Sony a7S III: an upcoming full-frame camera now touted to have a flip-out rear screen and a world-beating EVF
Recently, a senior executive from Sony's Digital Imaging Group confirmed that, after a wait of about 5 years, the a7S III is finally a reality. This successor to the original low-light champion will apparently come with a complete re-haul, internally at least. According to some recent leaks, this may indeed be the case. For example, an image posted to SonyAlphaRumors suggests that it will look rather like the a7R IV this time around.
It may also feature an even more up-to-date design tweak of Sony's: a rear screen that flips out rather than up (as seen on another 2020 release, the ZV-1 "vlogging camera"). The leaked "a7S III" image also indicates a new kind of SD card release mechanism, by which the user slides a button downwards to get at this storage medium.
On that note, the a7S III is also now said to support UHS-II cards. Its new sensor is thought to have a resolution of 12MP and to be of the stacked CMOS variety. This may enable the camera to shoot 1080p video at 240 frames per second (fps); 4K at 120fps (not to mention in 10bit and 4:2:2 color) and 4K/120fps in RAW over HDMI.
Therefore, it may compete effectively with the recently-launched Canon EOS R5. This camera is now said to fall behind its impending alpha-series threat in that the latter may not be subject to the overheating that reportedly plagues the former.
Indeed, the EOS' recording time is reportedly limited to 29 minutes and 59 seconds in all modes thanks to this issue. In fact, one online camera enthusiast now asserts that the new Canon may only last out for as little as 15 minutes in certain non-optimal conditions (most notably increased temperatures and sub-par lighting), with the exception of its 4K/30fps mode.
Furthermore, the a7S III may also beat the R5 in terms of EVF. The latter has one composed of 5.76 million dots, whereas the upcoming Sony is now believed to have no less than 9.4 million. Should this leak prove valid, this would make it the highest-resolution EVF on Earth at its launch. The same new unit is slated to do so at the end of July 2020: therefore, we may not have long to wait to confirm all these possible specs.
