Canon EOS-1D X Digital Camera Body Details

[Humberto Ramos]

Canon made your 800 obsolete by disabling f/8 AF, the new 600 is now the longest lens plus the 1.4. I would sell today!!! :bg3:

looks like a simple 600 + 1DX rig will now sum up to 20 grand, hand holding it will be more fun for sure!

We can also buy a good car and a good pair of binoculars to watch wild life :bg3:

Not in the US, 20 grand will not buy you a "good" car that can actually go to places with wildlife...But it will but you a dozen of darned good binoculars. :w3

Occupy Canon!

ps: One of the suggestions I have been making for years is that the cameras be designed so that all sensors are available at f/8....

Wish they listened to you and made it so that center AF is possible at f/11. As the product has just been announced and is in public testing maybe you and the other Explorers of Light can really emphasize the need for f/8 focusing as that is one of the major draws of the 1-Series especially for advanced amateurs like myself.

Now it appears we can do two things to get AF at f/8
- tape trick
- LiveView AF

To me, Canon has managed to cut the sales of their Extender 2.0x III by a significant amount as lot of those who use TCs own f/4 and f/5.6 lenses. I sold my 2.0x II and I am thinking of not pursing purchase of the version III.

My wildlife car is a 1994 pickup truck, net original cost about zero. Regular maintenance & repairs as recommended by a good mechanic cost me about $1,000 annually, leaves more $$$ for photo equipment and travel. Safe, comfortable, reliable, unfortunately has no MP3 player.

The AF system suggests the 1D-X wasn't designed with birder input.

What's the millage like and how much you pay for gas

As a flight photographer I never use a 2X TC so for me the 1DX might indeed have the perfect AF system.

I don't think Canon deliberately drop the f/8 AF to annoy their customers.

The phase detecting AF becomes more difficult at smaller apertures, not because there is less light but due to the angle distribution of incident light. At f/8 the angle distribution is too narrow for precision phase-detect. 1DX uses new AF sensors and the split signal at f/8 is probably below its angular detection threshold.

see here for more info http://dougkerr.net/pumpkin/articles/Split_Prism.pdf

You can still use contrast detect AF in LV mode even at f/8.

We have to wait and see how the new AF system performs in the field.

FYI, Nikon also officially support AF at f/5.6 only, but they do not "disable" it at smaller apertures, they just don't guarantee reliable operation. I think Canon was paranoid with giving you something they were not fully confident in and having people complain to them later.

I have already let Canon know that if a software fix could solve the problem that that would be a very good plan.

Occupy Canon!

Good one, Arash! Occupy Nikon too, while we're at it!:eek3:

18 MPG with full camping/photography load, $3.58/gallon

Yup, best to see how it actually works, a few months from now.

At f/8 the angle distribution is too narrow for precision phase-detect. 1DX uses new AF sensors and the split signal at f/8 is probably below its angular detection threshold.

But Canon has demonstrated for years they have the technology to do excellent AF at f/8.

I do not mind the shift from 1.3x Frame to Full Frame but I wished they kept to the sensel size of 5.7µm (1D4) instead of 6.95µm (1DX). Not having a 1.3x Frame just means to me one more step in post and ore wiggle room to capture the subject.

BTW how many MP would a sensor with a sensel size of 5.7µm have?

 

[Roger Clark]

24*(1000/5.7) * 36*(1000/5.7) = 26.6 megapixels in a full frame sensor.

Thank you for the answer Roger. Are the specs to your liking?

 

[Jay Gould]

How many will move to the Dark Side if Canon doesn't correct this ridiculous decision before the release?

 

[Humberto Ramos]

I found a video on flickr, taken with an iphone 3gs, they say in they say the 1Dx was at 14fps, I count the numbers of shots taken in the LCD and it took 50 continuous shot's, but I dont beleave the buffer for jpg is only 50, maybe the 1Dx was at 12fps raw...50 raw at 12 fps is not bad...

Hi Pao,

No. I have a 1DIV and 5D2, which together are about the same price as the 1DX and have great performance. I see too many detriments in the 1DX over the 1DIV to upgrade for the imaging I do.

Bare 800mm

Canon made your 800 obsolete by disabling f/8 AF, the new 600 is now the longest lens plus the 1.4. I would sell today!!! :bg3:

looks like a simple 600 + 1DX rig will now sum up to 20 grand, hand holding it will be more fun for sure!

I personally would rather have my bare 800mm than a 600mm(840mm) with a 1.4tc . I will have to see for myself to believe that the focus speed and IQ is as good as the 800.
I do plan to sell my old 500 and get the new one because of the lower weight advantage though.

800 and new 500 is a great combo. But for folks who can own only one big lens the 600 is likely a better way to go.

Artie,

Can you ask the following question from Westfall

Exactly how professional photographers who do not shot group portraits can benefit from "face detection" ? Can it be disabled if it is causing trouble?

thanks

Arash, Here is Chuck Westfall's answer to your question: Face Detection tracking can can be turned off; it will not "otherwise screw things up."

Thanks, so when are you getting one? I can't wait to see the files.
