    15x Optical 4K UHD Zoom Lens with 5-Axis Optical Image Stabilization
    The XF705 Professional Camcorder incorporates a Canon 4K video lens that leverages proprietary Canon optical technologies derived from years of experience in developing Cinema, Broadcast and EF-series lenses.


    Inspired by the same high level of optical precision used in Canon broadcast and photographic lenses, the Canon XF705 camcorder incorporates a Genuine Canon 15x optical zoom lens that maintains 4K UHD quality throughout the entire zoom range, and offers a focal length range of 25.5 to 382.5mm (35mm film equivalent). Users can get up to 30x Advanced Zoom when shooting in Full HD, which utilizes the XF705 camcorder’s full 4K UHD sensor to extend the zoom range while maintaining image quality.



    5-Axis Optical Image Stabilization
    The XF705 camcorder also incorporates a 5-axis Optical Image Stabilization (IS) system, featuring three modes of image stabilization: Standard, Dynamic and Powered. In Standard IS mode, the stabilizing angle is made constant, independent of the zoom magnification. Dynamic IS mode extends the stabilizing range at the wide end of the focal length, allowing for image stabilization when shooting while walking. Powered IS mode helps facilitate stabilization in the low frequency range at the tele end, and should be used exclusively for fixed-point shooting which does not involve panning.



    Optional Wide and Tele Accessories
    The optional Wide Attachment WA-U58 and the Tele Converter TL-U58 accessories expand the creative capabilities of the XF705 camcorder.


    The Wide Attachment WA-U58 offers a 0.8x wider angle of view that enables users to capture more of a scene, especially when indoors or in tight spaces, to lend better perspective to your video narrative. The Tele Converter TL-U58 provides extended 1.5x longer telephoto range for the XF705 camcorder’s fixed lens, allowing distant subjects to be captured with brilliant clarity.



    Dual DIGIC DV 6 Image Processors
    The XF705 Professional Camcorder incorporates Canon’s dual DIGIC DV 6 Image Processors, which are integral in providing high image quality, advanced performance and convenient operability. This advanced core technology component provides the image-processing power and speed that enables features such as 4K UHD video acquisition, image stabilization, slow and fast motion recording and precise Dual Pixel CMOS AF.




    4K UHD 59.94P 4:2:2 10-bit Recording
    The XF705 Professional Camcorder supports 4K UHD 59.94p 4:2:2 10-bit recording to support natural and realistic 4K video production.


    H.265/HEVC
    The XF705 Professional Camcorder is the first Canon video camera that can record in H.265/HEVC, which offers a compression ratio of about 2x the mainstream coding technology of H.264/AVC- improving the efficiency of 4K data handling. By using XF-HEVC, which combines 4K UHD image quality with an extremely efficient compression standard, the XF705 can record many hours of content on versatile SD cards.



    Internal Recording of Two HDR Formats
    The XF705 Professional Camcorder records in the two most commonly used HDR formats, Hybrid Log Gamma (HLG) and Perceptual Quantization (PQ), which help ensure full color rendition and wide latitude with a much greater range from black to pure white.
    HLG is best suited to live broadcast and live streaming events due to its internal gamma curve compatibility with conventional TVs, which helps to better handle relative luminance values. PQ is used for the color grading and mastering of content. This is a relatively new gamma curve based on human vision characteristics that handles luminance values of up to 10,000 cd/m2 with absolute luminance.


    Dual SD Card Slots
    Dual SD card slots allow for simultaneous or relay recording. Simultaneous recording allows you to record on both SD cards at the same time, so that you can use one as a backup. Relay recording allows uninterrupted recording from one card to the other when the first memory card becomes full.




    Slow and Fast Motion Recording up to 120fps
    The XF705 Professional Camcorder supports slow and fast motion recording, and can record in a different frame rate from playback for slow and fast motion effects. Slow motion recording of up to 120 fps (x0.2) in Full HD is supported, helping to create an emotionally moving and exciting style of video.




    Dual Pixel CMOS AF Exclusive AF Technology
    The XF705 Professional Camcorder features Dual Pixel CMOS AF, Canon’s exclusively developed high-speed, high-precision autofocus technology. Dual Pixel CMOS AF assists not only with standard shooting, but also with 4K UHD 60p, Full HD 120p and other high-frame rate applications that require crisp frame-by-frame accuracy.



    Dual Pixel CMOS AF
    Each pixel in the camcorder’s CMOS sensor is configured with two photodiodes. Two independent image signals can then be detected at each photosite. By implementing phase-difference AF, smooth focusing is accomplished with much higher speed and accuracy than was possible with previous technologies.

    Dual Pixel CMOS AF with Touch Focus
    The XF705 camcorder’s 4.0-inch touch panel LCD enables smooth, intuitive operation of Dual Pixel CMOS AF. This auto focus technology can be employed when shooting a scene by tapping a finger on the desired area of the scene you want the lens to focus on. Dual Pixel CMOS AF offers continuous AF within a horizontal and vertical range of the screen of approximately 80%. It also provides highly accurate Face Detection AF, which assists during single-operator shooting. Users can also use the touch panel to move the autofocus target manually.

    Face Detection AF
    The Face Detection AF feature has two modes – Face Priority AF and Face Only AF – that offer users flexibility in how they choose their autofocus for a subject or scene.

    HDR Recording with HLG/PQ Shooting Assist
    The XF705 Professional Camcorder supports HDR recording in Hybrid Log Gamma (HLG) and Perceptual Quantization (PQ) formats. This helps ensure full color rendition and wide latitude with a much greater range from black to pure white – ideal for the delivery of live streams, broadcasts and post-production projects.
    The XF705 also features a variety of assist functions to support auto/manual exposure control during HDR shooting, allowing users to record HDR video using their usual shooting methods.

    HDR->SDR Gain
    The XF705 Professional Camcorder includes a helpful feature to allow shooters to adjust exposure levels (gain) during simultaneous HDR and SDR recording. SDR gain difference vs. HDR can be fine-tuned from -7.5dB to +7.5dB.

    When HDR video is shot at proper exposure outdoors, SDR may become too bright, so the brightness level can be adjusted using a negative gain. When HDR video is shot at the proper exposure indoors, SDR images may become too dark, so the brightness can be set to a positive gain.


    Canon Log 3
    Designed with creative post-processing in mind, Canon Log 3 is a gamma designed for simple grading at a deep level for toning up dark areas and adjusting color tone/gradation to make noise less noticeable. By shooting in Canon Log 3, users can manipulate the information that’s recorded, from dark areas to highlights. This makes the range for color grading wider and enables video to be produced with generous latitude that couldn’t be reproduced with video gammas. Simple previews can also be performed on-site with Look-Up Table (LUT) accuracy.
    Canon Log 3 shooting can be especially effective for documentaries and other settings with drastic changes, along with outdoor and other locations where light conditions change frequently, or where monitoring setups may be insufficient


    Wide DR Gamma (800%) Support
    The XF705 Professional Camcorder supports Wide DR Gamma. For natural and realistic-looking image capture that faithfully represents the scene at hand, Wide DR Gamma achieves a wide dynamic range of 800% to produce almost seamless tone gradations, resulting in smooth detail and virtually no blown-out highlights.



    4.0-inch Rotating Touch Panel LCD and 0.46-inch OLED Electronic Viewfinder
    An adjustable 4.0-inch rotating touchscreen LCD monitor and a built-in 0.46-inch OLED electronic viewfinder enhance usability.
    The monitor allows for on-camera monitoring of footage in real time and features a rotating design that brings flexibility and user preference to support 4K shooting, which demands strict focus accuracy. It rotates both left and right to support various shooting scenes, including walls and narrow spaces. The screen can be opened an additional 35°forward from the usual set position to prevent accidental shock or to allow the director to check a scene in the camcorder during shooting.

    The OLED viewfinder displays approx. 1.23 million dots, allowing shooters to see bright parts in the image and dark shadow detail. The EVF can then be used to adjust parameters and camcorder settings accordingly.


    Live IP Streaming
    The XF705 Professional Camcorder offers the ability to stream video live online using IP transmission in either the H.265/HEVC or H.264/AVC encoding format. Live H.265 streams (16M bps at 59.94p) can be used to reliably distribute either 4K UHD or Full HD data efficiently to a variety of TV and social media platforms.
    The livestream can be viewed directly from the camcorder using the on-board LCD monitor, sent to a standalone HEVC IP encoder or redirected to a 4K UHD monitor for a confidence check and public viewing. In addition, Live HDR data (Message/Mastering Display Color Volume) can be added in the H.265 stream if required to help improve picture quality.

    Flexible Audio Inputs with Linear PCM 4-channel Support
    The XF705 Professional Camcorder offers a variety of ways to record high-quality linear PCM 4ch audio: through two XLR terminals, an internal stereo mini-jack mic terminal or from the camcorder’s internal stereo mic. The on-board 4ch audio independent settings let users set recording levels, input sensitivity and limiters for each channel.




    RC-V100 Remote Controller Support
    The XF705 Professional Camcorder is compatible with Canon's optional RC-V100 Remote Controller, enabling image quality adjustments and other important operations to be set from a distance. The RC-V100 plugs into the XF705 through the remote terminal on the rear panel.

    Compact, Lightweight and Ergonomic Design
    The XF705 Professional Camcorder is compact and lightweight, making it especially useful for on-the-go Electronic News Gathering (ENG) and documentary production applications.

    Parece que a nivel de sensor el de 1" es el nuevo 1/3".

    Una cámara batallera, no está nada mal de especificaciones, el problema es el precio (o mejor dicho la competencia)...por 7000€ tienes una Fs7 o una Fs5II con cierto equipamiento ya.
