Just another noisy sensor with too small of photosites....ala 50D
I think if people bother to read DXOMark's article which compares the sensor of the 500D/50D vs D5000/D90/D300s, they’ll learn:
(i) “Canon EOS 500D sensor is (nevertheless) an exceptional sensor with a very small pixel pitch and very low RAW noise”
(ii) “the Canon EOS 500D is a bit more color blind in comparison with the Nikon D5000. To compensate, a greater degree of color processing is applied, which increases (chroma) noise”
(iii) “Canon EOS 500D behaves the same way as many other Canon cameras… that is, the readout noise becomes predominant and… explains why the Canon EOS 500D’s dynamic range does not increase between ISO 200 and ISO 100 and obtains only 11.5 eV as its maximum dynamic range measurement”
(iv) Pixel size has NOTHING to do with the 'poor' performance of the 50D/500D sensor
Mind you, even the el cheapo D5000 has better dynamic range (12 stops) @ low ISO than the expensive, FF, low pixel density 5D2 (11 stops).

Nikon is in dire straits now financially. They must also have learned it's a bad idea to release the D700 so soon after the D3 'cos it literally kills the sales of the latter. You won't see the D700x for several years unless they're ready with the D4 upgrade.

I don't think that's true, I've worked with 3 guys who own D3s, 2 of them bought after the D700 release, and I don't know anyone who owns a D700, small survey size yes, but it shows that there's people out there prepared to pay the extra for the D3.

Let's get this thread up to 100 pages by tomorrow.
What else can we talk about?
I know, do you think it will take the same battery as the 5Dmk2?

More leaks.. this time from Taiwan... the official Canon announcement in mandarin. See
here as well as here too
Salient points:
0) Sensor size is 22.3 x 14.9 mm. That is a 1.6x crop.
1) Wireless flash control for Speedlite 580EX II、580EX、430EX II、430EX、420EX
2) Available end of Sep
3) AF with f/5.6 or faster lenses
4) 19 AF points only. No more. But AF points can be grouped into 5 regions for AF tracking.
5) Exposure compensation extends to +/-5 eV
6) Spot metering can now be tied to individual AF point
7) New imaging sensor electronics and design improve signal to noise ratio. Base ISO from 100 to 6400. Top ISO is now 'only' 12800 (NOT 25600).
8) LCD is new Polymer Network LCD that will supposedly still work fine under sunlight illumination.
9) Battery is LP-E6 (same as 5D2)
10) HD video in 24/25/30 fps and 720p video in 50/60 fps
Just added:
11) Full weather sealing

They are talking about 100% viewfinder, currently found only in 1D/Ds series.

I am glad it uses the same batteries as my 5D2, now that got rid of both my 5D and 40D

Ok, thanks. Is it true the VF magnification is 1x?

IF true, it would then be very close to the 5D2 VF size (69% of FF frame size compared to 71% for the 5D2).

Yakim that's at least 18 months old and it may have been Chuck Westfall in an interview I read. It was definitely a Canon representative. Whether that sentiment is still true I don't know, but so far no EF-S L, even though 2 of them are L optically.
It seems Canon is bent on making nothing but L lenses and EF-S lenses.

If this is correct, then it means that it is a new AF system and not just the system from the 1D series cameras. It will be interesting to see exactly what the AF system is. Is it based on the diamond pattern from the XXD series or based on the 1D series? Are there helper points for tracking or not? These details will be important.
