Lame AF is showstopper for Alexa then too.

For all the people that believe that Cine camcorder markets and mirrorless markets don't overlap. I'm a perfect example that the DO. I sold my Sony FS7 and was literally 2 days away from buying a Panasonic EVA-1. Then Lumix announced the S1H and that stopped be cold in my tracks. I wound up buying the S1H instead and I'm perfectly happy about replacing my FS7 and (almost) EVA-1 with the S1H. I pre-ordered the A7S-III because I want one of my cameras to have PDAF and will add it as B-cam to my S1H. 
The rumored Sony FX6? Sounded tempting at first....but with the A7S-III, I no longer have any use for an FX6.
Yeah...the mirror less and pro camcorder markets DO overlap....substantially.

Guys....Canon never intended the R5 to "not" overheat. Overheating was known by Canon a long time ago in development. They "specifically" did "not" try to fix this problem early in R&D. Canon was and is perfectly fine with its recording capabilities.
My Canon rep friend told me "Cliff, the R5 will have strong recording restrictions"...over two months ago. And....he knew about this LONG before that. Again, Canon did not want the R5 to "not" have "recording restrictions".
By the way...Canon's camcorder division is perfectly happy with the fact that you can't use the R5 for long form event recording. This was part of the R5 plan from day 1 decelopment. You cannot use the R5 in place of a "camcorder".
Sorry....

Sigma does not have a professional camcorder line or business division to protect. Canon does and does not want us to use the R5 like a true camcorder.
This overheating problem and 29 minute time cripple was well known inside Canon during the R5 development.
I have a contact inside Canon that told me over 2 months ago "Cliff,...the R5 WILL have heavy video recording restrictions" He wouldn't tell me why or any more about it. But yeah,...if you look at my posts here and everywhere where I told people this. I was called a "negative troll" for stating this! See?
Anyway....Canon has always known about this are were 100% perfectly fine with it. Canon Cine division managers are perfectly happy with it too.

I now fear that Sony will think its OK to cripple their answer to the R5 with 29 minute recording restrictions. Im sure that is what XDCAM wants.

High technology at the cost of reliability and trustworthiness? 
I suspect that most of us here would have traded 8k technology and given it back in favor of RELIABILITY.
A Tesla is a very high tech car but what good is all that technology if the car breaks down all the time and leaves you stranded?
Canon should have used a SIMPLE "low tech" cooling fan. The R5 is going to have a 3-4 year sales life. Now?....the R5 is going to have to live with 3-4 years of hundreds of overheating YouTube video complaints. And rightfully so.
Canon created this mess and they will have to live with it.....
This was 100% their choice.
 

I mean...sigh...this is not the end of the world, I guess. You "CAN" still use the R5 for events if you plan it carefully.
Stage play - Use 2 R5's and start one 10 min later than the other. This allows one to force time stop before the other. Then just stager the record start/stops back and forth between them.
Your kids school singing play - Time your record stop when some other kid is singing to as to make sure your time is rationed in favor of your kids performance.
Wedding - Plan in advance with the priest. Setup a hand signal to let him know you are stopping. This triggers him to tell the audience...."we will now have a moment of silence for the bride and groom"...assuming the room is not hot, you can stop/start again without missing anything.
See?....the R5 "IS" doable if you PLAN your work and RATION your time wisely.

Yup,...that heat has to go somewhere. Without a fan, how else were they supposed to move it out of the body? Some people claimed that Canon developed some kind of new magic metal heat pipe tied to an invisible heat system. To most of us here, this was absolutely expected. Lumix did the right thing buy using a REAL active cooling system for unlimited 6k recording.
Something else. Canon and Sony can allow their sensors to run hot. But, hot sensors are NOISY sensors. More heat causes more noise. Cool sensors are cleaner sensors. This is why most large sensor camcorders have fans. To keep their hot sensors running cooler and cleaner.
Major screw up Canon. Let's see how that R6 runs.

Officiant: I now pronounce you hus... 
Video guy: WAIT! OVERHEATED! GIVE ME 10 TO LET IT COOL DOWN?! 

Maybe Canon will come out with an ice pack option:

There is a Spanish saying that goes something like:
"It's easy to talk $hit and not fear the Devil...until the day you see him standing at your front door"
We said and heard a lot of talk for the last 2 years about camera companies not surviving the changing market. Not everybody actually believed it. Today is a shock because the Devil is now standing at our front door. Its our first actual, "Oh $hit ...the Devil is real" moment.
More to come.....

Its not just the processor that needs cooling. Reading out a large sensor in 8k at 30+fps will heat that sensor up...big time. Its going to suck amps galore and get really hot. Sony often clocks their sensor readouts down to keep them cooler in small passive Alpha bodies. A fast clocked 15 millisecond readout in 8k 30p....in a passive cooled body?...no damn way!!!  That sensor will be clocked at 35-45 milliseconds and will jello-o like crazy. Even THEN,  it's still going to get hot. I'm betting on 8k clips no longer than 5 min and a required cool down in between clips. 4k?....be ready for pixel binning/line skipping and a forced 29 minute recording limit. You guys wait and see....the "Canon Cripple Hammer" is alive and well. They have to also make the Cine EOS managers happy too. 
And please.....nobody tell me; "Canon Cine EOS managers have ZERO concern for anything that an R5 has to offer"  or "The R5 doesn't compete with the C200 or C300 so Cine EOS managers don't even pay attention to the R5 because they are two different markets"
Oh...they care and the have a lot to say about how the R5 should be "properly" crippled.

We have been seeing these R5 prototypes out there for a couple of months now. Maybe with the final R5 production model, Canon will sneak in a proper cooling fan? Without that, I don't see how Canon can do this 8k/4K properly. The Canon C200, C300, C500, C700, all REDs, All BlackMagics, Sony FS5, FS7, F5, F55, FX9, All Varicams, EVA-1...and S1H have cooling fans to control sensor and processing heat in 4k/6k/8k. If the R5 really can do all that they say it can with no line skipping and/or pixel binning.. .in a passive cooled body? That would make the R5...THE..greatest electronics engineering marvel that man-kind has ever seen! Absolutely no question at all! It will literally make all the fan-cooled Canon Cine models look foolish. (And any other fan cooled 4k/6k/8k camera too) Hmmm...or maybe it's just me that is foolish for expecting all this incredible R5 8k/4k 10bit and raw capability to be fan cooled in 2020.
I'm telling you guys....the devil will be in the details, asterisks and fine print that Canon will only reveal the day this camera actually hits the streets and all NDA's are expired.

Canon is not talking abut the recording time limits that are going to be imposed. I have a Canon insider that tells me that time limit cripples ARE in this equation. Although he knows they exist, he does not know what those times are and he told me they were still being debated internally. So, it's not set in stone yet. (This info to me is about 6 weeks old now) Anyway,..you can safely bet your life that there will be video time recording limit cripples that WILL frustrate many people. I'm curious how they are reading out that 8k and making 4k out of it. Are they going to line skip or do a crude pixel binning process to save image processing work load? I SERIOUSLY doubt Canon will be able to do an on-sensor, "Sony-style" full pixel readout at the A/D converters. I smell some 4k line skipping from the full sensor width....hmmmm.

Panasonic is NOT being "stubborn" with PDAF. In order to have phase detect AF, you need to buy a sensor that has dual PDAF photosites. Sony sells them to Fuji, Olympus and Nikon. I'm told by somebody I know in the sensor industry that Sony REFUSES to liscense PDAF sensors to Panasonic "specifically"....by request from Alpha. Panasonic has no choice but to go the contrast AF road. This is a harsh marketing tactic by Sony and everytime Sony reads complaints about Panny AF....Sony Alpha is VERY ...VERY.....V E R Y....happy.
Panasonic is going to have to fix their AF complaints...on their own. Sony is NOT going to help Panny fix it! Sony can live with Nikon and Olympus as competitor's but they will NOT help their long time rival, Panasonic.
Believe me,....Panasonic is TIRED of hearing their AF complaints. They KNOW....believe me,...the know! They are doing the best they can with what they have.

If these A7S-III specs are right. Sony seems to be targeting the Lumix S1 but maybe NOT the S1H. I suspect that the S1H is WAY over spec'd for Sony to match in any "consumer" Alpha. XDCAM managers will demand that the future A7S-III will need to be crippled in very distinct ways. Alpha will want it to have everything and XDCAM would rather it not even exist at all. At some point they will agree and compromise with each other. The S1H is overloaded with an extremely high feature set that rivals an FX9 or even possibly Venice. Lumix is using Sony's own EXMOR image sensors against them!
10bit color is a must but what about Alpha's 29 minute time limit? Will Sony allow it to properly overheat to keep the high dollar pro's away from it? Rumors also say an FX6 is on the way...the cheaper, SD card long-GOP version of the FX9.
I suspect that the A7S-III is THE most hotly debated camera in Sony headquater meeting rooms in the companies history. 
The A7S-III's biggest enemy wont be Lumix, Cannon, Nikon or BlackMagic. Its biggest enemy will be Sony's own internal politics!
