Sony a7s II

The Sony a7S II Mirrorless Digital Camera, which is making significant progress in the video arena, provides an excellent combination of sensitivity, dynamic range, resolution, and speed to assist a varied multimedia workflow.

The a7S II is based on a full-frame 12.2MP Exmor CMOS sensor and is capable of internal UHD 4K recording at 30 frames per second with complete pixel readout as well as 1080p recording at up to 120 frames per second in the XAVC S codec, among other things.

The BIONZ X image processor, which works in conjunction with the sensor for both stills and video recording, allows for increased sensitivity to ISO 409600, continuous shooting at up to 5 frames per second, and quick intelligent focusing with low-light sensitivity of -4 EV.

The 5-axis SteadyShot INSIDE image stabilization system adjusts for vertical, horizontal, pitch, yaw, and roll camera motions, allowing for crisper, smoother handheld recording even in low-light situations, further enhancing working efficiency.

A redeveloped recording setup, which includes the ability to use S-Log3 Gamma and S-Gamut3 in addition to S-Log2, complements the 4K recording capabilities. This allows for increased dynamic range values of up to 1300 percent, which is more compatible with high-end post-production workflows than the previous S-Log2 setup.

A Gamma Display Assist feature, which converts S-Log2 and S-Log3 settings to the ITU709 gamma for easier on-camera viewing, helps to preview imagery with natural contrast by converting S-Log2 and S-Log3 settings to the ITU709 gamma for easier on-camera viewing. For clearer monitoring potential, an improved Zebra function better supports working with S-Log gamma settings.

The a7S II is also distinguished by its tiny, yet durable, magnesium alloy body design, which contains a high-magnification 0.78x Tru-Finder OLED electronic viewfinder with a 0.78x magnification. A resolution of 2.36 million dots and a Zeiss T* anti-reflective coating make it ideal for working in a range of lighting conditions.

It also allows you to evaluate exposure and setting modifications before recording. A 3.0 in the rear “A 1,228,800-dot LCD screen is also available, and it has a tilting design that allows it to be used from both high and low angles while working. The camera’s built-in Wi-Fi and NFC capabilities also enable you to associate mobile devices with the camera for wireless sharing and remotely controlling the camera’s functions.

BIONZ X image processor and Exmor sensor with full frame capture

Full-frame Exmor CMOS sensor with 12.2MP resolution and a BIONZ X image processor work together to provide a wide dynamic range with little noise and exceptional sensitivity from ISO 100-102400, with the ability to be expanded to ISO 50-409600. When combined with the huge individual pixel size provided by the 12.2MP sensor, this camera is well-suited for usage in low-light circumstances.

A new-generation RGB color filter array, as well as a gapless on-chip lens design, are also included in the sensor’s architecture. Together, these two technologies provide extremely efficient light-gathering capabilities, which further enhance the low noise and high sensitivity of the device’s architecture. An anti-reflective coating was also put to the seal glass of the image sensor, which helps to reduce surface reflections, glare, and ghosting, resulting in images that are contrast-rich and color-neutral.

Additionally, the sensor and CPU combination provides a slew of performance-related advantages for still photography, including a continuous shooting rate of 5 frames per second in Speed Priority mode and 2.5 frames per second in Continuous Autofocus mode.

For low-light performance and accuracy in low-light circumstances down to -4 EV, the Fast Intelligent AF system uses 169 AF points, which are divided into 25 contrast-detection points and nine central AF points that have been divided into 16 segments each.

Internal UHD 4K recording and full pixel readout are also available on this model.

A wide range of frame rates up to 30 frames per second may be recorded internally in UHD 4K, and because to the 12.2MP resolution, complete pixel readout is available, which means that there is no need for pixel binning, resulting in higher quality images with decreased moiré and aliasing.

It is also possible to record in full HD 1080p at frame rates of up to 120 frames per second, and both resolutions make use of the 100 Mbps XAVC S codec, which is stored behind an MP4 wrapper with 4:2:0 sampling. The high-speed, 120-frame-per-second recording also allows for 4x and 5x slow-motion video recording at frame rates of either 30p or 24p, depending on the frame rate setting.

An optional external recorder capable of clear 4K recording with 4:2:2 sampling can be used in conjunction with the high-resolution internal recordings made possible by the uncompressed HDMI output, which is also available.

5-Axis SteadyShot Image Stabilization INSIDE the camera

The compact a7S II is equipped with a 5-axis SteadyShot INSIDE image stabilization technology that provides 4.5 stops of effective stabilization for five different forms of camera wobble that can occur while shooting stills and video with the camera in handheld mode. The ability to utilize any lens, even adapted lenses, for important images without encountering blur due to camera shake is a huge advantage for photographers.

When working with lengthy focal lengths, the system will compensate for pitch and yaw corrections automatically. The incorporation of horizontal and vertical shift correction will, on the other hand, be beneficial for macro and high-magnification pictures.

The roll compensation will be beneficial to photographers of all shooting types. No matter if you are using third-party lenses and adapters or lenses with built-in optical stabilization, all five axes of stabilization will always be active and working properly.

Custom color profiles and S-Log3 gamma are both available.

Support is now available for the S-Gamut3.Cine/S-Log-3 and S-Gamut3/S-Log3 profiles, which provide up to a 1300 percent wider dynamic range for smoother tonal and color gradations, as well as improved sensitivity and clarity in shadows and mid-tones.

The S-Gamut3.Cine/S-Log-3 profile provides up to a 1300 percent wider dynamic range for smoother tonal and color gradations, as well The use of these profiles allows for more interoperability within a professional workflow, and they are particularly well-suited to the Cineon Log gamma curve, which allows for versatile post-production grading and color management.

Aside from that, the S-Log3 gamma setting provides an impressive 14-stop wide dynamic range, allowing for greater control over highlights and shadows. The S-Gamut3.Cine profile, on the other hand, can be used to simulate the qualities of scanned negative film while providing a wide gamut comparable to the DCI-P3 color space.

S-Log3 gamma settings are also available in addition to the more common S-Log2 gamma settings.

Assist with Zebra and Gamma Displays

An improved Zebra function is particularly well suited for use with S-Log gamma profiles, and it may be used to keep track of exposure levels in situations with strong contrast. Video signal level goals may be set anywhere between 0 and 109, and particular ranges can be defined to facilitate adjusting the exposure level easy.

However, when using S-Log settings, a Gamma Display Assist option is also available, which displays scenes with natural contrast when the camera is set to this mode. This function transforms pictures to the ITU709 profile, which allows for simpler on-camera monitoring of the captured images.

Timecode and User Bit Settings are two important considerations.

The a7S II offers a variety of timecode recording options to accommodate a variety of workflows. It has the standard “Record Run” mode, which only advances the timecode when recording, as well as the “Free Run” mode, which allows you to record without stopping “It is possible to use a timecode that advances the timecode even when not recording, which is useful for synchronizing multiple cameras during live events.

Timecode can be recorded in both drop frame and non-drop frame modes, and it can also be recorded in drop frame mode. When recording internally, the a7S II has the ability to broadcast timecode over the HDMI port as well.

The viewfinder, which has a 4-lens optical system with double-sided aspherical elements, accurately depicts what will appear in your video, including the impacts of your camera settings. You’ll like the rich tone gradations and enhanced contrast. Composition at eye level is pleasant and solid thanks to features such as 100 percent frame coverage and a 0.78x magnification provided by high-end components.

In addition to the electronic viewfinder, a back 3.0 inch LCD screen is included “In addition, a 1,228.8k-dot LCD monitor has been built into the design, which can be tilted 107° upward or 41° downward to allow for easier functioning from high and low angles, respectively.

Built-in Wi-Fi connectivity, as well as NFC functionality

A7S II has built-in Wi-Fi connectivity, which allows it to rapidly transfer photographs to mobile devices for uploading and sharing online to social networking sites, sending emails, or uploading images to cloud storage services.

Near Field Communication (NFC) is also enabled, allowing for one-touch connection between the camera and compatible mobile devices without the need for any complicated set-up. If a mobile device is connected to the camera, it may also display a live view image on its screen and control the camera’s shutter remotely.

Additional PlayMemories Camera Apps are enabled through the camera’s built-in Wi-Fi connection, allowing you to customize the camera’s functions based on your preferred shooting style. A wide range of apps are available to assist with the creation of portraits, detailed close-ups, sports, time-lapse photography, motion photography, and other sorts of photos.
