-Official- 1D MK III AF Thread. Firmware? Hardware Fix Is IN!!!

photoroebucks wrote in post #4064446
just got my markIII back from canon service center in cali
firmwire 1.1.0
FYI

Same Here!! Just received it back today and 1.10 still loaded. CA must not be in the 1.1.1 or 2 club.

They did set all my Cfn back to factory settings. I had to reset everything.

I'm in Albuquerque now. Let's see if the M3 can keep focus on those balloons at the 2007 Balloon Festival. I'm betting it can focus in on those big monsters. This year comes the brand new "Darth Vader" hot air balloon, all black, hmmm, a real test for it. Just checking in tonight to see if there was any news. What was the REAL last piece of actual news on this entire situation?

There has been absolutely no news/change/update of any kind officially or otherwise..... we just keep getting into trouble for posting non relevant info

BTW "Darth" looks Cool, better switch to MF though !

do you think the 50 1.2 is a good lens to judge the M3 by? It's notorious for front or back focusing...btw. this and your 24-70 that front (or back, I can't remember which) focuses, you might want to test the M3 with something you know focuses properly to see where it's really at.

I presume that cwphoto has tested the 50mm f1.2 on another camera body and it performed without issues. That leaves one of two options:

1. Either the other body is out
2. The Mark III body is out

Since other lenses have issues with his Mark III, I think it's safe to lay the blame on the Mark III

I have one suggestion to suggest. Set the lens to MF. Set the camera to show the AF point in red when it's in focus. Manually focus on the same subject, same lighting to see if the camera reports focus at some different point from when it is actually in focus. I'm not sure if someone has suggested that before. That will definitely tell me it's not the lens, but the AF modules/sensors/proces​sors in the camera itself.

Just another thought - is it worth while creating a thread/poll for Mark III users to indicate which lens or lenses are causing the issue? MIght not be a bad idea to try and collate the serial number/date of manufacture, to see if that's related to these issues.

Also, has anyone reported AF issues with the Mark III, with 3rd party lenses?

It's clearly front-focused by some margin...

I know this will not solve AF problems, but for a shot like that I would be checking focus manually anyway and overriding if needed. I have ordered two screens to help make manual focusing easier.

I'm with Kenny - One Shot is my biggest gripe.

I have it down to failing within two frames, here's the latest (focus on the eye):

IMG NOTICE: [NOT AN IMAGE URL, NOT RENDERED INLINE]

It's clearly front-focused by some margin (on God knows what though - there's nothing in the fore-ground which it could have accidently locked on).

I think it is worth starting a new thread for Single Shot focus issues. This is my problem as well, and I think Kenny and JB too.

CW, using the 50L wide open, you certainly have a razor thin DOF as this photo shows, but it also demonstrates -around the eyes - the same softness problem I'm having with my 35L and 24-70. Both of which have been to Jamesburg along with my Mk3 body for adjustment/calibration - with no improvement.

Thanks for chiming in Jeff. I'm thinking I'll contact Canon again next week and see what they say since we've not seen a firmware update nor any report on the Galbraith tests results.

Ok, I've opend a new thread for Single Shot issues here:

https://photography-on-the.net …php?p=4069641#p​ost4069641

We can take the discussion there and keep this thread clear.

Newbie member here. In my case the choice of lens didn't matter. All my L glass was suspect on the MKIII. However, my focus probs were intermittant. 5 out of 5 sequential shots would be fine and then the next 4 out of 5 would either be front or rear focused. Then the next 5 all would be fine.I couldn't trust it. Certainly not if some one was going to purchase the pictures. Finally tested on a tripod.
Traded bodies with my 1DsMKII and duplicated shots. No probs with any shots on any lenses. The s/n doesn't seem to correlate with the issues.
Mine is 52xxx and I've seen focus issues earlier and later than mine.
The intermittant problem may fool you. Keep testing in a variety of conditions. I had focus probs on both AI and single shot. High speed or low.
I use single focus point.
I shoot motorsports , athletics mostley and try my hand with art shots.
I sent my body to Canon twice. They reset my cf's so I had to redo them. I'm happy with the body now. I've run 3000+ shots now and all are fine under nite, high noon and rain.
The cleaner ISO is a plus.
Test often before your time is up.

Which service center? And what did the repair ticket say they did?

KAC

Well, that's very positive news mbeg - out of curiousity, do you have version 1.1.1 firmware on your unit?

And would you be willing to pass along your repair number for those of us that might want to take another crack at sending our bodies in? Its possible that the tech's could reference work done on successful repairs to duplicate the result.

Has anyone posted this. Sorry if I am repeating as I didn't see it!

RG was saying no improvement as of that date but note that he is impressed with how seriously Canon ai taking this issue!

The key to this is that RG tested a then 3 week old beta. I wouldn't put much stock in it, since the beta firmware was a test build given to shooters in Japan.

Although RG has been a major stickler and advocate, I think he might have caused more problems by posting a confusing statement on an old test build. He really didn't add much...If it was a solid fix Canon would have released it by the time RG posted those comments.
