Sony A7R versus Sony A6300

The Sony Alpha A7R and the Sony Alpha A6300 are two enthusiast cameras that were officially introduced, respectively, in October 2013 and February 2016. Both the A7R and the A6300 are mirrorless interchangeable lens cameras that are based on a full frame (A7R) and an APS-C (A6300) sensor. The A7R has a resolution of 36.2 megapixel, whereas the A6300 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 A7R vs Sony A6300

The physical size and weight of the Sony A7R and the Sony A6300 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions 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 – the A7R – 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 Sony A6300 is considerably smaller (33 percent) than the Sony A7R. Moreover, the A6300 is markedly lighter (13 percent) than the A7R. 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 (A7R) and the Sony E-Mount Lens Catalog (A6300). 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 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 A6300 was launched at a markedly lower price (by 57 percent) than the A7R, 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 A7R vs Sony A6300

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 Sony A7R features a full frame sensor and the Sony A6300 an APS-C sensor. The sensor area in the A6300 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.

Sensor size

With 36.2MP, the A7R offers a higher resolution than the A6300 (24MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.91μm for the A6300) due to its larger sensor. However, the A6300 is a somewhat more recent model (by 2 years and 3 months) than the A7R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the A7R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

A7R versus A6300 MP
Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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 review, the A7R has a notably higher overall DXO score than the A6300 (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 0.4 EV in additional dynamic range, and 0.9 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A6300 provides a better video resolution than the A7R. It can shoot movie footage at 4K/30p, while the A7R is limited to 1080/60p.

Feature comparison: Sony A7R vs Sony A6300

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 A7R offers a slightly higher resolution than the one in the A6300 (2400k vs 2300k dots). The table below summarizes some of the other core capabilities of the Sony A7R and Sony A6300 in connection with corresponding information for a sample of similar cameras.

Both the A7R and the A6300 have been discontinued, but can regularly be found used on eBay. The A7R was replaced by the Sony A7R II, while the A6300 was followed by the Sony A6500.

Review summary: Sony A7R vs Sony A6300

So how do things add up? Is the Sony A7R better than the Sony A6300 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Sony Alpha A7R:

  • More detail: Offers more megapixels (36.2 vs 24MP) with a 23% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 922k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More heavily discounted: Has been available for much longer (launched in October 2013).

Arguments in favor of the Sony Alpha A6300:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (11 vs 4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 127x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 61g or 13 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (400 versus 340) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
  • More modern: Reflects 2 years and 3 months of technical progress since the A7R launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A6300 comes out slightly ahead of the A7R (9 : 8 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.

A7R 08:09 A6300

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7R or the A6300. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
