Sony has introduced the a7R IV, which the company calls 'another milestone in mirrorless cameras. 

A New Level of Image Quality

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 KING OF FULL-FRAME SENSORS

The Alpha 7R IV features a newly developed
61 Megapixel back-illuminated image sensor, the first of its kind. This remarkable new sensor delivers 15 stops of dynamic range for the extraordinarily detailed rendition of subtle details, while tweaked & refined algorithms ensure pleasing colours and skin tones.

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'an 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.

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 capture 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 colour 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 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 a digital signal to the camera (but which also have analog output modes to retain compatibility with older cameras).

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.

SHOOTING AND FOCUSING SPEED

Combining 567 on-sensor phase-detect autofocus points with refined tracking algorithms, the Alpha 7R IV boasts extraordinarily sophisticated autofocus abilities, with real-time tracking and eye autofocus enabled for both still and movie recording. All of this is available for full-
speed 10fps image capture with AF.

UPGRADES & SECONDARY FEATURES

Sony FE 24-105mm f/4 G OSS Lens Details

A compact, lightweight comprehensive zoom

From 24mm to 105mm and F4 aperture throughout the zoom this high-performance G Lens offers consistently high image quality. In addition to outstanding optical performance, it features compact, lightweight design for portability and mobility befitting the E-mount system. Fast, precise AF and high reliability add to the broad utility of this fine zoom lens.

Excellent corner-to-corner imaging throughout the zoom range

Advanced optics achieve consistently high corner-to-corner resolution throughout the zoom range. Four aspherical elements effectively reduce aberration, while ED (Extra-low Dispersion) glass elements minimize chromatic aberration. A circular aperture and carefully controlled spherical aberration shape add expressive potential with beautiful, smooth background bokeh and natural highlights that complement outstanding in-focus sharpness and clarity.

A one-lens solution for mobile, versatile shooting

Excellent optical performance and a high zoom ratio are packed into a compact, lightweight only 663 grams (23.4 oz.). The compact lightweight design extends to E-mount bodies for outstanding system mobility and handling ease. This one high-performance lens lets you shoot a wide range of subjects and situations. A minimum focus distance of 0.38 meters (1.25ft.) and built-in optical image stabilization further enhance all-around versatility.

Constant F4 and fast, precise, quiet AF for stills and movies

A bright constant F4 maximum aperture throughout the zoom range keeps the brightness even when the focal length is changed. Sony’s Direct Drive SSM (DDSSM) AF drive system offers fast, precise, quiet focusing. And a precision optical design minimizes focus breathing. All of this makes the FE 24-105mm F4 G OSS an excellent choice for both stills and movies.

Professional reliability and operability

A fluorine coating on the front element prevents contaminants such as oils, grime, and water from sticking to the front of the lens, and makes them easier to remove if they do become attached to the lens surface. A dust and moisture resistant design and customizable focus hold button further contribute to professional operability and reliability.

ED glass enhances resolution and colour

Three ED (Extra-low Dispersion) glass elements strategically deployed in the lens’s optical path further enhance resolution by suppressing chromatic aberration. Excellent sharpness and natural colour reproduction are maintained right out to the image edges.

Clarity and contrast in any light

Sony’s original Nano AR Coating suppresses spurious reflections that can cause flare and ghosting in backlit and other challenging lighting situations, for consistently high contrast and clarity. Freedom from flare over a wide range of incident light angles provides greater framing and composing flexibility. (1. Nano AR Coating / 2.Glass / 3.Transmitted light)

A beautiful blend of sharpness and bokeh

In addition to a circular aperture design, precise control of the lens’s spherical aberration shape contributes to the stunning balance between sharpness and luscious bokeh that is a hallmark of the G Lens brand. The ability to combine high resolution and smooth bokeh in creative imagery affords vast expressive potential.

High reliability in harsh conditions

The overall design of this lens is dust and moisture resistant for extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions

Fluorine-coated front element

The lens’s front element features a fluorine coating that helps to prevent dirt and fingerprints from sticking, and make it easier to wipe dirt and fingerprints away if they do become attached to the lens surface.
