Op (Alexandros), are you kidding me?

No, you are not the only one. I guess you haven't been following the dynamic range debate lately? ;)

Canon is known for banding (pattern noise) and now also underwhelming dynamic range. The 5D line has always had banding, and it seems that Canon doesn't know how to fix it, nor how to increase low ISO DR (at least not during the last 5 years).

Nikon on the other hand, are leaping forward with the sensor in their D800. Well, they are getting their sensors from Sony, but that doesn't really matter.

Canon needs to step up.

Please post your images showing the issue.  Show your D800 images as well.  I somehow am skeptical, having both bodies.
Here is one from my 5D MK II, notice the severe banding at the left --- wait, thats just a window shade.I at ISO 51200
 
And from my D800 at ISO 6400.  Both have a ton of NR.  Very grainy, and not much more detail that the 5D MK III at ISO 51200.

Site Information / Re: When are you usually on CR?

I seem to be online about 4-6 hours a day, early in the morning, after noon, and in the evening.  I'm retired, so I can spend a lot of time, but its usually in the winter or cold rainy weather that I spend the most time, in the summer, I am outdoors working a lot more

If you have to use plus 3 EV to see it, its not a issue.  It does depend a lot on the exposure, I usually expose raw images to the right, this allows you to pull down the exposure rather than boost it.
My 5D MK III was a little better in this regard, but you can still pull it up 5 EV and see the sensor.

EOS Bodies / Re: Brand new 5D3 has dust on sensor
« on: June 21, 2012, 12:58:39 PM »
Your camera sensor will have dust on it 1 sec after you clean it, so just blow it off, and don't worry about a few tiny specs.  As soon as you remove a lens, dust drifts in.
It is possible to blow dust around inside the mirror box with a blower, so get one like the gittos Rocket blower that is going to blow hard enough to blow the dust out of the mirror box.
If its nasty problem dust that can't be removed by blowing, then send it for cleaning, but remember, its always there, a little is something you learn to tolerate.

Tons of Aphids.  Our honeysuckle is still not open, but it will start today.  We have had cold and rain clear into the middle of June, so a sunny day is welcome. 
Hummingbirds have been scouring the vine picking aphids off, and have does a really good job, except for this bud, they somehow missed it.
I know you are not supposed to just walk around with a handheld macro lens to shoot tiny creatures using autofocus, but the 100mmL lets me get away with it occasionally, even if the images are not perfect.  The wind was blowing, so this was a bit difficult to get a sharp image, and it was in the shade, so I used a on camera flash rather than setting up a separate flash.

Lenses / Re: Canon EF-S 18-200MM IS slow to auto focus
« on: June 21, 2012, 12:05:48 PM »
I am finding my new EF-S 18-200mm IS lens quite slow to autofocus. Anyone else notice this or is it just me?
Quite slow is not a very descriptive term, does it tale 0.5 sec, 5 sec, or 5 minutes?  Are you focusing from mfd to infinity, or from 5 ft to10ft?  You could have a bad lens, or it could be normal.  We really can't tell, and assumptions are often wrong.
Comparing focus time with a lens like the 50mm f/1.4 will make the 50mm look fast, it does not move the internal mechanism nearly as much as iin the 18-200.

Haven't we had this poll many times?  It gets repetitive after the first dozen or so.

I love the packaging  8)

Yes, that's the first thing i told my friend too..it's NOT the usual white box..they made it classy!
Looks the almost same as my 1D MK IV except for the model number.  I have never had a new 1 series body come in a white box.

Did it do it just once, or many times?  Did it happen again if you changed memory cards?
My first thought is that it came accross a unwriteable memory block on your card and hung. 
 
If it works after the power reset, try the following:
First, transfer all the images to your computer,  then use a card reader (in Windows) run checkdisk with the scan for and attempt recovery of bad sectors box checked.  This checks every sector, even the empty ones.  If you find bad sectors on the card, its likely that the card was the issue.
After that, do a low level format, followed by a in-camera format.  The first test will find and report bad sectors, so it provides feedback to you without changing anything.
Note, a in camera format of a CF card does not check or map out bad memory blocks, it merely marks the fat table to tell the camera that the card is empty.  It might be months, weeks, or just seconds before the camera trys to write to the bad block again, and then it can hang.
It takes a while to scan all the sectors on a large card, so be patient, I just did it to a 16GB card, it took about 5 minutes.
I hope thats the issue, because its a simple fix.  Having a bad sector on solid state memory does not mean the card is dying, it does occasionally happen, but, if you check your card once a week and see it happinng again, then the card is dying.
 
If its not a bad card, you do not have too many other options.  To a total camera reset to return everything to its default status.  Sometimes switching to a non electronic lens like a Samyang has also caused me problems that were resolved by a full camera reset (this is a known issue).

Canon has never supported 64 bit, but i had to check and see if they were finally moving into the 21st century. A very large number of photographers use 64 bit, and while they can use third party solutions, Canon needs to step up.

Don't Argue with wickidwombat :)
 
Diprotodon, a relative of the modern wombat, was the largest marsupial that ever lived and had a pouch that was large enough to carry an adult human.

EOS Bodies - For Stills / Re: is my 5D3 faulty?

It looks like a image lit by ballast type fluorescent light taken at a fast shutter speed.  Fluorescents change color as well as brightness in synch with the power lines.
Electronic ballasts will not do this.
Try using 1/30 sec, and then 1/200 sec and compare several consecutive images.

I just use the center point, all the other points go unused.  Perhaps a option like you mentioned would convince me to start using other points.

The link takes me to a vote page, but how to view it wasn't clear.  I finally just went to the top page and paged thru the 50 semi-finalists.
 
I'm wondering why you just joined CR?  It appears that the main purpose of joining was self promotion. 
Consider becoming a active member, and our members will be able to learn from you.  You might also get a lot more votes in your future events.
At any rate, good luck, I hope you make it into the top 10, and from my quick view of your festival entry, it looks like you have a good chance.
