6500 sensor measures

With 24.4MP, the A900 offers a slightly higher resolution than the A6500 (24MP), but the A900 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.91μm for the A6500) due to its larger sensor. However, the A6500 is a somewhat more recent model (by 8 years) than the A900, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

A900 versus A6500 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the A6500 has a markedly higher DXO score than the A900 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, 0 stops of reduced low light sensitivity. 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. The A6500 indeed provides for movie recording, while the A900 does not. The highest resolution format that the A6500 can use is 4K/30p.

 

Feature comparison: Sony A900 vs Sony A6500

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A6500 has an electronic viewfinder (2300k dots), while the A900 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 table below summarizes some of the other core capabilities of the Sony A900 and Sony A6500 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The A6500 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A900 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A900 was succeeded by the Sony A99.

Review summary: Sony A900 vs Sony A6500

So what is the bottom line? Is there a clear favorite between the Sony A900 and the Sony A6500? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Sony Alpha A900:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Can take more shots (880 versus 350) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in September 2008).


Advantages of the Sony Alpha A6500:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 156x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 442g or 49 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
  • More modern: Reflects 8 years of technical progress since the A900 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A6500 is the clear winner of the contest (13 : 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 before making a decision on a new camera.

A900 05:13 A6500

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A900 or the A6500 handle or perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. 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 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
