With 61 million pixels Sony A7R4 The release of the full-frame mirrorless camera has been confirmed by many rumors exposed before. Earlier news said that Nikon has ordered a batch of 61-megapixel full-frame image sensors with the model IMX455 from Sony. The phase detection autofocus speed of this image sensor is faster than Nikon D5 and D500. But Sony will not use the IMX455 image sensor, but will use the IMX455 improved IMX555 sensor. In addition, the Nikon Z8 mirrorless camera is likely to be launched in the third or fourth quarter of 2019, while the Nikon D860 SLR camera is expected to be released in early 2020. Both high-resolution cameras are expected to carry a 61-megapixel full-frame image with the model IMX455. sensor.
Then, come again Back to the more controversial topic in early July of this year: Is Nikon’s over-reliance on Sony image sensors reliable? In an interview with foreign media, the staff of Israeli semiconductor manufacturer Tower Jazz believed that Sony is not only an image sensor manufacturer, but also a camera manufacturer. If other camera brands that purchase Sony image sensors compete with Sony, Sony will have more advantages, while Nikon and other brands may be “stuck”.
is the current situation From a point of view, Nikon is very likely to purchase a “castrated version” of a 61-megapixel full-frame image sensor. If the news is true, all Nikon can do is to fully squeeze the maximum potential of this “castrated version” of the image sensor to maximize its performance. In addition, from the currently exposed Sony IMX455 image sensor data, this “castrated version” sensor also has quite good performance.
