Please! oh pretty please CANON, do put in a decent passive AND/OR active cooling system into ALL your new cinema and stills cameras! AND please introduce an f/4-f/5.6 135mm to 650mm zoom lens with PREMIUM QUALITY glass for all APS-C, Full Frame and Medium Format R5, R6,R7 and R1dx/R1mf stills camera and your upcoming Cinema EOS RF-mount/PL-mount video cameras!
I have a PROPOSED HEAT SINK DESIGN which MAY work for you!
It costs about $120 US to add to a camera, but YOU (i.e. Canon!) should be able to bring that costs down to less than $60 US per camera. We end-users would be MORE THAN HAPPY to pay that $60 US if we can shoot lots of stills and videos at DCI 4K 120 fps and DCI 8k 30 fps and/or 60 fps UNHINDERED by heat problems for a full 12 hour production day, which is the NORM these days for commercials, studio work and even weddings!
See below attached image for proposed heat sink design!
Down below is an attached JEPG image that details an OPEN SOURCE hardware design under GPL-3 licence terms that is for a general purpose heat sink applicable to still cameras, video cameras, smartphones, tablets, standalone computers, embedded devices and peripherals with ALL them being of any form factor and design!
You can use multiple thermal conductor and/or thermal insulator materials which SHOULD BE MATCHED to the thermal radiation rates of the components, the heat transfer pipe/plate pathways and the desired amount of thermal storage capacity for the camera runtime required.
Again .... THIS IS AN OPEN SOURCE GPL-3 hardware design created by me on August 13, 2020 and is free for use under open source GL-3 licence terms!
OF COURSE YOU MUST DO YOUR OWN THERMAL ANALYSIS, SIMULATION AND TESTING before you make your products using this or any derived design available for sale or use as this design is a mere unfinished testing and design prototype and has NO WARRANTY and NO expressed or implied fitness-for-use made by me HarryFilm! This means Use and/or Modify it at your Own Risk and Own liability! I ain't responsible in any form or manner for what happens!
MODEL IT AND TEST IT ON A COMPUTER BEFORE YA USE IS MY WARNING TO YA !!!!
