Sony A6100 vs A7C
The Sony Alpha A6100 and the Sony Alpha A7C are two digital cameras that were officially introduced, respectively, in August 2019 and September 2020. Both the A6100 and the A7C are mirrorless interchangeable lens cameras that are based on an APS-C (A6100) and a full frame (A7C) sensor. Both cameras offer a resolution of 24 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A6100 and the Sony Alpha A7C? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Sony A6100 and the Sony A7C. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The A6100 can be obtained in three different colors (black, silver, white), while the A7C is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7C is notably larger (10 percent) than the Sony A6100. Moreover, the A7C is markedly heavier (29 percent) than the A6100. It is noteworthy in this context that the A7C is splash and dust-proof, while the A6100 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Sony E-Mount Lens Catalog (A6100) and the Sony FE Lens Catalog (A7C). 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.
Concerning battery life, the A6100 gets 420 shots out of its NP-FW50 battery, while the A7C can take 740 images on a single charge of its NP-FZ100 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A6100 was launched at a markedly lower price (by 58 percent) than the A7C, 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 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 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony A6100 features an APS-C sensor and the Sony A7C a full frame sensor. The sensor area in the A7C is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the A7C has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the A7C has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.91μm for the A6100), which gives it a potential advantage in terms of light gathering capacity. In addition, the A7C is a somewhat more recent model (by 1 year) than the A6100, and its sensor might have benefitted from technological advances during this time.
The Sony Alpha A6100 has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Sony Alpha A7C are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, 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 review are similar with respect to both having an electronic viewfinder. However, the one in the A7C offers a substantially higher resolution than the one in the A6100 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Sony A6100 and Sony A7C in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The A6100 has one, while the A7C does not. While the built-in flash of the A6100 is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sony A6100 and the Sony A7C both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the A6100 and the A7C write their files to SDXC or Memory Stick PRO Duo cards. The A7C supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A6100 can use UHS-I cards (up to 104 MB/s).
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Alpha A6100 and Sony Alpha A7C and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7C has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The A6100 lacks such a headphone port.
Both the A6100 and the A7C are recent models that are part of the current product line-up. The A6100 replaced the earlier Sony A6000, while the A7C does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So how do things add up? Is there a clear favorite between the Sony A6100 and the Sony A7C? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Sony Alpha A6100:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.59x).
- Less heavy: Is lighter (by 113g or 22 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (58 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2019).
Advantages of the Sony Alpha A7C:
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Longer lasting: Gets more shots (740 versus 420) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Was introduced somewhat (1 year) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the A7C is the clear winner of the contest (13 : 5 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 A6100 or the A7C 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
