Alpha a7 III Body + FE 100-400mm f/4.5-5.6 GM OSS Lens
24MP Full Frame Mirrorless Format Camera Kit
The Alpha a7 III from Sony is a Mirrorless Digital Camera that is suited for both photo and video in a variety of working situations. The full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X Image processor pair to offer an impressive 10 fps continuous shooting rate. Refined for improved speed, low-light performance and autofocus performance for faster, more reliable subject tracking along with wide frame coverage.
An updated Fast Hybrid AF System employs a combination of 693 phase detection points and 425 contrast detection areas for quicker focus on subjects in testing lighting conditions. There have been further processor improvements with reduced noise - ISO 100-51200, expandible through to ISO 50-204800. Video recording capabilities have also improved significantly when recording UHD 4K video, utilising the full width of the full frame sensor.
Additionally, benefitting both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5 stops. The a7 III's body design has also been developed to include a rear 3.0", 922k dot touchscreen tilt LCD. A 2.36m-dot Tru-Finder OLED EVF is also added for bright and clear eye-level monitoring. For greater shooting flexibility, dual SD memory card slots are now featured, and a larger NP-FZ100 battery is also employed to achieve up to approximately 710 shots per charge.
The magnesium-alloy chassis and weather-sealing also render the a7 III dust and moisture resistant. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 177 consecutive frames, and with full-time AF/AE when working with either a mechanical shutter or an electronic shutter. If shooting in live view mode, a continuous shooting rate of up to 8 fps is also possible.
Here the a7 III is kitted with the FE 100-400mm f/4.5-5.6 GM OSS lens from Sony, a telephoto lens for full-frame E-mount cameras, ideal for sports, wildlife and action photographers. It is also compatible with APS-C models where it will provide a 150-600mm equivalent focal length range. As part of Sony's G Master series, it is designed to achieve high resolution and sharpness by targeting and correcting a variety of spherical and chromatic aberrations.
The optical design uses one Super ED and two ED elements for increased clarity and colour fidelity, as well as Nano AR Coating to reduce surface reflections, flare, and ghosting. A floating elements system benefits image quality when working at the 98 cm minimum focusing distance with 0.35x magnification. This is complimented by a rounded nine-blade diaphragm to produce attractive out of focus 'bokeh' areas.
A Direct Drive SSM system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control. The lens is also equipped with Optical SteadyShot image stabilisation to minimise the appearance of camera shake for sharper handheld imagery when working with slower shutter speeds. This stabilisation system can also be combined with select camera's sensor-shift type image stabilisation for more effective control of camera blur.
The lens is completed with a robust and intuitive physical design that includes a zoom torque adjustment ring that lets users dial in the stiffness of the zoom mechanism, and a focus range limiter switch for faster focusing. It also features multiple customisable focus hold buttons, an AF/MF switch, and a removable and rotatable tripod mount. It is finished with a dust- and weather-resistant construction with a fluorine-coated front lens element to help prevent smudges and dust from adhering to the glass surface.
The FE 100-400mm f/4.5-5.6 GM OSS lens is also compatible with Sony's optional 1.4x and 2x FE teleconverters for reaching distances of up to 800mm.
