Features
Canon HD CMOS Pro Image Sensor
Incorporating a proven technology in Canon’s professional level camcorders, HD CMOS Pro is a 1/3” native 1920x1080 image sensor which delivers outstanding video resolution, superb low-light performance and a wide dynamic range. Unlike image sensors found in competitive consumer camcorders, HD CMOS Pro uses fewer pixels, which are significantly larger (61%)* and more sensitive, resulting in optimized video performance.
Outstanding Video Resolution (800 Vertical and 900 Horizontal TV Lines)
Since the effective number of pixels of HD CMOS Pro is equal to 1920 x 1080, resizing is eliminated, allowing Full HD video to be captured and recorded with professional precision.
Superb Low-Light Performance (1.5 lux)**
Because each individual pixel is larger and more sensitive, each is capable of capturing more light, allowing high quality video to be achieved even in dimly lit conditions. The sensitivity of HD CMOS Pro is approximately 25% better than the Full HD CMOS sensor in the 2010 VIXIA HF S-series.

Wide Dynamic Range
A larger pixel area also allows more light to be stored, resulting in 280% improvement in dynamic range for exceptional reproduction of both highlights and shadows.*** Skin tones are captured in a finer gradation, and stable gamma and Auto Exposure control are also achieved resulting in a more ‘lifelike’ image.
* This is compared to the pixel size of Canon’s 2010 VIXIA camcorders of 1.7µm. The current HD CMOS Pro pixel size is now 2.75 µm, reflecting a 61.76% increase in size.
** Rating measured with auto shutter speed of 1/30 second.
*** This statistic is the result of comparisons with Canon’s HD CMOS Pro, versus Canon’s 2010 VIXIA HF S-series camcorders.

Short learning curve, great HD performance
We make short video productions and needed a compact portable easy to use 1080p camcorder. The HF M400 delivered what we needed, true 1080p 16:9 aspect video having very impressive quality. The HF M400 is packed with features, yet has a short learning curve and easy to use controls. We were able to make quality full featured video clips after only a few hours practice. The internal microphone gave good quality audio in face-to-face interviews. When mounted on a tripod the 10x optical zoom gave smooth pan and zoom effects. For hand held shots, optical image stabilization gave great results. If you like to get technical, the HF M400 is packed with features described in a 200+ page manual. We are very impressed with this camcorder after two months heavy use. If you need true 1080p 16:9 AVCHD high definition video capability, the HF M400 delivers. No tape, no hard disc is a plus. All video goes onto two SD cards. Easy to switch out. Many more useful features on this cam. Excellent quality for price.
