7D Mark II - Focus Discussions

So you're saying that a more advanced system takes longer to acquire focus? Seems kinda backwards..

People have had luck letting the tracking settle in. I personally find it unusual. I have a theory that there is something funky in the firmware that doesn't shut off the Af adjust, eat signal when shutter releases. It would explain those cases where nothing at all is in focus, yet has fast enough ss and Is is off.

Interesting..what is eat signal? Tell me more about AF adjust please. Please excuse the internet if I sound sarcastic, it's not meant that way...

BTW: compariosn images. The first is the 7DII, second is 5D3. Same settings in camera, all manual. I think these speak volumes:

Yeah, that picture is just totally oof. Not sure how long you can play around with it, my call is to return it and move on. I would give Canon a lot of credit if they publicly realized a problem and came up with a solution. Instead, they are pretending the problem doesn't exist, denying problems and or replacement in many cases. They're making people live without their $2000 or camera for months on end. Not sure what their end game is, but I'm sure they could potentially lose customers over this. I'll tell you what, if it weren't for the investment in lenses that most people have, many would have jumped ship already. Canon really needs to get their act together.
Now, I realize that a certain percentage of people may be using the camera incorrectly. But there is also a number of people that have been through multiple copies with no positive conclusion. My guess is if you went through 4-5 copies and still
cannot get sharp focus, it starts to reveal a systemic problem. The same goes with he 70d. The cries haven't been as loud from those owners, and my only fear is that they aren't as experienced. Then on top of all this, there are other forum members suggesting to not return the body for a refund, but to send it in to canon for repair. This, I don't get at all. Canon seems to be releasing new models too soon without enough field testing.

Maybe there is a batch of serial numbers which are faulty? Perhaps a list of faulty 7D MK2 serials would help identify which ones need replaced/recalled ?

Well Canon have already lost a sale, I was thinking about upgrading from my 7D, but I feel there are just far too many people many who have tried multiple copies, that there is definitely a problem with this model, so I've decided not to bother and just stick with my 7D.

If Canon doesn't sort this pretty sharpish it stands to lose a lot of customers. You expect honesty from a manufacturer of their calibre.

I agree, and actually meant to mention this. Most companies, once they get enough flack, release some sort of serial #range and recall the units, fix them and everyone is satisfied. Canon seems very reluctant to do this now and in the last past. I follow all these new threads because They are the threads which point me to my next piece of equipment. The new bodies I'm reading about are telling me to stay away, far away. Customers ought to just return these and have all these shops send them all back to canon in bulk so they're forced to resolve the issue at their own expense. But yes, a recall is necessary. I just feel that if owners don't know what is causing this af issue, how can they ever feel comfortable with one of these bodies? Is it something that is just bad in the manufacturing process or something that just slowly goes out of spec from use? (Poor parts etc)

Same here; until we know what's going on with the 70D/ 7D2 I'm staying away from both. Sadly, that probably means I should stay away from the T6s as well. It seems like it could be a great value, depending on the ISO performance of that sensor, but not until I'm confident they've solved whatever difficulty they have with that 19-pt AF sensor. Weird that it's been dead reliable in the 7Dc.

Ah well, the 5D3 calls.

What are the EXIF values for those images?

Wow that is OOF. My buddy who shoots with ef500mm mk2 told me that he was also getting OOF shots but he was able to dialed in after tweaking the camera default camera setting but I really don't know what he did and he ended up keeping his and that was his first copy.

I think part of the key is the AF tracking. I've found better success leaving it at the case setting rather than dialing it down. When this camera locks, it locks hard and is difficult to adjust, which is both like and unlike my 1Dx which locks hard, but can be adjusted if you miss focus. With my 7d2, results are better not dialing it down to help with tracking, but putting the pressure on yourself to do it right. I've also found the earlier you can lock on and start tracking, the better off you'll be.

My tuppence worth.

Day 1 with camera and 100-400ii straight out the box, rushed out to shoot with this new, focus on anything uber sports/wildlfe god in the making. Got home, 90% crud.
Day 2 spent MA
Day 3 day in the field 50% crud.
Day 4 day in the field 20% crud

Almost all of the crud after dialling in are attributable (sadly) to technique. As I am adjusting to the way this camera works and likes to be worked, I can only see the crud factor dropping further.

I'm not sure we are at the recall stage yet.

Dummy me, not sure I understand what you mean by "dialing it down". Care to elaborate ?

Just got off the phone with canon and after discussing the focusing system, they said I had a very good understanding of how it works and everything seemed set up perfectly. I sent in 4 images and they said it definitely seems to be a camera issue!!!! Shipping back to B&H today. What a bummer...tried everything I could to make this camera work. If the AF system could just work it would be an amazing camera....oh well not trying my luck with another body as I've seen to many others on their 3 & 4th, just don't have that kind of time....Very sad
