hopefully the new sensor electronics for the 1DX brings forth improvement in dynamic range, Canon Achille's heel

Nikon D3S = 8.3 EV

Canon EOS 1D Mark IV = 8.7 EV

Canon EOS 5D Mark II = 8.4 EV

Nikon D3 = 8.6 EV

Nikon D300S = 8.4 EV

all at base iso.

so not really a overall achilles heel i would say.
if you mean DR in high iso ... well that looks not so good.

ok sony beats them all but .. sony is still no competition in the pro sector.
i rarely have a professionell customer who buys sony.

Can you point me to where you're getting those numbers from.  I've seen higher numbers quoted but possibly none are the definitive source.

A quick check revealed the 1D3 and 1D4 had 8 channel output

Hopefully the new sensor electronics for the 1DX brings forth improvement in dynamic range, Canon Achille's heel

I would expect so.  Technology has advanced... read noise is down even lower than 1D4 according to press release and in general the chip electronics have shrunk making more room for the photosite in each pixel.  Those advances combined with larger pixels should result in more DR.  Hopefully it will be close to the recent Sony sensors that are all over 13 stops.

Where do people see 16 bit images in the specs??  I see14 bit images in the specification, and 16 readout channels.

The previous model had 8 readout channels and 14 bits, and Nikon D3S has 12 readout channels and 14 bit images.

I'm not sure that the number of readout channels has much to do with the bit level of the image, I thought it was just pulling data from the sensor in parallel streams data can be read faster.

Doesn't the A/D converter determine the bit depth?

Yes, the press release stated that the 1DX will have a 14-bit ADC and that the new sensor will have 16 channel readout.

Yes, The maximum bit-depth is determined by the ADC.   A 14-bit ADC can encode 2^14 (16,384) discrete levels for the voltage at each pixel.

From a video standpoint, it's a bit underwhelming.

No 1080 60p is a big one. Hopefully, the next full frame will be a bit more video oriented since the 1D is more for stills people. For video, especially since they made us wait so long and Canon's refresh cycle takes longer than an Ice Age. The 6D or 5D3 or whatever it's called needs to have

1) 1080p 60fps
2) 4:2:2 50 mb codec
3) Hopefully a flip screen

That's not asking for much at all

The reason why the 5D2 was such a huge hit and considered revolutionary was because of the HD video. Without the video, it would have just been another camera. So Canon needs to do something revolutionary again for video. Maybe on Nov 3rd, the video people will finally get what they need

The video capabilities Canon put into the 1DX might be so that it doesn't come too close to whatever they're going to announce on the 3rd.

Direct quote from Dan Carr's web-site...  are you going to tell him to get a clue???

yep i do exactly that.

of course 1/500s or 1/2000s would be nicer then 1/250s.

but 1/250 or 1/300s that´s just a matter of more flash output, smaller aperture, a ND filter etc. and not a dealbreaker.

Smaller aperture or ND filter reduces the ambient exposure AND the strobe exposure.  If you have enough strobe power at your disposal then that would work fine.

So on one hand you agree that faster max sync speed is better and the other hand you tell me to get a clue when I say that 1/320 is better than 1/250 and that some photographers might be disappointed the max sync speed went down.  Ok.  You win.

  Another issue is the max sync speed is down to 1/250s which might bother outdoor shooters trying to overpower the sun with strobes... for example Dan Carr talks about his on his web-site.   Overall, as another member stated earlier today, don't forget Canon is in the business to sell cameras and they are building this camera for the possibly the biggest segment of pros... those working in the field (rough and wet conditions) who need fast shutter speed and low light performance.

there is much nonsense in your post but this is the worst....

do you think 1/250 or 1/300 of a second makes a big difference in overpowering the sun?

please get a clue what you are talking about.....

Direct quote from Dan Carr's web-site...  are you going to tell him to get a clue???

"Overcoming the ambient light with your strobe power is a constant battle for location photographers and squeezing every last 1/3 stop of shutter speed is very useful."

When using strobes outdoors to stop action it is important to minimize the ambient light and this is done by reducing shutter speed and/or aperture.  But reducing aperture also means increasing your strobe power to get the proper exposure.  Shutter speed on the other hand does not affect the strobe exposure.

Bye bye Canon, hello Nikon.

You won't be seeing me here anymore, good luck with new Prosumer 18mp camera kids, and keep an eye on EBay, all my lenses etc will be there soon.

LOL Sorry, you'll just have to learn to frame your shots properly to begin with, instead of relying on cropping a 50MP file. Or yes, you can switch to Nikon and work with 12MP out of spite LOLOL Priceless

I suspect macfly is referring to the rumored 36 MP D800.  If you do a little digging into macfly instead of bashing him (which I admit, I was guilty of in the past), you'll find he's a pro with an impressive portfolio, and often shoots with medium format bodies in addition to dSLRs.  He appears to have a real need for higher resolution for print ads (thus the MF cameras), and was clearly hoping for a higher MP body from Canon, from a professional perspective.

Having said that, for me, 18 MP is just fine...

I`ll second neuro`s comments... check out macfly`s website to know that his work is impressive and he would know the importance of resolution to his own work that I believe he has said before includes billboard ads.  Although brashly stated, macfly has a good point that some photography greatly benefits from higher resolution and I`m sure he stated in a previous post around a month ago that he is often forced to use Hassleblad MF and he dislikes that camera therefore was hoping and praying Canon will release a camera that can match.  Perhaps that was wishful thinking, a 35mm FF sensor may just not be able to come close enough to what a MF sensor can do.

Justin made some good points as well.   Although Canon is trying to state this camera is an all-around best choice, that`s just marketing BS... they may not believe for a second an 18MP FF sensor will work for high-end studio, fashion, landscape.  I think Justin is correct in saying Canon clearly designed this for photojournalists, sports, weddings, etc. where 18MP is enough and fast shutter speeds and low-light performance trumps everything.  Of course, not all sports shooters are going to love this camera... not enough pixels on subject for long-range shots so need to go up 1 in lens choice (e.g. 400mm instead of 300mm).  Another issue is the max sync speed is down to 1/250s which might bother outdoor shooters trying to overpower the sun with strobes... for example Dan Carr talks about his on his web-site.   Overall, as another member stated earlier today, don't forget Canon is in the business to sell cameras and they are building this camera for the possibly the biggest segment of pros... those working in the field (rough and wet conditions) who need fast shutter speed and low light performance.

Before macfly and others that have similar needs, waiting for the 5D3 before defecting to Nikon might pay off.  If they increase the resolution to 30MP,  improve the AF, and just slightly improve build quality (logical improvements to make), it might be a great studio camera... after all 5D2 did destroy 1Ds3 sales so Canon heard the money loud and clear... pros who would otherwise use the 1Ds3 went straight for the 5D2 clearly voting with their dollars that they can live without the rugged build quality of the 1 series.

Just for anyone that cares before the official press release is out and about, here's the PDF from the Japanese press release; it's where the AF image, GPS/Wireless images came from. Full specs are at the bottom.

This was taken down along with the press release, so it is official, it came from the Nikkei site.

Thanks.  Love your club photography by the way.  The 1DX should really work for you with the improved low-light performance!

The press release DID hit in Japan, but was quickly taken down. That's where the image came from, and the full detailed PDF with all the specs. So it IS official, Canon's just not ready to make it official yet.

Strange

Searching for "Canon" on Google News doesn't give any results for a credible news agency picking the story up.

Did the official press release happen yet (still don't see it updated on the USA canon newsroom)? If not, still holding out for a possible lens announcement too!

I don't think so.  www.canon.com/news/2011/index.html still only shows the "50 million EOS" news release that states the name of 1D X but no specs.

Hmmmm......

The 7D shoots 18 MP RAW files at 8 fps with dual Digic 4. If the Digic 5 is indeed 17 times faster and the 1D X has dual Digic 5 plus Digic 4 for metering, why can't it handle RAW at 14 fps? That's not even twice as fast at moving data as the 7D, unless it turns out to be foveon type sensor or something.

It's a good question.  To get the 14 fps the press release stated the mirror would stay up but still the sensor is being exposed at 14 fps and converting to jpg is additional processing after the RAW exposure and ADC so why not allow RAW at 14 fps with the mirror up?  The answer then could be that data throughput to memory is still the bottleneck?

Also, the press release didn't mention of how many frames at 12 fps the camera can capture before the buffer is full.

For networking, it looks like a LAN port with the option of wireless (with on-board bluetooth) and GPS adapters.

I like the idea of colour-based focus tracking with iTR (Intelligent Tracking and Recognition).


I like this translation  "Operation of the shutter unit cleared the test for 40 million times." now thats what i call durable :D


Pffttt...  That's only 33 days at 14fps, you call that durable?

If anyone complaining about the 'wired' ethernet wants to transmit 1 RAW file every 5 seconds over 54Mbps wireless, be my guest. I'll stick with the gigabit.

Considering studios already shoot tethered via USB, maybe they just decided gigabit was more ubiquitous and easier to implement than USB 3.

True.  And every computer (mostly) has ethernet (although perhaps not gigabit) while USB 3.0 has been slow to be adopted.
