The manual focus ring on my camera doesn't work. The ring turns but does not seem to adjust the focus. Automated focusing still works. How to fix it?

Let me start with a guess. There is a diopter adjuster just behind the viewfinder. If it is adjusted way off from the correction you need, everything will look no better than out of focus though your photos may look fine. Google how to adjust the diopter setting on the D3200 and see if that won't take care of the problem.

Here is one of the secrets: your camera has so many adjustments that if someone else picks up your camera, they may change a setting leaving you wondering what happened and why. Be cautious.

If that guess is not the cause, let us continue. Are you saying that when you switch the lens setting from A to M, it still will not manually focus? Some of the lenses are mostly made for autofocussing, so the focus ring that you have to turn for manual focus could be narrow and out at the very front of the lens. If you cannot manually focus, something may have happened to the inner works of your lens. Try another Nikon lens to see if it will autofocus. If it does, your lens requires servicing or replacing.

Good luck. Hope you get back to shooting soon.

It may be that the focus ring is only engaged when the lens is switched to manual focus.

Probably needs a new ribbon cable in the lens. This flexible cable maintains the contact as the lens is zoomed in and out. If it is still under warranty take it back to B&H for a simple repair.

Hi,

I think focusing ring got stuck or jammed. What you can try to do is spray some compressed AIR into the lens to try to free up any sand or dust that may have worked its way in. If that doesn't help, you can gently bump the camera to try to free the focusing ring.


or.......

You can try to turn camera ON at the table (facing it to the ceiling), don't put camera down face to the floor when opening.

Else your camera need to be disassembled to get at the focusing ring at Service Center.


Good luck and have a nice day.

Rating the solution is highly appreciated.

Because the camera has a different focus point from the eyepiece. TURN the focus knob until the camera comes into focus. OR you can buy a "focus ring" for the eyepiece which attaches to the barrel of the eyepiece and is adjustable-- then focus with the camera FIRST and then insert the eyepiece with the ring on it and lift it UP until the image comes to focus-- then tighten the ring. NOW you can use that eyepiece to roughly focus the camera.

1. Power-Cycle your AVerVision Document Camera to reset the focus motor.
2. If your Camera has Auto focus, Press the auto focus button on your document camera's control panel.
3. Reset your camera to Default by Pressing MENU > Default > Yes > Enter. Then Power-Cycle your camera.
4. Check your output device's focus adjustment.
5. Power-Cycle your AVerVision Document Camera to reset the focus motor.
6. If Manual Focus adjustment is available on your camera's remote control, try adjusting back to focal point from the remote.
7. If your camera has a Manual focus knob, manually adjust the focus by turning the focus knob located on the camera head.
8. If adjusting the focus knob does not focus the image, please click here http://support.averusa.com/kb_article.php?ref=9869-UMJQ-1105 for instructions on how to fix the focus ring.

I have the same problem. I can make it temporarily work by manually turning the focus ring until it is out fully. Then it will auto focus and take photos until I turn the camera off or it times out. Then I have to repeat the process. It's annoying, but at least it works for me. Try it and post to let me know if it works for you

Are you sliding the switch from "Auto" to "Man" first? The focus switch is located at about the mid-point of the camera, just forward of the flip out LCD. The focus ring is the larger of the two lens rings, the one farthest towards the front of the camera. The smaller ring behind that one is the zoom ring. Also, make sure something isn't inadvertently pressing down the "Push Auto" button immediately below the focus switch - that can force the camera to autofocus even if in "Man" (manual) focus mode. Hope that helps!

There is no secret locking switch. If a little gentle jiggling doesn't free the zoom ring, then I can only suggest you take it in to a reputable camera shop for a Clean-Lubricate-Adjust (CLA).

There are four focus modes: S-AF (Single auto focus), C-AF (Continuous auto focus), MF (Manual Focus), and S-AF/MF (Simultaneous mode). (SINGLE Auto Focus): Focusing is performed once when the shutter button is pressed halfway. C-AF (CONTINUOUS Auto Focus): The camera repeats focusing while the shutter button is pressed halfway. (MANUAL FOCUS): The function allows you to manually focus on any subject while looking through the viewfinder. SIMULTANEOUS USE of S-AF mode and MF mode: You can fine-adjust focus manually by turning the focus ring after AF is performed in the S-AF mode.
