Sony Electronics’ Alpha 7 IV Goes Beyond ‘Basic’ with 33-Megapixel Full-frame Image Sensor and Outstanding Photo and Video Operability

Sony Also Announces Two New Flashes to Evolve the Powerful Alpha Lighting System

San Diego, CA – October 21, 2021 – Sony Electronics Inc. today announced three new additions to its imaging line-up: the Alpha 7 IV interchangeable-lens camera (model ILCE-7M4) with a newly developed 33-megapixel (approx.,effective) full-frame image sensor, as well as two new flashes – the HVL-F60RM2 and HVL-F46RM.The Alpha 7 IV takes “basic” to the next level for full-frame cameras with excellent image quality and performance, redefining the lofty standards set by the acclaimed Alpha 7 III.  The new model features many of Sony’s most advanced imaging technologies, including the latest BIONZ XR™ processing engine and advanced AF (autofocus) capabilities from the flagship Alpha 1 combined with streamlined operability and enhanced reliability for photos and movies, making it the perfect all-around camera for today’s imaging enthusiasts and professionals. The Alpha 7 IV also boasts a 33MP (approx., effective) image resolution, rich movie expression and various features to support the growing demand for remote communication, bringing new meaning to what a “basic” camera can accomplish.“Since its introduction over three years ago, the Alpha 7 III has made tremendous impact in our industry, completely redefining the expectations for what can be accomplished with a ‘basic’, or entry-level full-frame camera,” said Yang Cheng, Vice President, Imaging Solutions, Sony Electronics Inc. “Now, it’s time to break through all existing boundaries again. The Alpha 7 IV brings together the best of Sony imaging technologies in both photo and video to deliver a high-end experience to a wider range of customers.  This gives today’s creators a new level of freedom to capture, create and share in ways that they’ve never been able to before, no matter the situation in which they find themselves.”

Alpha 7 IV: Innovation Never Ends

The new Alpha 7 IV is an exceptional hybrid camera packed with outstanding still image quality and evolved video technology with advanced autofocus, enhanced operability and improved workflow capability. The model was developed with the environment in mind by using Sony’s original recycled plastic SORPLAS™ for the camera body and packaging with recyclable[i] materials and less plastic.

Outstanding Image Quality

Thanks to a newly developed 33MP (approx., effective) full-frame back-illuminated Exmor R™ CMOS image sensor, superior image quality and Wide ISO sensitivity range expandable to ISO 50 – 204,800 is achieved. The high resolution enables the Alpha 7 IV to express smooth gradation, fine details and textures of the subject while reducing noise, and its 15-stop dynamic range allows a wide expressive range while Creative Look settings can help create original looks effortlessly for both stills and video.

Next-Level AF performance

The latest BIONZ XR™ processing engine is the same that is used in Sony’s flagship Alpha 1, delivering high-speed AF, uninterrupted continuous shooting up to 10fps[ii] with AF/AE tracking and a large buffer for a prolonged shooting experience. The 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 Alpha 7 IV also has face and eye detection accuracy for humans that is improved by approximately 30% compared to the Alpha 7 III.

Evolved Movie Technology

The Alpha 7 IV inherits technology taken from real-world movie production, including the S-Cinetone™ picture profile adopted from Sony’s highly regarded Cinema Line cameras.  This delivers a rich, cinematic look that has become popularized by a broad range of cinematographers and filmmakers who are shooting on Sony.  High quality movie is achieved with 4K 60p recording in Super 35mm mode and up to 4K 30p recording with 7K oversampling is available in full-frame mode. The new camera also features 10-bit depth 4:2:2 color sampling to enable natural gradation, XAVC S-I™ intra-frame encoding for more efficient editing workflows and XAVC HS™ H.265 long-GOP for doubled compression efficiency.

To meet the growing need for precise autofocus 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 visualizes 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 video camera with outstanding operability and reliability that easily allows the user to switch from photo to video and back at their convenience. New to Sony’s lineup of Alpha cameras is a dual-layer mode dial, with a lower layer for selecting Still/Movie/S&Q and a 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 stabilization for a 5.5-step[v] shutter speed advantage, 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, benefiting users with an upgraded live-view image quality that minimizes false color 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 stabilization further stabilizes movie shooting. They can also benefit from the 3-inch (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 minimizing its weight. In addition, the redesigned structure and lens lock button contribute to enhanced dust and moisture resistance[vii].

Canon Patent: TS-E Macro Lens (might be the TS-E 90mm F2.8L Macro)

Canon Patent

A new Canon patent was spotted by It’s for a tilt-shift lens and it might apply to an already released Canon lens.

Canon patent application 2021-167982 (Japan) discusses optical formulas for a tilt shift macro lens. The patent literature hints at an already released lens, the Canon TS-E 90mm f/2.8L Macro. From the patent literature:

PROBLEM TO BE SOLVED: To obtain an imaging optical system which has less aberration fluctuation during focusing from infinity to a short distance, has high optical performance over the entire focus range, and can easily secure a sufficient amount of peripheral light.

In recent years, an imaging optical system used in an imaging device such as an interchangeable lens still camera has a large aperture ratio, little aberration fluctuation during focusing from infinity to a short distance, and has high optical performance over the entire focus range. Is required.

The double-Gauss type imaging optical system is characterized in that it is easy to make a large-diameter ratio and the aberration fluctuation with respect to the fluctuation of the object distance is relatively small. However, in a double Gauss type imaging optical system, if the entire system is moved during focusing from infinity to a short distance, the amount of movement of the pupil increases. As a result, when trying to secure the peripheral illumination over the entire focus range, the effective diameter of the lens increases and the entire system becomes large.

In order to have a large aperture ratio, high optical performance when focusing from infinity to a short distance, and to obtain a sufficient amount of peripheral light, it is important to appropriately set the lens configuration, the material used for each lens, and the like. Will become.

Thepresent invention is an imaging optical system having little aberration fluctuation due to focusing from infinity to a short distance, having high optical performance over the entire focus range, and easily securing a sufficient amount of peripheral light, and an imaging apparatus having the same. The purpose is to provide.

  • Focal length: 90.00
  • F value: 2.91
  • Image height: 34.00
  • Overall length: 132.06
  • Shooting magnification: 0.5

Canon Sued Because Printer Won’t Scan When Out Of Ink


Canon has been sued by a user who discovered that his Canon PIXMA MG6320 All-In-One printer can not be used a scanner when ink runs out.

A Canon customer filed a class action lawsuit alleging deceptive marketing and unjust enrichment by Canon, as Bleeping Computer reports:

While using his Pixma MG6320 printer from Canon, the plaintiff was surprised to discover that the “all-in-one” machine would refuse to scan or fax documents if the printer ran out of ink.

As ink is not necessary to perform scans or faxes, the argument is that the printer features should continue to work even if there is no ink in the device.

It seems not to be the first case that users complain with Canon about this weird fact. The answer by Canon’s consumer support has always been the same:

This is indeed rather disappointing. To use your PIXMA printer as a scanner you are forced to buy ink cartridges, even if they are not needed by the scanning process itself. Not nice, Canon.

The lawsuit was filed in New York and looks at least $5,000,000 in awards, exclusive of interest, fees, and litigation costs.
