A new camera has a 1 year warranty, send it to Canon for repairs.

UPDATE- Got my new 7Dii in today. Issue is resolved and I was able to complete my tests this afternoon, Ill let you guys know when the shootout vs the NX-1 is finished. Turns out there are many others who are having this issue: http://photography-on-the.net/forum/showthread.php?t=1406704&page=64, there is a guy in there who also had 2 bad 7Dii bodies, I do believe we will hear more about it in the future, and yes, perhaps a tutorial on how to troubleshoot it, MFA, etc is in order.

While most of you seem quite knowledgeable and helpful (Jrista is a good example), there are others who use their obvious intellectual gifts to belittle & ridicule others. Sometimes cameras don't work the way they should, and just because they don't it doesn't mean the photographer is always to blame, doesn't know how to use a camera, did it intentionally or you should assume the worst about that person.

I know many of you do not like what I do with my tests, and that is fine. I am not as smart as many of you, but I will use what I do know and learn about to help and inform those who might sincerely be seeking it.

I have done hundreds of test shots. For the record, I have also owned the 40D, 7D and 70D and did not see the same issue.

Maybe my eyes and brain both need MFA  :o

The Canon 7Dii isn't a beginners camera? Thats funny. I hear this a lot, never made any sense. Its like saying that someone who can afford a 7Dii isn't allowed to buy one unless they can prove they are a pro. Beginning photographers will buy the best camera they personally can afford, not necessarily the cheapest one. There is no connection between experience level and what they can afford.

I admit, I am surprised how many of you believe that MFA is part of the normal Canon experience. I love Canon, but I know when something isn't working right.

MFA is for specific tweaking under certain circumstances, not to get the camera to focus correctly out of the box and it is absolutely not something Canon recommends to all of its camera owners, as many on this thread have advocated.

From Canon about MFA and the expectation of acceptable tolerance: http://www.learn.usa.canon.com/app/pdfs/quickguides/CDLC_Accurate_EOS_AF_QuickGuide.pdf

I wasn't actually asking for help, I was trying to offer some information about my personal experience with the 7Dii's focusing issues, in case anyone else was having the same problem and once I find out what is going on, that information might be helpful to them.

So let me get this straight, in your minds, it is completely acceptable for a brand new Canon user, to open his $1800 camera and expect to know how to MFA a camera, or even know what it is for that matter?

As a long-time Canon user, I have never had to MFA any the Nikons Ive tested (nor Canons), nor would ever do so with any brand new camera for testing because that MFA would not be the same experience new camera owners would have out of the box. Probably something you didn't think of. 

So what do you guys do for a living? Just curious.

So background info, I do a lot of head-to-head camera testing for my youtube channel, Ive done this many, many times, most recently with my 5Diii vs D750, no issues. My main lens is a 24-70 2.8 v2, but I have a V1, and my Dad has a V1 as well. Ran into issues with both BRAND NEW out of the box 7Dii's.

Yes MFA is disabled. Shooting on AI Servo, Single Square, Full High Speed Burst- 10 FPS, Av mode at 2.8, shutter speeds are usually over 1/1000, sometimes all the way up to 1/8000 depending on light. Like I said, this isn't new to me.

Results on the 7Dii's looked as per the image posted, almost all of them, unless the subject is very close. I also did a side-to-side test, both cameras missed nearly all of them.

Tonight I thought it might be the v2 lens, so I grabbed mine and my Dads v1 (24-70 2.8 v1), his 70d and my old 7D. For some tests.

Both 7Dii's consistently missed with all three lenses.

The v2 and my Dad's v1 works GREAT on my 7D and sufficiently good on the 70D, though there were some misses.

If the V2 is working on other cameras, and not any of my 7Diis, Im coming to the conclusion there could be some focusing problems with the 7Dii itself. Maybe not all of them, but the 7D whopped both of them tonight in terms of focusing accuracy with the same lenses they were using.

Ill have to return both of them and I am hoping their replacements will be better.

Just my opinion, if someone spends $1800 on a camera, it should be working right out of the box.

The requirement to have to Micro Adjust a Brand new body, to me, seems crazy.

Ill keep you guys posted, should have the next body in on Tuesday or Wednesday.

Turning off MFA when shooting at a ruler seemed to correct focusing with very wide apertures on a non-moving subject.

So this morning, I went out to redo my servo sports test, with a different BRAND NEW Canon 7Dii, same lens 24-70 2.8 (which I know is working on my 5Diii).

More soft focusing.

Im upset about this, thats 2 Canon 7Dii Bodies in a row. Ill have access to two more later this week. Ive taken a couple thousand shots with 2 different 7Diis, about 90% or so are no good.

This is what it looks like:

I have an update on my "soft focus" 7Dii.

Turns out that if you have your AFMA turned on, even if all the settings are at "0", it can mess up your cameras focusing. I had mine turned on, with no settings adjusted and it was missing focus, turned it off, and it appears to have resolved the issue.

I will do some sports testing tonight to confirm, but in my tests here at the house it appears to be corrected.

jrista- I have the DR test shots of the NX-1 and 7Dii with the new ND filter set up we discussed, about 15.3 stops of DR. Whats the best way to send them to you? I like what you did on your analysis and I think these files are the ones you wanted.

I ran into the focusing problem today with the Canon 7Dii during my Servo Testing. It is consistently focusing behind the subject, nearly all of it's side to side test shots were out of focus. The 5Diii as a control had no issues with the same lens.

I am looking to send it back for a swap out. Ill update if the replacement is better.

Ill definitely re-do it in the future, I just won't be able to do it right away. It has been a helpful discussion and scrutiny is what makes these tests better. You guys are really the only ones who are trying to help me with this, so I do appreciate it and I am listening.

I should have expressed it more along the lines of "how can you accurately measure up to 14-15 stops of DR with a 13.7 Dr test strip", and while I have repeatedly agreed with everyone that it would be idea to overexpose that first step, with a larger DR strip, they do not exist. We can't seem to get past that point.

In any event, I think I we might be on the same page with the ND filter over part of the existing strip. That way we can get the first part dialed in, and still have enough headroom on the dark end to measure into the 14-15Ev range.

Right, but it isn't 13.7, it is 13.3 (if we are overexposing the first step) and we actually agree that more real estate is needed.

I would love to test the A7s on S-log, well past the 13 Ev mark.

Then we are going to have to respectfully disagree. If the precision your require is as outline, you cannot measure anything over 13.3 DR with a just a 13.3Ev strip. I would be happy to buy you an ND strip if you believe you can work it out.

I can see you are putting a lot of analysis into this and I really appreciate it. We agree on many points about the utilization of the wedge, but I actually think there are several ways to use it (not just one) and possibly even better tests that will come from it. Right now I am leaning towards putting a 4 stop ND filter infront of it, which technically then could get us a strip in the 17 Stop range.

Additionally, what you are suggesting to overexpose the first step and only that first step on all cameras, as well as all channels is going to be just about impossible, and would make the test less quick and easy and more of a headache.

My mind still isn't reconciled that what I am doing is incorrect for comparison between two cameras shooting on the same settings, so we might disagree there too and that is ok.

I think the results are easily visible and speak for themselves and I am still open to any feedback you or others have and definitely do not want my gratitude to be misinterpreted.

My last post directed at Domino Dude. Not you Jrista.   8) you know it might be easier for you to get a wedge and try it out, they are only $14.
