Canon XF705

The XF705 joins the XF300 and the XF305 in Canon’s class line up.

Introduction

Canon have always been strong in the field of traditional compact broadcast cameras. The XF705 joins the XF300 and the XF305 in Canon’s class line up.

Features and Design

The XF705 features a 1.0-inch 4K UHD CMOS image sensor and dual DIGIC DV 6 Image Processors (as featured in the EOS C200).  Its 13.4 megapixel native sensor resolution (4,268 × 3,148) offers 4K images with an effective resolution of 8.29 megapixels in UHD format (3,840 x 2,160). The XF705 can record 4K UHD video up to 60p, as well as slow motion recording up to 120fps in Full HD. The XF705 is also the first Canon camcorder to adopt the H.265/HEVC codec, which improves the efficiency of 4K data handling. 

For shooting in a range of situations the XF705 features a built-in 0.46-inch electronic viewfinder and an adjustable 4.0-inch touch panel LCD monitor. The vari-angle screen makes it easy for viewing in multiple positions. The XF705 camcorder's touch panel LCD excels when it comes to supporting Dual Pixel CMOS AF. The autofocus control is enabled simply by tapping a finger on the part of the screen the user wants in focus. Users can also use the touch panel to move the autofocus target manually. The monitor includes Peaking, Marker and Zebra displays.

External audio recording is covered by two XLR terminals with independent audio level control and a 12G-SDI output.

Canon have created a new removable shoulder pad and adjusted the position of the hand grip to give it a more comfortable postion. New also it a broadcast style zoom rocker which allows for bettter filming stability.

XF705 features an Infrared Mode (green/white selectable) allowing the capture of video in conditions with little to no ambient light. It’s unusual to find such a high end feature in a camera in this class.

The buttons and controls of the camera are easy to operate and positioned, look tidy and are well labelled.

Remote control of the camera is possible both wirelessly through a smartphone or tablet with Browser Remote, or the optional Canon RC-V100 wired remote controller.

The XF705 weighs about 2.6 kg (5.7 lb) and is compact making it especially useful for news gathering and documentary productions.

Usability

Two SD card slots are built in which 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. Using a 64GB SDXC card recording in XF HEVC (160 Mbit/s) about 50 minutes per card is possible with an additional card in relay mode provides up to 100 minutes of storage.

The fixed 15x zoom lens offers a very wide focal length range of 25.5mm - 382.5mm (based on 35mm) and a minimum aperture of f/2.8 to f/4.5. It maintains 4K UHD quality throughout the entire zoom range, while the camcorder's Dual Pixel CMOS AF helps drive fast and accurate autofocus.

If a FullHD image resolution is sufficient, the maximum focal length can be doubled to 765mm using the Advanced Zoom mode. Since this is a digital zoom with a smaller sensor area zoomed up, this is only possible via a sensor crop, i.e. with reduced resolution and higher noise.
 
The image can be darkened via the usual steps ¼, 1/16, 1/64 via an ND filter wheel It’s a pity that the Vario-ND filter system introduced by Sony is not in use in the camera.

The Dual Pixel CMOS Autofocus (DPAF) works very well even in difficult lighting conditions and low contrast. Alternatively, a focusing aid can also be used for manual sharpening. Touch focus control, face recognition and object tracking are also included.

Colour profiles include Hybrid Log Gamma (HLG) and HDR. Via a 12G SDI and HDMI 2.0 output, it is possible to record both separately in SDR (with LUT) and uncompressed on an external recorder. Canon Log3 can also be used.

Finally, the XF705 features WiFi functionality allows proxy files to be sent via an FTP server even if they are stored on an SD card.
