Canon EOS 70D officially announced!

I doubt the 7D will get a brand new sensor just because it doesn't make any economic sense for Canon to do so.

You could bet your house (or your parent's house) on the fact that Canon will be researching new sensor technology to try to improve them for still shooters. And when (if) they do develop a new sensor with better noise control and dynamic range then you can also bet that they'll start sticking it into the whole range as soon as possible.

Some people have speculated that the repeated perceived delays to the launch of a 7D replacement are due to the developers having problems with such a sensor. After all, it would be simplicity itself to stick the 70D sensor in a 7D MkII with two Digic 5+ processors for 10 fps and a dedicated AF processor.

I never said that they aren't researching new sensor technology. If you had read my last post carefully, I said it doesn't make any economic sense to develop a new sensor specifically for the new 7D MK II.

What, just like it didn't make sense to develop a new sensor for the 7D?

But will they develop *two* new sensors - one for the 70D (which will filter down to the rest of the line eventually) and a different new one for the 7D II?

There is rumor of a 24mp sensor in a 7d2 prototype floating out in the field somewhere

The 70D sensor is already a brand new design.
It's hard to imagine that Canon will come up with yet another brand new design for the 7DII.
Rather, it's much more likely that the 7DII will use the 70D sensor - or some variation of it.

One of the rumors that's been flying around, for example, is that the 7DII sensor will be 22mp.
The interesting thing about this rumor is that if the 70D sensor is made slightly larger - 1.5x crop vs 1.6x crop (as on the 70D) - such a sensor will have 22.5mp.

So, if this rumor is correct, it's quite possible that the 7DII sensor will be just a slightly larger version of the 70D sensor (1.5x crop vs 1.6x crop).
Technically, this will be a new sensor. But in reality, it will be the 70D sensor with an extra ~1mm appended both horizontally and vertically.
That is, the same sensor, really, just slightly larger.

According to information on the Canon USA website, the 70D's sensor is already slightly larger than the sensors for nearly all previous Canon 1.6x crop-sensor cameras, 22.5x15.0mm versus 22.3x14.9mm. The difference is small, slightly less than 1%. A 1.5x sensor, such as the ones Nikon uses, would to be 24.0x16.0.

I believe that only the original Canon Digital Rebel 300D had a 22.5x15.0mm sensor. All subsequent Rebels and xxD cameras used slightly smaller sensors.

If Canon went to the larger 1.5x sensor, I would be worried about corner coverage on EFs lenses.

Yup, a good reason why it ain't gonna happen. Canon have finally got rid of the compromise APS-H format, why would they want to introduce another?

Fun to look at old rumors of the 70D and also to see just how far off they could be for the 7dm2...

The next EOS
The next DSLR Canon is going to announce is the EOS 70D, we’re trying to confirm if it will come on April 23, 2013 as previously reported. Below is a spec list put together from various sources that have written in. All of it seems plausible and almost expected.

What to expect from the EOS 70D.

18mp Sensor (Same as SL1)
DIGIC V (no one has said it will get DIGIC 6)
6.5fps
SD Card
Wifi
GPS
3.2″ Touchscreen LCD (No mention of swivel)
Magnesium Alloy Construction
Weathersealed
Slightly larger than the EOS 60D
$1199 USD Body Only

The price was spot on!

I sure do hope this happens. I have been waiting for it for four years now.

It'd be very helpful to have a 1.6 crop body with noise performance exactly as good as a 1D Mark 4. That's all I ask from the next crop body - give me that and I will buy it.

They packed 16MP into an APS-H sensor 4 years ago. I think 4 years is more than enough time to figure out how to get the same noise performance from the same number of pixels in an APS-C sensor. I think the reason it hasn't happened already is because Canon decided that they would get better return-on-investment from research put into other things, such as video focusing and wifi.

I agree with Tom and have said it multiple times.

give me 18 super clean megapixels, wifi, dual pixel live view and I will buy a 7d2 ASAP!

I dont want more pixels. I want clean, low noise 1.6 crop. I think most other people who do wildlife do too.
I hope we get it soon.

Filter down technology usually starts at the highest price point, then filters down(ie 7D>60D>XX0D). It rarely filters upwards. Not saying it doesn't, but it's not common practice.

DPreview just posted additional info to their 70D preview.

70D are already in store here in Brisbane at JB HI-FI thought release dates late September.
Looks tempting
