- 24.3MP Exmor APS HD CMOS Sensor and BIONZ X Image Processor
- The 24.3MP APS-C-sized Exmor APS HD CMOS sensor and BIONZ X image processor work together to produce high resolution, well-detailed imagery with minimal noise and notable low-light quality and sensitivity to ISO 25600. The sensor utilizes a gapless on-chip lens design, which fills the gaps between neighboring pixels with optimized lenses that match the angle of incidence to increase light gathering ability and produce edge-to-edge sharpness and quality. The processor also contributes to providing a wealth of speed throughout the camera system, including Fast Hybrid AF, a top continuous shooting rate of 6 fps, and full HD video recording in multiple frame rates and formats.
- Fast Hybrid AF System
- The Fast Hybrid AF system utilizes both a 179-point phase-detection system and 25-point contrast-detection system to achieve precise focus in as little as 0.07 sec. Utilizing a Spatial Object Detection algorithm, this fast focusing system first employs the phase-detection AF points to quickly bring the subject into focus and then uses the contrast-detection AF points, with wide AF coverage, to fine-tune the sharpness for ensured accuracy. Beyond supporting single shot modes, this system also provides AF tracking when shooting up to 6 fps in continuous high mode and functions seamlessly when recording full HD movies. This hybrid focusing mode is further accentuated by the incorporation of a touchscreen LCD, which avails touch-to-focus control for critical accuracy in both still and video recording.
For further refinement, a series of distinct AF modes can be selected from depending on the subject. Eye AF is a detail-oriented focusing function that can prioritize a subject's pupil and dedicate focusing performance on that for sharply-rendered portraits; Lock-on AF is a dedicated focusing method for use with moving subjects and adjusts the target frame size as the subject moves throughout the image frame; AF area settings allow you to prioritize specific regions within the frame for increased accuracy; and AF-A (Automatic AF), AF-S (Single-shot AF), AF-C (Continuous AF), DMF (Direct Manual Focus), and Manual Focus modes can also be chosen.
- Full HD Video Recording
- Full HD 1080p video recording is supported at 60, 30, and 24 fps in the high-quality 50 Mbps XAVC S codec. Other recording options include the ability to utilize the AVCHD and MP4 codecs, with support for recording up to 1080p60 video at 28 Mbps. Dual video recording is supported, as well, with the ability to select either XAVC S or AVCHD codecs plus a duplicate MP4 file to be recorded at the same time for greater efficiency when sharing videos online. Additionally, using the integrated HDMI type D output, both 1080i60 and 1080p60 uncompressed 8-bit 4:2:2 video can be recorded to an optional external recorder.
Complementing the video capabilities of the a5100, a built-in stereo microphone is incorporated into the design and records audio in the Linear PCM 2-channel format for XAVC S movies, the AC-3 Dolby Digital format for AVCHD movies, and the MPEG-4 AAC-LC format for web-quality MP4 videos.
Manual focus peaking and a zebra function are also available, to benefit working in manual focus and to assure highlight detail is retained, respectively. A marker setting can be shown on the rear LCD as well, in order to display a center marker, guide frame, aspect marker, safety zone, and other pertinent features for video recording.
