Frustrated

[Don Kuykendall_RIP]

That is a lot of info to sort through in that post. I have the 150-600mm C version. On atleast half the shots I used 1/1600 with the same result as the one I chose thatwas 1/1250.
I just remembered later last night that between the zooshoot and the shots yesterday of the Osprey that I did the latest firmwareupdate on the lens. It stopped in themiddle of the first attempt but the second time it completed with noerrors. I plan to check it later todaywith another camera.

I checked the lens using the FoCal at the distance suggested during lots of reading but that was a while ago and am not sure what length I used. I think 50. Which happens to be as long as I can go inside.

Then do what I had to do set it outside so you can see it from your computer setup.

I bought a D7000 a year and a half ago and have been battling the AF with it the entire time.

I immediately have 2 questions with this:
1) Are the expectations realistic?
2) Batteling compared to what?

Example I do not get the results I expected with the D7000 on AF level, one of my main reasons to go to DSLR in 2013.
I improved my technique (sometimes I need an other camera then the D7000 to get the shutter speed I want) and compare to my D70S and A7S, the D7000 AF is the best I have. Do not forget sometimes in hot weather it is simply not possible to do long distance shots.

The AF was better but nothing to write home about. I have just been living with it. I would guess I get 3 out of 10 pictures that are sharp semi-sharp at 100% view.

100% view is not what you see a lot of others, it is challenging => is it realistic?
3/10 seems OK for most of the work I do, obviously better is possible, but a lot more effort and investment might be needed

I am thinking about getting the D 7200 but am concerned the AF on the 7000 series may all be crap. I might rent it before to see how it does. I also am considering the D 500 but the double price I am not sure will give me that much more for my money depending on if the D 7200 actually can focus unlike the D 7000.

Renting seems a good idea, compare sees how it works for you.

I have a D60 that is 7-8 years old that focuses better than the D 7000.

This seems a good statement, as it compares. Show it in a controlled test.
Some stated the fact that the D60 captures less information, means it shows less the issues you might have (lens and technique).

Looking at the pictures, is it me?

Controlled testing should show. Do not take it too serious, but do different set-ups with a test subject that is controlled.
Avoiding distance at first, camera shake, photographer shake, etc... auto vs manual focus (lens sharpness).

I come with results that people do not believe as well e.g. the 70-200mm f2.8 VRII is not that good according to me. It is the best, but the margin is lower then I expected and sometimes I come with better results with lesser lenses.

Many have posted in the past on the focus issue on the D7000, which seems trolling mostly. It is not perfect, but it can perform.

Vincent,

Lots of great info and thanks for the time it took to respond. One big one you mentioned is the heat. I did not realize it could cause focus problems. Of all the reading I have done about focusing I have never once read this. Of course the day I took the pictures this post is referencing it was 100 degrees actual and feel closer to 110.
