also revealed on the SonyAlphaRumors website about the specifications and release date of the Sony α7 IV camera.
According to the news: Sony’s new A7IV full-frame mirrorless camera has a dynamic range of 15 stops. At the same time, the specific release date of this camera is set in mid-October. If the global shortage of chips and sensors cannot be fundamentally improved, the conference may be postponed.
The focus of this news is that Sony’s sales department stated that the α7 IV has achieved a dynamic range of 15 stops through the combination of a newly developed 33-megapixel sensor and a new image processing engine. Of course, whether the specific indicators can reach this value requires actual testing to verify. The following are some of the known specifications of this new α7 IV mirrorless camera so far.
1. The release date will be released in October. Now the global semiconductor supply is tight. If there is no problem with semiconductor supply, it should be released on time.
2. The newly developed 33 million pixel back-illuminated stacked sensor is 9 million pixels more than the previous generation of 24 million pixel a7III, which will greatly improve the picture shooting.
3. The dynamic range of 15 stops is basically the same as that of the previous generation a7III. Can increase the pixel by more than 25% while maintaining a high dynamic range level, which represents Sony's cmos and processor, noise control, especially dark light noise suppression has been further improved
4. The video specification is to obtain 4K 30p video from 7K oversampling. This is undoubtedly a bit disappointing. Although this 4k is overtaken from 7k, the resolution should be better than that of a7sIII, but the frame rate of 4k30p is still a bit uncomfortable. Of course, the increase in frame rate means that the processor's capacity needs to be improved, and the cache and storage have greater requirements. For such a basic micro-single, it should be a bit unbalanced, so it still only provides 4k30p. It should also be a balanced result.If this model is too powerful, how can other machines such as a7rIV and a7sIII be sold?
5. 5.5 levels of in-body anti-shake is adopted. This should be a figure that can only be achieved with lens anti-shake. As a Sony user, the author is still very worried about Sony's body anti-shake.
6. Full-size HDMI terminal. Many cameras now have enhanced video functions, but for video functions, the 3-inch screen behind the camera is a bit too small. So in order to better observe the viewfinder, you need to connect with an external monitor. Then the most mature output port is the HDMI interface. Many cameras have an HDMI interface, but in order to fit the camera's size, a small HDMI interface is used, which finally results in a very fragile place for this interface and connection. The full-size version will undoubtedly be more stable and durable. So this is a very valuable interface.
7. UHS-II SD card and CFexpress card are used. SD card is the cheapest card, of course, the disadvantage is that the speed is too low. The CFexpress card is faster, but the price is faster. So Sony offers these two cards really kind.
Generally speaking, for a new machine of the manufacturer, it constantly reveals little by little information through the Internet. It seems that there is no need to advertise. It uses the same performance as fishing bait, revealing a little bit every time, to let Sony Fans are rushing like fish, maybe this has achieved the purpose of publicity?
