Alpha a7 III + Tamron 17-28mm f/2.8 SP Di III RXD
+ Tamron 28-75mm f/2.8 SP Di III RXD 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 two Tamron lenses - the 17-28mm f/2.8 Di III RXD and 28-75mm f/2.8 Di III RXD. Together, the two lenses offer an ultra wide angle to standard zoom range.
The Tamron 17-28mm f/2.8 Di III RXD lens is a versatile wide-angle zoom lens for full-frame Sony E-mount mirrorless cameras. It can also be used with APS-C models where it will provide a 25.5-42mm equivalent focal length range. Its bright maximum aperture of f/2.8 offers control over depth of field and benefits working in low light conditions, while its ultra-wide to wide focal length range makes it well-suited to shooting landscape, astrophotography and architecture.
The Tamron 28-75mm f/2.8 SP Di III RXD lens for Sony E-mount mirrorless cameras spans wide-angle to portrait length. It can also be used with APS-C models where it will provide a 42-112.5 mm equivalent focal length range. The versatile focal length range is combined with a bright f/2.8 constant maximum aperture to make the lens well-suited to working in difficult lighting situations, and an excellent choice for capturing a variety of subjects.
Benefitting the optical designs in both lenses is an RXD (Rapid eXtra-silent stepping Drive) autofocus motor, which enables quick, near silent autofocus performance to suit stills and video recording, along with full time manual focus override and a minimum focusing distance of 19 cm.
The lenses sport a moisture-resistant construction along with a fluorine coated front element to protect against fingerprints and smudging.
