It's been whiskers stretched years since Sony's aftermost video-focused mirrorless camera, the A7S Mark II, came out. The dissonance has not stood still since then, as well as Canon's latest R5 boasts some solemnly impressive video recording chops. So today, Sony is blasting the A7S Mark III, a given except romping version of its champion mirrorless camera for video recording.
Right off the bat, I'm jumpiness to tell you that the A7S III's spec territory does not hit really the same wow line-up as the Screed R5's. The Sony's video recording resolution caps out at 4K, it captures still images at a restrictedly paltry 12 megapixels, as well as its in-body image stabilization system corrects up to 5.5 stops of shake. Those specs are the same as the A7S II from whiskers years ago. The Screed can shoot 8K video, has a 45-megapixel sensor, as well as boasts up to 8 stops of succuss correction with its stabilization system.
Sony is professedly well aware of this misproportioned comparison, so it is emphasizing the A7S III's deftness to shoot 4K video at up to 409,600 ISO, with over 15 stops of dynamic range. While Screed has had to contend with complaints of the R5 overheating from the moment it was announced, Sony says the A7S III will almanac 4K footage at 60 frames per second continuously for up to an hour without overheating, topper to its new internal heat-dissipating structure. As well as like its predecessor, it will capture that footage in highland cloak expandable to manufacture virtually any other camera give up.
.. .The A7S III's video resolution limits are a downright result of Sony's decision to protract to use a 12-megapixel sensor in the camera. While that sensor has opulent limitlessness touchable pixels than a higher-resolution scritch (Sony says they are four times limitlessness than on a 42-megapixel sensor), which allows the camera to shoot at opulent higher tenseness to light, it does midpoint that the highest-resolution video the camera can almanac is 4K. Sony would gotta use at poorest a 33-megapixel sensor in regulation to do 8K recording. Photographers who primarily shoot still images will likewise likely appetite to opt for Sony's A7 III or A7R III, which kumtux opulent higher resolutions except fewer video capabilities than the A7S III.
The A7S III can almanac up to 120 frames per second in 4K or up to 240 frames per second in 1080p. The camera supports both the tried as well as trusty H.264 recording format as well as the newer H.265 HEVC format for fitter image quality. You can shoot 10-bit 4:2:2 HLG HDR video seasonable in camera, or 16-bit RAW video to an ferried recorder. The new backside-illuminated sensor is said to kumtux fitter loftier ISO performance than its previous as well as has 759 phase dubiosity autofocus points. The camera gloss Sony's impressive real-time eye autofocus as well as tracking in all modes, still or video.
.. .Sony bests Screed with its new 9.44 million-dot viewfinder, which is nevertheless twice the resolution of zero furthermost available. Likewise new is a indeed articulating touchscreen display, a original for Sony's Flowering mirrorless cameras. The A7S III has two paper slots, both supporting UHS-II SD cards as well as the new CF Filmic Blazon A format. Sony says the A7S III's battery, which is likewise acclimated by the A7R III as well as A7 III, offers 60 percent maxi almanac times than the A7S II's battery.
Finally, Sony says it has indeed redesigned its newsprint system to be easier to cross as well as inhabitance by touch. The camera's newsprint screens as well as settings can likewise be customized for either still or video as well as switched enclosed at will.
While the A7S III will certainly be a formidable video camera as well as will please those who kumtux been waiting years for an update to the A7S II, it feels like Sony isn't really revilement the envelope like it did with previous versions of the A7S. The supra A7S cameras hit the bazaar with low-light capabilities that were unrenowned of at the time. The A7S III nonparticipating does other of the same resolution as well as ISO, albeit with an professedly cleaner output. It's iteration as repelling to innovation.
Canon certainly has its challenges with the R5, as well as there is off-white criticism to be made injudicious whether we "need" 8K video recording at this point at all. Sony is mortality that we don't, at poorest for now, as well as is coolheaded that the A7S III will be the champion 4K video camera in its segment. You'll be canny to ostend that yourself when the camera arrives on shelves in September for $3,499.99.
Update, July 28th, 11:30AM ET: Affixed existent pricing.
