Yes, it's already making me crazy and if I give the camera to someone else to take a photo, I'll have to teach them how to focus the camera. I just wasn't sure if that is close to the tolerance of the focus points.

Test it by using a plain bond paper with a dot in it. Check each af points if they will lock focus when the dot is inside the box. You can then explain to the techs thoroughly of the problem. That's if you decided to return your unit to them. But I suggest you send it back for another repair.

is this focus issue still present on new production models?

like ones manufactured within the last few weeks or months

Yup, Its has never stopped. Until canon admits there is a problem there is no chance of it getting fixed. And they are in full denial that there is anything wrong.

Hi everyone...

Just joined the forum. I just got my 70D about 3 weeks ago and was aware of the focusing issue when I bought it, but I liked the features so I thought I'd take a chance.

I'm just now getting around to testing it for the focus issue, but the only fast lens I have for testing is the 50mm 1.8. Out of 17 shots, I found 3 that were out of focus. However, I'm not sure if they're just user error. Two of the shots were trees and I'm not sure if this is to be expected when shooting through branches. I also don't know if the 50mm 1.8 is the best to be testing with.

What do you guys think? Any input would be appreciated. I'd like to just enjoy the camera and snap away.. but if there's something faulty, I'd like to exchange it while I can. Continue testing, exchange, or just ignore and enjoy the camera?

Pics are not showing. It will need to be known what AF point(s) and mode you are shooting in. Welcome to POTN.

I can't see your samples but three out of 17 OOF images with the 50mm f/1.8 is pretty good going, possibly bordering on record! Mine would give maybe 3 out of 17 in focus on a good day. Nothing to do with the camera though.

Strange.. I linked to the photos on dropbox.

Try these:

I just took screenshots of the two images side by side in DPP with the focus points showing.

Lefthand picture is center focus point through VF.. one shot mode. Righthand picture is live view.

As mentioned, 3 out of 17 OOF shots is a good ratio for keeper rates. But if you feel like investigating the camera deeper, try the tests made by some users in this thread, Maybe start with distant targets (enough to fill the mid point focusing square) and observe your keeper rates. Also, try posting them directly to the thread by getting a flicker account, upload and view the photo at flicker (maximum of 1024 resolution), copy the link location. On the message box of PotN, You will see an icon that looks like a mountain, click that and paste the link location and thats it. It will be much easier for the members to evaluate what you have. You also test the other af points if you feel like doing it. To my observations (just purely my assessment), I think the 70D (faulty ones) does not only have one issue. Mine has both the mid point and right af points defective and some only has the mid point problem. So I pray for your baby man, I hope you have a good copy. Welcome to the forum! :)

I had this on my first 7D.
Fundamentally the focus points were not where the boxes were. Fortunately I saw a Thread where someone had mapped the problem. Looks like they have this with the 70D or at least yours.
Eg at a wedding if one shot a line of people, and say picked the face of the person at the end of the line.
Ot would nail focus very quickly - BUT it could have missed that persons head and nailed focus on the wall 12 ft behind!
utterly useless! An iPhone 5S would be better!

I Sent it back...usual crap at first from the retailer. And just as much from many Togs who insinuated I just did not know how to work it,mornIncould try fixing it in Post!
Eventually they got me another one, which was spot on! lovely crisp images. So glad I did ... and then I loved the camera! :)
I think you would be insane to keep it. Just keep,pushing, until they get you a good one. Its not your fault canons QC is rubbish.

Replaced. Does this mean it can't be fixed at all?

Edit: Just ignore my queastion. I mis read your post. Sorry.

Thanks for the advice. I forgot all about flickr when I was uploading the files :o

I was thinking 3 out of 17 wasn't bad, but I don't know what everyone else was experiencing. I'll probably continue testing a bit and see how it goes.

Use this as your test.

Ok.. I ran through a bunch of tests using Toby's procedure. For the most part, when lighting was good, I see very little or no discernible difference between my viewfinder and live view shots when shooting charts and general objects/structures around the yard. I do see a difference when lighting is poor, but I assume that's par for the course.

Where I see the biggest difference is shooting leaves.. and I see it with the 50mm 1.8 as well as the 18-135mm kit lens at lower focal lengths. I'm wondering if there's just not enough contrast for AF to work and this just falls under user error?

Sorry for the silly questions, but I'm fairly new to DSLR's and trying to learn. If this is just typical behavior, then I'll give up on the testing and resume shooting.

Here are 3 examples:

I bought my 70D from Becextech, so any warranty is supposed to go through them. Camera came from Hong Kong. Bought it with 18-135 and 70-200 2.8 usm 2. Having the same focussing problems as many on the net. Been through micro adjust, bought FoCal Pro (that improved things somewhat, but I haven't been able to get far enough away from my PC to use it properly). That said, I really get the impression that the problem is random.

Just to be sure I've dropped it in at Canon in Melbourne to assess and calibrate before I send it back, if necessary, to Becextech.

I'll let you know how it goes in 10-15 days.

Update: Got the camera back from Canon a week ago but the problem remains I'm afraid. They advised adjusting some AF points and checking performance with both my supplied lenses. Further advised no other adjustments necessary - ie AFMA ( I guess) Have had a few reasonable pics that could be sharpened but an overall poor performance. Just written to Canon again with more samples.

Seems to focus a few degrees to the right or left of the focus point at close range - see sample .pdfs. I would have thought some AFMA was necessary but I'd be interested to see what readers think.

Thanks
Grant
