Sony Alpha 7R IV: From 61 to 240 Megapixels
The manufacturer officially presented the Sony Alpha 7R IV to the public in New York on Tuesday evening. With 61 megapixels on a full-frame sensor, the Sony Alpha 7R IV sets a new record. Image noise is still as low as usual up to ISO 32,000, but the dynamic range with up to 15 light values is very opulent. In spite of the high resolution, the Sony Alpha 7R IV achieves a brisk production frame rate of ten frames per second, but only 68 shots per series.
By the way, if you want to push it to the extreme, you should activate the pixel shift mode. The Sony Alpha 7R IV takes a total of 16 consecutive shots with the help of its integrated 5-axis image stabilizer. Using the free imaging software, the photos can be combined to a 240 megapixel image on the computer.
By the way: Those who screw an APS-C optic to the e bayonet of the Sony Alpha 7R IV or simply want to narrow the angle of view will get images around 26 megapixels in size and almost 100 percent autofocus field coverage. This corresponds to a higher resolution than all cameras up to APS-C sensor size that are still available. The absolute record is held by the Samsung NX1 with 28 megapixels. But as is well known, it has been out of traffic for quite some time.
Sony Alpha 7R IV: With A9 Technologies and Eye AF for Videos
So quickly back to the Sony Alpha 7R IV, which has a lot more to offer. For example the autofocus. A total of 567 phase autofocus fields cover 76 of the image field and come with technologies from the sporty top model Alpha 9. In particular, real-time eye recognition for humans and animals helps to easily keep the eyes in focus at all times. The Sony Alpha 7R IV now also offers this practical function for filming. The Sony Alpha 7R IV also sounds very promising for filmmakers with UHD video, which the DSLM uses 6K resolution and oversamples to calculate down, as well as HLG and S-Log2/3 for up to 14 light values dynamic range.
The new accessory shoe should also be exciting for videographers. The Sony Alpha 7R IV comes with a new multi-interface shoe that is compatible with the ECM-B1M directional microphone presented at the same time. Thanks to digital signal transmission, active noise reduction and three adjustable recording directions, the microphone promises to transmit a very clear sound.
Sony Alpha 7R IV: New case, exuberant extras
Other features of the Sony Alpha 7R IV include a 5.76 million subpixel extremely high-resolution OLED viewfinder and a foldable and also very sharp LCD touch screen. Two SD card slots with UHS-II speed, focus joystick, X-sync cable connection for studio flashes and WLAN are also located on board the magnesium housing, which is better sealed according to my own information. Speaking of improved: The Sony Alpha 7R IV has a redesigned handle curvature for a better feel. However, this requires the new battery grip VG-C4EM.
The bottom line is that the Sony Alpha 7R IV sounds like an impressive piece of camera that leaves nothing to be desired. In view of the extremely high resolution, however, the DSLM shouldn't be suitable for every photographer. And not at all because of the price: the system camera should cost around 4,000 Euro. By the way, the battery handle VG-C4EM should cost 450 Euro and the microphone ECM-B1M about 380 Euro. Camera and accessories will be available from September.
