1Ds Mark IV & 5D Mark III [CR0.5]
« on: September 14, 2011, 11:30:46 PM »
Spec lists I just wrote in the last post that I wouldn’t post detailed spec lists because they’re rarely, if ever true.

However, it looks like [NL] received the same email we did. I’ll post the spec list now for your entertainment.

5D Mark III

  • 24MP
  • Pro grade AF (not 7D like)
  • 2 stops better ISO than 5D mk II
  • Digic V
  • 6 fps
  • New video codec, not Raw. MPEG 4:2:2, new video functions such as tracking focus in video mode
  • Compact body with improved weather sealed
  • Same introduction price as the predecessor

1Ds Mark IV

  • 54MP (no low pass filter)
  • Decent 6400 ISO performance
  • Same AF as 1D Mark IV
  • 14 stops DR
  • 16 bit Raw file (mode to be confirmed)
  • Digic V
  • Limited new HD video function in comparison with the 5D III

New GPS and wireless device accessories will be introduced around the same time.

Other bits of information from the same email.

  • All current L lens  can perform at the level of the 1Ds sensor resolution,there is no low pass filter in front of the sensor  and there is  digital on/off software switch to reduce moire.
  • Video function in the new 1Ds is not as  complete  as the one on  the 5D mk II and due the massive data reading of the sensor there is  no MPEG  4:2:2 coded.
  • It seems that in one of the prototype there was an option to shoot 16bit Raw  files that this option cut  down dramatically the fps.
  • It’s rumored that Canon will also announced one zoom and 2 prime lens with the Ds camera.

As I said earlier, I’m not a big fan or believer of  in-depth spec lists on cameras that are still more than a month away from announcement. If I didn’t post this, I’d get a ton of emails since it appeared on another popular rumor site. Rock and a hard place sort of thing.

Check the previous post for something I think is a bit more believable. I do hope some of you can point out any obvious flaws in this spec list that I have overlooked. Have fun!

It sounds good, but so good I'm a bit suspicious, more "wish list" like then "reality"...or at least it's too good and if I thought it were real I'd probably get disappointed when it isn't

New GPS and wireless device accessories will be introduced around the same time.

Here's to hoping it's some sort of reasonably priced modular system; either in body, or in the case of the 5DIII, in a battery grip.  Either GPS or wireless would easily fit in a form factor similar to an SD card.  Maybe give two modular bays on 1-series cameras, one on 5-series body plus one additional in a battery grip.  I could see at least four obvious applications for modules.  GPS, WiFi, Data Verification, and High Volume Workflow (Bluetooth to associate a barcode scanner, etc., like the 7DSV).

Meh...  Perhaps it makes too much sense to actually happen.

54MP?

Assuming square pixels, FF area of 864mm^2:
sqrt(864mm^2/54000000Px) = 4 micron pixels.
Not 4.##, but exactly 4. Suspicious.

Similarly, for 24MP sensor, pixels are _exactly_ 6 microns.

just realease the next gen already ... :) it's frustrating for a guy who invested more than 15k in lens to see that other manuf. have better options already released. :P
that guy is a friend... and i see him getting sadder day by day... :)

Citing the higher sensel count as reason for limited video seems odd. Its a CMOS, you can read only those sensels you really need.
Would be something different if we're talking about digital pixels, those also would allow for much greater DR.  But not mentioning such a change in concept?

What you're missing is that the megapixel counts are never exactly "000,000".

21MP ends up being 21,123,456 or some other odd number. Thus the "suspicion" in the "exactly" 4 or 6 microns is a result of your math assuming perfect numbers that won't exist in reality.

Without XLR and ability to record externally through HDMI it will remain an ambitious camcorder...

Nevertheless, it's interesting to see if the rumor holds up, 4:2:2 is a welcome improvement. Wont make me replace my Mk II for still photography though...
5D III -  Zeiss Otus 55mm 1.4 ~ 24-70 2.8L II ~ 70-200 2.8L II IS USM ~ 100 2.8L IS USM Macro ~ 16-35 2.8L II ~ Canon Extender 2x III

with same introduction price as the 5D Mk II it will be the real deal. If both has Digic V then I wonder if 5D Mk III will be capable of 16-bit raw ?

54Mp? Why I don't believe in this?

P.S. Only medium format cameras (like Hassel) can produce such numbers with more-less acceptable noise. But they are not so fast as they could be and files are huge. I would devide this number by two or so for FF bodies.

I understand that, but lets assume 54MP is between 53 and 55 MP - that makes the pixel size bounds 4.03 to 3.96 microns. For 23-25MP, thats 6.12 to 5.87 microns. These bounds are extremely narrow around the nice, even numbers given in the spec.
Existing Canon DSLR sensor pixel sizes are far away from any even/comfortable number - 5d ~6.40, 7d ~4.31, and 1d4 ~5.68
So, I'm just saying that the particular resolution numbers when presented as a pair like in this rumor, are dubious.

5D Mark III
    * 2 stops better ISO than 5D mk II

Take a look at how DxOMark scores have evolved. I'm  calling BS on this. The Nikon D5100 is only about 1 stop better than the aging (2003) Canon Rebel.  The (2005) 5D classic still soundly beats any APS-C sensor, and the 5D mark II gained a little less than half a stop.

A true two stop improvement is indeed implausible. But as there is no agreed upon definition/method of measurement that doesn't say a thing anyway.

I think there might be a misinterpretation at this point - not 2 stops better ISO, but 2 stops higher ISO. Which means that sensitivity is expandable up to ISO 102,400
FF + primes !

That's how I interpreted it - 'better' as Canon defines it, i.e. 'more' and not 'higher quality'. 
EOS 1D X, EOS M, and lots of lenses
