Sony : دوربین دیجیتال بدون آینه آلفا A9

A9 liberates you from the limits of conventional SLRs that rely on mechanical systems. The first to use high-speed stacked design, its 24.2-megapixel full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed4. The combination of the CMOS sensor and the enhanced BIONZ X image-processing engine brings you true digital freedom. Ground-breaking, full-frame Exmor RS CMOS sensor and BIONZ X processor team up for 20fps continuous shooting with AF/AE tracking. Stunning high-speed performance and ample buffer let you capture the decisive moment. Non-mechanical electronic shutter eliminates blackout with typical SLR mirror action. An uninterrupted view of the subject is available even during shutter release, with 60fps live-view capability and minimal display lag in continuous shooting. Light directly reaches the image sensor without mechanical interruption. An ingenious fusion of mirrorless construction and new speed-enhancing technologies provides AF/AE at full-frame focal plane. Electronic shutter speeds up to 1/32000 seconds far surpass mechanical shutters for a new imaging expression. You can also maintain shallow depth of field without an ND filter, even under bright conditions. An anti-distortion9 electronic shutter allows silent shooting without mechanical mirror and shutter noise. It's ideal for sports and subjects that demand quiet operation, greatly expanding camera versatility. Real-time Tracking and Real-time Eye AF are both designed for fast, precise and intelligent tracking of your subject, using AI-based algorithms and processing an enormous amount of data in real time. Once you've specified the subject to be tracked, precise focus is maintained while the shutter button is half-pressed. Changes in position are accurately tracked, providing framing flexibility and allowing you to concentrate on getting the best shot. High sensitivity, a back-illuminated configuration, gapless on-chip lens architecture and other Sony innovations deliver stunning images in a wide range of photographic situations. Standard ISO range is ISO 100-51200, expandable to ISO 50-204800. Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times20 the amount of data required for 4K (the equivalent of the amount of data required for 6K) into 3840 x 2160 4K output. This oversampling process plus full-frame pixel readout without binning results in the highest possible 4K movie image quality.
