As we all know the announcement of this camera has been pushed into April 2013. There has been many speculation as to what the specs may be, in the past they say the sensor would be 24mp, now they say it will be 18mp and some say it will be 21mp.

What Gordon pointed out about the Nikon D7100 that I like is that the low pass filter was removed creating sharper images at it appears the low pass filter is not needed.

I want to seriously consider buying the Canon 70D camera if the sensor is significantly better than the t5i and t4i and if the low pass filter is removed.

Other wise that camera wont be worth the money for me.

No real final word as far as I see as to what the true specs of the 70D will be, and I really hope Canon follows Nikon in removing the low pass filter from the sensor.

What do you people think?

I think I will wait until I can put my hands on a 70D before forming any opinions. I am, really, thinking more about the 7D's successor, and the SL1/100D, in the 1.6x-crop arena.

On the other hand, I actually already have a DSLR camera with a notably weak AA filter, the Canon 5D! The 5D's weak AA filter might be why so many, including me, think it renders beautifully sharp default JPEGs.

I also have another camera, with pro-level controls and weather-sealing, with no AA filter whatsoever, a Nikon F6! :)

Life is quite good at present! My next acquisitions might be a Nikon SB-910 flashgun and Nikkor lenses, or a Canon L lens.

Seeing the sample images on dpreview.com, it appears the D7100 is not really a game-changer in image sharpness. Pixel-peepers will see a minor bit of an improvement, within a very small aperture range, it seems, and mostly with a better lens than the kit zoom. (In this case, f/3.5 to f/5, with the Nikkor 50mm 1.4G.) The removal of the OLPF appears to have little practical effect, for most shooters.

My wife is a Nikon D7000 shooter, and a very practical person; I doubt she will see a reason to upgrade cameras, especially as she virtually never shoots within the aperture range in which dpreview found an improvement in sharpness. I am probably more of a pixel-peeper than she, and see no reason to upgrade, at this time, to any camera simply because it is without an OLPF. Of course, the future may reveal new sensor technology that might make a more significant difference; I am not opposed to new technology!

Me personally I am interested to see what the Canon 70D will bring, its like I will buy either the T4i/650D or the T5i/700D, for reasons as price and that the 70D may not have a truly better sensor and other features.

I had spent a good while deciding between the 60D and the 650D, why i chose the 650D its because I dont need the 60d stuff plus the 60d has a lot of bottons from what I can see will be too inconvenient for me to use, the 650d has a very responive touchscreen which everyone i saw review that camera just loves, plus the image quality of both the 60d and 650d are not different.

It would be interesting to see what the 70d brings out!

If its true this camera will use the same sensor as the canon sl1/100d, I am a bit disappointed, I hope the 70d is better compared to the 700d than the 60d is compared to the 650d, with more AF points that are all cross type and hopefully other special features!

Same sensor, 18MP APS-C. Hmmm...

Same sensor as the 100D, which in itself is a brand new sensor.
So far Canon has released cameras with 4 different 18MP sensors; 3 of which are aps-c.
I am not sure what it is about 18MP that Canon is so fascinated with, but there is most likely a reason for it.

Well, according to the following web page, 19.5MP is the equivalent resolution to represent 35mm film:
http://www.design215.com/toolbox/megapixels.php
I've read other opinions that range 35mm film quality anywhere from 12MP to 24MP. So, my guess is that Canon thinks it's 18MP. This is where they're setting up base camp until they make the climb to something extraordinary; something that would leap past Nikon, like 40MP, which is only a 50% resolution increase (in each dimension). A 100% increase (or double) would be 72MP; and I think we all know that's years away (without going to medium format sensor).

If you want to play with the numbers, here's a nice megapixel calculator page:

According to canonrumors.com , check out the canon 100D/SL1 sensor as that sensor may be in the new 70D.

I am hoping there is some great features in the 70D, what I know what the 70D will have is a strong body. What I want to see in the 70D before I decide if I should chose that over the 650D or 700D is noless than 14 auto focus points spread out over the frame, with 9 points of more being cross type, I know there will be a fast shutter speed 1/8000 sec.

I cant really think of what else I want to see in the 70D that wont make it cost more than $1,000 USD body only, hopefully its something that will make me think this is a camera I want for the next 5 years or more!!!

There is a theory about the 18MP APS-C sensor being Canon's current practical limit. They manufacture their own sensors, and the process they're on is rather old. It's rather expensive to upgrade, so they're milking it for what its worth before upgrading.

Aug 24, 2010 - Canon has announced it has developed a 120 megapixel 29.2 x 20.2mm APS-H CMOS sensor.

Ok, I should have said, the process they use for mass manufacture of DSLR sensors is old. They could use different processes for compacts, or development.

They have been talking about a high resolution full frame camera to be anounced next year 2014, they say the pixel count will be 40mp, it may actually be 2 cameras, the replace ment to the 5d mk3 and the 1dx, i think the 1dx replacement may have the 120mp sensor. which ever camera has that sensor I might work harder and smarter to get the money to buy it,
or buy what ever replaces that camera!

That was my prediction too; 50% larger than 18MP is 40MP. I think they'll need that to compete with the Nikon D800 36MP. However, I would like to see one camera with APS-C 40MP sensor and one with full-frame 120MP sensor. :mrgreen:

Hey, a guy can dream. :roll:

Note a 40MP full frame sensor is lower pixel density than an 18MP APS-C. Scale up the latter and you have an easy 46MP already.
