The Canon EOS R3 specs remain a closely guarded secret, but leaks have revealed that the camera could have a 45MP image sensor capable of 8K 30p video, along with a "resolution trick" that could achieve much higher megapixel output. 

The official announcement about the Canon EOS R3 (opens in new tab) has revealed precious little: it will have a newly designed, Canon-made stacked backside illuminated sensor with continuous shooting speeds of 30 frames per second (both matching the Sony A1 (opens in new tab)), with "next generation Dual Pixel AF" possessing a new subject detection algorithm, along with the return of Eye Controlled Focus (opens in new tab) that enables you to move focus points by moving your eyeball.

However, thanks to new leaks, we can now fill in some of the blanks left by the official Canon spec sheet. According to (opens in new tab) Canon Watch, these are the key specifications for the Canon EOS R3: 

• 45MP image sensor
• Quad-Pixel Autofocus
• 60 fps with full Quad-Pixel Auto-focus
• 20 fps mechanical shutter
• 30 fps electronic shutter (confirmed)
• New white balance system
• 8K / 30p RAW shooting

In addition, both Canon Watch and Canon Rumors reported that the R3 will possess a "resolution trick" (opens in new tab), in the form of pixel shift shooting.  

"The EOS R3 will have a pixel-shift feature on board (it was already rumored, and there is also a patent)," wrote Canon Watch. "Pixel-shift would allow to have a higher resolution than the native sensor resolution."

So, how much of this needs taking with a grain of salt? The answer, of course, is 'all of it' – however, some things seem more likely than others. 

The 45MP sensor and 8K 30p are both a given, as far as we're concerned, given the specs of the Sony A1. However, Quad Pixel AF seems a little suspect – Canon has already announced that the R3 possesses Dual Pixel AF, and would almost certainly be crowing about Quad Pixel if that was indeed on the table. 

We'd be delighted to be proven wrong, however. C'mon, Canon – spill more beans!
