Rob Gailbraith is excellent. His review will make a hardly used 1D Mark IV worth less than bellybutton lint would go for. Maybe I should get myself a cheap, used and utterly worthless 1D Mark IV now, instead of an expensive compact Ixus?

As the 1D Mark IV is useless for photography, I could let it be a fancy book-support in my bookshelf! :rolleyes:
Meanwhile, I can spend my time taming the 7D...

I have been using mk4 for good month and half by now. In this time I have been shooting about 20 alpine skiing World cup races, where skiers are A LOT faster then some speed skater. Next to that, you have pretty good chance, that you are standing somewhere on the hill, where you see skier just a split second before you need to take photo, so there's not much time to track them (opposite of speed skating, where you have huge amount of time, to track skater before you press shutter).
I was everything but happy with mk3. It was crap and shouldn't even be called camera. With mk4 on the other side, I'm quite happy. Sure there are out of focus photos. But they were also with mk1 and mk2. In general I would say there's less out of focus photos with mk4 then it was with mk2, and for most of them, it's operators error, not camera error (with mk3 it was camera error, and percentage of in focus photos was pretty much equal as percentage of out of focus shots with mk2 or mk4 is).
So to be honest, I don't care what Galbraith say this time. If it's working fine for me, I'm happy with it. And to be honest, I do get feeling from time to time, that there are some thing which we don't know behind all this. Is he all of a sudden just Nikon fanboy? I really doubt, but it wouldn't be so impossible. Is there some grunge between him and Canon? Maybe, and it's much more possible then him being fanboy. Does he get a lot more money from Nikon then from Canon, and this influence part of his results? Most likely. But I'm pretty sure, noone of us will never know real answers to these question. But personally I take his reports with a bit of safety margin.

Does anyone here know what the MkIII problem really was? Why it did/didn't do what the AF was supposed to.
I do.
Let's see if anyone else does shall we?
Post away.

that's not what happened. Phil was mad at canon because letsgodigital came out with a new canon before time and canon did nothing about it.
Then phil never tested the AF for any camera. For him the 10D was a good camera but the AF was never tested. It takes a little more than reading the press releases to perform some accurate testing of the AF like Galbraith did.

back to the 10D after months of users complaining about the jumping AF while the D100 was always spot on he added a note saying that there was a little of a problem , coming from reports of the users about the 10D AF engine.
that's admirable, also considering that he does the camera review thing for a living..

sorry but that had to be said.

The 10D was released in March of 2003. The 1D Mark III was released in April 2007. I'm not talking about the 10D release.

The incident I'm referring to was in 2007, and is why there is no 1D Mark III review on DPReview to this day.

Haha, you guys insecure much? He's just reviewing a camera, if you don't believe him or think he has a conflict of interest, don't read it or don't pay attention to it. This is a 6 page thread about RG, with little mention of the 1D MKIV's AF. I'm sure he wouldn't mind Canon sponsoring his site too, maybe he just couldn't work out a deal. Don't worry guys, I'm sure there will be people out there saying nice things about the MKIV soon enough. :lol:

I mean, to say that his review of the MKIII's AF was false/biased/unfair essentially discredits anyone who ever had an issue with it, and there were quite a few people who had problems with it. Sure, some people didn't have issues with it, but there certainly WERE issues with it, or Canon wouldn't have recalled the camera 3 times to try and fix it.

Finally. At least. Praise the Lord.

A pro who has been using and abusing his Mk IV (sorry if that sounds rude) in letting us all know how it fairs.

We should have a separate thread that contains posts like this and also from the Birders, etc.

I'm not saying don't put anything in there if someone has problems but it would give a better understanding of where this beast works best etc etc.

nah it doesn't have nuthing to do with the 10D, nor the 1DIII .. it was another canon camera that went on the letsgodigital site before time.

phil was upset (rightly) because canon acted like nuthing happened while he had to respect the non disclosure agreement while others could easily get away with it.

but there was another "incident" even before that, this time involving the canon site itself. and again Phil was right.
http://www.dpreview.co​m …/04081909canon_​eos20d.asp (external link)

so it goes back to quite some time (the canon affair LOL)

but again Phil never tested any AF. ever. and after Galbraith and his tests of the III lots of professional reviewers went well exposed for not testing anything and just read and report the press releases.

this is the second time I'm saying this and there won't be a third time.

It's mentioned here:

http://forums.dpreview​.com …30595&q=1DIII+r​eview&qf=m (external link)

And for those still discussing the 1DIII's lack of review - our failure to review it was nothing to do with any relationship between Phil and Canon, it was because dpreview was moving office, employing and training new staff, during one of the busiest periods of DSLR releases ever. Work was done on a 1DIII review (I've shot over 1000 would-be gallery images with it), but by the time we had an opportunity to review it, it'd been on the market for almost a year and everything likely to be said about it had already been said. That is the one and only reason.

... a long time... before any clear, concise and actionable responses appear, though... :cool:

And there are specific reasons for that.

So to be honest, I don't care what Galbraith say this time. If it's working fine for me, I'm happy with it.

As you will soon discover that, if R.G. is not happy, your happiness bears no relevance. Weirdo, isn't it? :D

And DO NOT even think of challenging the man's findings... or you will have a sheeps' stampede... coming right at you! :p

Imagine all those very happy, very excited 1D3 users out-there getting pretty much all the needed/wanted out of the camera, and working just fine for them...

No escape, then? :cool:

well I'm reviewing the 169 Basketball photos avail for download

10 images @ iso 200 strobbed AF tracking method: Main focus point priority
14 images @ iso 4000 AF tracking method: Main focus point priority
24 images @ iso 8000 AF tracking method: Main focus point priority
121 images @ iso 10000 still reviewing


I haven't reviewed them all yet but I have not seen one image that IMO has the camera set properly for multi person sport (eg. basketball)

every image so far as the

Auto focus / Drive AI Servo AF tracking method set to MAIN focus point priority

IMO - the camera should be set to

Continous AF track priority

IMO any discussion of the reviewers opinions and statistical results obtained with the camera set to Main focus point priority for multi person sports should include a disclaimer that maybe the camera was probably not set properly to obtain optimized images.
