Canon Must Have Been Crazy!



First read, this is the latest Canon announcement they have just made today:-

http://www.imaging-resource.com/NEWS/1283221661.html

They must have been insane! What? A 202 x 205mm sensor?! That is, 8" x 8"! Is this a 8R photo printout? :-o

Oh well, when the 645D is still having a 44 x 33mm "large" sensor, what camera Canon is going to make to adopt their this new super large sensor? But do note that the 645D is already large and heavy! @_@

Okay, personally I think the recent Canon announced new developments doesn't make any sense at all, frankly, including the last APS-H 120MP CMOS sensor's!

Potential applications for the new high-sensitivity CMOS sensor include the video recording of stars in the night sky and nocturnal animal behavior.

I think this is more for marketing purpose, they have successfully developed it does not mean that it should turn into production....

The large sensor, in the article there is a photo comparison. They have got their dimensions wrong, 105 * 102 more like it. Still large by any standard.

But it is said that it is produced from a 300mm (12") wafer. Isn't it a waste if only a 100mm (approximately) chip is extracted?

I wonder how many wafers they have to throw away, in order to get just one working sensor? Must cost a small fortune!

However, put one on the end of a large astronomical telescope, and it may well be worth it!

Yes, I'm afraid that the yield must be very low, too.

The article is not specific, does not say that the pictures are or are not to scale. Does not state how many sensors per wafer are extracted. Getting 1 sensor per wafer, the failure rate must be huge and the cost. Does Aprii 1 fall in August in Japan.

It's sensor for special application - night animal shots, stars, other astronomical shots, night supervision and et.c., not for common photocameras.

I don't see the need to question this......First of all, there are a number of 'super telescopes' being planned for the next decade at research facilities across the globe - maybe this type of sensor could be used. 2. Being able to make really large sensors from very large wafers could lead to cheaper consumer sensors - as you could fit a ton of them on that sensor. 3. Spy satelites anyone? 4. Quite simply, this is for converting an old glass negative camera into a digital one. Screw old rangefinders, that is the only way to shoot......

lol

Seriously, innovation often means building things that on their face have no commercial purpose. Concept cars flesh out technological innovations

Right, this is not for anything near consumer. This is totally a move for industrial purpose uses like science labs, military, and perhaps for the movie industry. I can totally also see this being very useful for undersea footage where there is little light.

Nice post on Canon .....

I really liked reading your post!. Quality content.
A+ Grade from my side.

Why everybody is looking for a purpose with this lenses?
The 120MPxls APS-H is a prototype they will use to assess data flushing/processing, in other words: it will be used to help the next commercial sensors to work better.
This one, I guess it was a kind of challenge to see how big they can produce a perfect sensor. One more time, they had to improve lithograpic processes and these improvement can be used on next generation of sensor fabs to produce bigger (FF) sensors with less lost, so cheaper price.
And finally, all you can see from Canon is just basic Research and Development for such a sensor maker (Sony Semiconductors could have made the same I guess).
PS: and for telescopes, usually you need small sensors, not huge ones: to get a better reach (just like APS-C vs FF), and also reduce heating

Yes, I think you're right about telescopes: noise is purely a function of pixel-count, technology and operating temperature, I would imagine.

So for astronomy you choose a compromise between noise and resolution, and use elaborate cooling methods. The most appropriate sensor size would then follow.

Can you imagine the size of the battery and what would be needed to process and store the data, for any camera based on that sensor. It would'nt be something to go hiking with.
