Sony A7R IV: a quick overview of the full-frame mirrorless

Social networking users have already dubbed the new Sony Corporation a 61 megapixel bomb. After all, this is the first full-frame mirrorless camera with such a matrix on the world market. Sony A7R IV is significantly ahead of its competitors in technical specifications and functionality.

 

 

Canon and Nikon are also expected to bring their solutions to the market. Experts note that competitors have not had interesting new products for a long time. As a result, Sony was the first to “shoot”. And very well. After making a presentation of the camera and sharing the technical characteristics, the company representatives immediately announced the deadline for the sale of equipment and the preliminary price. The novelty will go on sale in September 2019 of the year, the starting price is 3500 US dollars.

Based on the specs, the Hybrid AF looks perfect. The video recording mode is very confusing. At 4K resolution, the frame rate limit is too high - 30p and 24p. It is a pity that Sony made such a mistake. After all, cameras of older models from competitors are able to shoot video with a frequency of 60 / 50r.

 

 

But tracking autofocus and 10 frames per second when taking pictures is an excellent indicator. Professionals will appreciate. Plus - the controllability of the device. Representatives of the company claim that the Mark III is not standing next to the Sony A7R IV.

 

 

The novelty has a multi-mode with pixel shift. By combining 4 images with full color data or 16 images with sub-pixel offset, you can create an 240-megapixel photo.

 

 

Sony A7R IV electronic viewfinder, in comparison with its predecessor, has an OLED display with 5,76 millions of dots per inch. Rumor has it that Sony "stole" the viewfinder from Panasonic. At least on the S1 and S1R models, the same viewfinder. For users with trembling hands, 5-axis stabilization is provided during shooting.

 

Updated version of Sony A7R III

Like its predecessor, the Sony A7R III, the camera is very compact and lightweight. Technologists have worked on the ergonomics of the case. The novelty made a deeper grip of the handle. Now holding the device in one hand is much more convenient, even with a large lens.

 

 

They added a lock on the exposure compensation scale, which the photographer on the Sony A7R III constantly knocked down with his finger. Improved the buttons and the joystick - a great damping feel when pressed. Pleased with the protection of the camera body from dust and moisture.

 

 

Sony abandoned the traditional microphone. Now the Sony A7R IV camera has its own analog-to-digital converter. This is a bold plus for the news. Before digitizing the sound signal, the technique is able to eliminate noise, apply effects and perform processing with user settings.

 

 

Another flaw was added to the flaws with shooting video in 4 format. There is no RAW editor in the camera. For image processing, you have to transfer photos to a computer. Plus, in the settings, the user will not find presets for the RAW format images themselves. For example, reduce the resolution for an uncompressed photo. Fortunately, the flash drive market is ready to provide a large card.
