Sony Alpha A7 IV Mirrorless Digital Camera 특가 악세서리

Sony Alpha A7 IV Mirrorless Digital Camera 기재사항

An all-arounder that pushes beyond basic, the Sony Alpha a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators.

The newly developed 33MP Exmor R CMOS sensor pairs with the BIONZ XR processor from the Alpha 1 to achieve quick shooting up to 10 fps and 4K 60p video recording, along with broad sensitivity up to ISO 51200 and a wide 15+ stop dynamic range. Beyond image quality, the sensor and processor also contribute to an advanced AI-based AF system that supports Real-time Eye AF and Real-time Tracking for intuitive AF control and subject tracking.

This fourth-generation of the a7 camera also sports an updated body design that houses a higher resolution 3.68m-dot EVF, vari-angle touchscreen LCD, and dual memory card slots, including one dual CFexpress Type A/SD UHS-II slot. Connectivity and streaming are also a key attribute of this camera, and it supports a simple plug-and-play design for live streaming directly from the camera when connected to a computer via USB.

Sensor and Processor
33MP Exmor R BSI CMOS Sensor
Newly developed 33MP Exmor R full-frame sensor features a back-illuminated design that promotes high clarity, low noise, and vivid color rendering. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format.

BIONZ XR Processor
Using the flagship-class BIONZ XR engine, high-speed image processing capabilities are available for fast continuous shooting, 4K video recording, and advanced AF tracking performance. The quick processing also helps to reduce rolling shutter and other motion distortions for clean rendering of moving subjects.

In terms of shooting speeds, the sensor and processor enable up to 10 fps shooting, using either the mechanical or electronic shutter and with AF/AE enabled. Also, the buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card.

Advanced External Flash Control
Suiting working with flash while photographing fast-moving subjects, P-TTL flash metering is possible in between each exposure when working with lo, mid, or even hi-speed continuous shooting modes. This helps to maintain stable illumination if making low-light bursts and greatly benefits working in changing light or low-light conditions. The updated flash control system also helps to reduce flash trigger lag, uses the camera's AWB information for natural color rendering, and supports adjusting select flash and transmitter units directly from the camera's interface.

Video Recording
4K 60p Video Recording in 10-Bit
Making full use of the high-resolution 33MP sensor and fast processing capabilities, UHD 4K 30p XAVC HS 10-bit recording is possible using the full width of the sensor, offering 7K oversampling for impressive sharpness and realism.

There is also oversampled 4K recording, via a 4.6K capture area, with a Super 35 crop, that offers UHD 4K output up to 60p in 10-bit.

No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than one hour of continuous 4K 60p 10-bit 4:2:2 recording, for example.

The a7 IV employs a pair of codecs to suit different workflows: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.

S-Cinetone, S-Log3, and Other Color and Gamma Controls
S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 cameras, along with the a1 and a7S III, and is based on technology from the professional Cinema Line cameras, such as the VENICE. This color profile offers natural mid-tones, soft colors, and especially well-controlled highlights.

HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera.

S-Log3 is also available for producing a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

Fast Hybrid AF System
AI-Based Autofocus
Covering approximately 94% of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modes, to benefit both video and stills applications.

Real-time Tracking and Real-time Eye AF
Borrowing from the flagship AF system, the a7 IV has tuned tracking and subject detection capabilities that lock onto subjects quickly and refines focus accurately on recognized eyes and faces of subjects:

Real-time Tracking is an AI-based subject recognition system that recognizes color, pattern, and subject distance information for high accuracy and focusing speed.

Beyond just tracking subjects, Real-time Eye AF fine-tunes the focusing accuracy and recognizes human, animal, and bird's eyes for critical sharpness. Real-time Eye AF even maintains focus on a subject's eye when they leave and re-enter the frame, allowing for working in more spontaneous shooting situations.
