Sony A7M4 micro single new detail exposure 1 sec continuous shooting 20 supports dual card slot.

Sony Sony A7 III micro camera has been launched for more than three years, and it was also reported earlier. Sony A7IV has been put on the agenda. Recently, foreign media have also exposed more new news about this camera. The fuselage still maintains a compact and lightweight design, and the all-magnesium alloy fuselage is dust-proof and drip-proof. Moreover, according to the law that Sony released a new micro-single before, Sony A7IV still uses a 24-megapixel back-illuminated sensor. Using BIONZ X image processor, the overall data processing performance of the camera is improved through algorithm optimization.

The fuselage supports dual SD card slots and 5-axis anti-shake, which is convenient for material storage. At the same time, sports and shooting can also provide 5.5-speed anti-shake compensation effect. Touching the flip screen will further optimize and the actual shooting experience will be better. In terms of taking photos, the sports continuous shooting has increased to 20 photos per second. At the same time, the brand-new 693-point hybrid autofocus system makes the human eye detection focus quieter and faster, and almost does not run out of focus. As for the performance of video shooting, there are many new highlights. It supports the recording specification of 4K/60fps at most, and there is some room for upgrading. If you shoot by hand, the 5-axis anti-shake fuselage and the late slow motion are still very practical. Switch to full HD, and you can shoot 120fps video every second. Freeze every wonderful moment is really a cinch.

But unfortunately, for colorful scenes, the 8-bit coding of 4:2:2 is very important. It is inevitable that color faults will appear in the later color matching. Shooting needs a little more thinking. However, the built-in S-Log3 gamma curve and HLG's wide dynamic range mode can also alleviate this problem to some extent. Photographers need to make some choices in shooting. As for other details, foreign media pointed out that Sony A7IV microphase is more likely to adopt a brand-new NP-FZ 100 lithium battery. The improvement of battery life should be no problem to meet the needs of one-day shooting. After all, the USB 3. 1 Type-C interface is reserved on the side of the fuselage, which can realize fast charging, and of course the data transmission will be faster and more stable. The specific release time is not clear for the time being, but it is very likely to be officially released at the end of 20021.
