7D Mark II - Focus Discussions

Looks like the 70D Focus issues thread all over... hello 115 pages.

I remember when I saw somewhere a thread of the first photo samples for the 7D II with some lenses on the net
I said at that time : isn't that a soft photo from the 85 f/1.2L lens ?
it seems the same issue of some copies like the 70D

Pages 135-136 of the manual, you can adjust for multiple copies of many lenses. Some the Camera can pick up the serial, for others you can enter it manually or just make one up. Only lenses that have an * in the lens info serial number area are limited to adjusting for any copy of a given model.

Well this is interesting. My page 135-136 talks about Flexizone AF. Note: I believe the manual leaves a lot to be desired.

The issue is not a consistent miss, the issue initially reported is that it would vary between shots - if you take 5 shots, and all are front focused by the same amount, you do not have the problem, you just need to use MFA to adjust the lens to the body. If you take 5 shots and one of them is on focus, the next one is back focused, the one after that is front focused, etc, then you have the problem.

The Tammy 150-600 seems to be having a lot of users reporting focus calibration issues with the 7D2, which is somewhat interesting.

I just did a bunch of tests against a focus target on a tripod and I get very consistent results with my 17-55 and 70-300L. I would also ask that as people are testing try other points around the center point and see if it changes much.

I have a Tamron 150-600mm and I am getting the 7D2 early next year. Can you tell me how many tamron 150-600mm/7D2 users have this problem front/back focusing or can you provide a link where I can see them? Thanks I appreciate it.

More likely a bad batch problem. The AF units' batch may have been bad. Also there may have been a programming error.

Could you define "ok" on the 24-105? Having one lens work and not the others sounds strange. I would expect none or all to be honest with the possible exception of ultra wide lenses since AF seems to be less important due to the expansion of the scene.

The 24-105 had more pictures in focus - about 70% compared to 10% on other lenses with the 7D2

There are two manuals. The printed version that come with the camera is the short version. The full manual is on one of the discs as a PDF file. It is a shame that a printed version of the full manual is not included with the camera.

Thanks. I new something wasn't right. The manual that came with the camera is seriously lacking. I guess it's for those that just wants to just snap a picture. I will download the pdf version now. Shysters.

What are your release/focus priority settings?

Most reputable companies have an exchange
Return period. I have returned my 7d mk2 because of
Focusing issues and should get my replacement
Today.
Hopefully the new body will work fine if not
I will return it and wait until the focus issues
Are fixed.

You have to be careful with individual company policies. Some will accept a return but will not refund your money if you decide you don't want the product. They offer in store credit only so you are stuck with buying something else from them. There aren't very many out there but they are out there.

I would guess that the 24-105 and the camera are pretty close to matching for focus. Contact your vendor about the issue and see if they will exchange. I suspect they will when they have stock to do so.

It allows you to determine whether focus is the priority or if shutter release is the priority.

If focus is the priority, the camera won't allow you to shoot until it's in focus.

If shutter release is the priority, the camera will fire whether in focus or not.

Choose wisely.

One of the disks? Mine only came with one disk. I just checked the "in the box" tab at B&H and it only shows one disk.

Yes, I know that. That is why I was asking nsnqst what his settings were to eliminate shutter release before focus was achieved as the source of the problem.

Great question Ian.

The real manual (full PDF from Canon's website) not that abbreviated joke they ship in the box
