Good luck jiggs
Fingers crossed for you man.

Thanks Scoob, I hope it gets fixed asap. A volcano (Mayon Volcano) in an adjacent province to mine is at breach of eruption right now. Burning rocks can already be seen at the crater and I cant wait to go there with my 70D. It erupts with every 7 to 10 years.

Update: Canon is doing great as for this time. I received a call this afternoon advising me that the focus assembly of my 70D are to be replaced with new ones. My hopes are getting stronger now but will still have to wait for the final output. This is only the 1st time I sent it in.

They're doing good on my part too. They exchange some parts and asked me to bring the lens that I'm having problems to calibrate them to the camera.
I have a great feeling that my camera is gonna be good this time.

I guess they already determined the issue. I did pointed the techs to this thread and I think it helped a lot as for their reference. Mine is sent back (from Canon main service center) to the branch I turned it in and I might be able to pick it up maybe tomorrow or Saturday. Feeling excited on this. :)

:( I was saddened by the result of the repair. It has the same issue. The af sensor was the only one replaced instead of the whole assembly. It's on its way back to Manila for another treatment.

@Centauro1974: If you can give Canon a call, do it now and ask what spare parts are to be replaced. Replacement of AF sensor alone would not fix the issue.

I don't understand this with Canon service. I am sure that most of us here articulate the problem to them very well when sending in equipment for checking and repair. Why do they send cameras back without checking that they have actually fixed the problems satisfactorily?

I have still to send my 70D back. I am so disappointed with it that I cannot even be bothered to use it atm esp when I see that Canon often do not fix the problem so you have to go through the cycle several times. I have gone back to the 600D for now. I should get my backside in gear but /shrug

I do not know about their QC but at least they are hospitable and kind enough in dealing with our frustrations. If not for them, I could have blown my temper after finding my unit unfixed. :confused:

Yes, I understand and I'm sorry you didn't get yours fixed this time :(

Like I said, I had high hopes for mine when I bought it and I'm so disappointed I can't even be bothered to send it in atm. I guess I'll get around to it.

Thanks Scoob, I sent an email addressed to the "EOS SPECIALIST" at Canon Service Center a while ago linking them directly to page 60 of this thread with post number #890. I hope that post could help me or them. I wonder whose post was that...;);)

Maybe for the second time around. So you still have your camera. I am just curious about this, Could you do me (or us) a favor? Could you try focusing a dot on a clean bond paper using AF points 13, 14 and 15 respectively? See if it will lock or not. Just make sure the dot doesn't exceed outside the square. Or you can try it out with a vertical line. Also check that the paper is clean enough that af will not lock in some areas aside from the dot. Just very curious on this.

Yes, I did all this a while ago and its not the focussing areas that are the problem is consistent front focussing outside the tolerances of MFC, so if I set the cam to -20 it makes no difference. At MFD my nifty fifty and Tamron 60mm F2 focuss a full two inches in front of the focus point as shown in DPP.

To see what I am experiencing, have a look earlier in this thread.

My thinking could be wrong but I guess some 70Ds have different kinds of issues. Mine has the mid point and right af points flaws.

I received the camera yesterday, the change the sensor, the mirror box and calibrate 3 lens to the camera. It seems to lock better with all focus points.
But something weird is happening now, when I focus using a single point, the focus is always outside on top of the little boxes. If I put the top left corner of the box on the part I'm focusing then it nails the focus, but if I put the box on the part that I want to focus it miss.
I don't know if this is normal, if I just have to keep on mind to move the focus points a little lower from where I want to get the focus.
You guys think it's OK to keep the camera like that or should I bring it back to the service center to readjust the focus.
Really confused.

Keeping it would be totally up to you. Personally I would send it back with a note saying the focus point in DPP do not line up with the focus points through the viewfinder.

But if it doesnt bother you or feel you could get used to it by all means keep it. It would drive me crazy and would make it much harder to resell.
