Hello

Maybe I'm too picky but it seems that pics taken with my D610 and 80-200 AF D lens are out of focus. The attached is a picture of a sign on my neighbor's fence. I set the camera on auto, propped the camera on the roof of my car and took the picture. Does anyone know of AF issues with the D610 or 80-200 af d or am I too picky?

thanks

No way to evaluate from such a small version of the image, but your camera offers AF Fine Tuning so set up a proper subject (not a flat wall) and check its focus, lots of tutorials online if you don't know how. Then take the steps to bring it into proper tune if it is indeed off.

Re: "the camera on auto, the camera on the roof of car" I'm wondering if you used the self timer or pressed the shutter, also on auto, did you shoot at f 2.8 of f8, your camera on auto could dictate the 2.8 which would not be as sharp as stopped down to f 5.6-f11.
Also the photo has a lot of reflection from your car roof so it may be degrading the image.

Not enough information from your image to evaluate and provide a reasonable answer.

But I will say that I have not had great results using in-camera AF-Fine Tuning on a zoom lens - not enough adjustment points. It's ok on a prime, and even then if you adjust for one distance it may not be optimal for another. Sigma has it right - on their 150-600 lenses they give you 4 focal lengths, and 4 distances in each for a total of 16 adjustments - you can really zero in on a good setup with that type of adjustment. There are communication parameters and possibly some physical adjustments that can be made by Nikon which will give you far better results that a DIY approach.

But from your image it is impossible to tell if you even have a problem.

Your image is poor but can't help answer your question.

You need to check "store original" so we have enough detail to analyze and can zoom to diagnose.

Also you need to take an image that has objects at different distances so we can see at what distance the camera/lens is focusing compared to where you had the focus set. Fine tune only adjusts the distance the camera focuses at.

You need to ensure you have the camera set on single point focus and have the point set on the object you want.

Please try again.

If you can provide me your email address, I will send you tutorials I wrote for a class on auto focus micro adjustment. The tutorial will take you step by step through the process and give you some tips that aren't readily apparent on video tutorials. If you want, please send me contact info to charlespkeith@gmail.com.

A single picture of a flat subject isn't sufficient to determine if the picture is out of focus or if you got a lemon of a lens. The information needed is whether objects in front of, or behind the subject are in focus. Having said that, having to fine tune the focus on lenses is a common issue. Some learn how to do it and accept it as a necessary part of owning a DSLR. Some will return their lenses and try their luck with replacements if they can get a refund under warranty or by store policy. In any case, I've had the same problem with several lenses and have been able to use the camera's fine tuning feature to correct the problem. This is only one tool that people use to fine tune their lenses. https://www.bhphotovideo.com/bnh/controller/home?O=&sku=1018336&gclid=CjwKEAiAj7TCBRCp2Z22ue-zrj4SJACG7SBEke7YlvLeC-ZmnDjy4fyqVnq6SozZ3qevPzbnF8Xu9RoC_4nw_wcB&is=REG&ap=y&m=Y&c3api=1876%2C92051678762%2C&A=details&Q=

There are others and even some that you use with a computer. The new Nikon D500 is said to have an auto fine tune function. I don't own that camera, so I don't know how effective it is.
