1. Aug 31, 2017  The auto Fine Tune helps a lot. But on my D500, it's quite hard to work on Zoom lenses fine tuning. My old 17-55mm f2.8 suffer of a small back focus at 17mm and front focus at 50mm.

This post describes an autofocus test chart I've developed, why I think it's better than others I've seen, and how to use it to test the autofocus of your camera and lens: If you suspect that your modern SLR or SLR lens has autofocus problems, you can use a chart like the one offered on this page to perform some tests. Some AF fine tune.

You can use this online Target Distance Tool (see below how to do this within FoCal) to suggest a suitable target distance for AFMA / Focus Fine Tune lens calibration with Reikan FoCal.

5. The best set of images was taken with AF fine-tune turned off. The set taken with an AF fine-tune adjustment of -6 were among the worst of the lot. After testing both lenses, I’ve decided to store a -6 adjustment for the Tamron lenses but to leave AF fine-tune turned off. Both lenses make sharp, usable images without an AF fine-tune adjustment.
6. Tune your camera autofocus at the touch of a button. Did you know your camera's autofocus can be adjusted to work optimally with your lenses? Reikan FoCal is a software tool that takes control of your camera, guides you through the setup and fully calibrates your camera autofocus with minimal interaction from you.

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. Nexus 2 vst plugin fl studio free download. 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.

Jun 24, 2018   Set the camera up on a tripod, aimed at a suitable AF target with good lighting. The auto AF fine tune feature will not operate under dim lighting (under LV 5 or so) even though AF is rated down to LV -4. Engage Live View and make sure the LV focus mode is.

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.)

“The typical way Auto AF Fine Tune is performed by most users leaves a LOT of room for errors, inconsistency, and can even make things worse,” Perry tells PetaPixel. “In this video, I outline what AF Fine Tune is, proper setup, and a technique that gets me VERY similar results to what I see with commercial products.”

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.

Check out the full video above to learn how you can utilize this feature and properly calibrate your camera and lenses.

• Auto AF Fine-Tuning

Auto AF Fine-Tuning

The D500 can fine-tune autofocus automatically. The results can be used with all lenses of the same type.

Use only as required. AF fine-tuning should be performed at the focus distance at which the lens is normally used; fine-tuning performed at short focus distances may be less effective with distant subjects and vice versa.

1 Ready the camera.

Mount the camera on a tripod and aim the camera at a flat, high-contrast subject parallel to the camera focal plane. Note that auto AF fine-tuning works best at maximum aperture and may not function in dark surroundings.

2 Start live view.

Rotate the live view selector to and press the button.

3 Adjust focus settings.

Rotate the focus-mode selector to AF and use the AF-mode button and command dials to select the following:

• Autofocus mode: AF‑S
• AF-area mode:(wide) or (normal)

4 Select the center focus point.

Press the center of the multi selector to select the center focus point.

5 Focus.

Press the shutter-release button halfway to focus, then zoom in on the view through the lens to confirm that the subject is in focus.

7 Save the new value.

Highlight Yes and press to add the AF fine-tuning value for the current lens to the saved values list (CPU lenses only). Note that only one value can be stored for each type of lens.
