Sony Alpha ILCE-7 III (ILCE7M3) Body

The mirrorless digital camera Sony ILCE-7 III is characterized by its updated sensor design and is a camera that is suitable for both photo and video applications with a variety of work situations

The newly developed 24.2 MP Exmor R BSI CMOS sensor and BIONZ X image processor are optimized for improved speed and low-light performance, enabling an impressive continuous shooting rate of 10 frames per second and improved autofocus performance for faster and more reliable subject tracking.

The updated Fast Hybrid AF system uses a combination of 693 phase detection points and 425 contrast detection areas for very fast focus acquisition in almost all lighting conditions and maintains focus on the subject more effectively. In addition to speed and autofocus, the processing improvements also ensure clearer images with greatly reduced noise throughout the sensitivity range of ISO 100-51200, which can even be extended to ISO 50-204800.

Video recording capabilities have been enhanced for improved quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing. Additionally, the a7 III utilizes 5-axis SteadyShot INSIDE sensor-shift image stabilization, which minimizes the occurrence of camera shake by up to 5 stops.

Aside from the imaging system updates, the body design of the Sony a7 III has also been revised to include a rear 3.0" 922k-dot touchscreen LCD, which features a tilting design to better support high and low angle work. A Tru-Finder OLED EVF viewfinder with 2.36 million pixels is responsible for bright and clear subject recognition,

two SD memory card slots are now available for greater shooting flexibility, and a larger NP-FZ100 battery can now also be used to provide up to approximately 710 shots per charge. The body is made of a robust magnesium alloy for use in tough conditions, and this and the a7 III's weather sealing also make the body resistant to dust and moisture.

24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor
The 24.2-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to deliver high-resolution still images and video while minimizing noise and improving speed. This sensor design works with an on-chip lens design and anti-reflective coating, as well as the elimination of the optical low-pass filter, to improve shooting quality and increase detail.

In addition, a copper wire layer improves data transfer speed for the creation of 14-bit high resolution stills with a native sensitivity of ISO 100-51200, which can be extended to ISO 50-204800. In addition, the internal UHD enables 4K video recording with a wide dynamic range utilizing the full width of the full-frame sensor.

The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times while capturing an impressive 15 stops of dynamic range at low sensitivity levels. The sensor and processor combination also enables fast continuous shooting at up to 10 frames per second at full resolution, for up to 177 consecutive frames and with full-time AF/AE, whether using the mechanical shutter or the electronic shutter. When shooting in Live View mode, a continuous shooting rate of up to 8 frames per second is still possible.

Fast Hybrid AF system
An advanced 4D FOCUS system now uses a combination of 693 phase detection points, covering approximately 93% of the frame, together with 425 contrast detection areas to ensure reliable and fast autofocus and subject tracking. This fast hybrid AF system now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as significantly improved focusing in low light.

The use of phase detection points now enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens adapters with full continuous AF/AE tracking compatibility.

The Sony a7 III offers extensive customizable color and gamma controls, allowing users to adjust gamma, black level, knee, color level and more. Users can also utilize the same S-Log2 gamma curve found on high-end Sony Cinema, which brings up to 1300% more dynamic range to the video signal than the conventional REC709, increasing flexibility in post-production.

HLG (Hybrid Log-Gamma) support is also available for recording within a wide color space in addition to the BT.2020 color space. In addition to S-Log2, S-Log3 is also available to create an effective 14-stop dynamic range with improved grading control in the shadow to mid-tone range of the image.

Body design and integrated Wi-Fi/Bluetooth
The XGA OLED Tru-Finder EVF with a resolution of 2.36 million pixels and 0.78x magnification is responsible for a bright, clear and detailed image. This viewfinder design also enables the use of autofocus in focus magnifier mode as well as improved focusing to support manual focusing. In addition to the EVF, a 3.0" 922k-dot LCD is also mounted on the back of the camera, featuring a touch panel design for intuitive operation and focusing. The screen can also be tilted 107° upwards and 41° downwards to make it easier to work at high and low angles, while

the magnesium alloy chassis guarantees rigidity, durability and stability while keeping the weight down. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved to allow for more comfortable one-handed holding.

Weather sealing is used to resist dust and moisture and ensure reliable operation in harsh weather conditions.

With the NP-FZ100 battery, the a7 III has improved battery life and is now rated for approximately 710 shots per charge. Dual SD memory card slots allow flexible file storage and editing and can be configured to partition raw and JPEG files or be used for overflow recording. One of the card slots is designed to support UHS-II memory cards. In addition to a micro USB port, a USB 3.0 Type-C port has been added to enable faster and more reliable tethering support. The USB Type-C port allows the camera to be charged via the host power source while plugged in, and

built-in Wi-Fi enables the Sony a7 III to instantly share images to mobile devices for direct online sharing to social networks, email and cloud. NFC (Near Field Communication) is also supported, enabling a one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the connected mobile device can also display a live image on its screen and remotely control the camera shutter. Bluetooth connectivity allows location data to be captured.

Other camera features
The "Ratings" feature allows you to assign values from 1-5 stars to images in the camera for faster editing and sorting during post-processing at home.

An advanced 1200-zone evaluative metering sensor delivers consistent and accurate results with multi-segment metering, center-weighted metering or spot metering. Highlight and Average metering modes help prevent blow-out highlights and ensure stable automatic exposure, while

Sigma 50mm f1.4 DG DN (A) Sony E-mount

The "Art F1.4" standard with uncompromising optical performance

Based on the latest optical design technology, the lens contains 14 elements in 11 groups, including 3 aspherical lenses and 1 SLD glass element. This optical design effectively eliminates various aberrations, such as astigmatism and field curvature, which cannot be corrected by the camera.

Despite the large aperture of F1.4, the imaging performance has not been neglected at the edges of the image and sagittal coma has been minimized to such an extent that this lens can also withstand astrophotography and low-light photography with demanding subjects and point light sources at a wide-open aperture. In addition to a clear image without color blur over the entire image circle, the natural, soft bokeh comes into its own at F1.4.

High-speed AF for fast and convenient shooting

The SIGMA 50mm F1.4 DG DN Art is the first model in the Art product line

to

be

developed

exclusively for mirrorless

full-frame cameras and uses the "HLA" (High-response Linear Actuator) linear motor. In addition, by using a single double-sided aspherical lens as the focusing element, the lens offers fast and quiet focusing and high tracking performance despite its large aperture. With a maximum aperture of F1.4 and a powerful AF system, the lens can be used in a variety of situations, including shooting in low light, moving subjects, snapshots and video.

Powerful, yet slim and compact

When developing the SIGMA 50mm F1.4 DG DN Art, the focus was also on slimming down the lens barrel by reducing the weight of a focus lens and optimizing the layout of the lens unit. The aim was to achieve the "optimal size" for mirrorless systems without compromising the concept of "maximum optical performance" of SIGMA's Art line. With this lens, it has been possible to achieve both first-class performance and the size required for lightweight and mobile photographic tools.

Extensive functions and high build quality

The lens is extensively equipped. It offers a focus mode switch, an aperture ring click switch for switching the click on and off when selecting the aperture via the aperture ring and an aperture ring lock switch that prevents unintentional adjustment of the aperture ring. It also has an AFL button, which can be assigned any camera function depending on the camera model.

All functions can be operated intuitively. The SIGMA 50mm F1.4 DG DN Art is dust and splash-proof and the front element of the lens has a water and oil-repellent coating, making it suitable for challenging shooting environments. The lens is compact, lightweight and easy to use, while offering the high build quality guaranteed by the reliable "Made in Japan" processing technology of the Aizu factory.
