Unreliable AF on 7D with FW 2.0.3?
« on: October 12, 2012, 06:37:06 AM »
Hi all,

Before I bought the 7D, I had a 50D, and all my lenses focused perfectly with that camera body.

I recently updated the firmware on my 7D to 2.0.3. Was running 2.0 before (with no obvious issues).
Right away after updating I noticed that the AF had become very unreliable. It had a hard time locking and was hunting way more than before.

Especially with my f/1.4 lenses, a Sigma 85/1.4 and Canon 50/1.4, the AF is way off. The camera indicates that focus has been locked, but when I view the picture it is often very front focused. Sometimes though (about 10-20% of the time), the focus is spot on as it should be.
I also have a Canon 100/2.8 USM Macro and a Sigma 17-50/2.8 OS that show the same behaviour.

Actually, my only lenses that focus as they should right now are my Sigma 120-300/2.8 OS and Tokina 11-16/2.8.

I've tried using all the different AF-options, but nothing seems to help. I've reset the camera settings, done a hard reset, cleaned all connections between body and lenses.. Nothing has helped. It really seems like FW 2.0.3 is the bad guy here.

Has anyone else noticed this? It's driving me insane at the moment..

Haven't noticed that problem :o
Worked like a charm with 1.2.5 - 2.0.0 and now with 2.0.3.

I think you're on to something.  I'm having the exact same issues with all of my lenses.  I had actually thought it was the lenses as I purchases the 70-200 2.8 II and  Tamron 24-70 2.8 VC at roughly the same time I upgraded.  But I'm now seeing it with my trusty 24-105 and 50-500 as well.  Suddenly my images have gone to pot with focus.  As you mention, the camera claims it is locked on, but I can clearly see the image is not focused through the viewfinder.  Other times it appears focused through the viewfinder only to be out of focus on the larger computer screen.  It is a front-focusing issue.  I've tried micro-adjustments and such to no avail.  The problem does seem to be exacerbated by lower light.

"Good" to hear that I'm not the only one experiencing this.

As you mention, I've also noticed that the view through the viewfinder seems focused, but when viewing it on the LCD, or a computer screen, it clearly is out of focus. It's like the AF changes during the duration of the image being taken. Really wierd!

I've also tried micro-adjustments, but it hasn't helped at all, because it is different with different lenses, at different apertures, and at different distances.

I've seen this issues in bright daylight too btw.

Is there any way to make Canon aware of these issues? Do they have some kind of reporting system?
Next week I'll probably send my beloved 7D to Canon for service, and let them know exactly what I've said here.

I also upgraded to the new firmware 2.0.3.  The last few times I have been out shooting with 17-55 and 70-200mkII, I have noticed that the green focus light seems to stay on or comes on instantly after pressing shutter button without finding perfect focus.  Just noticed some portrait images were not sharp around the eyes, but thought it was user error.  Using "one shot and spot center focus point, no filter."

I am going out today to study this further.  I had not given the problems from yesterday a lot of thought until I saw this post.

It seems like we're having the same issue here. It happened to my 7D right after I upgraded to FW2.0. Before that, majority of my shots are spot on focus. After that, I would say a big percentage (maybe 20-30%) of my shots are out-of-focus. I have a 70-200 IS I, 24-70 Mk1, 50mm 1.4 and it is worst on the 24-70. I called Canon support about this issue and the rep said that the upgrade didn't include any FW update on the AF and I was even told that it could be something wrong how I use it. I said that is ridiculous since I'd been using the 7D for 2 years without any problems until now. Anyhow it didn't get resolved over the phone so I went to Canon Service Center in Irvine, CA and was told the same thing that AF is not affected by the FW upgrade and that they would service it for $219 since it's already out of warranty. I told the Canon desk support that it was perfectly fine before the upgrade. Nonetheless, nothing happened about that trip and I didn't budge in to pay for the $219 fee. I did some research on calibration and found Reikan Focal. I did the AFMA and it seems to have improved the AF. I could only say improved because I haven't got the chance to fully use the 7D exclusively on a shoot and conclude that AF is fine now, since I recently bought the 5D3 and haven't use the 7D that much.

I think Canon should take a look at this issue and not charge any fee. I spent $116 for the Focal that I shouldn't be spending at all if I hadn't upgraded the FW and the calibration didn't get messed up.

I believe someone mentioned in another thread that you can downgrade back to 1.2.5 firmware using an older version of the EOS utility 2.09 or 2.10.

Did you redo the AFMA?  Resetting everything like major new firmware might require it.  The fact that your lenses focused accurately on a different camera body does not mean that they do not need AFMA on the 7D.

As I mention in my initial post, they all worked fine on my 7D before the 2.0.3 update.

I've done AFMA using Reikan Focal, but it didn't help since this issue isn't there all the time.
It's like a glitch in the firmware..

No issue here, took 7d and 70-200 f2.8l to leuchars airshow after updating.  Over 1'000 shots. No probs.

Had problems prior to 1.2.3 where video files werre sometime screwed up, but worked well since.

As far as backdating,  add the "current"2.x.x firmware" and when it asks do you want to use this one switch out the file with a renamed 1.2.x.x.x  to a 2.fir   file name. the camera will swallow it and yo will even see in the camera menu update 2.0.0 with 1.25 yes let it run and you back in business.

sorry if this is glossed over but if you have played with DOS files or goofy thing like computers before you maybe familiar with it.

I have noticed different problem in my 7D after upgrading the F/W. The top LCD display displays the camera setting values even when I switch off the camera. It is sort of hung, power on/off do not have any effect. The only option is to remove the battery and reinsert it. This happens quite frequently say once in two or three days. Very annoying.

i do not have that kinda experience after updating new firmware 2.0.3.  however, i do not see the reason why new implementation/design affects auto focus when most of given updates do not relate to auto focus system, unless canon designs for 7d is in spaghetti implementation to start with :)
