Just Announced: The New Sony A7R III and Two New Lenses
25 October 2017 | Category: General News
Sony has beefed up its A7 range, introducing the 42.4-megapixel A7R III, which adds a slew of new features including a 399-point phase detection AF system and 4K video recording.
The Sony A7R III uses a new 42.4-megapixel Back-Illuminated full-frame Exmor R CMOS sensor with ‘Evolved Image Processing’ which, coupled with the BIONZ X processor, makes the new camera nearly 1.8x faster than the A7R II. The sensor and processing power together help produce a native sensitivity range of ISO 100 to 32000, which can be expanded to ISO 50 – 102400 for still images. The A7R III also boasts a new 5-axis optical image stabilisation system that Sony says offers a shutter speed compensation factor of 5.5EV. The other standout feature are its 399 phase-detection AF points that cover 68% of image area, along with 425 contrast AF points.
Sony says the A7R III’s new AF system can lock focus in half the time that its predecessor did, even in low light, and its tracking is twice as accurate as the A7R II. The new Sony camera should appeal to photojournalists and sports photographers as it can shoot at 10fps for bursts of up to 76 jpegs or 76 raw files or 28 uncompressed raw files - all with full AF and exposure metering. 4K video recording is on board the Sony A7R III, as you would expect, and it offers full pixel readout with no pixel binning, Sony says. Sony has also tweaked the body design to include dual media slots and different options for storing content within them, such as separate JPEG / RAW recording, separate still image / movie recording and more. An improved battery also offers 2.2x longer shooting time, Sony says. For the full feature list, visit Sony’s website.
Also launched today was Sony’s new FE 24-105mm f/4 G OSS lens, which joins its E-mount range for full-frame cameras and covers the wide-angle to mid-telephoto range. The new lens has an optical design of four aspherical lens elements, two of which are high-precision AA (advanced aspherical) lenses. There are also three strategically located ED (Extra-low Dispersion) glass elements that work in combination with the aspherical lens elements to minimise chromatic aberration. The FE 24-105mm f/4 is also the lightest lens in its class, Sony says, at 663g. It’s also weather resistant and features Sony’s Nano AR coating to cut down on flare and ghosting.
Finally, Sony rounded out the day announcing the development of a new flagship G Master lens. The company says it intends to launch a new FE 400mm f/2.8 GM OSS super telephoto lens sometime during the summer of 2018. No other details were revealed, but it should have massive appeal to sport and wildlife photographers.
