I don't have either, but a photography tips blog I subscribe to did a comparison of the Mk2 & Mk3.

100L Macro on a fast moving subject (raw file 100% crop, no edits, and full frame inset)....

The AF is slow in the macro range, unsurprisingly, but at conventional non-macro distances it seems swift enough.
Just picked up a 5dmkii and 24-105 on here tonight from the classifieds...

Thought I would say hello to everyone.....

On my 5D2, using centre AF point, with a subject at ~3.5m distance the 100L comes into focus subjectively at least as fast (faster, I think) than my 70-200/2.8L IS MK 1 set to 100mm whether focusing from infinity back down to 3.5m or from 1m (1.4m for the zoom) back up to 3.5m. If the focus is already close to correct then confirmation is pretty much instant. Otherwise it's maybe 0.5 seconds to snap into sharp focus from further away. That's indoors with lighting from a single fluorescent strip light in the kitchen.
Obviously there is more glass to shift in the big zoom lens, so it's not a complete surprise that the little macro lens matches or beats it at that sort of shooting distance.

many thanks for the explanation. so AI servo with all spots enabled works like Nikon's 3D tracking, difference is that it doesn't show the red dot. I had an entry level Nikon and with 11 AF points, 3D tracking was pretty much useless.For AI Servo to be successful with all points active you must always start focusing with the centre AF point over the subject. The camera makes the assumption that the centre point is where your subject is to begin with. If the centre point is not covering the subject when you begin to AF then your results will be highly unpredictable and probably disappointing. This is different behaviour from using all AF points in One Shot mode.
If your subject is large enough to cover more than two AF points at once and can be clearly identified (by the camera) from the surroundings/background then theory says that the other AF points should take over if the subject moves away from the centre point. However, if your subject is small - e.g. BIF - then it can easily slip between AF points, making all points Servo AF fairly hit and miss. Equally, if the subject blends into the surroundings the camera may not be able to tell that it has moved and will not know that it needs to change AF points in order to track it.
Very nice!
I think you could have taken her photo with my kids vtech kidizoom and she'd still have looked good though!![]()

I've experienced the same with a couple of lenses, initial disappointment then they end up being used most of the time.

Well I have taken delivery of my 5D mk2 and I have to say....I'm very disappointed!!!
I don't know why but I just am, the funny thing is, it's the same feeling I had when I got my 1D so I know my feelings will change because I now love my 1D.....strange dont you think ???
and they recommend that you just need to get out and spend some quality time together, get to know each other, take some shots with it etc.
Wondering if I need a spare battery if this would suit....not prepared to spend silly money on a canon original...
That depends entirely on how you shoot and your access to a charger. I've had my 5D2 and 7D for just over three years and I've yet to find the need for a spare battery. The same is equally true of my 40D, 50D, 1D3 and 5D3. So long as I can charge overnight I've yet to run out of power during a day's shooting, which might typically top out at around 1,000 frames on any one body, but is usually far less.
If you shoot a lot of video or use Live View extensively it might be a different story, but for "normal" shooting you'd have to be going some to exhaust a fully charged battery.
The only time I've bought additional batteries was when I had a 30D and grip.

Anyway, I've rung NHS Direct for youand they recommend that you just need to get out and spend some quality time together, get to know each other, take some shots with it etc.
If this doesn't work, you might have to consider putting it up for adoption![]()
One from today with 5D2 and 100L Macro wide open, no edits. AF on static targets was much snappier in bright light than when I tried indoors with fluorescent kitchen lighting - pretty much instant.
