I am not sure about the 5D's AF but that of the Canon 1Ds MkIII's AF is more responsive with less hunting, if any, than that of the D700 under low lighting conditions. Besides that, the D700 is really an excellent camera. Speaking from experience here.... and we are not talking about lenses.

I just did the switch and for the cash I got I replaced:
5d
135f2
50f1.4
16-35f2.8mk1
100mmf2.8Macro
24-105F4IS
70-200F2.8IS
580EX
All I could get for the cash I sold my stuff for was:
d700
24-70f2.8
70-200f2.8VR
SB-900
so I lost 50f1.4, 100Macro, 135f2 and 16-35mk1.
I would have lost two anyway (16-35 and 50f1.4) if I would've upgraded to the 5dmk2 to cover the price so in effect I lost the 100M and 135f2 ~ $1500.
In exchange I got a much better 24-70mm zoom, a much better flash and 5 years of warranty on the lenses.
I consider the 5Dmk2 on par with the d700 depending on what you value (I preferred the d700 obviously ) so I don't include it in the calculation.
Ok, I think I decided to stick with Canon for now, sell one of my 5D bodies and the Sigma 70-200 ( which I was selling anyways, just picked up the canon IS version ) and get a 1Ds mark2 to see if that helps me out with the auto focus issues I am having.
Thanks for all the input guys, I greatly appreciate it!

Unfortunately the Mark II AF point layout has the same problem as the D700.
The Mark III system has been my favorite so far. All of the selectable points have cross-type sensors. Cross-types aren't the be-all-end-all of AF requirements, but for some shooting they're essential to get reliable focus.

This is exactly why I no longer own a 5D. I did enjoy the Canon 1DIIn AF but I would be concerned with the current 1-series given the 1DIII problems. You just can't go wrong with a D700 or D3 right now. Beyond IQ the AF speed, accuracy and overall handling really give Nikon the edge (for now - we all know how quickly that can change).

The D700 suffers some of the same problems as the 5D in the AF department, so I would highly recommend you try one out before you make the switch. The D700's AF is more flexible and "better" in a lot of conditions, but in one key aspect - the reliability of the off-center AF points in a wide variety of contrast situations - it's just as bad. The problem is that Nikon grouped the 15 cross-type AF points in a 3x5 array in the center of the AF spread. So if you're not using one of those points and the contrast you're focusing on is going the "wrong" way, you're hosed - just like you would be with a 5D.
Nikon needs to fix this issue before they can genuinely claim they're running with the big boys, imo.
FWIW, this is coming from a guy who just made the switch himself - most recently from a 1D Mark III (which I loved) and a 40D (which I hated)....Show more →
I find the D700 AF is in another league compared to the 5D. I've owned the D100, D2H, 1DIIn, 20D, 5D and D700. I rank the D700 AF equal of the 1DIIN (probably a bit better in all around performance if 3D tracking is in play) and on par with the D2H (although a bit better in some respects but nothing was as accurate as the D2H in my experience). The 5D was sluggish in comparison and never performed like pro-level AF.
I had a 5D for a few months and I have had my D700 for less than a week. There is no comparison for me...the D700 is just plain better. The only issue I have (and have always had) is trying to AF with things running at me (like my dogs!!) For some reason I can't seem to get a decent sharp shot no matter what I use (even had the same issue with my MkII's and MkIIn's)

Generally, I would agree. But sadly, as I pointed out in some particular aspects the D700's AF is still "not there", and many D2H users have noted that it was a step back in some ways. Whether you'd notice the issue I brought up really depends on how you shoot. If someone largely uses center point focusing or 3D focusing in the center area, they'll probably be very happy. But even users who only use AF-S will hit problems even in basic situations such as portraiture.

Never had one single problem with the AF on my MkII...or my original 1D or MkIIn or heck...my MkIII for that matter. But, this thread really is not about who has the better cross-type sensors now is it?

It's about someone who wanted to sell all of their equipment and buy completely new equipment, based partly on AF performance. I was pointing out that some of the 5D's problems are present in the D700. Are you trying to tell me that's somehow not relevant?
It's unsurprising that not everyone has experienced the issue I'm talking about - you need to shoot in particular situations to see it. And then again, there's those who loathe the 5D's system because it "doesn't work" and they don't know why - I submit that this is one of the reasons it doesn't work well. In contrast, even the 40D's system works better in the sorts of situations I'm talking about.

You are correct. You obviously know more about the similarities between the Nikon and Canon cameras AF systems. I just wish I knew about those "particular situations" you are referring to. Perhaps you can explain further so I can do some of my own testing with my D700 to see if the AF is as bad you say it is.
I had the same dilemma a few months ago... I shot with two 5D's and also felt severly limited by its AF. I sold my 5D's and got a 1Ds3. Never been happier.

The situations are low-contrast situations, or where the contrast is going the "wrong way". I tend to hit it most often when shooting portraits in portrait orientation. You can "work around" it by being aware of it and choosing your AF point very carefully but that can be difficult when working with kids, can lead to an unoptimal focus point, etc.
I also see it consistently in one shot I do often with my Dog Sports shooting where trying to focus on a jump doesn't work in portrait mode, but does in landscape (I only take this particular shot in portrait orientation, of course) when using the off-center points.
I have a little test I do in my office - focusing on my stainless steel coffee mug, the off-center points can't get a lock most of the time in landscape mode, but will nail it every time in portrait orientation (just an oddity of how the contrast is laid out). Same with the cross-type sensors - they work every time.
Of course, cross-type sensors aren't perfect either. You'll still encounter situations where they'll fail you - which is why manufacturers even have dual cross-type sensors. And of course the sensitivity of those sensors makes a difference as well - the D700 is slightly more sensitive in that regard.

That IS odd. Thank you for pointing out the AF irregularities. I never really noticed those oddities when alternating between landscape and portrait mode, but then again I don't alternate that much. You have given me some food for thought.
The D700 autofocus system is not bad. The 15 cross type sensors cover nearly the same area as 7 of the 9 sensors on the 5D. With the 5D your options in many cases are focus and recompose or crop to the desired composition because one of those 9 autofocus points is not where you need it. At least Nikon does give you 51 selectable points for focus. I do still have my D2H if I want to experience the goodness of Multi-CAM 2000 again.
I can make the D700 focus hunt all day and never lock with any lens by using an outside horizontal sensitive focusing point and trying to focus on something with just vertical contrast (like the edge of a light post or doorway).
The D700 system definitely is not bad. That's totally not what I'm saying. All I'm saying is that if you don't like the 5D's system, you may not like the D700's, depending on your problems with the 5D. I'm generally quite happy with the system and it is so much more flexible than the 5D Mark II's. Seeing that Canon was going to drag along the old 5D system is part of what drove me to Nikon - absolutely ridiculous.

You pointed out one of the reason's I did not stay with Canon and get the 5DMkII....the other is the measly 3.9fps. With the D700 I can get incredible high ISO performance and with the grip I can get 8fps. The decision was pretty easy for me.
as a portrait photographer I tend to use the upper cross type AF points of my 1Ds3 in portrait mode almost exclusively (to focus on the eyes). I get good results this way when shooting with telelenses up-close (6-9ft). More than 90% in focus shots. The 5D gave me 50% in focus shots under the same circumstances (on a good day). AI Servo with the 5D outer AF points gave me less than 10% in focus shots.
Right now I am looking for a smaller camera next to my 1Ds3. SInce the 5D2's AF hasn't much improved over the original 5D's AF (regarding outer AF point performance), I am hesistant to buy the 5D2. The 50D is no option either because I don't like its IQ (for my use it is basically a ISO400 cam).
So, I have been tempering with the thought of buying a Nikon D300 or D700 next to my 1Ds3. But if I understand you correctly, the AF of these cams would give me no better AF performance than the 5D(2) - in my particular situation - see above?
