Sony A9: Is Canon doomed ?

A camera sitting on a desk, not in sunlight, while recording video and halting multiple times after around a half hour of recording...is not 'trying hard to find a overheating issue' IMHO.
He's not trying hard to create a situation for a 'problem' to manifest, it's simply happening in not-at-all-challenging circumstances!

My bad...after watching it again, it's indeed video and not stills.

Yeah, overheating after 30 minutes of video does nothing to change my mind that dSLRs or mirrorless cameras are 'still cameras' that are poor alternatives to dedicated video cameras...all the extra stuff you need to buy in order to use it better for shooting videos (microphones, monitors, video brackets/shoulder rests, quiet focusing lenses, etc.) ya might as well have bought a video camera for professional video shooting (like at weddings)! It is passable as a means of recording Johnny at his swim meet.

Totally agree ! DSLR's should only be used for video occasionally as their primary use is for stills. That's why seeing the A9 having issues with it's prime function raises huge red flags in my books !

But the A9 is primarily a high frame rate AF still camera 'for sports', 'with video capability' added...even the professional users who had an early opportunity to try out the A9 have a strong belief that an A9S better suited to video with S-Log is in the works, just like the A7RII (stills) vs. the A7SII (video) orientation.

I dont agree at all, dslr/mirrorless are fantastic video rigs.

how often do you need to capture 30 minutes nonstop anyhow?

Particularly in 4k or even 1020,. indeed.

Everything is a matter of degree...'Smartphones are wonderful still cameras and video cameras" is another subjective point of disagreement among those discussing the mission of a mobile phone.

no no no, the comparison is high end video vs high end video + added high end framerate and/raw video/global shutter.

it's not even close to your analogy of smart phone vs assumed large sensor camera.

Only slightly related, but re: video and what is the proper tool anyways.

I recall a thread on POTN many years ago, before DSLRs had video,. where in a the midst of a discussion of the Canon XL series camcorders, (which were very flexible as there was an EF lens adapter available) someone came in and proclaimed that "No professional videographer uses Canon. Look elsewhere, it's all SONY and Panasonic."

At the time I was coming towards the end of my time as a tech director at a large venue of 2,000 seats were coincidentally virtually every single professional videographer that came to work at my theatre used Canon XL series cameras, AND the night before I had watched a ground breaking documentary on polar bears that brought the viewer closer than ever before recorded,. due to the use of a set of Canon XL video cameras including one mounted to an EF 1200mm f/5.6 (with like 3x crop factor!)

My mobile device is my video camera. Does a great job !

Jake, is that polar bear doc available for viewing on a medium available to us today? DVD/Netflix/Amazon/You​Tube?

It was on Netflix at one point. I don't recall the name off hand.

EDIT, found it, but the date is interesting (2008) later that year the 5D2 was announced!

The problem with EVF cameras is that they are actually doing 80% of what is required to record video even if they are idle.

The full frame is read from the sensor at 60 fps, each frame is "developed", and then output to the EVF.
This requires a lot of calculations (which means heat generation) and the only missing steps are codec compression and recording to flash memory.

It is much more difficult to handle the thermal envelope in the A9 than on a DSLR. Let alone battery drain.
That is probably why Canikon have not yet come up with a convincing pro mirrorless camera yet.

It shouldn't be beyond the wit of man to develop an eye activation system that means, when using the EVF, the sensor is only energized as the camera is brought to a shooting position. It seems almost trivial and should greatly extend battery life as well as reducing heat generation.
