Lookin good at ISO 12800. Shows Decent DR at high ISO which might be one of the strengths of this camera.

Ok, the plot thickens...

When posting a screenshot in the AI Servo issue thread, showing that I apparently don't have that issue, I looked more closely at the EXIF window, and noticed it shows an AF Microadjustment of 2.  Now, I know I powered the camera off and on after applying that adjustment initially, and I also know it went to standby several times...based on the above, that should have zeroed out the AFMA values. 

When I first entered an AFMA in for my 40/2.8 pancake lens, I entered -2.  Right now, it shows 0 as described above.  If I go in and set it to +15, it shows +15 until I power it off, then 0 after powering it back on.  But...when I look at the EXIF in DPP for images shot at +15 before power cycling and 0 after power cycling, they all show an adjustment of -2, the value I entered initially.  The 70-200 II is doing the same thing - the values I initially entered (+3 wide and +2 tele) are applied to all the RAW images, regardless of the value showing on the camera.

So...it appears that either something changed after applying the AFMA values for the 40/2.8 and 70-200 II (the only lenses I've adjusted so far, which I did this past Friday morning), or the first AMFA value applied sticks, no matter what you do (including Clear All in the AFMA menu, which I tried earlier today). 

If the latter is the case (which I can verify by mounting a lens not previuosly used with the 1D X and applying an adjustment), it seems I have a strong incentive to get it right the first time...   :o
I'm happy that I held off on ordering one.  Its certainly a great camera, but there are a few things to work out, and I have three DSLR's that work perfectly now.
I will be interested in any Canon mirrorless, and planned to order one, but I'm beginning to wonder if thats a good idea.  All the camera manufacturers seem to be overwhelmed with issues in their new bodies.

$849 for a 50/1.4 II? No IS?

Just how stupid does Canon think we are?
Probably no more stupid than paying $450-500 for the sigma 50mm f/1.4.
Yes, prices are getting out of hand.

EOS Bodies - For Stills / Re: 1DX new all-time low-light king?

I've contacted a person that can compare 1Dx to 1Ds Mark III. What would be the best test scene to check performance of cameras in portrait photography?
I'd just view the comparison with the various cameras at the digital picture.  Bryan is very knowledgable and has a setup to compare many different Canon cameras with each other.
The link is a couple of articles above.

Chatted with B&H on the issue.  When inquiring about exchanging the camera, the response was: "Actually, it would be considered as a new order, since there are other orders in front of you, so it'd be the back of the queue...I can tell you that there are hundreds of backorders for this camera..."

On the bright side, he did indicate that, "We were also told by Canon that a firmware update should be released shortly to address this situation."
Amazing that all of the beta testers did not find this, since the first thing many of us do is to Microadjust the lenses.

I found this very amusing. Last time I checked the shutter button is on the right hand side. So a left-handed photographer uses his left hand to grab the camera either upside down or with the lens pointing to himself, then hands it over to his right hand for taking photos? Any left-handed photographer here to help explain the rationale behind this product?
I use one and am left handed.  The strap is designed to be reversed, so its no issue.  I use it over my left shoulder, so it hangs on my tight side.  I do hold the camera in my right hand, so its very natural. 
Most left handers are actually able to use their right hand, but no one person is quite the same.

If you were close, and it looks like it, the depth of field is very short at f/1.4.  Even at f/1.8, its not all that deep.
Thats the only issue.
For example, at 5 ft you will have a 3 inch depth of field.

My input is to buy a lens for a needed purpose.  You seem to have focal lenghts well covered, the 135mmL is wonderful, but doesn't fit what you say you do.
I'd consider a upgrade to your  body if you have no specific lens need, and the money needs to be spent.  A 5D MK II is a bargain right now at about $2,000, and fits your budget.  Otherwise, just sit tight and wait to see what other cameras and lenses are introduced this year.  The 24-70mm MK II looks like a huge improvement over the old lens, but wait and see.

The T4i is the first body to take advantage of the STM, but it works very well on all older models, but there are some additional things using them with a T4i brings.
Autofocus during video only applies to the T4i, and even then, its not a camcorder, its crude.  My D800 would autofocus during video as well, but it was really struggling.

EOS Bodies - For Stills / Re: Quality gap 5DIII?
« on: July 16, 2012, 10:58:17 PM »
I talked to our photographers. They took the still shots in one of our studios. With the same lens, using an professional lightning system or the aviable light (that did not change).
They will decide, whether they return all Cameras and make an switch back to Nikon, or they call for an "calibration" that every camera has the same quality. Before we bought the Camera, the representative of Canon spoke about an high quality, calibrated professional product. Afterwards they told us, that we have to accept an "little" gap of quality.
I´ll try to get an sample shot. The noise differs, like you take one shot with 400 ISO, the second one with 25000.... The worst MKIII produces noise, so @800 an black wall changes to an colorful pattern.
As I was one of the persons, that looking for that we buy Canon, I´m very disappointed.

In my opinion, its a shame, that Canon is not able to deliver cameras without  an quality gap for business customers.
The problem is that Nikon is just as bad, only it is like pulling teeth to get one fixed.
 
Sometimes you can't win.

EOS Bodies / Re: 1DX vs D4 sample
« on: July 16, 2012, 07:24:52 PM »
Is the wall white or gray?  Its easy to fool any DSLR when a lot of white is in the scene, you need to use spot AF to set the proper colors.  Otherwise, whites will be gray, and other colors off.

Good observation!  Actually the wall is grey and now that you ask the question, I must say the actual wall color is much closer to how the 1DX rendered them.  I do find the shadow part of the face on some of the 1DX to be too dark compared to the D4 however...
Only a serious photographrt has 17% gray card walls :)

Dropping users with the 10's of millions of EF-S lenses would more likely kill Canon. 
The APS-C / EF-s market makes up most of Canon's DSLR sales, and they are eating Nikon and Sony's lunch.
I love APS-H, but I do not see Canon killing off themselves purposely. If low cost FF cameras are actually coming out, our APS-H bodies may be the last of a 20 year run. (My Kodak DCS 460 from 1995).
APS-H was originally made due to lithography limitations, it was te largest senso size that could be made with one pass.  The restriction is lifted now, and 12 inch wafers are used instead of 8 in wafers to give better yield.
There really are no compelling reasons to keep churning them out.
I thought i offered compelling reasons. Lol
Maybe for you and me, but if you have a 10-22mm , 17-85mm ef-s, or 15-85mm ef-s, you might see it differently,  In fact, now that I think about it, I do have a 15-85mm ef-s for my 7D. i'm not worried though, their will be a adapter for the new Canon mirrorless.  (Now, there was a chance to use APS-H, but likely missed)

Lenses / Re: Canon 85 1.8 vs. Sigma 85 1.4
« on: July 16, 2012, 07:15:47 PM »
Having been bit by Sigma a few times, I am wary of any hype I hear.  This seems to apply to this lens as well.
http://www.the-digital-picture.com/Reviews/Sigma-85mm-f-1.4-EX-DG-HSM-Lens-Review.aspx
"As of Sigma 85mm f/1.4 EX DG HSM Lens review time, I have purchased (retail) three and returned two of these lenses. The first lens was consistently front focusing. The second lens was focusing so inconsistently that I wished for the first one back. The third lens is focusing very inconsistently, but does seem to average to the correct focus distance. I cut my losses and kept this copy of the lens "
 
"Roger at LensRentals.com is having the same problem - at review time, he has a warning posted on his Sigma 85mm f/1.4 EX DG HSM Lens rental page for this lens. "
"The big problem, as I already indicated, is that the lens does not focus accurately, consistently. Accurate focusing is especially important when shooting with the shallow DOF this lens is capable of. My experience with AI Servo focusing was even worse with a very low keeper rate for even moderately fast moving subjects. Over-shooting a scene gave me the one-shot AF results I wanted on most occasions."

EOS Bodies / Re: Possible issues with Sandisk Extreme Pro 32g CF
« on: July 16, 2012, 07:06:06 PM »
Let me tell you who is at fault, me. As much as i want to keep this to myself, i'll explain what happened. I named the two 32gig cards i bought so when i plug them into the computer i saw something like SanDisk 32g cf 1,SanDisk 32g cf 2. I thought since it is high end memory there wouldn't be issues. Wrong.
By the way it took a little more than a month and multiple times contacting them before i got the replacements, and interesting, they no longer have a gold stripe but a silver one on the CF. They are still extreme pro 32gig but silver. Either that indicates new ones are coming out and these older ones are silver or this is how they tell the new batch of cf cards with new memory...I don't know, just a guess.

Naming them might do it, Canon looks for their own name.  However, I've popped Nikon Cards into a Canon Camera and vice versa, and formatting merely renamed them to meet the Camera specs.
You can run a chkdisk on a card to see if it finds any bad sectors (Windows).  it will check every block, so it takes several minutes.  That does confirm the integrity of the card.
