I don't see it in live view or movie mode with my camera at 16:9.  The lighting or lens cap does not change it, just a black area at the top and bottom.  I wonder if some additional setting is involved.

The issue with SD cards is the extreme slow write time when overwriting previous data.  A regular in-Camera format of a card does not erase the card, but merely marks it as empty in the fat table.  Then, when you record a video, the card must first erase a block of memory before it can record to it.  This slows the write time to about 10mb/sec on many cards.
The 5D MK III offers a low level format option for your SD cards (not needed with CF cards) which completely erases the card, and allows 3 or even 4 times faster record speeds. This is a workaround, and Canon was obviously aware of the issue with slower cards.
This is why some have no issue and others run into problems.  I'd get the 95mb/sec card, it can erase blocks fast enough to allow recording over existing files.

Based on the feedback so far, it seems like the wear you are seeing is an extreme case. It's possible there was a manufacturing problem when they applied the finish on that part of your camera.
I have read of one other case like this, and I agree that there is some sort of issue with improper painting or they missed on the primer.
I'd ask Canon to replace the worn panels.

EOS Bodies / Re: Frimware on 7D version 7.7.7??

It occasionally happens that the technician did not restore the production firmware.  Just download the latest firmware and install it, or send it back to Canon.  They will arrange for shipping both ways.

Lenses / Re: 50mm upgrade or 85mm coverage?

All things considered, EF 85 f1.8 sounds like the best compromise.
+1.

I could not see any bars on my 5D MK III no matter what I tried.  I switched to 16:9 and other aspect ratios.
My first thought is that there might be some radio interferrence, so I held mine close to my Wifi transmitter, and did see a slight barber pole for just a instant, but could not get it again.
There may be some cameras that do this, I'd exchange it for another.

EOS Bodies / Re: 6D vs 5Diii vs 5Dii - Speedlite AF Focus Beam Assist Tests
« on: December 12, 2012, 10:35:54 AM »
How did you determine that focus was achieved?  I place the camera in 1 shot AF so that it will not fire until focus is achieved, and do a full button press.  The camera fires as soon as focus is achieved, which can be long before the AF indicator lights. 
So, are you measuring time for focus to be reached, or time for the AF indicator to light?

Thanks Mt Spokaine,  am I correct in saying that the black focus points (which my 5D has ) light up & indicate the point of focus by lighting up red to confirm focus (which is what the 5D & 580ex does) so is the issue that it is still the same system as the origional 5D ? or has something else changed that I'm not aware of. My appologies if you have already explained this & I'm not understanding.  At present at receptions & low light my method is to only use the center focus point which is assisted well by the IR beam.many thanks Peter
There is a short red flash which happens after the camera has achieved focus.  When using one shot focus, the camera will not open the shutter until focus is achieved.  My point is that focus is achieved well before the light flashes, and I always get a sharply focused image by just doing a full button press.
Note:  If You use AI servo focusing, the camera will fire as soon as you do a full button press, and you will get oof images.  This is user error, don't use AI servo in extreme low light.
Many of the issues that are posted about are the result of incorrect camera settings.

Software & Accessories / Re: What is the SD card speed required for 6d?
« on: December 12, 2012, 10:22:18 AM »
The maximum write speed is based on a totally erased (new) card. Formatting a card does not erase it unless its a low level format.   Then the card has to first erase a block of data before it can write to it, and for a SD  card, its SLOW.
The 6D, like the 5D MK III will probably have a low level format function for SD cards which will totally erase a card, but it will take a long time, maybe 20-30 minutes depending on card size, so its best done in a computer where you don't run your battery down.

Software & Accessories / Re: Yet another tripod thread...
« on: December 11, 2012, 11:21:33 PM »
A tripod needs to be high enough for you to see thru the camera viewfinder without cranking the center column up.  Thats where many tripods miss the boat.  Take the tripod height plus any additional head height, and allow two-three inches for the camera.  This should match the height to your eyes, and preferably be a little taller.  I'm 6ft 2, and a 67 inch tripod with a tall ball head works well.
 
If you are using the tripod for a telephoto lens, stability is critical, get one with a underhook and add weight to pull te legs into compression.  this really helps.  It also keeps your cheap tripod from blowing over in a wind gust and ruining a expensive camera and lens.

Lenses / Re: 50 1.4 on 5d3 anyone?
« on: December 11, 2012, 11:05:21 PM »
Getting some great responses here.  Now I also considered plunking down the cash for the 50L 1.2.  A wise choice?  Or does the price not justify the purchase over the 50 1.4?
What you get for the extra $$ is a lot more glass, better construction, and the ability to have super shallow depth of field.
You have to pay lots of $$$ to get even a tiny improvement.  Good used 50mm f/1.4's are available for $250, and are better on FF than the Sigma 50mm.  The Sigma is optimized for crop bodies and does very well there.

EOS Bodies / Re: black focus points on 5Dmkiii
« on: December 11, 2012, 10:58:17 PM »
Its a combination of the AF points being black and being tiny with thin lines.  The 7D is similar, but has large AF points with thick lines and its not a issue. There are some klutzy workarounds that light up the points briefly, but its probably the weakest issue the camera has, and it is only a issue in near darkness.

4213
I have no issue unless I wait for the red focus light to blink.  I just use 1-shot center point, and a full button press.  The camera focuses and captures the shot quickly.
If I wait for the red light to blink, it takes a long time.
There are some settings like spot AF which Canon warns about in the manual that make it difficult to AF, but just read the manual about those.
BTW, I do not see any difference in the time it takes for the AF light to blink if I use the AF assist light or do without.  In both cases, I've learned not to wait.

Reikan Focal has a option to save your camera settings and download them to your computer.  Do it before starting a AFMA.  That way, if the process fails, you can restore your camera settings.

Technical Support / Re: LP-E6 battery failure - Canon 6D
« on: December 11, 2012, 06:47:25 PM »
As Neuro noted, batteries self discharge, and can reach the point where the internal electronics will not let it take a charge.
Here is some information that applies to most all lithium ion batteries.
