Topaz Labs' flagship app uses AI algorithms to make some complex image corrections really, really easy. But is there enough here to justify its rather steep price?
Sony has introduced the a7R IV, which the company calls 'another milestone in mirrorless', at an event in New York City.
The camera has a full-frame 61MP BSI-CMOS sensor with a claimed 15 stops of dynamic range (it's the first new sensor since 2015, according to Sony). It has a hybrid AF system with 567 PDAF and 425 contrast-detect point, and 74% frame coverage. There's also real-time eye, human and animal AF. The camera can shoot at 10 fps with continuous AF for up to 68 photos.
The body has been redesigned, with upgraded weather-sealing, including foam gaskets around the battery and card doors, and raised lips around all the connectors that, along with rubber port doors prevent water from working its way around the seal. There'a also a significantly deeper grip, a larger joystick and repositioned, 'newly designed' buttons and dials. There's also a 5.76M-dot EVF, dual UHS-II card slots and USB-C. The camera also has 802.11ac Wi-Fi plus Bluetooth and NFC.

The a7R IV uses the NP-FZ100 battery, which can take approximately 670 shots using the LCD and 530 using the EVF, based on CIPA standard testing. A battery grip, which holds two FZ100s, is priced at $400.
As with its predecessor, the a7R IV has built-in 5-axis image stabilization, which can reduce shake by up to 5.5 stops, according to Sony. It has the same Bionz X processor and tilting 1.44M-dot touchscreen display as the Mark III.
If you drop down to APS-C crop mode you get 26 Megapixel images, with near-total-frame AF coverage and 325 PDAF points.
The Pixel Shift mode can captures 960 Megapixels worth of data by compositing 16 images, which can be processed via Sony's Imaging Edge software to create 240MP photos. Users have a choice of 16-shot mode that makes 1/2 pixel shifts or a 4-shot mode that makes full pixel shifts. Using the 1/2 shift mode you get twice the spatial resolution and full color at each pixel, while the full shift mode (which uses 4 images) just cancels out the Bayer filter.
The a7R IV can capture oversampled 4K/30p video with touch tracking and real-time Eye AF, and support for 8-bit S-Log2/3 and HLG. When using the Super 35 crop there is an additional 1.2x crop at 30p and 1.1x at 24p. As with its predecessor, the top bit rate is 100Mbps using XAVC S.
There's also a new digital interface between the the microphone and camera, making the a7R IV the first camera to accept digital audio input. To go along with that there's a new microphone and an XLR adapter, both of which have built-in ADCs to provide digital signal to the camera (but which also have analog output modes to retain compatibility with older cameras). You can read more about those here.
The camera includes new connectivity options, thanks to the addition of 5GHz Wi-Fi. Wi-Fi can now be used for tethered shooting as well.
The a7R IV will ship in September for $3500.
NEW YORK — July 16, 2019 — Sony Electronics Inc. today announced the latest addition to its acclaimed Alpha 7R series full-frame mirrorless camera line-up: the extremely versatile, powerful Alpha 7R IV (model ILCE-7RM4).
Sony’s highest resolution full-frame camera ever, the new Alpha 7R IV delivers stunning image quality with high resolution and wide dynamic range while maintaining outstanding focusing performance, high-speed continuous shooting and much, much more.
“We are continuing to drive innovation, break boundaries and redefine the expectations of digital camera performance,” said Neal Manowitz, deputy president of Imaging Product and Solutions Americas at Sony Electronics. “The new Alpha 7R IV combines medium format-level image quality with high-speed shooting, extremely fast focusing and an extensive list of upgrades to design, connectivity and usability. This will allow professional photographers, videographers and all other types of creators to capture content in ways that were simply not possible before.”
The new Alpha 7R IV features a newly developed 35mm full-frame, back-illuminated CMOS image sensor with a resolution of 61.0 MP[ii], the world’s first[i] of its kind. The new sensor’s back-illuminated structure and effective noise reduction techniques combine to deliver extremely low-noise and high-sensitivity performance, ensuring the absolute maximum image quality. The camera also boasts an impressive 15-stop[iii] dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights, and utilizes algorithms from many of the latest Alpha cameras to maintain outstanding color reproduction.
This new full-frame model is equipped with an innovative 5-axis, optical in-body image stabilization system that has been fine-tuned to support its high-resolution shooting capacity, resulting in a shutter speed advantage of 5.5-steps[x]. Additionally, the shutter unit assembly has been carefully redesigned to reduce even the slightest movement that may cause blur.
The Alpha 7R IV also includes Sony’s highest resolution viewfinder ever, a 5.76 million dot UXGA OLED Tru-finder EVF. About 1.6x the resolution of the EVF in the Alpha 7R III, this new viewfinder provides an extremely accurate, true-to-life depiction of the scene being framed. The display quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.
Additionally, the new camera features an evolved Pixel Shift Multi Shooting[xi] mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in one pixel or half-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels of data, which are then composited into a 240.8 million pixel (19008 x 12672 pixels) image using Sony’s “Imaging Edge™” desktop application[xii]. Ideal for photographing architecture, art or any other still life subject, this enhanced mode produces photographs with a level of detail and color accuracy that is simply stunning.
The innovative new Alpha 7R IV full-frame mirrorless camera can shoot full resolution images at up to 10 fps[iv] with continuous, accurate AF/AE tracking for up to approximately seven seconds[v] in full-frame, full-resolution mode (JPEG / RAW), and approx. three times as long in APS-C crop mode delivering 26.2MP[ii] images. These high-speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.
The upgraded focusing system of the Alpha 7R IV is comprised of 567 focal-plane phase-detection AF points that cover approximately 74 percent of the image area. There are also 425 contrast AF points that add extra precision and reliability for low light and other situations that are best served by contrast AF. The higher AF sensor density and refined tracking algorithms of the new camera produce a notable improvement in tracking performance, allowing complex subject motion and sudden subject movements to be reliably tracked with greater precision than ever.
The Alpha 7R IV also supports Real-time Eye AF, which employs artificial intelligence to detect and process eye location data in real-time, locking and maintaining focus on the subject’s eye with extreme precision. This is available for both animal and human subjects, with either animal or human Eye AF mode selectable depending on the shooting situation. Real-time Tracking[vii] is available as well, which utilizes a newly developed subject recognition algorithm to ensure the ultimate subject tracking and persistence of the focusing system. There is also an anti-flicker shooting[xiii] mode, which automatically detects the presence of fluorescent or artificial lighting in a shooting environment to minimize any impact on the final image.
Sony’s new Alpha 7R IV full-frame camera is equipped with a variety of advanced connectivity features designed to enhance professional workflow. The new model includes wireless LAN functionality to support the conventional 2.4 GHz band, as well as a high-speed 5 GHz[xiv] band for faster, more stable data transfer. Wireless PC remote connectivity (wireless tethering shooting)[viii] is also available on the new Alpha 7R IV, a first for Sony cameras. Requested by many working professionals, this allows for much more freedom in studio and location shoots, letting the photographer move around freely and without restriction.
In addition to high-speed Wi-Fi® and wireless PC connectivity[viii], the new full-frame camera is equipped with a SuperSpeed USB (USB 3.2 Gen 1) USB Type-C™ connector that supports extremely fast wired data transmission, with almost doubled data transfer speed achieved in combination with Sony’s Imaging Edge software (compared to the Alpha 7R III). It also supports FTP data transfer with background transfer capability, allowing photographers to send images to a specified FTP remote server while they are still shooting or reviewing images.
To support an efficient, high-speed, connected professional workflow, Sony has announced version 2.0 of its “Imaging Edge” desktop applications (‘Remote’/’Viewer’/’Edit’)[xiii]. The ’Remote’ application allows users to control cameras and monitor live shooting on their PC screen; the ‘Viewer‘ application is used to quickly preview, rate and select photos from large libraries; and the ’Edit‘ application can develop RAW data into high-quality photos for delivery.
To maximize convenience in image transfer, when utilizing the latest version of Sony’s Imaging Edge Mobile™ application[xv], the camera can now transfer images to a connected smartphone even if the camera’s power is set to OFF[xvi].
In addition to its impressive still image capabilities, the new Alpha 7R IV performs exceptionally well as a serious filmmaking tool, offering 4K (3840x2160 pixels) video recording across the full width of the image sensor, and full pixel readout without pixel binning in Super 35mm mode[ix]. This ensures high-quality 4K footage with exceptional detail and depth. S-Log 2 and S-Log 3 are also available to maximize color grading flexibility, with S-Log 3 offering a total of 14-stops of dynamic range. Hybrid Log-Gamma (HLG)[xvii] is also available on the Alpha 7R IV to support an Instant HDR workflow.
For video autofocus, the versatile new full-frame camera utilizes a refined Fast Hybrid AF system that achieves faster, smoother, more stable autofocus during video shooting – even if an object temporarily moves in front of the intended subject. The camera also includes Touch Tracking functionality during movie shooting, allowing the user to simply touch the screen on their intended subject for instant acquisition.
The new Alpha 7R IV debuts Real-time Eye AF for movie shooting, a first in any of Sony’s cameras. When activated, the eye of a subject is automatically tracked with high precision and reliability, allowing the shooter to focus on the content itself as opposed to what is in focus or not. The aforementioned Touch Tracking functionality will also automatically initiate Eye AF when a human subject is selected.
Another notable video feature is the addition of a digital audio interface to the camera’s Multi Interface Shoe™ (MI Shoe), allowing a direct, digital connection from the new ECM-B1M Shotgun Microphone or XLR-K3M XLR Adaptor Kit for clear, low-noise and high-quality audio recording. Interval shooting for creating time-lapse videos is available, as well as full HD recording at up to 120 fps, Slow and Quick Motion[xviii] functions and much more.
The new Alpha 7R IV has several upgrades to its design and usability, with many adjustments being implemented directly from the voice of Sony’s professional community.
To maximize durability, the new Alpha 7R IV features upgraded dust and moisture resistance[xix], with additional sealing provided at all body seams, battery compartment cover and media slots. The camera is built with an extremely lightweight and durable magnesium alloy and also has an upgraded six screw, extra-firm lens mount.
Additional enhancements to the body design include an improved grip for greater comfort and a more sure hold within the hand; an increase in the diameter and feedback for the ‘AF-ON’ button; a new multi-selector joystick design for improvised control; an exposure compensation dial lock button; and a redesigned shape and new position for the rear dial. A strong request from many professional users, the new camera also includes two UHS-II compatible media slots, allowing for higher overall capacity and faster read/write speeds.
For added convenience, camera setting registration is expanded. Now, almost all camera settings can be saved to, and read from, an inserted memory card. Up to 10 combinations can be saved to any individual cardand loaded into any camera body of the same model.
Despite its increased pixel count compared to the Alpha 7R III, the battery life has been improved with a CIPA measurement of up to 670 still images per change using LCD monitor, or 530 images with EVF. For even more uninterrupted operating time, the new optional VG-C4EM Vertical Grip holds two NP-FZ100 batteries, and the optional Multi Battery Adaptor (NPA-MQZ1K) can hold up to four Z batteries. The body can also be powered via the USB connector[xx].
Sony has also released a variety of new accessories to compliment the new Alpha 7R IV camera, including:
