I really wish Canon would stop playing around, and actually do something innovative. :

"Innovation" doesn't always mean better.

Canon is doing amazing things on the lens side, they're so far ahead of everyone.

Sensor technology is a bit harder due to patents. There will be good things coming, but rushing things out is rarely wise.

By defining "innovation" and "innovative" and suggesting that Canon is innovative, you two are destroying the lives of trolls and their families.

I think a few have jumped out of tall buildings already this morning. :'(

Lets not forget Canon already demonstrated a 120MP 5D prototype.

Hadn't seen any other MFG do that yet. Just saying... Canon DOES innovate... just not at the same pace as other people that have to scramble trying to compete against Canons dominance lol.

Hey guys, pretty sure pancakeman was being sarcastic

Definitely, people have a hard time recognizing sarcasm....

There was a story going around on Facebook and it provoked a lot of reactions.... I suggested that it was sarcasm and immediately got pounced on.... Despite the fact that the story came from a website that proudly proclaimed on its banner "Your #1 source of sarcasm".... If they don't get it, odds are that they REALLY won't get it.

And they often do so at the loss of usability and/or reliability...

So do these curved sensors mean the end of vignetting? Or of peripheral chromatic aberrations?

 

[sanj]

Is there anyone else use this technology yet?

And some people miss when others get it.

I am not convinced about this new Sensor-Concept. Most modern Lenses are telecentric, I doubt whether you need a curved sensor in these cases. So why have a curved sensor if you need it only for wide-angel lense? I am also curious about the stability and the lifetime of a benching sensor. If you permanently Flex a sensor, the material will perhaps be damaged. How many defective conducting pathes will make the sensor be unusable? Perhaps only one. And the more thick the sensor is, the more stress within the material is produced by flexing. If there is indeed a limited life-time of such a sensor you will Need an easy possibility to replace the sensor without dissasembling the camera.

I think this will not be a product for mass-market. Perhaps for cine-cameras?

It would also allow some interesting artistic effects..... Like the centre of the picture in focus and the outside deliberately blurred......

Yeah, but I'm sure there's already an app for that.

I too am curious about the potential use for a curve-able sensor. Would it help with lens design perhaps? to my knowledge, all current lenses were designed with a flat imaging sensor in mind..

That's the point. Current lenses often require additional elements to project a flat field, so a curved sensor would mean fewer elements, meaning smaller, lighter lenses and potentially better optics.

Great for Mirrorless potentially...

 

[fentiger]

i can see what could happen. Canon builds a new camera with new curved sensor, it stays flat with current ef lenses, curved with new curly lenses. and CURVED with 3rd party lenses.
maybe in a distant galaxy far far away!!

 

[Rlucas]

This sensor technology seems like it would be used for a compact full frame mirrorless from canon using the current lens line-up. Thoughts?

I do not believe, that it will be an Advantage to relinguish correcting a lens in regard to a flat projection plane. Canon is a Lens-Company - why should they give up their expertise in making good lenses?

In the case of wide-angle-zooms such an approach may result in an amount of changing curvature of the projection plan, that you have to adust the bending of the sensor in respect to multiple combinations of focal length (in case of a zoom-lens), distance and aperture. And it may be different in every single copy of an lense - remember that many extrem wide-angle-lenses are not adjusted exactly orthogonal to the plane of the bajonet. Nobody will do all those adjustments, its far too difficult.

Perhaps it will be interesting to have a curved sensor in the case of a Camera with a fixed ultra-wide prime. Something like a digital Version of the Hasselblad SWC.
