6d2 came in $100 less than the 6d original price and the 5d4 the same as the 5d3. I would expect the 7d2 with whatever specs it ends up getting to be in that same boat. $1700-$1800. 30mp, 1/2 - 1 stop increase in ISO performance, and 12 fps would work for me at $1600 street pricing.

30 megapixels on a crop sensor seems like a horrible idea to me. Diffraction is going to be horrible. I can't imagine you'll be able to shoot any further down than f5.6 maybe. My Olympus E-M1 has a pixel pitch of 3.72, and diffraction sets in around f5.6 depending on the lens. The 80D with 24 megapixels has a pixel pitch of 3.73 so in theory, the diffraction limit would be roughly the same. I don't know the math behind it, but add another 6 megapixels and the diffraction limit will come down even further. If you want to shoot landscapes, or anything else requiring deep depth of field, you're going to be getting some really soft images.

But diffraction is purely a characteristic of light trying to squeeze thru a small hole (diaphram), and the SIZE of the sensor/image dictates the magnification factor for the original image when projected to final print size.
So visible diffraction is smaller for a larger format (e.g. 4x5") than a smaller format (e.g. 135) than an even smaller format (e.g. 4/3) because 2x enlargement makes an 8x10 from 4x5, 8x enlargement makes an 8x10 from 135, and 16x enlargement makes an 8x10 from 4/3.

Grain size in film does not make diffraction more/less objectionable, and similarly the pixel size on digital does not make diffraction more/less objectionable either.

Just bring it out before 2018 spring migration and tell me where to sign. I am addicted to 10 fps, could I have 12, please.

Aww man, just when I think I have everything figured out, I get debunked :-( that's really interesting, and I never thought of it that way.

30mp? keep it at 18mp...and improve noise! Give the MP junkies a 5DcII :)

I agree..keep it at 18-20mp make it much better at high ISO and get rid of the AA filter and I would be on board

Anyone else catch this rumor?

Rumor on Canon 7D mark III (external link)


Specification-wise we have this list, based on what we have been told so far, with some new bits (please note: I rate the specifications CW2)


  • New sensor technology and resolution around 28MP (we reported first)
  • 4K video (though no details, we reported first)
  • C-Log
  • More dynamic range than 7D2
  • Better ISO performance than 7D2
  • Tilt-able display with touch interface
  • New generation of Dual Pixel AF
  • More video oriented than 7D2
  • Higher feature set compared to 7D2
  • Same introductory price as 7D2

Why is Canon turning most of its dSLRs into video cameras so much in orientation?!
It builds video cameras already, is it also turning those into dSLRs in orientation?!
Is it being a lemming and moving into the doom of 'one size fits none'?

Not too long ago folks were shrieking that 18 MP was way too much, way too noisy. Let's just stick with the big pixels in 8 MP cameras.

But the fact is that as megapixels have increased over the years, performance just keeps on getting better. IIRC this general trend was pointed out by CyberDyneSystems in a post of a few months ago.

+1
If those rumors are true it's a total change to Nikon 500 for me,It's a sports/wildlife camera nobody cares about 4K and get rid of that AA filter!
