Image Processing Engine
A proprietary image processor, the DIS-2A, handles data from the sensor. The processor supports simultaneous real‑time noise reduction, color interpolation, and dynamic range compression. Image outputs are available in RAW (DIS-RAW) and JPEG formats, with JPEG processing options including multiple color profiles, sharpness levels, and custom noise reduction curves. The processor also manages video compression, enabling 4K recording at 30 fps and Full‑HD recording at up to 120 fps.
Autofocus and Metering
Autofocus System
The DSLRA290L employs a 9‑point phase‑detection autofocus system, with the central point being cross‑type for improved focusing accuracy. The remaining eight points are located along a horizontal line, allowing for flexible subject tracking. The autofocus system is compatible with both the camera’s native lenses and third‑party lenses that support Phase‑Detection AF (PDAF). A continuous AF mode is available for moving subjects, with focus tracking sensitivity adjustable via firmware settings.
Metering Modes
Metering is handled by a 64‑segment matrix system that evaluates exposure across the frame. Three selectable metering modes are provided: Multi‑zone, Center‑weighted, and Spot. Each mode calculates exposure based on the sensor’s light intensity distribution, allowing photographers to adapt to varying lighting conditions. The camera also features an exposure simulation display on the LCD to preview exposure settings before capture.
Video Capabilities
Resolution and Frame Rates
The DSLRA290L supports 4K UHD video recording at 30 fps and 30 fps progressive mode. Full‑HD (1920×1080) recording is available at up to 120 fps, enabling smooth slow‑motion footage. The camera also records Full‑HD at 60 fps with a 10‑bit internal color depth, preserving more tonal detail for color grading.
Audio and Accessories
Audio input is facilitated through a 3.5 mm jack, allowing connection to external microphones. The camera’s built‑in stereo microphone provides high‑quality ambient audio capture. A dedicated headphone jack supports real‑time monitoring of audio during recording. For advanced users, the DSLRA290L offers a time‑code output via a 4‑pin DIN connector, facilitating synchronization with external video equipment.
Connectivity and Interface
Wireless Transfer
Wi‑Fi connectivity operates on the 2.4 GHz band and supports IEEE 802.11b/g.
