When using the new microphones from Sony with XLR adapter, the Multi Interface Shoe with digital audio interface delivers recordings in high sound quality.

A new dimension in image quality

The Alpha 7R IVA is equipped with a newly developed back-illuminated 35 mm full-frame CMOS image sensor with a resolution of 61 MP - the first of its kind in the world. The new sensor's back-illuminated design and effective noise reduction ensure ultra-low noise and high sensitivity for maximum image quality. In addition, the camera offers an impressive 15 stops of dynamic range at low sensitivity for seamless, natural gradations from dark shadows to bright highlights. Algorithms adopted from the latest Alpha cameras also ensure outstanding colour reproduction.

This new full-frame model incorporates an innovative 5-axis image stabilization system that has been optimized for the high-resolution shooting capabilities of this camera, allowing a shutter speed advantage of 5.5 stops to be achieved. The shutter has also been adapted to reduce even small movements that could otherwise cause camera shake.

The Alpha 7R IVA's viewfinder also features the highest resolution of any camera from Sony: a 5.76 million pixel UXGA OLED Tru-Finder electronic viewfinder. This is around 1.6 times the resolution of the electronic viewfinder of the Alpha 7R III, meaning that this new viewfinder reproduces every motif ultra-accurately and true to life. A standard or high display quality and a refresh rate of 60 or 120 frames per second can be set for optimum adaptation to the subject and shooting conditions.

In addition, the Pixel Shift Multi Shooting mode has been further developed for the new camera, which composes up to 16 images in full resolution. In this mode, the camera precisely shifts the sensor in 1 or 0.5 pixel increments to create 16 individual images with different pixel counts and a total of 963.2 million pixels. These are then combined in the [Imaging Edge] desktop application to create an image with 240.8 million pixels (19,008 x 12,672 pixels). This optimized mode is ideal for architectural photography, fine art photography and all other static subjects and produces images with highly impressive detail and color accuracy.

Shooting and focusing speed

The innovative new Alpha 7R IVA full-frame mirrorless camera can capture full-frame 61 MP (JPEG/RAW) images at up to 10 frames per second with consistently accurate AF/AE tracking for approximately 7 seconds, or 26.2 MP in APS-C sized mode at approximately 3 times that speed. These high-speed options also capture fast-moving subjects ultra-accurately and with impressive detail.

The Alpha 7R IVA's advanced focusing system includes 567 AF phase detection points, covering around 74% of the image area, and 425 AF contrast points for added accuracy and reliability in low light and other shooting situations where contrast AF is ideal. The new camera's higher AF sensor density and revised tracking algorithms significantly improve tracking performance, so that even complex or sudden subject movements are now tracked more reliably and accurately than ever before.

The Alpha 7R IVA also supports Real-Time AF with Eye Detection, which uses artificial intelligence to detect and process eye position in real time, providing ultra-precise focus on the subject's eye throughout. This function is available for people and animals. Depending on the shooting situation, you can choose between AF with animal or human eye detection. A real-time tracking function is also available, which uses a newly developed subject recognition algorithm to ensure even more precise subject tracking and permanent focusing system tracking. The anti-flicker recording mode automatically detects neon light and artificial lighting and minimizes the corresponding effects on the final image.

Optimized networking for professional workflows

The new Alpha 7R IVA full-frame camera from Sony is equipped with a range of advanced networking features for professional workflows. The new model offers WLAN with support for the standard 2.4 GHz band as well as the 5 GHz high-speed band for faster and more stable data transfer. A wireless remote PC networking function (wireless tethering shooting) is also available with the Alpha 7R IVA - a first for Sony cameras. This feature, requested by many professionals, opens up new freedoms for studio and on-location shooting - photographers can now move freely.

In addition to high-speed WiFi and wireless PC networking, the full-frame camera is also equipped with a SuperSpeed USB (USB 3.2 Gen 1) USB Type-C port, which supports ultra-fast data transfer and, in combination with Imaging Edge software, almost doubles the data transfer rate compared to the Alpha 7R III. The camera also features FTP data transfer, which sends images to a specified remote FTP server while images are still being captured or reviewed.

To support efficient, networked high-speed workflows for professionals, Sony announced version 2.0 of the Imaging Edge desktop applications (Remote/Viewer/Edit). Remote allows users to control cameras and monitor live footage from the PC screen. Viewer" allows users to quickly preview, rate and select photos from large libraries. Edit" can be used to create high-quality images from RAW data, while

the latest version of the Imaging Edge Mobile application from Sony can now transfer images to a connected smartphone even when disconnected from the power supply.

4K and professional movie functions with high resolution

In addition to its impressive photo shooting capabilities, the Alpha 7R IVA is also an excellent movie camera with 4K video recording (3840 x 2160 pixels) and full pixel display without pixel binning in Super 35mm mode, delivering 4K content with high detail and outstanding depth. S-Log 2 and S-Log 3 also ensure highly flexible color design and S-Log 3 offers a dynamic range of up to 14 levels. HLG (Hybrid Log-Gamma) is also available with the Alpha 7R IVA to support direct HDR workflows.

For autofocus when shooting video, this versatile new full-frame camera uses an optimized fast hybrid autofocus system that speeds up autofocus when filming, making it more seamless and stable - even when an object temporarily moves in front of the subject. The

Alpha 7R IVA is the first camera from Sony with real-time AF with eye detection for movie shooting

.

When this function is activated, the subject's eye is automatically tracked with ultra-precision and ultra-reliability, allowing the filmmaker to concentrate on the subject instead of having to worry about focusing. The Touch Tracking function also automatically starts AF with eye detection when a person is selected as the subject.

Another notable feature for video recording is the new digital audio interface on the camera's Multi Interface Shoe (MI Shoe), which allows direct connection of the optional ECM-B1M Shotgun Microphone for high-quality, low-noise audio recording or the optional XLR-K3M XLR Adapter Kit. Interval shooting for time-lapse videos as well as Full HD recording at up to 120 frames per second, slow motion and time-lapse and many other functions are also available.

Optimization of construction, design and customization options

The design and operating options of the new Alpha 7R IVA have been revised. Many of the wishes of the Sony professional community have been taken into account.

The Alpha 7R IVA has been further optimized for maximum resistance to dust and splash water. All connection points on the housing, the battery compartment cover and the media slots have been additionally sealed. In addition, the camera is made of an ultra-light and ultra-resistant magnesium alloy and is equipped with a revised extra-firm lens mount with six screws.

Other improvements to the body design include a redesigned grip that fits better and more securely in the hand, a larger diameter and optimized feedback of the AF ON button, a redesigned multi-select joystick for spontaneous control, a lock button for the exposure compensation dial and a new shape and position of the rear dial. At the request of many professional photographers, the new camera is also equipped with two UHS-II compatible media slots, which expand the general range of functions and enable faster read/write operations.

The options for saving settings have been expanded for greater ease of use. Almost all camera settings can now be saved to and loaded from a memory card. Up to 10 combinations can be stored on one card and loaded into any camera body of the same type.

Despite the 1.5x pixel count, battery life has also been improved - with a CIPA measurement of up to 670 shots (via LCD, 530 shots via electronic viewfinder) per charge. To further extend the operating time, the optional VG-C4EM vertical grip holds two NP-FZ100 batteries and the optional multi-battery adapter (NPA-MQZ1K) can hold up to four Z batteries. The housing can also be supplied with power via the USB port.

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 low-light photography, 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.
