Overview & Specifications
Sony a7R IIIA Mirrorless Camera Blending Speed and Resolution Proving that speed, resolution, and video capabilities can all coexist, the Sony a7R IIIA is a versatile, high-performance camera characterized by not only its resolution, but by its multimedia versatility.
42.4 MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor Featuring a back-illuminated design, the full-frame 42.4-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed. 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. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 42.4-megapixel stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400. Also, it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full-frame sensor. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture an impressive 15-stop dynamic range at low sensitivity values.
Autofocus and Image StabilizationAn evolved 4D FOCUS system now employs a combination of 399 phase-detection points, which cover approximately 68% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7R models, as well as improved low-light focusing response down to -3 EV.
- Lock-on AF maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject
- Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
- Eye AF can be used to base focus on recognized human subjects eyes for portraits and is available in both AF-S and AF-C modes, for both stills and video. Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills
- Focus Magnifier function can be used for critical focus when homing in on minute subject details
- Rear touchscreen can also be used for Touch Focus control, and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder
- For more personalized control over focus, and benefitting working in either vertical or horizontal shooting orientation, the AF area can be switched in orientation to better suit your subject matter
- AF tracking sensitivity can also be customized in five steps to match how a subject is moving
- Frequently used focus point settings can be memorized and recalled with a custom button for faster switching between focus settings
Sony FE 135mm f/1.8 GM Lens Prized for its ability to isolate focus, the FE 135mm f/1.8 GM from Sony is a medium telephoto prime characterized by its bright and sophisticated design. The f/1.8 maximum aperture excels in low-light conditions and also offers increased control over depth of field for working with selective focus techniques. The advanced optical design incorporates two extra-low dispersion elements, including one Super ED element, to reduce chromatic aberrations and one XA (extreme aspherical) element, which significantly controls spherical aberrations for a high degree of image sharpness and clarity. Additionally, a Nano AR coating has been applied to limit ghosting and lens flare for increased contrast and color fidelity when working in strong lighting conditions.
Complementing the optical assets, this lens is also notable for its inclusion of an 11-blade circular diaphragm to produce smooth, soft-edged bokeh with selective focus imagery. For controlling focus, an XD Linear Motor system is employed that is quick and quiet, and also lends more responsive control for manual focus operation. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions and dedicated focus hold buttons, AF/MF switch, and manual aperture ring lend further control while shooting.
