Here’s a 12-minute video in which photographer Steve Perry shows how to use the relatively new “Auto AF Fine Tune” feature from Nikon.
If your camera is back or forward focusing, then it’s likely you need to fine tune the autofocus. Often this would involve buying a commercial kit, or doing a bit of guess work, and in more extreme cases even sending your DSLR back to Nikon itself.
Apr 21, 2016 In this case, for this lens paired to this body, automated AF Fine Tune found a value of +14 was best. This indicates that for correct focus, the camera has to shift focus backward an arbitrary 14 units from the focus reading the phase-detect sensor makes.
However, that is set to change with the Auto AF Fine Tune feature that is present on cameras like the Nikon D5, D500, D7500, and most likely any future mid-to-pro level cameras. (Here’s looking at you, D850.)
This code is working in NetBeans, but in Dev-C, I am just getting the message of 'we are connected to the file', but it is not putting the value of '10' into the file. Re: Dev-C Reading from text file From: Robert Alatalo - 2005-07-09 13:58:29 Also, note that not all line wraps actually add a newline.sometimes they ONLY wrap the display and allow the line to remain a long line in the file. Jun 29, 2010 Trouble reading from a file in dev c. I have written up a c program that will read from a file. The file consists of only numbers ( from 1 to 50) and spaces with no other special characters. The main aim of the program is to tell me how many times the numbers appeared in the file but whenever i run my program it always hangs. When the file is closed: before closing a file, all buffers that have not yet been flushed are synchronized and all pending data is written or read to the physical medium. When the buffer is full: Buffers have a certain size. When the buffer is full it is automatically synchronized.

This example opens a file for reading. This is useful for reading text files but does not work for binary files.
- The camera can store values for up to 20 lenses; to fine-tune additional lenses, attach them and repeat the steps above. Note that fine-tuning values are stored by lens name (focal length and maximum aperture) and that only one value can be stored per name, although values recorded with teleconverters attached are saved separately.
- Welcome to the forum, does the 810 have auto fine tune like my D500? Live view as far as i know cancels out any front or rear focus problems due to it focusing on the sensor, unless its needed for a auto fine tune which i never had much luck with on the D500,used the old fashioned manual way on my D500.
- Fine-tune focus for up to 20 lens types. Use only as required; AF tuning is not recommended in most situations and may interfere with normal focus. Auto fine-tuning is available in live view (0 Auto AF Fine-Tuning). We recommend that you perform fine-tuning at a focus distance you use frequently; if you perform focus-tuning at a short focus.

By using a target that is full of information for the autofocus system to lock onto, as well as ensuring it is properly lit, you can properly fine tune your camera’s focus for different lenses.
Unfortunately, you can only set a single fine tune preference for each lens. So for zoom lenses that have a varying AF compensation value across their range, you’ll need to compromise and go for a mid-point.
