The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony A7C was launched in the US market at a price of $1,799. 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 with a 35mm slide
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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
The Sony A7C features a full frame sensor and has a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the Sony A7C among the large-sensor cameras that aim for top notch image quality.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 alternative cameras.

Many modern cameras cannot only take still pictures, but also record videos. The A7C indeed provides movie recording capabilities. The highest resolution format that the A7C can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7C has an electronic viewfinder with a resolution of 2360k dots. The viewfinder offers a field of view of 100% and a magnification of 0.59x. The tables below summarize some of the other core capabilities of the Sony A7C in connection with corresponding information for a sample of similar cameras.

The LCD screen on the Sony Alpha A7C is flexibly attached to the body. In particular, the LCD is hinged on the side and can be flipped out for odd-angle shots in both portrait and landscape orientation. Also, this fully articulated, swivel type of LCD attachment is often appreciated by videographers for its flexibility. Moreover, v-loggers like the design because the screen can be turned to be front-facing.
One feature that differentiates the A7C from many older cameras is in-body image stabilization (IBIS). The A7C reduces the risk of handshake-induced blur with all attached lenses, while cameras without IBIS have to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
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 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 microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
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 A7C. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. 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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
Sony A7C FAQ
Below are some additional questions and answers concerning some particular features of the A7C.
What technology is the imaging sensor in the A7C based on?
The camera is build around a BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Sony equipped the A7C with the BIONZ X image processor.
What is the ISO sensitivity range of the A7C?
The camera has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the A7C is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the Sony Alpha A7C?
Sony mentions a shutter rating of 200 000 actuations for the A7C. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the A7C over, say, three years, one would have to take about 200 pictures each and every day.
Is completely silent shooting possible with the Sony A7C?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Sony Alpha A7C has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Sony A7C?
The A7C offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Sony A7C feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The A7C's flash sync speed is 1/160 sec.
Does the Sony A7C support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards (data transfer speed of up to 312 MB/s).
Which battery does the A7C use?
Where can I find the best deals for the A7C?
