Where was the point of focus? Looks like in the foreground?

I presume you are talking about my "Red Dirt" shot. A single spot on the trunk of the tree at f11 with a 28-135 at 28mm. 1/5 sec exposure.

Taking your advice, here's one from tonight. An Oklahoma roadside photo. I've been concerned about my 7d2 because I've read so many bad reports, but I think mine is good. I am used to seeing some color fringing around tree branches against the sky with my 50D. The 7D2 seems to do much less of that.

Nice shot. I like the colours.

Maybe my imagination, but the bushes in the foreground look more in focus than the tree. Hard to tell on the compressed picture though.

Hard to tell at 100%. I did test the camera during this shot as Canon suggests by focusing in live view and then re-focus in the viewfinder. The lens did not move so I guess the f11 DOF, the somewhat wide lens setting and the fine grass make it hard to tell. The fine tree branches also seem quite sharp to me.

Well, I started this thread so might as well add an update. As originally stated I've been out shooting or should I say looking for something to take a picture of. Along the way I played with the MFA settings and I think I am as far as I can go.

These two pictures are at 200mm: full view and 100% crop

Now, how to post more than 2 images? Will follow-up with the second images. All images are with the tamron 150-600 at F7.1 and ISO 400 on an overcast day. Range on these 2 probably 75-100 feet.

OK. The next two pictures are at 500mm: full view and 100% crop. This one is not quite as sharp at 100%. MFA issue or handheld at 500mm - not sure. IMO it will definitely do. I know, not great subject matter but hey, it tells me what I needed to know.

Looks like, at least in my case, for the tamron the final verdict is an MFA of +2 on the wide end and +5 on the long end. Anyone with suggestions as to final tweaks, I am all ears.

After shooting a wedding the other day, I have to say that under exposure will really take away from how sharp a photo appears. Certainly still usable, but for those looking for the very best image quality, then nailing exposure does seem to be the key. I've seen several 'this isn't sharp enough' posts, and one common denominator seems to be underexposure - JMHO. Not talking about the ones where the af seems to be misbehaving. The other thing I found was exposure with my 430exII flash on top is exceptional in ettl - I've never had a camera do better at making a flash look, well, less flashy. (evaluative mode).

Thanks Randy. Glad you liked it. It was in far NW Oklahoma City near Piedmont on Memorial Rd west of Sara Rd.

Some thoughts on the supposed focus issue with the 7D MkII.

After reading the several threads on this forum about focus problems with the new 7D MkII, I was very concerned about mine so I've done a good deal of checking and have come to the conclusion that it's mostly a lot of noise about very little. I have no doubt that there are a few defective cameras out but the threads here make it sound like most of them are bad. I've searched for reports other than on POTN and found almost nothing. I think there is a sort of "hypochondria" that comes from reading too many bad reports.

A little MFA has helped mine. I did not use dot tune (which I did with my 50D) because I read reports of erratic results with Dot Tune. I tried photographing a target next to a slanted ruler at Canon's suggested distance and found very little wrong. Then I looked for some "real world" MFA subjects at various middle distances where back and front focus were obvious. My camera back-focused my 28-135 a bit and I have adjusted it. My 100 Macro seems to be dead on as is my 10-22. I have a few other lenses to tweak but I am confident that any focus problems will be found and corrected.

Exposure, as ksbal has said, is important. And camera or subject movement is also important.

Too much pixel peeping will make one crazy! Always keep what you see in context and try not to be too influenced by what you have read. I have run side by side tests with my 50D (a solid performer that I trust) and my 7d2. The 7d2 results are better - always.

Some folks will just complain and some people's judgement is colored by their frustration that Canon didn't put a Sony sensor in the camera. "Some people don't have much food on their table but they got a lot of forks and knives and they gotta cut somethin" " Bob Dylan, 1961. I certainly don't mean to doubt those who have had defective cameras, just to, hopefully, put things in perspective; I suspect a large percentage of 7D2s are just fine and I'm going to just go and enjoy mine.

Heh heh, well stated, and I think you are right.

These pernicious posts have me scrutinizing my 7D2 shots looking for the out-of-focus effects. Look for blurriness and you will find it, but I don't think it's the camera's fault.

Very well stated and true as in any release. The ones some of us are talking about are huntersdad who is an experienced 1DX user got 8 keepers out of 400. Another member who's is on it's way back from Canon which replaced the AF assembly. Another experienced shooter FM who sent it back. I had the same experience as huntersdad did on a sunny day but wish I had 8 keepers. They were not just out, they were awful. My first BIF outing with my 7D in 2009 a few days after ownership produced about a 95% keeper rate.

Unfortunately it does get people concerned and they should look at their images and it they are happy then great. Everybody has their own perception of what looks good to them.

I did comment on an image from another site that was not presented very well. Maybe I should not have which I did say during that discussion.

It is just like the Olympus OM-D E-M1 EVF burn issue that has plagued me from the beginning.
https://photography-on-the.net …showthread.php?​p=17335380
From reading the forums, one would think it is happening to everyone, but that is obviously not the case. In fact, there seem to be so few cases world wide that Olympus isn't even going to try and find a fix for it for this model, and will simply keep replacing the TFTs. Cheaper. So the two questions to ask are:
How many cases are there compared to the total units sold?
How many owners are even members of forums such as this one compared to the total units sold?

Naturally people here are sensitized to any issues that might arise because they are interested, or they got hold of a lemon and are looking for advice and/or assistance, or they are, as in my case, simply very cautious buyers. I want to make sure it will work for what I want and need before I buy one. If all I see are fuzzy pictures, then up goes the red flag. But when I do see pictures that really do look like what I am looking for, then I think, OK, lets give it a go. If he can do it, so can I. Like these: https://www.flickr.com​/photos/mallardg500/ (external link)

But in the end, I would guess we are a TINY fraction of the total 7DII owners or potential buyers. But that is the way it is these days. Life on the internet....;-)a

As I've said before there doesn't seem to be any issues with my copy. With Christmas around the corner I will, for the first time since I received my camera, be able to spend more than a couple of hours here and there trying it out. At least as long as the forecast doesn't change for the worse. A couple of days off with sunshine will be a real treat. Something to take a picture would also be nice. Keeping my fingers crossed.
