Sony’s interchangeable-lens camera ALPHA 7 IV with newly developed 33- megapixel (approx., effective) full-frame image sensor and two new flashes, the HVL-F60RM2 and HVL-F46RM offers a full-frame camera with excellent image quality and performance. The new model features the latest BIONZ XR processing engine and advanced AF (autofocus) capabilities based on the Alpha 1 model. The ALPHA 7 IV also boasts 33 MP resolution, rich movie expression and various features.
“With the introduction of the Alpha 7 III, we set the baseline for what full-frame cameras should deliver and now it is time to redefine those boundaries,” said Yann Salmon Legagneur, Director of Product Marketing, Digital Imaging, Sony Europe. “The ALPHA 7 IV brings together the best of Sony imaging technology to deliver a fantastic experience in both stills and video, meaning that users will be able to capture exactly the content that they want, in whatever situation they find themselves in.”
ALPHA 7 IV: Innovation never ends
The new ALPHA 7 IV is the ultimate hybrid camera packed with outstanding still image quality and evolved video technology with advanced autofocus, enhanced operability and workflow capability. The model was also developed with environment in mind by using Sony’s original recycled plastic SORPLAS for the camera body and the packaging with recyclable[i] materials and less plastic.
With a newly developed 33MP full-frame back-illuminated Exmor R CMOS image sensor, superior image quality and Wide ISO sensitivity range expandable to ISO 50-204800 is achieved. The high resolution enables the camera to express smooth gradation, fine details and textures of the subject while reducing noise. Its 15-stop dynamic range allows a wide expressive range while Creative Look settings can help to create original looks effortlessly for both stills and video.
The latest processing engine BIONZ XR used in the flagship Alpha 1 delivers high-speed AF, uninterrupted continuous shooting at 10fps[ii] with AF/AE tracking and a large buffer for a smooth shooting experience. ALPHA 7 IV tracks subjects with tenacious Real-Time Tracking and 759 phase-detection AF points in a high-density focal plane phase-detection AF system that covers approximately 94% of the image area. Additionally, for the first time, Real-time Eye AF can now track birds and animals’ eye for both still images and movies, in addition to humans. The detection accuracy for human face and eyes is also approximately 30% more improved, compared with Alpha 7 III.
Evolved movie technology
The ALPHA 7 IV inherits technology taken from real-world movie production including S-Cinetone™ – adopted from Sony’s highly regarded Cinema Line cameras used by a broad range of filmmakers and content creators – to deliver a rich, cinematic look. High quality movie is achieved with 4K 60p recording in Super 35mm mode and up to 4K 30p recording with 7K oversampling in full-frame mode. The new camera also features 10-bit depth 4:2:2 colour sampling to enable natural gradation, XAVC S-I™ intra-frame encoding for more efficient editing workflows and XAVC HS™ for doubled compression efficiency.
To meet the growing need for precise AF performance when shooting videos, unique AF features are achieved when using the ALPHA 7 IV with a Sony E-mount lens, including AF Assist[iii] that supports focus transitions when using AF and Focus Map that visualises depth of field. For the first time in the Alpha series, the new camera features Breathing Compensation[iv] to combat focus breathing and maintain a consistent angle of view throughout focus changes and can be switched on or off.
Advanced operability as a genuine hybrid model
The ALPHA 7 IV is a hybrid still and movie camera with outstanding operability and reliability that easily allows the user to switch from photo to movie and back at their convenience. New to Sony’s line-up of Alpha cameras is a dual layer mode dial with the lower layer for selecting Still/Movie/S&Q and the top layer for Auto/P/A/S/M and MR (Memory Recall), enabling users to quickly select and switch between the dedicated settings. It also has 5-axis optical in-body image stabilisation for a 5.5-step[v] shutter speed advantage, as well as an improved grip for greater comfort and a CFexpress Type A compatible media slot to support media with faster writing and clearance. Additionally, the 3.68 million-dot (approx.) OLED Quad-VGA viewfinder is 1.6 times the resolution of the Alpha 7 III viewfinder, allowing users to benefit from the upgraded live-view image quality that minimizes false colour and increases resolution.
Videographers can record 4K 60p 10-bit 4:2:2 video continuously for more than an hour thanks to the camera’s heat-dissipating structure. Optical ‘Active Mode’[vi] image stabilisation helps optimum video shooting. They can also benefit from the 3.0-type 1.03 million-dot (approx.) side-opening vari-angle touch-panel rear LCD monitor, top-panel REC button and high-capacity Z-series battery.
The ALPHA 7 IV body is built with magnesium alloy to achieve a robustness while minimising its weight. In addition, the redesigned structure and lens lock button contribute to enhanced dust and moisture resistance.[vii]
