Sony A6300 versus Canon 70D

The Sony Alpha A6300 and the Canon EOS 70D are two enthusiast cameras that were announced, respectively, in February 2016 and July 2013. The A6300 is a mirrorless interchangeable lens camera, while the 70D is a DSLR. Both cameras are equipped with an APS-C sensor. The Sony has a resolution of 24 megapixel, whereas the Canon provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Sony A6300 and the Canon 70D is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 A6300 – 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 Canon 70D is considerably larger (80 percent) than the Sony A6300. Moreover, the 70D is substantially heavier (87 percent) than the A6300. 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Sony E-Mount Lens Catalog (A6300) and the Canon EF Lens Catalog (70D). Mirrorless cameras, such as the Sony A6300, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems 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 A6300 was launched at a somewhat lower price (by 17 percent) than the 70D, which makes it more attractive for photographers on a tight budget. 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

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

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 70D is 8 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (A6300) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the A6300 offers a higher resolution than the 70D (20MP), but the A6300 has smaller individual pixels (pixel pitch of 3.91μm versus 4.11μm for the 70D). However, the A6300 is a somewhat more recent model (by 2 years and 7 months) than the 70D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Sensor resolution

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 A6300 provides substantially higher image quality than the 70D, with an overall score that is 17 points higher. This advantage is based on 1.9 bits higher color depth, 2.1 EV in additional dynamic range, and 0.6 stops in additional 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A6300 provides a higher video resolution than the 70D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A6300 has an electronic viewfinder (2300k dots), while the 70D 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 A6300 and Canon 70D in connection with corresponding information for a sample of similar cameras.

Both the A6300 and the 70D have been discontinued, but can regularly be found used on ebay. The 70D was replaced by the Canon 80D, while the A6300 was followed by the Sony A6500.

Summary

So how do things add up? Is the Sony A6300 better than the Canon 70D or vice versa? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of the Sony Alpha A6300:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.1 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Faster burst: Shoots at higher frequency (11 vs 7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 139x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 351g or 46 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
  • More modern: Reflects 2 years and 7 months of technical progress since the 70D launch.

Reasons to prefer the Canon EOS 70D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (920 versus 400) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in July 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the A6300 is the clear winner of the match-up (13 : 8 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.

A6300 13:08 70D

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 A6300 or the 70D. 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
