And while there are manual ways to correct focus and tune the lenses, some modern SLRs like those from Canon and Nikon, have AFMA systems built in. What these systems do, is allow for the plane of focus to be shifted with intention from where it is currently set (likely from the manufacturing line) to where you want it. Jan 04, 2018 The dot tune method can help you to adjust focus when your camera has been focusing a little in front of or behind your selected subject. You just need some basic photo equipment and the right distance and angle between the camera and a block of text you’ll focus on. Aug 31, 2017 From its humble beginnings, the Fujifilm autofocus system has come an extremely long way. With the X-T1, Fujifilm really started to up the game and provide a reliable and reasonably fast autofocus system. Then they updated it to firmware 4.0 and gave us much more than we expected that little camera to be capable of. Then came the third generation sensor with its X Processor Pro, and that was.
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. Fujifilm has substantially improved the AF-C algorithm to boost the accuracy of the FUJIFILM X-T2's ability to track moving subjects. You can now fine tune how the camera reacts to the way the subject moves within the frame, how fast the subject moves and where in the frame the camera prioritizes focus. Fuji’s new Autofocus System is sure to be a big hit with X-T10 owners, and sooner or later, X-T1 owners and even X-E2 users. The next obvious question in my mind is, what about the X100T? Am I correct in understanding that mirrorless cameras, such as Fuji, do not need the auto focus fine tune feature? If so, that's one of the prime reasons I'm attracted to mirrorless. I'm a bit intimidated by the fine-tuning process, which, from what I've read, can be a headache. In a reflex camera there is a separate AF sensor.
In this photography lesson I will show you a simple method of testing auto focus in your camera, see if you have front or back focusing problem and how to do an AF fine tuning.
INFORMATION FROM THE VIDEO:
Your camera can have back focusing or front focusing problem.
If you focus on the eyes with the wide aperture (let assume around f/2), your DOF should be as it is show in this image:
If you are focusing on the eyes and you get just nose in focus, you have a FRONT FOCUSING problem as it is shown in this image below:
If you are focusing on the eyes and you get ears and hair in focus instead, you have a BACK FOCUSING problem as it is shown in this image below:
Before you do any fine-tuning try to reset your camera first. It might help to fix your focusing problem:
1. Put camera on Auto
2. Go into the Shooting Menu and set it back to default
3. Go into Customs Menu and set it back to default
(Do steps 2 and 3 even if you have never changed anything).
4. Now do a full camera reset (the 2- button reset as shown in your manual) and hold for five seconds.
5. Turn camera off and on again and see if things improve.
Try to do those steps with the lens, you have focusing problems with.

“+” – “front focus situation” – move the focused point away from the camera
“-“ = “back focus situation” – moves the focus closer to the camera
HOW TO TEST AF FOCUS IN YOUR CAMERA:
- Get a ruler and put it on the table.
- Choose a target line on the ruler to focus on.
- Set your camera on a tripod and point at the ruler at 45 degrees angle.
- The camera should be far enough from the ruler to be able to auto focus.
- Use the widest aperture (smallest F-number).
- There should be a good even light and proper exposure.
- Use S-AF/One Shot Single Point focusing mode.
- Make sure that your center focus point is set directly on the target line.
- Take a picture using auto focus. See if your target is in focus. Try a few time.
