They should also be able to make 1.6x sensors at least on par with those found in Nikon, but apparently they can't.

Wrong thread :-o but anyway:

"Apparently" - but appearances can be deceiving. The other possibility and the one I believe is that Canon doesn't want to because they'd have to invest more ¥¥¥ than they'd get a return of invest.

True, Sony has some important patents, but with the new 20mp crop Canon chose to go for other features like live view / video af and keep using their older sensor fabs/process. Why? Because *even* if the 70d sensor would be on par with the d7100 Nikon would still keep the more aggressive marketing and specs like af points, so why would Canon even want to try to match them here? They seem to be doing alright just the way they are, crop is "good enough" for mass production, ff for iq/low light.

I am not sure how the low DR affects their sales - but this is something that becomes known to the "general public" as well, you can find it in the Amazon reviews, etc. Even the vague mentioning of the Canon sensors being inferior to Nikon ones has its effect.

Yes, it is the wrong thread...

Crazy time for Canon to be sticking to the high price AND NO REBATE for its 24-70mm 2.8 II. 

My version I of the Canon needs replacement, now nine years old.  Hope the Sigma comes out soon.

Nikon Crop sensors are slightly larger. Canon APS-C is 1.6x crop, Nikon APS-C is 1.5x crop. So for camera bodies with the same resolution the Nikon should be able to offer slightly better IQ.

True, but it's not the slight size advantage that is making the difference, it's the construction of the sensor itself.

And I'm sorry I somehow had posted this in the wrong thread!!!

As for the Sigma 24-70 f/2, apparently that was a pipedream...bigtime!
