If they put in an 18Mpixel sensor, who says that it is the same old sensor?So, Photokina in September, what do we expect to see ?
I'm not expecting all, just some...
Canon EOS 7D MkII with 24mpx and next gen 70D AF tech
Canon EOS 750D with a 18mpx sensor and trimmed down 70D AF tech
Canon EOS M3 with same sensor and AF as 750D
Lol Canon 18Mpx sensor made it to most rubbish bottom model 1200D. Why do you expect they repeat this and put the same sensor into 750D and M3?
Safe bets for the future is that ALL of Canon's new DSLR sensors will be DPAF. Keep in mind that one of the reasons why the 7D2 has been delayed so long is that they are having problems manufacturing the sensor. (statement by Canon executive) They have no problems making the 70D sensor, so why is this one any different? They should be able to churn them out easily.... plus the camera will not sell as many units as a lower priced 70D so volume should not be a problem....
The most likely explanation is that there is new technology involved (also said by a Canon executive). This is either a new fabrication process, a new way of doing things, or most likely, both. I expect to see finer lithography and the migration of the A/D circuitry onto the sensor. This should give slightly better efficiency and lower the noise level.... and that's a big thing! drop the noise by two stops and you should be able to 5D3 IQ out of your crop camera. Of course, if this happens then the 5D4 will get the same treatment and the 2 stop advantage will be restored.
This has to happen..... it is only a matter of time. The big question is if the time is now?
