The Canon XC15 4K UHD Video Camcorder just announced is an upgrade for the XC10 that was released in April 2015. Both cameras are designed to be lightweight, compact optional cameras for the professional user. Ideal for the videographer or as a 'B' camera to complement the more advanced EOS Cxxx range of professional video cameras. Being small and lightweight allows the camera to be used in confined areas or when having to travel light.
So what has changed. Physically we can see from the images that there has been significant re-profiling of the left side and top of the camera. On the left side, the sockets are all now flush with the body, the top has been extended to cater for a new proprietary Audio connector. The Hot shoe on the original XC10 has been replaced with a larger cold shoe. These are there to accommodate the supplied MA-400 microphone adapter first seen with the new C300 Mk II Camera. This adaptor allows for the connection of professional external XLR Microphones for improved sound recording with less noise. The camera base has also had some profile changes.
From a video point-of-view it has the same high-quality recording but now adds a selection of visual expression "Look" modes. These including modes that allow the images to match the look of other Canon professional cameras. Added to the new XC15 is an on-screen waveform monitor. This shows the real-time waveform inset on the LCD monitor and allows for easier exposure monitoring.
Prices are yet to be confirmed but could be considerably more than the XC10.
