I think the reason for the blackout is that the CPU can't handle having LV and doing a write at the same time, it might just not have enough RAM or computational resources to multitask. I doubt card speed has anything to do with it beyond a baseline.
Hopefully it's a firmware situation with unused resources... It is very annoying and jarring though not the I chimp
No doubt you're right- I mention the cards because it will help to eliminate one variable, it's not too expensive, and is fairly risk-free.
Hopefully Canon's 'round-two' of the EOS-M will reverse their fortunes; there's just so much potential with mirror-less.
--Potential of mirror-less according to me--
Just laying out my thoughts on this, please respond if you disagree!
Essentially, given that autofocus can be spread across the sensor, and that both the autofocus readings and the sensor data are being streamed real-time, a mirror-less camera could feasibly have the most flexible and accurate autofocusing system of any camera on the market. Processing power is the limitation here, but myself along with my fellow computer geeks know that this limitation quickly moves ahead, and especially so when a demand is realized by the market.
Further, given that autofocus is done constantly and that the sensor is constantly looking through the lens, a mirrorless camera has the capability of being the fastest shooting system available- as others have alluded to on this forum, Canon is looking keenly towards video even to what seems to be the detriment of their still camera technology. I back this theory up with the progress that has been made in solid-state drive technology. The latest drives, which skip the SATA protocol altogether and connect directly to the system bus, as in the latest Macbook Air (and coming Macbook Pro, if it isn't here already), can exceed 1GB/s data transfers. And that's just using a modified controller; the bandwidth could be ten times that amount using today's technology, and we know that bar just keeps moving.
So, in summary, I expect that Canon could produce a mirror-less camera that could track literally anything with perfect focus while shooting full resolution at ridiculous frame-rates; I'll throw 60FPS out there as a mark, but I'm betting that they could easily exceed that if they just made use of the full technology on the market today.
The downsides would obviously be the cost associated with developing and manufacturing the processing capability, and the body would need a much larger battery than what goes into the current EOS-M; but if the 1D series is the standard for a 'Pro' camera, how hard can that be?
