Genuine Canon 20x HD Video Lens
The VIXIA HF G40 has a Genuine Canon 20x HD video lens that uses aspherical lens technology to achieve low chromatic aberration and high resolution, while maintaining a compact form factor. Super spectra coating technology lowers flare and ghosting as well.
8-Blade Circular Aperture and Hybrid Focusing System
The Canon 20x HD Video Lens also features an 8-blade circular aperture that reduces the "starburst" effect found in camcorders with non-circular apertures. The result is a more appealing circularly blurred background in the out-of-focus areas. This feature is bolstered by a manual focus ring, which allows more accurate control. For extra flexibility, the manual focus ring can be set to control zoom instead. Besides manual focusing, the camera supports a Hybrid AF with Instant AF or Medium AF, Normal AF, Face Priority AF, and Face-Only AF.
Manual Control
Custom Key and Dial
A Custom Key and Dial feature allows you to assign functions to an easily accessible key and adjust the settings with a control dial. The functions include:
	
Tv/Av: Use the dial to adjust shutter speed (Tv mode) or aperture (Av mode), as needed. In this mode, the key has no effect.
	
Manual exposure: When manual control is selected, the dial can adjust aperture and shutter.
	
Exposure Lock can be set on or off, as can the AGC Limit.
Gain Control
Gain may be manually set from 0 to 24 dB in 1 dB increments. Auto Gain Control Limit allows you to set the maximum gain limit for the image sensor's sensitivity so that image quality can be maximized in low-light situations.
Power Zoom
Power zoom is available in variable and constant settings in three modes: Fast (approx. 1.9-60 seconds), Normal (approx. 2.5-180 seconds) and Slow (approx. 4.0-285 seconds). 16-predefined steps in Constant mode provides added control.
Focus Assist and High-Definition Peaking
The VIXIA HF G40 camcorder provides Focus Assist, which provides 2x magnification of your subject, and deactivates as soon as you start recording. Color peaking highlights the sharpest areas in the frame so you can easily check your focus.
Recording
AVCHD and MP4 Recording Formats
The VIXIA HF G40 supports MP4 recording at up to HD 1080p60 resolution.
Slow and Fast Motion Recording
The VIXIA HF G40 allows you to add a fast or slow motion effect to your captured video by letting you record in a different frame rate than the one you use for playback. You can record interval video from 0.4x to 1200x speed.
Built-In Dual-Band Wi-Fi
Built-in Wi-Fi technology lets you share your HD video through compatible networks, wireless hotspots, and iOS mobile devices using the free Canon Movie Uploader app. Transfer files to selected FTP servers for backup or when a quick transfer is necessary. Share videos over the internet with Canon's free iMAGE GATEWAY online photo storage service as well. You can even watch videos stored on the camera's memory cards directly on your TV, or use your PC or mobile device to browse remotely through the previously recorded videos stored on your camcorder, without connecting a cable.
