A head scratcher coming shortly? A camera which no-one expects? Where's HarryFilm? - I would have expected some ideas by the 4th page of comments!
It's an APS-C sensor with 24 megapixels stills R-style mount in an XC-15 Style body (i.e. a nice side-grip!) with 120 fps 1080p video, 60 fps DCI 4K video with Interframe 10-bit 4:2:2 compression. I've heard on the grapevine the colour science has been improved immensely due to MUCH BETTER noise filters and HAS BOTH the DCT-based JPEG AND JPEG-2000 wavelet-based compressed still files at up-to-full 4:4:4 colour sampling. It will the FIRST of many cameras in this new-format side-grip-style, combined video/stills bodies.
This is understood to be within certain engineering circles the FIRST Canon camera that will be ALLOWED by Canon Management to cannibalize the camcorder line AND their 6D/7D lines. It is said that executives are currently deciding HOW to fold multiple lines together on the midrange and simply push out ALL cameras to being part of either a low-end consumer line or a premium high-end flagship model lineup.
ALL cameras be reduced in terms of the number of available models. The R mount style is to be used on ALL APS-C and FF models from here on in! And right now the rumour mill has it that the 6D/7D line is GONE !!! Kaput! Sayonara! Auf Weidersein! Bye Bye! The M-series and Powershot series ARE BEING LOOKED AT to being merged into a single set of five camera models! The 5D and 1D series will be kept as-is with only a mount change sometime in the future. I should also note that the TRUE head scratcher model is rumoured to be an IP-68 RUGGEDIZED 60 fps 4K video Action Cam larger than a Gopro Hero-7 and WITHOUT the fish-eye look but rather just a wide angle setting at possibly 24mm! It possibly has a 2/3rds inch sensor in it.
That's my info from my Euro sources ... I'm betting the XC-15 style won't be announced until CES-2020 in January and only out for sale AFTER NAB-2020 in April !!!
P.S. You should see my 50.3 megapixel TRUE MF-sized sensor combined stills/video camera I'm using right now!
Wait until you what is coming out in terms of NEW and AWESOME camera technology coming out soon enough!
