I've got my 70D back,
Canon wrote as repair measures: Software update

They even didn't check the lenses! I have BF !

IMHO Canon don't know how to fix this issue.

I will make today some test pictures at daylight

The response from Canon may imply a possible firmware update.

Can you check the firmware version displayed in the menu on your returned camera and post it here?

This post confuses me. The Canon website (external link) does not list a firmware update for the 70D.

Azuma: I will post my MFA values tomorrow, i dont have my camera with me right now.

You made a comment in this post that you linked, that I want to respond to here:

You are doing a good test (focusing on a center object with detail in front and behind) to see if you are getting focus dead on, in front or behind where you want it. If the front surface of the left and right boxes are equal distant from the focus surface of the center box, I do not believe the front and rear boxes will be equally blurry. There is no EXIF info on the shot, so I cant's see the details of your test, but looking at a DOF calculator with the following parameters:
Camera: 7D, fl: 10', f/stop: f/2.8, focus distance: 10'

This shows the near and far distance.. I am not sure how "blurryness" is measured, but I pretty sure you would need to place the far object farther away to get equal bluryness.


my thoughts were that the DOF should cover front and back matches equally if I focus on middle matches, but my thoughts could be wrong of course :) .. front matches are certainly sharper after the calibration though.


i did some more tests with focus chart to confirm my previous test and it passed, i post them later.

i had problems only with my 50mm 1.8, which was still off on widest aperture after MFA:(

Im encountering this problem too... To my belief, it focuses inconsistently... here are some snap shots I made a while ago... Sorry for the very bad composition and grains, and the foot of course...

Details: 70d with ef 24 105 L, Mid-point used, f4, 1/50, iso 12800, Focused object is the white bishop. I know This shots were a torture but you can still identify the inconsistency of focusing. These were taken after clearing MFA...

Note: Even with tweaked MFA, same problem.

That's a pretty obvious problem. I've been following this thread and look forward to see the resolution.

yeah, as for now... I dont go for narrow dof... f6.3 shows consistency but again, sacrifices (bokeh) has to be made... I also calibrate at T+5.. It shows mprovements though but not quite...

Canon is going to have I come up with a resolution to this problem I would think. If you focused on the bishop, there are definitely major focusing problems imho.

Cant wait for azuma's post (as he mentioned) after Canon gave back his 70d... Hope they were(CANON) able to resolve the issue... Do you own the 70d too?

No, I was thinking of getting one on a couple months because of the live view focusing. But not until there is a resolution.

Ok, couple of issues I have with this post:

1. It doesn't fall into the parameters of the problem that the OP has described. The cross type sensor is not even activated in this instance (it needs f/2.8 or better).

2. I don't think it's reasonable to expect 100% consistent focus when shooting in poor lighting conditions. This is not a 6D with -3EV sensitive center point.

AF Points
19-point cross-type AF

All AF points are cross-type at f/5.6.

Center AF point is cross-type at f/2.8.

AF Working Range
Center AF Point: EV -0.5 to 18*

Other AF Points: EV 0 to EV 18*

* At room temperature and ISO 100, based on Canon's testing standards

Yeah I know and I respect your opinion, it may not fall on the OP's issues but it does have a relevance for me... Auto focus.

With regards to the consistency, could you please state an estimated rate of accuracy of the 70d? In my experience, this camera gives me at least 30 to 40% accuracy and Im starting to lose my confidence on it and to myself as well... Its a good a thing that I still have my 500d to regain my moral... Let me post two photos again... Shot by my 3yr old 500d and my 1 month old 70d...

I do really need your opinion for this... Photos are unedited.
Cheers...:)

Shot with 70d (f5.6, 1/160 iso 100)
