Sony Alpha ILCE-7R IVA Body

The highly versatile and capable Alpha 7R IVA is Sony's highest resolution camera to date. It offers impressive image quality with high resolution and wide dynamic range with consistently outstanding focus performance, high-speed continuous shooting, and many other features.

These include the world's first rear-exposed Exmor R CMOS 35mm full-frame image sensor with 61 MP and latest-generation BIONZ X image processor, real-time focus with eye detection for movie shooting, and advanced real-time tracking plus real-time AF with eye detection for still photography and APS-C cropped mode at an impressive 26.2 MP resolution. The camera supports advanced networking and operability for high-speed WiFi, remote wireless PC networking, wireless FTP transfer, or faster USB data transfer. The Alpha 7R IV allows professional 4K movie shooting with full pixel display without pixel binning in Super 35mm mode. At the same time, it features S-Log 3 and support for HDR workflows. When used with Sony's new microphones with XLR adapters, the Multi Interface Shoe with digital audio interface delivers high sound quality recordings.

A new dimension in image quality

The Alpha 7R IVA is equipped with a newly developed rear-exposed 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-stop 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 color reproduction.

This new full-frame model incorporates an innovative 5-axis image stabilization system optimized for this camera's high-resolution shooting capabilities, enabling a shutter speed advantage of 5.5 stops. 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 Sony camera: an electronic UXGA OLED Tru-Finder with 5.76 million pixels. That's about 1.6 times the resolution of the Alpha 7R III's electronic viewfinder, so this new viewfinder renders every subject ultra-accurately and true to life. Standard or high display quality and a frame rate of 60 or 120 frames per second can be set for optimal adaptation to the subject and shooting conditions.

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

Shooting and focusing speed

The innovative new Alpha 7R IVA full-frame mirrorless camera can shoot at up to 10 frames per second with consistently accurate AF/AE tracking for approximately 7 seconds - each at full resolution - in full-frame 61 MP (JPEG/RAW) or approximately 3x as long in APS-C sized 26.2 MP cropped mode. These high-speed capabilities capture even fast-moving subjects with ultra-accuracy and impressive detail.

The Alpha 7R IVA's advanced focusing system includes 567 AF phase detection points covering approximately 74% of the image area, plus 425 AF contrast points for added accuracy and reliability in low-light and other shooting situations for which contrast AF is ideal. The new camera's higher AF sensor density and revised tracking algorithms significantly improve tracking performance, so even complex or sudden subject movements are now tracked reliably and more 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, enabling ultra-accurate focusing of 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. In addition, a real-time tracking function is available that uses a newly developed subject detection algorithm to provide even more precise subject tracking and continuous focus system tracking. Anti-flicker shooting mode automatically detects fluorescent and artificial lighting and minimizes corresponding effects on the final image.

Optimized networking for professional workflows

The new Sony Alpha 7R IVA full-frame camera is equipped with a range of advanced networking features for professional workflows. The new model offers WLAN with support for the usual 2.4 GHz band, as well as the 5 GHz high-speed band, for faster and more stable data transfer. A wireless PC remote 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 around unhindered.

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 that supports ultra-fast data transfer, nearly doubling the data transfer rate over the Alpha 7R III when combined with Imaging Edge software. The camera also features FTP data transfer, which sends images to a specified FTP remote server while images are still being captured or viewed.

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 their PC screen. "Viewer" lets users quickly preview, rate and select photos, even in large libraries. With "Edit", high-quality images can be created from RAW data.

For the most straightforward image transfer possible, with the latest version of the Imaging Edge Mobile application from Sony Images can now be transferred to a connected smartphone even when disconnected from power.

High-resolution 4K and pro movie features

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 provide highly flexible color shaping, and S-Log 3 offers up to 14 levels of dynamic range. HLG (Hybrid Log-Gamma) is also available with the Alpha 7R IVA to support direct HDR workflows.

For video autofocus, this versatile new full-frame camera uses an optimized fast hybrid autofocus system that speeds up autofocus while filming and makes it more seamless and stable - even when an object temporarily moves in front of the subject. The Touch Tracking function for movie shooting also captures the desired subject with just a touch of the display.

The Alpha 7R IVA is the first Sony camera to feature real-time AF with eye detection for movie shooting. When this function is activated, the eye of the subject in question is automatically tracked ultra-precisely and ultra-reliably, allowing the filmmaker to focus entirely 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 noteworthy 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. In addition, interval recording is available for time-lapse video, as well as full HD recording at up to 120 frames per second, slow motion and fast motion, and many other features.

Optimized construction, design and customization options

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

The Alpha 7R IVA has been further optimized for maximum resistance to dust and splash water. For this purpose, 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-lightweight and ultra-durable magnesium alloy and features a redesigned 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, larger diameter and optimized feedback for the AF ON button, redesigned multi-select joystick for spontaneous control, a lock button for the exposure compensation dial, and a new shape and position for the rear dial. In response to requests from many professional photographers, the new camera is also equipped with two UHS-II compatible media slots that expand the overall feature set and enable faster read/write operations.

For greater ease of use, the options for saving settings have been expanded. 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 1.5 times the number of pixels, 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 operating time, the optional VG-C4EM vertical grip houses two NP-FZ100 batteries, and the optional multi-battery adapter (NPA-MQZ1K) can accommodate up to four Z batteries. In addition, the body can be powered via the USB port.

Sigma 105mm f2.8 DG DN Macro (A) for Sony-E

The SIGMA 105mm F2.8 DG DN MACRO Art is the first macro lens specifically for mirrorless cameras in our Art product line.

This medium telephoto macro lens offers excellent resolving power, with wonderfully soft bokeh.

Impressive image results thanks to sophisticated optical corrections

The innovative optical design of the 105mm F2.8 DG DN MACRO Art ensures excellent sharpness and fine reproduction at all shooting distances, from macro to infinity. It also achieves clear images without color fringing. This is achieved, among other things, by paying special attention to the correction of longitudinal chromatic aberration. Longitudinal chromatic aberration cannot be corrected by the camera's own aberration correction.

Another focus in the development of the 105mm F2.8 DG DN MACRO Art was placed on bokeh, which plays a particularly important role when shooting in the medium telephoto range. The large yield of ambient light creates beautiful out-of-focus circles, while the natural bokeh in the foreground and background adds incredible flexibility to photographic expressions.

Highest optical and AF performance

Optical performance is a top priority in the design of lenses in the SIGMA Art product line.

Through consistent development work, Sigma has managed to excellently handle coma, for example, an aberration that often occurs at the edges of the image. In addition, ghosting and reflections are highly minimized. This was achieved through rigorous testing at early stages of development and ensures that optical performance is excellent even when backlit.

In addition to being optimized for the latest features, such as face/eye detection AF, which mirrorless camera systems are very good at, the lens is equipped with a powerful Hyper-Sonic Motor (HSM) that ensures highly accurate and quiet AF operation.

Ghosting and reflection minimizing design

An ideal lens directs incident light through all the lenses and onto the sensor. If, on the other hand, some of the light is reflected by individual lenses, not only does the light yield decrease; the reflections within the lens create ghost images and aperture spots, or they reduce contrast. Such effects would be particularly noticeable in backlit shots.

To prevent this, the Sigma 105mm F2.8 DG DN MACRO Art uses a Super Multi-Layer Coating (SML) that reduces flare and ghosting. The result is clear, sharp, high-contrast images without distracting lens flares.

Compatible with the latest full-frame mirrorless cameras.

The SIGMA 105mm F2.8 DG DN MACRO Art is compatible with full-frame mirrorless cameras with Sony E-mount.

An HSM motor is used for fast focusing. Auto focus with automatic eye detection used in newer mirrorless cameras is also supported; making precise focusing of portraits, for example, a breeze.

Effortless operation for maximum creativity

A wide range of features and excellent build quality make the 105mm F2.8 DG DN MACRO Art a pleasure to work with.

The lens has a focus range limiter, which is extremely handy for macro shooting as you can preselect or narrow down the AF working range. In addition, the lens has an AFL button that the photographer can assign specific functions to.

The manual aperture ring on the lens can be used optionally, is intuitive to use and also very functional. For example, the aperture ring click switch can be used to make the aperture ring click at each aperture stop or not, if it is not desired for background noise in macro shots of insects, for example. There is also an aperture ring lock switch. Thanks to all these advanced features, photographers can optimally adapt their working style to their shooting style.

The 105mm F2.8 DG DN MACRO Art is also dustproof and splashproof, so it can easily be used in harsher shooting conditions. All rings and switches, in turn, feature particularly durable construction, excellent operability and a comfortable grip.
