Ok, I'd like to start by saying I am not one to speculate on these new camera threads. I usually sit back and read with amusement all of the wild theories people post.
That being said, the recently leaked "5DX" camera images are of high enough quality that we can make some calculations of total sensor megapixel count through simple mathematical relation of the image on the screen to what we believe is a reasonable screen resolution canon may use for this new model. Why are we able to do this with some limited accuracy
The photographer has the guinea fowl on screen at 100% magnification and the size of the zoomed window relative to sensor size is clearly demonstrated on screen!
Here is what we find:
Screen size from African spy photo shot = 49 pixels on X axis by 49 pixels on Y axis. This gives an approximate screen area of 2,401 pixels.
The zoomed sub window is (and this is approximate to within one pixel) 6 pixels on the X axis and 4 pixels on the Y axis. This gives an approximate screen sub area of 24pixels or 1% of the total sensor sample area.
If we further hypothesize that the LCD screen used in the next generation of camera is the standard 902k dot 640x480 (and not a new 1280x720 version), this ratio provides a final sensor resolution of APPROXIMATELY 6,400 x 4,800 or 30.7MP. I urge everyone to take this with a huge grain of salt but it is an indication that this new camera supports a higher resolution than the 1DX. This calculation is only valid if the bird is at 100% on screen. any zoom amaount lower than that only increases the megapixel count.
Thanks. I was thinking of doing something like that, but I figured I'd sit back and let someone else bother with it all and I also wasn't sure about it since the tiny white sizing dot was so small that I had doubts about precision and being able to tell 18MP from 30MP.
Anyway if you are correct, and say it is 32MP, then with eosfun saying that one of these was wrong:
19 pt AF with digic 4 assist
well that would give us 32MP, 6fps, 19pt digic 4
the only think that doesn't match is why would eosfun say many might keep their 1Ds3, who would keep a 1Ds3 over that? maybe the AF is just a feeble 7D update still much worse than 1 series or maybe he simply was thinking of those few for who weather sealing and 100% VF are simply critical at all costs? maybe it is simply plain old 7D AF and the digic 4 AF processing assist was a minor point he simply wasn't commenting on (7D AF would be a bit disappoint IMO since I feel the 5D2 center point actually works better as often as not, other than that the specs seem fantastic though)
this body would leave them matching Nikon res and the 6fps would beat D800 even and be just enough to be useful and yet not quite so much as the 7/5fps of the CR/aqua rumor as to hit the 1DX hard.
it fits when he said the canon marketing talk said it will make the 5D stills landscape/wedding crowd happy while bring in 7D goodness which a 32MP, 6fps with 19pt AF would do.
But then again this probably can't the specs because
30MPish, 6fps, between 7D and 1DX AF, moire-free video are the exact specs I've been whining about for them to put in the 5D3 for the last 2-3 years and when have they ever listened to my crazed forum rants?
