I just read through the manual. Holly custom functions Batman! I look forward to the day when I shoot with a 1D body. I am curious how many 1D users have a separate CF card for saved camera settings. There are so many custom options, that one would really have to spend the time setting up the camera before each shoot. With the 1D series Canon makes sure that a photographer can get the most out of the camera. Very impressive and a bit intimidating!
There was one feature I was surprised to find missing, the ability to save movies to one storage media and stills to another. And I will confess to also being surprised by the lack of 7D-like movie and custom buttons, considering all the 1D4's features and customisation would benefit from such changes. Maybe 1D users would find the change distracting? It will be interesting to see what they do with the 1Ds4.

Did anyone notice the AE and FE microadjustments (C.Fn I-16 and 17)?
Each of them can be adjusted separately +-1 stop with 1/8 stop increments. No more complaints that "my camera systematically under/overexposes".
On the surprise side is that the RAW burst length is actually lower than with 1D III and for JPEG lower than 7D. Here are the values with largest resolution, highest fps and fastest card:
JPEG: 1D III 110, 1D IV 121, 7D 126
RAW only: 1D III 30, 1D IV 28, 7D 15
RAW+JPEG: 1D III 22, 1D IV 20, 7D 6
Though, naturally the amout of pixels in a burst is higher for the 1D IV than for 1D III. The RAW+JPEG burst size does not depend on the RAW resolution but "mRAW only" (9 Mpixel) ups the burst to 35.
Likewise, using M1 JPEG (12.4 Mpixels), you can get 164 frames in a burst and at M2 (8.4 Mpixels) already 309! Though, the 7D will give you 1122 frames at M JPEG (8 Mpixels)!!! That's a "movie" lasting over 2 minutes!

I guess we shouldn't be too disappointed, since the 50D's similar 15.1mp rez is rated for only 16 shots in a burst. As far as pixels pushed, it is equivalent to a 10mp sensor doing 45 in a burst. But, still, it would be nice to get another 10 or 20 shots (1 or 2 seconds) of burst. Canon has previously been conservative with these ratings. We really need to see what actual testing reveals. I'm definitely getting the fastest CF card I can find.

It will be awesome if all that had a real effect on a moving shot.
I agree. But, it is encouraging that the user doesn't have to rely entirely on Canon's decision about the balance of speed and reliability of tracking lock. The user can tweak it further by 5 levels of sensitivity (slow to fast), and also choosing priority of nearest or original subject. It looks like Canon left nothing to chance with this body's AF tracking. But, you are right. We need to see how it actually performs.

I can get 2-3 more shots in a burst with the 5D2 when I use an UDMA CF card. Similar with the 7D. So, I would guess that the 1D4 might have the same advantage. If you can empty the buffer quicker, the burst will last longer.

Interestingly, I just ran a test with my 50D with a Sandisk Ducati 8GB CF card and a 17-55 lens set to f/2.8 and ISO 100 and high speed continuous shooting mode, and I got 23 full speed shots before it started slowing down. That's 7 (44%) more burst shots than rated (16).

Remember the 1D IV now includes UDMA support, so for a similar buffer size as the 1D3 it should be far better as the files will get dumped to the cards faster, and it'll be far harder to fill up the buffer.

Canon states the burst size for both UDMA and non-UDMA cards. The numbers I reported above were for the UDMA card case (except for the 1D III).

Thanks so much for this thread. I'm #2 on the waiting list at one of the Canon Pro dealers in the UK so I'll be getting a MkIV in the first delivery. This will really help me get up to speed with it.

If some of you will be investing in UDMA CF cards for the first time, do yourself a favor and also get a UDMA card reader for the computer side! I use the SanDisk Firewire 800 UDMA CF reader and it is FAST! Sucks the 25MB+ files (5DMkII) off the UDMA card about 3 times faster than my old USB 2.0 CF reader! 45MB/sec vs. 17MB/sec. Same card, different readers. If I fill a 16GB card, that's typically about 600 images. So, let's call it 15GB. Old USB reader would take about 14.7 minutes to suck off those 300 files. The Firewire 800 UDMA reader does it in 5.5 minutes!
