Serial digital interface (SDI) is a family of video interfaces standardized by SMPTE. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s.
These standards are used for transmission of uncompressed, unencrypted digital video signals Coaxial variants of the specification range in length but are typically less than 300 meters. SDI and HD-SDI are currently only available in professional video equipment.
Three 1/3" CMOS Exmor sensors, a 20x 'G' lens and dual XLR inputs are carried over from the Z5, but the beautiful video and audio these elements produce are now in service to a higher level of professional control. An HD-SDI output makes this one of the most affordable camcorders to provide uncompressed 4:2:2 output, while HDMI and RCA outputs allow for connection to professional and consumer-grade monitors alike. Timecode sync between two or more cameras is also possible, and the addition of GPS technology makes for another first on an AVCHD pro camcorder.
This is the impressive successor to the popular PMW-EX1. While retaining everything that was right about the previous camera, Sony has listened to its professional users and taken several steps forward, not only improving ergonomics and convenience, but bringing a whole new set of features to the world's only full HD compact camcorder.
Like its predecessor, the PMW-EX1R's core is its three 1/2"-type CMOS sensors and 14x Fujinon zoom lens. This heavyweight imaging combo captures full 1920 x 1080 hi-def images to solid state SxS PRO memory cards at multiple bit rates, resolutions and frame rates. Whether you're shooting weddings, documentaries or feature films, there's a frame rate and resolution for you--from 60fps and native 23.98p recording at 720p, to 1fps at 1080i.
But along with its already proven imaging abilities and professional workflow, the PMW-EX1R expands its usability by offering DVCAM SD recording, XDCAM HD compatibility, and HDMI output. That means no more time-consuming downconverting or transcoding to work in different formats or with different recording and playback devices. Other new features add even more convenience and flexibility, including a high-resolution 1.23MP viewfinder, Cache Record, one-click S&Q button, auto iris, and even image inversion for flipping the image while shooting with a 35mm adapter. Make no mistake: the Sony PMW-EX1R is the first HD compact camcorder that truly does have it all.
The PMW-EX1R camcorder comes equipped with a wide range of interfaces optimized for a variety of operational needs. These include an HD-SDI output, downconverted SD-SDI output, i.LINK (HDV/DV) input/output, USB2 and analog composite/component output.
