p.35 #2 · RG on 1D Mk IV autofocus performance


Really laughing here ....although I haven't read all 28 pages of this thread....I did try to do my homework by searching on "Unique Photo" in the Canon Gear Forum and came up with zero hits! Hey at least I am making the best use out of my 28 posts in five years.

I do appreciate the award--probably should be a more prestigious award based on the duplicate posting/total user post ratio. I'm pretty certain that ratio is also somehow related to the poor performance of autofocus in the Mark IV.

p.35 #3 · RG on 1D Mk IV autofocus performance


And the bottom line (from the link):

So who wins the shootout? When it comes to high ISO, both cameras excel, but the Nikon D3S edges out the Canon. Autofocus performance is excellent on both cameras, with the Canon being slightly more responsive. Both of these cameras are professional tools designed to get the job done in the most challenging conditions, and they are both winners in that sense. The “Nikon vs. Canon” debate might never end among die-hard users, but the differences between these two cameras are more about user preference, and less about image quality and performance.

Canon "replies" to RG.

Happy shooting,

I don't like his constant reference to the sport he is shooting. Obviously, the sport is irrelevant and yet the way he talks you would think it is somehow important. I want to know what movement or actions cause it to miss, not what sport he is shooting at the time.

No, no, no, the Mk IV can tell whether you're pointing it at soccer or basketball, obviously!

RG noticed and has since added the same press release to his "analysis" pages.

After which RG offers nothing more than... ...silence.

I had a ball with the mk4 today. I will say that the weather was ideal, but some of the jerseys were not, but overall, no real issues. Just a bunch of sharp images like this one with my 300 2.8 IS and a 1.4x Canon.

I'll be posting a lot of galleries on my website in the

I guess this means that Canon designed the 1D-IV AF for lacrosse more than soccer

I was looking at the Speedskating sample images - after the first 10 or so images, wow that is terrible performance! Hard to argue against the sample images

I'm sure we haven't seen the last of this saga. We'll just have to be patient.

Happy shooting,
Yakim.

Oh for Pete's sake - of course it's not hard to argue against them - this thread has done just that from the start!

Wrong in-camera settings, user error, "hidden agenda", faulty camera - any of these (and possibly more than one) can explain those shots.

Then there's the stellar results just above your post and everywhere that flatly contradict RG.

Ok here's the problem I have - the stellar results posted are all clearly keepers, but any camera with a reasonably skilled operator is capable of at least some keepers. It isn't very difficult to find at least one in focus result from a sequence, and I'd imagine you'd be throwing the camera back in Canon's face if you couldn't get at least one in focus.

But have there been any complete sequences posted beyond a handful of photos that are contrary to RG's results?

Does anyone know how long RG has had a mark IV?

@ Dawei Ye

I had fun with the lacrosse action as I was regularly able to machine gun at 10fps and get whole a whole series in focus. I am back out shooting again today and hope to upload them to my website in a few days. I'll point you to the link so you can series after series that all in really good focus.

There are 2 sequences at this link.

Couple of days ago, some pro posted an article to refute Rob Galbraith's experience at photofocus here, but I can no longer assess it. Wonder if it's been taken down. Hmmm.... weird

So you didn't even read the accompanying text then?

I shot about 2000 lacrosse images today at a tournament. I have not processed all of them yet, but so far, I've only had to toss a handful due to focus issues. So far, about 1000 in focus and about 8 out.

I have read mixed reviews about the mk 4 but only excellent reviews of the D3s. Being a happy infocus owner of the mk3 the jump to 16mp would be a worthy upgrade but i will have to hire one before i buy. Canon has had inconsistent quality issues with individual cameras for a while now and even a large proportion of people i know buying L glass have had to return them for calibration. I do think Canon need to kick some butt in the R&D and quality departments.
