SONY ALPHA 1 (A1) BODY Professional4 months ago - Electronics & Appliances - Montréal - 17 views
The Sony Alpha 1 is the one camera designed to do it all. Built without compromise, this full-frame mirrorless offers high-resolution for stills shooting, impressive 8K video recording, speed and sensitivity, and connectivity for the most demanding professional workflows. Pairing the efficient stacked sensor design with optimized processing means the a1 is capable of 30 fps continuous shooting at full-resolution, 8K 30p, and 4K 120p 10-bit video recording, and still offers versatile sensitivity up to ISO 102400 for low-light shooting. The sensor's design also includes a 759-point Fast Hybrid AF system, which offers advanced subject tracking and Real-time Eye AF on humans and animals, even including a dedicated Bird Mode.
The camera's shutter design has also been revised and now offers full-frame flash sync speeds up to 1/400 sec, and flash sync up to 1/200 sec is even supported when working with the silent electronic shutter. At the rear of the camera is a 3.0" tilting touchscreen LCD and both Bluetooth and Wi-Fi connectivity, with 2x2 MIMO support, offer wireless remote control and file transfer capabilities. The sensor also enables recording lossless compressed raw files for flexible editing during post-production while maintaining a relatively lightweight file size. Suiting fast-paced continuous shooting is a blackout-free viewfinder experience, which makes use of a 240 fps refresh rate for fluent eye-level viewing.
Making use of the high-resolution sensor and fast processing capabilities, UHD 8K 30p XAVC HS 10-bit 4:2:0 video recording is possible using the full width of the sensor, offering 8.6K oversampling for impressive sharpness and realism. The a1 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.
Affording extensive customizable color and gamma controls, you can adjust the gamma, black level, knee, color level, and more. Also, users can use the same S-Log2 Gamma Curve that is found on high-end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal than traditional REC709, for increased post-production flexibility. Fast sensor readout and improved processing also enable up to 120 AF and AE calculations to be performed per second for faster, more responsive tracking and accurate results. Helping to fine-tune how the focusing system performs, seven-step AF transition speed and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur.
