The Sony a7S scores a solid 55/100. Announced on April 6th, 2014, this mirrorless camera was launched at a price of $2,499. With dimensions of 127 x 94 x 48mm and weighing 489g or 1.08lbs, it is a compact and lightweight option.

Considering the camera’s specifications, it still holds up decently in today’s market. However, newer models have surpassed the a7S in terms of features and performance. Despite this, the Sony a7S remains a reliable choice for those seeking a mirrorless camera from 2014.

Sony a7S Overview and Optics

The Sony a7S receives a 60/100 score for its optics. With 12.2 megapixels, a shooting speed of 5 fps, and a CMOS sensor, this camera offers decent performance. The Bionz X processor and a DXOMARK score of 87 for the sensor contribute to its overall image quality. Utilizing a full-frame sensor size and Sony FE lens mount, the a7S accommodates a variety of lenses. However, it lacks image stabilization, which may prove challenging in certain shooting situations. The camera’s 3:2 aspect ratio is standard and versatile.

Despite these specifications, the Sony a7S faces competition in the market. Many contemporary cameras offer higher megapixel counts, faster shooting speeds, and built-in image stabilization. Nonetheless, the a7S remains a viable option for photographers who prioritize low-light performance and compact design. The optics score and specifications provide a clear understanding of the camera’s capabilities and limitations.

The higher the number of megapixels, the more detail the cameras sensor can capture.

Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
4240 x 2832 px
Sensor Type
The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality.
Sensor Size
The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture.

Lens Mount
The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras.
Sony FE
Image Processor
The image processor in the camera converts the information collected on the sensor for digital storage on the memory card.
Bionz X
Aspect Ratio
The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Minimum Shutter Speed
The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.
30 s
Maximum Shutter Speed
The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries.
1/ 8000 s
Autofocus Points
Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings.
In-body Stabilization
In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake.
Viewfinder Type
The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens.

Sony a7S Video Performance

The Sony a7S receives a video score of 56/100. It offers Full HD video resolution with maximum dimensions of 1920 x 1080 and a maximum frame rate of 60fps. However, it lacks built-in time-lapse functionality.

In the current market, these video specifications may not meet the expectations of professional videographers. Many competitors now offer 4K resolution, higher frame rates, and additional video features. The absence of time-lapse functionality also limits the creative possibilities for users.

The Sony a7S has decent video capabilities, but they do not stand out in today’s competitive market. Users seeking cutting-edge video features may want to explore other options.

In the current market, the Sony a7S has a decent feature set, but it does lack some modern conveniences. The absence of a touchscreen and Bluetooth may be disappointing for some users, while the flip screen and WiFi connectivity are useful additions. The screen resolution is adequate, but higher resolutions are available in other cameras.

The Sony a7S remains a solid choice for those who prioritize video and low light capabilities. However, users seeking advanced features and connectivity options may want to explore other options.

Sony a7S Storage and Battery

The Sony a7S scores 21/100 in storage and battery. This camera has a single memory card slot, accepting SD, SDHC, and SDXC cards, as well as Memory Stick Duo, Pro Duo, and Pro-HG Duo cards. The battery life of the Sony a7S is 380 shots, using the NP-FW50 battery type. However, this camera lacks USB charging capabilities.

Comparing these specifications to other cameras in today’s market, the Sony a7S falls short in both storage and battery life. Most modern cameras offer multiple memory card slots and longer battery life, making them more convenient for extended shooting sessions. The absence of USB charging further limits the Sony a7S’s flexibility and practicality.

Despite the camera’s impressive optics, video, and features, the storage and battery specifications of the Sony a7S are underwhelming when compared to current market standards. This may impact the decision of potential buyers who value convenience and extended shooting capabilities.
