The latest report on 1D Mark III AF issues

http://www.robgalbrait​h.com …_page.asp?cid=7​-8740-9006

Looks like it's true.


**EDIT** August 5th 2007 CDS
At this point in time, 6 weeks after this initial post, we are no longer excepting suggestions for CF settings as a solution
to a broken MkIII.
Please post MkIII settings in the MkIII Settings thread found in the MkIII Sticky at the top of the forum.
We appreciate your intentions, but all of the recommended settings offered by Canon and half dozen pro photogs have been covered numerous times in this thread.

Thank you

Excellent. I received mine 3 hours ago. Nothing like a feel good story like this to kick off the ownership experience.

However, I will let my own results decide. Not to take away from the article, but i need mroe of a sampling from owners on here before i buy into one particular experiment and opinion. Of course, they could be correct in that article.

Those burst sequences are better than anything I've ever gotten with my 1 series bodies. And yes, I had a 1d Mk.II at one point.

I don't see a comparision to the Mk.II, just saying it did better historically. Ask the girl to go back to the start and pick up the comparision body.

To profess using a/the scientific process, one must use it.

I still find it hard to beleive that an army of testers and engineers at Canon are trumped by someone shooting a day of track.

The army of testers and engineers at Canon were also trumped by the first schmoe to get a 20D lockup due to a loose-fitting 20D grip It is unfortunate that he didn't do a more controlled test, but he's not the only one of his crew shooting with the Mark III, and I'm sure they contributed their own experiences. This will start a huge firestorm of controversy, and I don't think Rob Galbraith is the type to throw himself into that if he weren't absolutely certain there's a problem. The fact that the problems are limited to bright daylight is encouraging--a simple firmware tweak might do the trick to fix it.

Start? Are you kidding? This has been going on for weeks already.

How about "exacerbate" then? I know lots of bird photogs in particular have been raising cane over this, but Rob Galbraith isn't just some random dude talking trash on the Internet about how the 1DIII sucks. His credibility won't be cause for skepticism, although his unscientific testing might.

well i ordered one a couple of hour's ago after reading many many view's from the people that have it .
Tanking all that into account i came to the concluion that the camera is ok and there might be a few that do indeed have a fault - but you get that with car's conputer's TV's and everthing else thats made .

The rob galbraith story above is not what i had hoped for and when i get the camera around 2 month's i was told , i will give it a proper test from the word go and it can go back if it carn't match my mk2.

thats exactly what i planning on doing. i will test the mkIII in my usual shooting spots and style and if i see that it doesn't match the performance of my mkII, it will go back to the store and i will pick up a new mkIIn and a new little lens as a compansation for my trouble

These initial problems are exactly why I am waiting to purchase this camera. I'm using a 5D and my old 20D right now for all jobs but can't wait to own the Mark III like the rest of ya! Are these issues with Mark III happening on all bodies?

Its all very odd Some are happy with it some are saying once they have talored the settings to there need's it will be ok.
rg has tested 4 now and not happy with any of them YET he was testing it on what should be a very easy target, a runner even the 30d/400d would do that well.
all are very happy with the IQ and noise level.

Assuming there *is* a real problem with the AF system, could it be solved with a firmware update?

This is great news for some of us that have the early release. I have been trying to figure out what I am doing wrong or what settings I need to change to get good sharp images. I shot with it yesterday at a baseball game and I experienced the same problems soft focus on many of the shots when it was bright and hot. When it turned to nigh,t and I was shooting at high ISO and getting enough light without going to flash I was loving it. It is a great camera in that retrospect and my images were a lot better then the day time shots.

This past weekend we were shooting at a tournament with bright sun and temperatures at 100 deg F and the camera was not working well. I just assumed that it was me and not knowing what settings needed to be used for the application. However my son was not having the same problem with the IIn.

So now what do I do. Send it back and try to get it fixed. Sounds like that is not an option at this time. Can I return it and get a refund and wait until they get all the bugs worked out then get another one? I will get another IIn in the meantime.

I hope they get it fixed before night football. This will be a great camera for that application.

only Canon would know that but even if they can it would make me wonder if they slowed down AF to make it more accrate - if that was the case the mk2 would still be king.

It looks like in all those examples in the article were using large lenses. I know we all want a perfect camera but we can't expect all lenses to work exactly the same with one camera. I think everybody should get their own conclusion and I don't think the AF issue will show in every camera.

I thought I was just a dumby that I couldn't dial this Marklll in for surf shooting, yes I have gotten some of the best exposures ever with the Mark lll, but, the consitancy in AI Servo is sub par...with my Marklln I had at least 95% or better focused shots (in other words it was a non issue)...with the Mark lll its maybe 50%...I can't live with 50/50 with my shots, hopfully Canon is paying attention and will fix this Camera so it can be used for what it was designed for....Sports shooting which normally occurs on Bright Sunny Days.......with a super telephoto lens, in AI Servo as fast as possible and in focus...
