Sony has also improved focus speeds on the A7S III, and it partly puts this down to the sensor sensitivity performance, which enables the camera to identify subjects in lower light than sensors with inferior sensitivity. The Sony A7S's maximum shutter speed is 30 seconds and there's also a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 100. Of course, time and photo tech marches on, and it felt like no time at all before the a7 earned itself an upgrade in the form of the Sony Alpha 7 II. The sequel kept a lot of the components of its predecessor – if it ain’t broke, as they say – but with the principal addition of 5-axis image stabilisation. Designed to reduce image blur by compensating for camera-shake, this system will be familiar to anyone who has used the Olympus OM-D E-M1 or E-M5. By compensating not only for pitch and yaw movements but also vertical, horizontal and rotational movements, the system ensures better stabilisation than any in-lens system could hope to achieve. With the A7 IV, you’ll be able to shoot a wide range of subjects including fast-moving sport and action. Noise is also controlled well and the level of detail in images won’t disappoint.
Completing the top of the A7S is a second prominent dial for setting Exposure Compensation and a small button marked with C1, which as the name suggests can be customised to access one of the camera's key controls (it's handily set to Focus Point by default).Armed as it is with an accurate viewfinder and screen, plus zebra and live histogram views, there are few excuses for getting the exposure of video or stills wrong. On the whole, I found that the Multi Metering mode is a good default option and the exposure guides are useful keeping an eye on the highlights in case you need to use adjust the exposure, apply a little exposure compensation or tweak the variable ND setting.
Video resolution: 4K at up 120fps and 1080p at 240fps, 10-bit and 4:2:2 colour, 16-bit raw video over HDMI

Why only 12MP? That might seem like an incredibly low resolution in 2020, and if you're looking for stills-first hybrid camera if might be a deal-breaker. But this resolution brings two main advantages. Firstly, it means both cameras' pixels are very large, making them the finest low-light shooters around. The A7S's EVF system also performs very well indoors in low light, typically the scourge of most EVFs which have to "gain-up" to produce a usable picture, resulting in a noticeably grainier picture. The A7S doesn't suffer from this unwanted effect at all, making its electronic viewfinder the equal of and in many areas better than a DSLR's optical viewfinder. The truest testament to the A7S is that we almost exclusively used it by holding it up to eye-level, something that we wouldn't do unless the EVF was of sufficient quality. But Sony says that its electronic Clear Image Zoom function –which lets you get 2x zoom with any lens by intelligently creating pixels, rather than simply cropping – is very popular with pro filmmakers, and this function will also work with the FX3's zoom lever. 4. The FX3 has cooling fans for longer record times Sony has improved the handling of each successive model. Consequently, the A7R V’s handling is significantly better than the A7R’s and quite a bit better than the A7R IV’s. Sony’s most recent camera feature a touch-screen, but Sony only made full use of it with the A7R V. With the A7R IV and A7R III, it’s only really useful for zooming in and out of images or setting the AF point. Yes CDAF is particularly susceptible to underperforming with stopped down apertures (b/c of the need to hunt more), but I'd imagine so are PDAF systems. Isn't there a smaller phase difference between 'left-looking' & 'right-looking' on-sensor PDAF pixels at smaller aperture? Perhaps this is balanced with sharper overall detail for the phase difference algorithms? Still, though, I'd imagine there's some crippling due to less light.
According to Sony, the 3-inch vari-angle screen wasn’t a request for the A7S III, it was a demand. It’s certainly something I’ve mentioned on many occasions. However, Sony hasn’t given the A7C the A7S III’s revised menu structure or its excellent touch-control. Also as a 0.39-inch type, A7C’s viewfinder is also pretty small for a full-frame camera. While the specification improvements might not seem dramatic to some, the handling of the A7IV is dramatically enhanced. For a start, the electronic viewfinder has a nice boost in resolution as it’s a 3.69-million-dot unit rather than a 2.36-million-dot device, and it has a refresh rate of up to 120fps.The FX3 also has the same 13-hour maximum continuous recording time as the A7S III. All of which means that card capacities and battery life are likely to be more of a limiting factor than overheating. 5. The FX3 has built-in thread holes for accessories My friend I told you we are looping in nonsense here anything from NASCAR, IndyCar, F1, Dragsters IS RWD!
The 312megapixel images are a little soft straight out of the camera using the default creative style and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera sharpening level. The night photograph was excellent, with the maximum shutter speed of 30 seconds and the Bulb mode offering lots of scope for creative night photography. So when it comes to shooting 4k UHD in bright conditions at low ISOs, I’d say there’s little to choose between the A7s II and the A7r II so long as the latter is set to its APSC / Super-35 crop mode. Of course the major difference then is their respective field-of-view when fitted with the same lens: the A7s II films 4k using the full sensor width, so doesn’t crop the field of view. But in its APSC mode, the A7r II is applying a 1.5x field reduction that means for wide coverage you’ll need even wider lenses. The flip-side is if you shoot long, using an APSC crop will give you extra reach. Another benefit of using an APSC crop is the ability to use non full-frame lenses, or full-frame DSLR lenses via a Speed-Booster, giving you an extra stop in brightness to play with. Sony has often received criticism for the complexity of its mirrorless cameras’ menus. Obviously, with such a feature-rich camera as the A7S III, there’s still going to be a long menu, however, Sony has given the matter some serious thought and the menu looks to be better laid out than on previous cameras with better grouping of key features. As well as boosting the low-light performance and enabling a sensitivity range of ISO 40-409,600 for video, using this sensor and processing engine combination enables the A7S III to capture video with up to 15 stops or more dynamic range at low ISO settings and in S-Log.
Specifications
If you choose the XAVC S HD option, you can film 1080p at 24, 30, 60 or 120p for NTSC or 25, 50 or 100p for PAL, all at 50Mbit/s apart from the 120p / 100p modes which are offered at 60 or 100Mbit/s. These 120p / 100p modes allow you to slow the footage down by five or four times on 24p or 25p timelines respectively. Note to support any of the XAVC S modes, you’ll need an SDXC memory card. You can film 1080 between 24p and 60p using full-frame coverage or with an APSC / Super-35 crop. The 120p / 100p is only available with its own different crop. In keeping with the serious video focus, the a7S III joins the likes of Panasonic's S1H in offering a full-size HDMI connector. This is a much more durable connector that's much less likely to drop the signal if anything touches the cable. The A7S can also shoot 1920x1280 pixel video at 60p/50p/60i/50i or 25p/24p in the AVCHD format, and 1440x1280 or 640x480 pixels at 30fps in the MPEG4 format. There's the ability to change the EV level, white balance, metering, ISO speed, DRO/HDR, creative style and picture effect, plus various audio recording options. If you set the shooting mode dial to Movie, you can also choose from Program, Aperture or Shutter priority and Manual modes, giving you full control over exposure for both stills and movies. Sony says the A7S II remains targeted at those who need a mix of video and stills, like wedding photographers who don't need to make large prints, concert photographers and astrophotographers. For those kind of shooters, the A7S III's 4K video powers are important, but the FX3 is a camera that's really built around them.
