70D focus issue & blurred pictures

My 70D is effected tested it on a few lenses and then the lenses on a 5D and my old 350D, focus is great on the other cameras, inconsistent on the 70D. Found myself using my manual focus lenses with live view more and more. Fine in the studio but no way is this acceptable out of there. If I wanted to use a focusing 'live view' screen I'd have bought a mirror less camera.

In for repair now, so I'll know in two weeks if Canon Ireland have fixed it, if not it's refund time. I'm not in a position to be messing around with sending it back and forth.

A camera that won't focus is no good to a photographer.

No argument there...

And that example just posted is not a case of too close and hitting MFD, correct?

Good point Team Speed it looks like that alright, I'll dig out a few others that better show the issue.

Here's a better [worse] one of the problem, the camera point is on his cheek the focus is on his top. Other ones are closer to being in focus some are back focusing
Taken on the 4 of April 2014, Canon 70D, 1/800 ISO320 Canon EF 50mm f/1.4 USM @ f/1.4 and that lens was just serviced by CPS.

It was my understanding the focus issue was at a distance of 17+ feet. Unless I missed something, wouldn't the closer shots be more a matter of front/back focusing issues which could/should be corrected with mfa?

The camera can front & back focus at random so no matter what mfa you dial in, it's out for the next batch of missed shots & that's really annoying. The 5D never [OK, rarely] misses & shooting the kids today with my old 350D gave nice sharp shots [for the 350D's 8mp resolution].
Needless to say I'll be testing it again when cps gets it back to me. More scientifically this time using a tripod and chart to map the differences in focus over a few days of shots.

Canon have a great camera in the 70D, I really hope they can get this issue sorted out.

I see. Well, unfortunately until Canon even admits that there is an issue, a fix won't be forthcoming anytime soon, I'm afraid. I don't have the problem with mine, but I do feel for the rest of you, and the fact that so many are experiencing a problem which Canon won't admit to...yet.

Convinced that this issue was isolated and not common for North America - I headed to local BestBuy (Toronto, Canada) to purchase a copy of 70D with 062XX series (one guy few pages back also have problem with 062XX series)

I went outside and took picture of a large signs in good lighting condition using the centre focus point (Sigma 17-55MM F2.8) and here's the results:

Using OFV (Optical ViewFinder) - Focusing on word CINEPLEX

I suppose the result is not too difficult to discern. The OFV picture reveal of any magnification on a computer screen would reveal that the picture was not in focus. Unfortunately, I've tried to do numerous tests after (Focus chart and my friend as model) and it all came back soft for the most part. This is beyond MFA adjustment question as only some of the focus points in the camera did not function (for my copy, adjacent left, top and bottom focus point perform much better than the centre and adjacent right)

Personally, I love 70D build quality, menu layout, touch screen, swivel screen and really want to keep this camera. Unfortunately, I'm left with no option but to return it for now.

Does anyone have a 058xx 70D series? How it performs?

is this issue a software issue or does canon need to do a physical hardware adjustment to repair this issue,when efected cameras come back what was the diagnosis and was the prob solved,i got my 70d online and i haven't tested it yet as I'm working away and i don't have it with me,will canon be able to provide a software update that will fix the issue that everyone can download even if u don't have the issue.

Can you give the EXIF information for both photos? It's not in the image so it could even be an user error?

I have yet to see one come back fixed. The 2 that I have seen come back the paperwork references making an electronic adjustment to the center focus point. Neither were fixed, they were sent back to the customer as still broken unit but adjusted the best they could get.
Mine is due back next week so we shall see, but I am not holding out much hope that it will be fixed.

Whats being refereed to here is NOT an MFA problem or something that can be fixed by MFA.
The focus on affected 70D's is all over the place. Sometimes its front focusing other times its back focusing. I bought Teamspeeds focus tool and it worked great to show what the problem is. I did 4 straight MFA adjustment test. While NOTHING changed f1.4, ISO 100, Shutter 1250 camera on tripod, mirror lock up, 2 second delay and remote trigger. On 4 back to back test the mfa best setting was +4, +9, -3 and -1. What would the MFa be set on to cure that focusing issue?
Same lens 4 back to back test @ f4 +7, +7,+7, +8. But setting the lens to a MFA of +7 and shooting @ 1.4 rarely will you get a shot in focus.

This test was repeated with a 85 1.8 and a tamron 28-75 2.8 with almost identical types of results.

Yes, its about MFA, It think he has the same case with Two Hot Shoe. What I intend to show is how the 70ds are dealt by Canon when the units are turned in. Different findings by the techs with one thing in common, units are returned to the owners at the same state (defective). Very annoying.

Hello everyone, sorry for bad english.

I have similar problems with my 70d, mostly with sigma 18-50 2.8-4.5. It was purchased by greek store, but propably German import as there was not greek language printed manual.

Just take a look in this greek forum I posted samples,

http://www.dpgr.gr …8.msg771270;top​icseen#new

first 3 with center point at "epson" logo. No problem with nearby af points as shown next. At 18mm, f2.8, 1/200, OS on, handheld me sit on chair, target distance about 50cm. It does not hapen if target is very bright and with great contrast.

Also have Tamron 28-75, canon 40mm stm, only sporadic problems with them, not something i can reproduce constantly but just a feeling that AF is not always very sharp as it should.

Will sent it to canon service tomorrow, glad to give any add. info or try some shots till then.
