A Sony & Canon Sensor Partnership Mentioned Again [CR1]

Re: A Sony & Canon Sensor Partnership Mentioned Again [CR1]

what so many people seem to forget is that Sony sensors work better at low ISO and canon sensors work best at high ISO. Nobody is best across the board. I think it would be a step backwards for the industry to just pick one.

Another point that needs to be made is that you can outsource the production of your design. It is very possible that Sony can produce a Canon design of sensor more economically than in house at Canon.

This entire thread is wild speculation. We know nothing. Time to relax with a good book or go take some pictures. The universe will unfold as it will, no need getting upset or excited over such small things...

Which is why still like the idea of Canon taking their own sensor at 50MP and officially implementing the Magic Lantern hack for dual ISO to increase DR. But I wont complain about having the Sony

I think the 7D mkII was in development perhaps 3 years ago and making such a change would probably delay production for yet another year.

I hear what you're saying, but the same point could be made for the FF cameras to be released this year and to which this rumour refers.

Their development and marketing life cycle is only separated from the 7D II by a few months.

Consider that Canon may have been perfectly happy with the sensor performance of the 7DII as designed and felt no need to use Sony crops. 7DII buyers seem pretty damn happy too.

Whatever gives us the best sensor.

BTW, I was looking over at this site and was intrigued that even for Nikon, the D4 and D4S sensors were not from Sony. The site has them listed as Nikon, but I wonder if it is someone else.

http://www.senscore.org/

The D3/D4/D4s and actually most of the low end Nikon sensors (Currently) are Not provided by Sony. The High end Nikons never have been. The Low end Nikons are mostly Toshiba Sensors, the D4/s is Nikon designed and made by Renesas . The D800/810 uses Sony (obviously).

Absolutely, and I think that philosophy will translate into future FFs too.

This also may be an opportunity for canon to retool their own production lines while continuing to supply products. It's not uncommon for something like this to occur while modernizing a facility.

This is more likely to be someone's fantasy sensor, now churning around the rumour mills.

My thoughts exactly.

Sony has high resolution/DR and Canon has dual-pixel AF.
If we marry those two, we end up with high resolution/DR and dual-pixel AF - in the same package.

What an obvious, wonderful solution ... that is pure fantasy, I'm afraid.

There are many reasons why Canon will not switch to Sony sensors and
is unlikely to cooperate with Sony on sensor manufacturing at this time.

The rumored 50MP resolution is also fantasy, IMO.

My bet is that Canon's high-resolution camera will feature a 40mp/high-DR Canon sensor.
Let's see who will get it more right 8).

Look at the DR difference between Sony and Canon at High ISO (rather modest, I mean what, like barely 1/4 stop worse than the 6D? and actually like at least a 1/4 stop of more better than 5D3) and at Low ISO (huge):

Look at the SNR (Sony actually ahead at High ISO, if anything, although it's basically all within the margin of error and nobody will notice any differences on this plot even if the data is exact anyway):

So....

My wish is a 36+MP high DR sensor, with nice 4k and non-crippled video usability basics and non-waxy quality and that can deliver at least 6fps in some form or another (even if just in an APS-C cropped mode). :D

My guess is a low DR, 40-50MP sensor with crippled body specs (4fps and no true cropped modes at all, never mind with more speed) and crippled 1080P. ;D

Unless Canon becomes the old Canon again, in which case maybe it will be my wish.

It's seemed like lately Canon sensors have been falling behind Nikon (Sony) in dynamic range performance. Would love to see some Sony sensors in Canon bodies w/ Canon glass. That seems like a winner all across the board.

So....

The downsampling in the DxO testing methodology may have something to do with that. Roger Clarke has for years, if I understand it correctly, stated that Canon sensors are the best for low-light, astro-photography and he recently called the 7D2 sensor a game changer for astro and it had something do with an advancement in dark current at high-iso (I'll go find his post later if I have time, I don't recall the details and I could be wrong). Regardless of the details, it's perfectly plausible that whatever advancement Canon has made with the 7D2, dual-pixel AF, and possibly other tech that we don't know about has given them enough to do a cross-licensing deal with Sony. If they had just wanted to use Sony sensors without something to trade it may have been too expensive or they may have had to give up control of other sensor design. Bottom line is that if this rumour is true it very likely is only happening now because Canon finally has something that Sony also wants.

Well astro performance is something a bit different, it might be that Canon is best for that, but otherwise it seems to be kind of a wash at high ISO at this point (and even with Sony ahead if you look to their high ISO-tuned Exmor used in the A7S).

let us see what Canon are showing up, I don't believe in a second that Canon are using a Sony inside their new cameras with higher resolution, it would be a slap in the face of Canons own sensor division

Many people suspect Canon used a Sony sensor in its PowerShot G7 X.

In any case, Canon is a business. If the higher-ups they believe they are better suited using a sensor built by someone else, either temporarily while they re-tool, or indefinitely, that's what they will do.
