Sony A6000 versus Nikon D7100

The Sony Alpha A6000 and the Nikon D7100 are two enthusiast cameras that were officially introduced, respectively, in February 2014 and February 2013. The A6000 is a mirrorless interchangeable lens camera, while the D7100 is a DSLR. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel. 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 A6000 vs Nikon D7100

The physical size and weight of the Sony A6000 and the Nikon D7100 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 – the A6000 – 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 Nikon D7100 is considerably larger (81 percent) than the Sony A6000. Moreover, the D7100 is substantially heavier (122 percent) than the A6000. It is noteworthy in this context that the D7100 is splash and dust-proof, while the A6000 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. 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 (A6000) and the Nikon Lens Catalog (D7100). Mirrorless cameras, such as the Sony A6000, 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.

Concerning battery life, the A6000 gets 360 shots out of its NP-FW50 battery, while the D7100 can take 950 images on a single charge of its EN-EL15 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 A6000 was launched at a markedly lower price (by 50 percent) than the D7100, 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 A6000 vs Nikon D7100

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixel. This similarity in sensor specs implies that both the A6000 and the D7100 have the same pixel density, as well as the same pixel size. It should, however, be noted that the A6000 is a somewhat more recent model (by 11 months) than the D7100, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 (1080/60p).

Feature comparison: Sony A6000 vs Nikon D7100

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A6000 has an electronic viewfinder (1440k dots), while the D7100 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 adjacent table lists some of the other core features of the Sony A6000 and Nikon D7100 along with similar information for a selection of comparators.

Both the A6000 and the D7100 have been discontinued, but can regularly be found used on eBay. The D7100 was replaced by the Nikon D7200, while the A6000 was followed by the Sony A6300.

Review summary: Sony A6000 vs Nikon D7100

So what is the bottom line? Which of the two cameras – the Sony A6000 or the Nikon D7100 – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Advantages of the Sony Alpha A6000:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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.
  • Faster burst: Shoots at higher frequency (11 vs 6 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 136x107mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 421g or 55 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 category (50 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 11 months after the D7100).

logo checkmark

Arguments in favor of the Nikon D7100:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (950 versus 360) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been on the market for longer (launched in February 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 comes out slightly ahead of the A6000 (10 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

A6000 09:10 D7100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A6000 or the D7100. 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 full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated 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.
