*As of December 27, 2018

4K UHD 59.94p/50.00p 4:2:2 10-BIT

Perhaps no single camera specification seems to matter more to camera buyers than what kind of recordings the camera is capable of producing, and the XF705 has you covered. The XF705 supports 4K UHD 59.94p/50.00p 4:2:2 10-bit recording to support true-to-life 4K video productions. This is Canon’s first offering that utilizes the XF-HEVC format, and while it will ship with only one 1920x1080 4:2:0 8-bit MPEG4 option, it will include multiple XF-AVC 8-bit options with a future firmware update. Overall, this selection of recording options enables the outstanding image quality befitting a flagship model of the Canon XF Series.

XF705 internal recording options and future firmware updates

SUPPORTS FHD 120P/100P 4:2:2 10-BIT 180Mbps

The XF705 supports slow motion recording of up to 120 fps. The Slow and Fast Motion recording option is only available with the camera set to XF-HEVC at 1920x1080 resolution.

INTERNAL RECORDING OF TWO HDR FORMATS

Answering and delivering on the demands of the industry, the XF705 records internally in two HDR standards, HLG and PQ. Streamlined 4K and HDR workflows will contribute to the proliferation of 4K/HDR content availability.

HYBRID LOG-GAMMA (HLG)

HLG (Hybrid Log Gamma) is an HDR format jointly developed by the BBC and NHK, which is optimized for broadcasts and live streams with compatibility on non-HDR TVs. HLG utilizes a gamma curve compatible with conventional TVs to handle relative luminance values. Peak luminance for HLG is a relative value depending on the receiving display’s performance capabilities.

PERCEPTUAL QUANTIZATION (PQ)

PQ (Perceptual Quantization) is an HDR format developed for accurate mastering by Dolby. It features a gamma curve with tone compression based on human eye characteristics. It is used for a variety of mastering needs; for example, broadcast mastering, online streams and theatre projection. It handles luminance values of up to 10,000 cd/m2 with absolute luminance, meaning that luminance values are mathematically accurate regardless of the display device’s capabilities.

The XF705 Custom Picture menu offers PQ and HLG as gamma options for internal recording.

HLG AND PQ RECORDED INTERNALLY

While HDR production has typically culminated during the postproduction process, HDR video can be recorded internally to SD cards with just a simple selection on the menu. When recording in XF-HEVC (4:2:2 10-bit), simply select ”HLG” or “PQ” using the Custom Picture preset/gamma setting.

Compared to conventional SDR video, this offers a much greater range from black to pure white, making bright subjects brighter and dark subjects darker, and displaying landscapes with greater realism — similar to what’s seen with the human eye.

The Hybrid Log-Gamma curve in the XF705 is compliant with the latest HDR operational guideline ITU-R BT. 2408, so images can be captured that have a high affinity with SDR, allowing the look for HLG to be either traditional SDR, or a more natural HDR look.

HDR -> SDR GAIN

When recording HDR internally, an SDR signal can be output and adjusted independently with proper exposure levels according to your scene. For instance when an exterior HDR scene is shot at proper exposure, the SDR signal may become too bright. You can compensate the output for your SDR by applying negative gain. Conversely, while shooting an HDR interior, the SDR image may appear too dark, and you could adjust for that by applying a positive gain value.

This makes simultaneous recording of HDR and SDR possible by recording HDR internally while outputting SDR to an external recorder. This could also be used for monitoring an HDR recording on an SDR display. During HDR/SDR simultaneous recording or monitoring, you can adjust the SDR gain difference vs. HDR to between -7.5dB and +7.5dB.

FIRST CAMERA IN THE XF SERIES TO SUPPORT CANON LOG 3

Canon Log 3, like Canon Log 2 and Canon Log, is a gamma designed with postprocessing in mind. It offers a dynamic range of 800% — a 13-STOP equivalent — while keeping the dark areas and 18% middle gray characteristics of Canon Log.

Shooting in Log allows you to more effectively handle all the image information that’s recorded, from dark areas to highlights. This makes for a wider color grading range and allows you to take advantage of much wider latitude than shooting with video gammas. For on set monitoring, editing and simple color grading tasks, viewing LUTs supporting Canon Log 3 are provided for each viewing output; the HD-SDI, the HDMI, the EVF and the LCD display.

WIDE DR

The XF705 also includes Wide DR gamma. Wide DR gamma smoothly compresses high brightness areas, enabling smoother gradations while suppressing overexposure, and offering a wide dynamic range of 800%. Unlike the knee function, which performs linear compression of high brightness areas, the Wide DR gamma offers the significant benefit of maintaining continuity. This virtually eliminates the need for post processing, letting you use video data just as it’s shot, or if desired, a light amount of color grading.

HIGH SENSITIVITY/LOW NOISE (IMPROVED S/N RATIO)

The XF705 features a newly developed image engine and CMOS sensor: the core components for visual expression, letting cinematographers take high-quality and richly expressive video in almost any situation. A new process and sensor structure with enhanced focusing (condensing) efficiency enable higher sensitivity and lower noise.

The XF705 uses a large 1.0-inch sensor with 3.2μm pixel pitch. In combination with the Dual DIGIC DV 6 image processors, it further enhances high sensitivity and low noise performance. With sufficient lighting, it improves the S/N ratio by 10dB (compared to the XF305). It offers minimum subject illumination of 1.5 lux (Normal1: BT.709, full auto mode, shutter speed 1/30 sec) to increase the shooting area and allow for expressive imaging capabilities.

FEATURES 4K "L" LENS

The XF705 features this ultra high-performance L lens to offer the image quality and operability expected of a flagship model. The red line on the 4K L lens certifies professional quality. The Canon L Lens Series will appeal to professional users looking for outstanding imaging performance, superb operability, environmental resistance, and durability.

The L Lens designation is awarded only to ultra high-performance lenses that use special optical materials such as synthetic crystal fluorite, Super UD, UD lenses, and wide f/2.8–4.5 aperture, and using 14 groups of 18 elements with two-sided high precision aspheric lenses.

It supports operability and reliability that pros demand, including a grip zoom rocker with 16 speed levels, three independent focus/zoom/iris lens rings, and optical (lens shift) plus electronic stabilization.

ULTRA-WIDE ANGLE, HIGH MAGNIFICATION

Innovations in lens barrel structure have resulted in improved optical performance in the ultra-wide angle 25.5mm and high magnification 15x zoom lens (to 382.5mm). It allows you to cover a wide range of scenes with just a single lens — especially when used with either the optional wide-angle or tele-converter attachments. Plus, using the 4K sensor in Full HD, you can get up to 30x Advanced zoom while still maintaining image quality. The close shooting distance is 10mm at the wide end, 60cm across the entire zoom range.

9-BLADE IRIS

The number of iris blades in the lens has been increased to 9 from the 6 in the previous XF305 model for a beautiful and natural bokeh that appears more circular than its predecessor. Having an odd number of blades diffuses diffracted light and results in softer light beams.

SOFTER LIGHT RAYS WITH DIFFUSED LIGHT

An odd number of blades in a diaphragm have the quality of doubling the number of light rays. This enables it to softly diffuse light when shooting night scenes containing practical lights.

A WIDE RANGE OF ASSIST FUNCTIONS TO SUPPORT HDR SHOOTING

The XF705 features a variety of assist functions to support auto/manual exposure control during HDR shooting. These let users shoot HDR video using their usual methods.

HLG/PQ SHOOTING ASSIST FUNCTIONS

Built-in High Luminance LCD Monitor and EVF with viewing assist LUTs

The built-in high luminance LCD monitors and EVF offer viewing LUTs for SDR or HDR image checks during shooting. In order to gauge an HDR scene with confidence, the viewing assist function lets users check approximated images recorded in HLG and PQ with either the LCD panel or EVF.

The XF705 features a variety of assist functions to support exposure control during HDR shooting that let users shoot HDR video using their usual methods.

For video verification and simple editing, gradation and color gamut can be corrected using a LUT for each output. The target outputs are the SDI and HDMI terminals, viewfinder, and the LCD display. Viewing LUT options include BT.709 and BT.2020. There is no effect on card recording.

AUTO IRIS OPTIMIZED FOR HDR SHOOTING

Auto Exposure Shift allows you to concentrate on shooting while the camera automatically applies exposure controls for your scene. Adjustments to AE Shift can be selected in the menu.

This controls the iris based on spotlight metering or standard metering (metering at the center of the screen), and automatically makes adjustments so that bright areas are not too bright. Auto Exposure Shift adjustment is also possible, which offers a fully automatic exposure mode.

EXPOSURE ASSIST FUNCTIONS

A variety of assist display functions let users adjust exposure looking at the image numerically, including adjusting exposure while checking the detailed luminance signal on the Waveform Monitor, or displaying a zebra pattern.

DUAL PIXEL AF: FAST, STRESS-FREE FOCUSING

Dual Pixel CMOS AF is Canon’s exclusive high-speed, high-precision phase detection autofocus technology. It offers assist for 4K shooting that requires fast, accurate focusing — so you never miss a shot.

Dual Pixel CMOS AF is a breakthrough AF technology that uses a CMOS sensor with a structure that combines imaging and phase-difference AF functions. In addition to continuous AF within a horizontal and vertical range of the screen of approximately 80%, the XF705 provides a highly accurate face detection AF, which assists during single-operator shooting. Users can also use both the touch panel and the cross keys to move within the distance measuring area for AF shooting with an adaptable framework.

TOUCH AF & FACE DETECTION AF

The XF705 touch panel enables smooth, intuitive operation of Dual Pixel CMOS AF. And when used in combination with the face detection AF, which can be used in different ways according to the shot, users can just choose the right autofocus method they need.

SUPPORT FOR SWITCHING TO DUAL PIXEL FOCUS GUIDE

The innovative UI applies Dual Pixel CMOS AF phase-difference detection AF technology to graphically notify you if the focus position is in front or behind the subject. This Focus Guide makes manual focusing easier and more reliable — especially when shooting in 4K, which requires strict focus accuracy.

Select the focusing method that best suits your subject or your style. Touch panel + independent focus rings make focusing smoother and more intuitive. Just touch the subject and rotate the focus ring while looking at the guide for smooth and efficient focusing. Use in combination with the Push AF button for free focus control that combines manual and auto focus. Stay old school and go fully manual if you like.

THE SPECS DEMANDED OF A TOP-LEVEL CAMERA IN A COMPACT, LIGHTWEIGHT BODY

The concept retains the basic design of the XF305

ELASTOMERIC SHOULDER PAD OFFERS FOUR-POINT SUPPORT

ELASTOMERIC SHOULD PAD ENABLES SHOULDER PLACEMENT STYLE

The new shoulder pad offers a more stable hold and less user fatigue even after hours of shooting. The camera can be firmly fixed at four points – left hand, right hand,temple, and shoulder – to reduce shake. The shoulder pad can also be removed, if desired.

OPTIMIZED LCD PANEL POSITION

The LCD panel is arranged in the optimum position for use during shoulder-mounted operation. The screen can be viewed at almost the exact same distance as the XF305, meaning users can smoothly transition to the XF705 without missing a beat.

GRIP & HOLD

The tilt angle and hold on the grip has been revised to ease the burden on pro users. A zoom rocker for broadcast equipment has also been added to ensure both a stable grip and reliable operability.

GRIP ANGLED TO BE EASY ON THE WRIST

The grip angle is set at 15° for less wrist strain. This enables a more natural style of shooting that reduces fatigue even after long hours.

ZOOM ROCKER FOR BROADCAST EQUIPMENT

The XF705 features the zoom rocker found on the Canon BT M4 lens and the SG-1. Both width and length have been upgraded from the XF305 to enable stress-free operation.

INDEPENDENT CONTROL OF FOCUS/ZOOM/IRIS

The XF705 features three independent lens rings for focus, zoom and iris to answer the precise imaging needs of pros. The wide independent rings offer direct control over zoom, focus, and iris without having to move a switch. Each has a unique width and feel for intuitive control with your eye on the finder.

ZOOM CONTROL WITH STOPS

The zoom ring features a mechanical zoom stop with a 90° rotation angle from wide to tele ends. This assists with zooming for smoother composition.

CUSTOMIZABLE ZOOM SPEED SUPPORTS HIGH-SPEED ZOOM

Users can arbitrarily set zoom speeds (16 speeds) for each push angle (5 divisions) of the zoom rocker. It also supports high-speed zooming, enabling fast zooms from the wide to tele ends in as fast as one second. Low-speed fixed zoom and high-speed angle of view adjustment can be operated easily with the zoom rocker.

4.0-INCH ROTATING MONITOR

The popular large-screen rotating monitor from the XF305 that can flexibly adapt to shooting circumstances has been carried over to the XF705. With a larger and more detailed screen, it also offers touch panel for improved operability.

FLEXIBLE ROTATION ANGLE

Touch panel-equipped 4.0-inch approx. 1.23M dot LCD monitor

A large, high-resolution LCD has been adopted to support 4K shooting, which demands strict focus accuracy. It rotates both left and right to support any shooting scene, including walls and narrow spaces. The inclusion of a touch panel dramatically improves operability.

The screen can be opened an additional 35° forward from the usual set position.

INDEPENDENT 3-DENSITY ND FILTER

The internal ND filter uses a turret (circular) mechanism that allows the user to select from three densities: ND 1/4, ND 1/16, ND 1/64, and OFF. The ND filter can be used from the open F value, allowing for a wide range of shooting options utilizing the 1.0-inch sensor for soft backgrounds and bokeh effects. Density can be adjusted using the dedicated external buttons. Internal placement of the ND filter allows it to flexibly adjust to various changes in lighting environments, both outdoors and indoors.

DEPENDABLE IMAGE STABILIZATION

The XF705 uses an optical system (lens shift) plus electronic stabilization.

Shake correction can be selected from four control modes through combinations of standard mode, dynamic mode, and powered IS on/off. Powered IS mode ensures stabilization even down to the shaking in the low frequency range at the tele end on the lens. Standard mode relies on optical image stabilization only, prioritizing image quality, while Dynamic mode compensates for vibration while walking. When the setting IS Off, the shift lens is fixed at the center and no stabilization is provided. This enables a more effective control for every type of shot.

ASSIGNABLE BUTTONS

The XF705 features assignable buttons — 14 in Camera Mode, 8 in Playback Mode. Users can very quickly set the functions (over 75 different functions in all) they need to a preferred button location.

SUPPORTS REMOTE OPERATIONS

REMOTE A and REMOTE B (RS422) terminals are built-in. A multi-functional remote controller (the optional Canon RC-V100) is supported for enabling image quality adjustments and other important operations to be set from a distance, like when the cameras mounted on a crane, jib, or other remote operations.

WIRELESS FOCUSING SUPPORTED

Browser Remote, which enables remote camera operation from a tablet, smartphone or other device, also supports focusing. This makes accurate autofocus possible even in situations where manual focusing is difficult, such as when the camera is mounted on a car, crane, gimbal or drone.

NOTE: Actual product and UI may vary

This amazing wireless system lets you perform most shooting operations and settings from a tablet using a simple browser window. It includes being able to adjust the focus area using touch. This method allows you to set accurate focusing adjustments even from remote locations where manual focusing is impossible.

EFFICIENT WORKFLOWS

The XF705 uses H.265/HEVC, which offers a compression ratio of about 2x the mainstream encoding technology H.264/AVC. It is the first Canon video camera to adopt XF-HEVC, the new video format in the MXF container. This vastly improves the efficiency of 4K data handling.

4K HDR CAN BE RECORDED TO AN SD CARD

By using XF-HEVC, which combines 4K UHD image quality with high compression, the XF705 can record many hours on a versatile SD card. This enables better handling of data for a wide range of video production needs.

ABOUT 2X THE COMPRESSION RATE OF H.264

H.265/HEVC offers about 4 times the encoding efficiency of MPEG-2, letting users compress 4K video data to the same size as current BS digital broadcasts. This makes it a next-gen standard format expected to play a key role in both TV broadcasts and smartphone video streaming services.

RECORDS 4K UHD 59.94p/50.00p 4:2:2 10-BIT INTERNALLY

The XF705 offers internal recording on a versatile SD card. Two card slots allow settings for backup, relay recording, and a variety of other recording methods. This will surely streamline workflows and assist with archiving.

OUTPUTS ENABLE DIFFERENT RESOLUTIONS AND FORMATS OVER SDI/HDMI

Simultaneous recording of 4K/2KxHDR/SDR is enabled using an external recorder. Two kinds of recording methods, XF-HEVC 4:2:2 10-bit and XF-AVC 4:2:0 8-bit can be selected, making the overall workflow more efficient by tailoring the deliverables to your specifications.

RECORDING AND OUTPUT COMBINATION LIST

HDR "SIMPLE WORKFLOW WITHOUT COLOR GRADING"

The XF705’s support for high-compression HEVC enables HLG/PQ recording on an SD card. This makes it possible to quickly produce a ‘simple workflow without color grading’ for broadcasts, and also the televising of high-quality HDR video with simple shot editing.
