تفاصيل المنتج
An ideal starter bundle, the Sony Alpha a7R IV Mirrorless Digital Camera with 24-105mm Lens Kit from B&H pairs the high-resolution full-frame camera with the FE 24-105mm f/4 G OSS standard zoom lens.
Moving to an even higher resolution realm, the Sony Alpha a7R IV continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP Exmor R BSI CMOS sensor and enhanced BIONZ X image processor, which afford impressive imaging results with marked smoothness, a 15-stop dynamic range, and, of course, speed. Up to 10 fps shooting is possible along with the ability to record UHD 4K30 video, both with support for Real-time Eye AF and Tracking AF technologies. The revised sensor design uses a Fast Hybrid AF System, with 567 phase-detection autofocus points, for notably fast and accurate focusing performance. Despite being such a high-resolution sensor, it is also distinguished by its flexible native sensitivity range from ISO 100-32000 for working in a variety of lighting conditions. Additionally, benefitting both stills and video operation, the a7R IV retains the 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is effective to minimize the appearance of camera shake by up to 5.5 stops.
Balancing the imaging merits, the a7R IV also sees an updated physical design with more robust weather sealing to suit working in especially harsh weather conditions. In terms of usability, the OLED electronic viewfinder has been boosted to an impressive 5.76m-dot resolution for clear viewing and the 3.0" rear tilting touchscreen LCD has a high 1.44m-dot resolution for crisp playback, live view shooting, and menu navigation. Dual SD card slots are both UHS-II-rated for faster performance and the inclusion of a USB Type-C port permits tethering and quick in-camera battery charging. Additionally, built-in Bluetooth and both 2.4 and 5 GHz Wi-Fi bands afford wireless transferring and remote camera control from linked mobile devices.
Dedicated Accessories from Sony
For improved audio recording, and making use of the a7R IV's updated Multi Interface Shoe and digital audio interface, there is the ECM-B1M Shotgun Microphone, which delivers a digital audio stream directly to the camera for cleaner quality with low noise. For even more advanced audio control, there is also the XLR-K3M XLR Adapter Kit, which is a dual-channel digital XLR audio adapter for connecting external microphones to the camera while still benefitting from the digital audio interface.
61MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 68 consecutive frames, with full-time AF/AE.
Fast Hybrid AF System
The apt focus system also lends itself to a variety of focusing functions for refined accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expand Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. Additionally, 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. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details. The 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.
5-Axis SteadyShot INSIDE Image Stabilization
For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
Pixel Shift Multi Shooting
UHD 4K Video Recording in XAVC S Format
4K video recording also avails the ability to produce 8MP stills during playback by taking a frame grab from a movie and storing it as a separate file.
