Try the Canon D30 or D60 (not 30D or 60D), and you will know what slow AF means.

Todd: I did not follow your comment "and I never looked through the viewfinder once."

How did you even frame the photos if you did not look through the viewfinder?

I held the camera at my belly button, and tried to follow the action without looking through the camera.

I used all AF points in servo to start then switched to center AF, center AF was better, but not that much better.

since I was so close, I wanted a lower angle and also the kids with 8th grade so I was taller than most of them too.

This doesn't prove anything.. it would be so easy to replicate these focus issues it's not even funny. Back button focus, release button, move camera backwards, take picture. Or just mess up the MA.

User error when using back button focus could also be the issue.

I don't think anyone said the 5D's cannot focus, it's just that they could focus a lot better. I'm quite positive Canon will correct this with the next model.

There's little point in pretending that someone claims the 5DII simply can't focus at all and then pointing to in-focus photographs to demonstrate that it can. I don't know of anyone who's said the 5DII simply can't focus. Most people who have owned the camera (and I'm one) would say the center point is quite good but the outer focus points are inconsistent. Not that every photograph made with outer focus points is bad, just that it's something of a guessing game as to whether a photograph made with them will be in focus or not. And some of us think that for $2,500 or so the 5DII should do a better job than it does when using the outer focus points.

the thin DOF with an 85mm 1.2 or a 50 f1.0 would give you crappy results like this if you wernt paying attention to the DOF. and your distance from subject...


No, if your focusing point is closer to MFD as you say, then the fingers (which are even closer) should never be in focus. It has nothing to do with DOF.

It depends. Like always. :-)
I do Weddings since 4 years now again. If you do a docu you run around and look for a motive. Does really anybody on this world use anything else than the center AF point? No. That is why wedding shooters do not have big issues about the 5D (& MK II) You just can not look for the placement of any AF point and fix it or switch to it before the important moment has gone. There are three possible ways to handle: 1. Trust one and rearange, 2. focus manual or 3. trust your camera that it will find the focus by using its great 45 or whatever AF points.

You might guess what comes out. 1 or 2. Solution 3 gives you 10-15 % of keepers if you want to compose a beautiful image. Because no camera knows anything about composition. It will choose one or a collection of AF points. If it hits what you want, its just one thing. Luck! One can switch between not eye focused AF points if one trusts them. But that needs TIME that you do not have if you want to catch a moment. At least 1-2 seconds (if you are really fit with your gear. That is about 1-2 seconds to long for catching an important moment. Nobody waits for you. I shoot 600-1200 pictures at a wedding. My customer gets about 250 - 300. Whatz do you think why? Because the rest is deleted.

I don't have any hard numbers either. It was just a comparison between those bodies. But if you get way more. Then you probably get more than 100% That's really good.
So why don't you buy a 1 series if you get that much more keepers? Instead of using a camera that you don't like!! Even the older low prices 1 series bodies that are really cheap, have nearly as good AF as the new. You really must like to torture yourself


I've got a 1DsmkIII and 1DmkIII, so I have no idea what you're going on about.

It's pretty clear, as soon as you see a quote like that, that the person making the quote hasn't used a 1-series (or any body with a decent AF with a good spread of AF points) for any extended period of time.

I use my centre AF point less than 10 per cent of the time, I would say. "Focus-recompose" is pretty useless when shooting at 1.2.

Ralph, I like your photographic style, but this doesn't really make sense to me? Why in the world would you prefer to focus bang in the middle of the frame when you with, say 45-51 AF points, have the freedom to quickly shift focus to exactly where you want it? Pretend that someone at a wedding reception is saying something funny and everybody is looking at that person smiling. Wouldn't you prefer to compose your frame so that persons face is placed close too the rule of thirds but still bang is focus?

Yes I would. And I would do it faster in center AF and recompose, than in any other manual way. The laugh would have gone before I would switch the focus point with scroll wheel or joystick. Only other ways I can imagine it would work are manual focusing anyway or ECF.

For the original poster:

It's the outer points that people moan about on the 5D.

The autofocus system on the 5D MK II is the same as on the 20D.
So Canon took a very old and very cheap system and put it on reasonably expensive camera.
That's what people moan about.

Yes, you can take a good image with a 5D MK II.
You can also take a good image with a shoe box and a pinhole if you have enough skill.
This isn't the issue.

Thee 20D did not have six assist points around cross type center point as the 5D/5D II has
so 5D's obviously not simply the 20D focus

The 20D did not have six assist points around cross type center point as the 5D/5D II has so 5D's obviously not simply the 20D focus

The 20D did not have the feature below (nor does any other Canon camera, except the 50D): From Canon 5D white paper:

Additionally, the center AF pointís f5.6-sensitive, horizontal line-sensitive sensors each have two lines with individual pixels arranged in a zigzag pattern, making a total of four lines for horizontal line-sensitive focusing at the center. With this improvement, the center AF point can now do a better job of detecting difficult-to-read, low contrast subjects, thus improving the overall performance of the auto-focusing system.

Some people have claimed that 5DII has a better center focus point than 7D. The description above explains why.

The 5DII also has a color temperature sensing capability, that no other camera before it had, in relation to pulsed AC light (i.e fluorescent lighting). The 20D did not have this color sensing capability.
