Question about Nikon Cameras

1 Answer

Back focus? My Nikon d3200 is back focusing. Tried several different lenes with the same result. What's wrong with it? Haven't used this camera very much as it was a backup. I still have the original box it came in, looks new still. What could it be? Not set right at the factory?

That is a common problem, take the camera to a professional service for a calibration

SOURCE: The auto focus is not working on my Nikon D50

I assume the AF/M switch on the body is set to AF as well? This has not been mentioned but the D50 has two drive systems for AF.

SOURCE: Front/Back Focus Problem at Sigma 30mm F1.4 Lens

Hello Abdul!
I recommend that you print this test chart: http://www.photo.net/learn/focustest/scale45.jpg
Just print it on an ordinary paper, then put it on a table, and take a picture at it from a 45 degree angle, using the center focusing point only, aimed at the thicker line in the middle. The numers are centimeters. Take the test picture at f/1.4. Make sure you have good light so you get a fast shutter time. If you have a tripod, mount the camera on the tripod prior to taking the test picture.
Then examine the picture in your computer, zoomed to 100%. Now it should be clear wheter you got back- or front focus, and how large the problem is.
Unfortunately, there is no way for you to adjust the camera and lens combination yourself, you will have to send/bring the camera to an autorized camera workshop. This is covered by the warranty.
Hope this helps!
Regards, 
/Chris

SOURCE: D90 Nikon autofocus problems

Try a reset (hold down both buttons with green dots next to them) and see if that helps.

Also try cleaning the contacts on the lens itself (light rub with a pencil eraser usually works well).

I was able to fix the problem nut it requires several steps and only offers a temporary fix (untill the calculator is reset then it needs to be done again).
1. Press F5, then Dimond (symbol on buttion) then "Clear"
2. Press "alpha" then "S"
3. Press "0" dont mess with anything else here
4. Press "2nd" then "Quit"
Now you can turn it off but are missing the bottom text (rad,auto, etc...) to fix
6. Press "Mode" change radian to degree then "enter"
Now the text is displayed showing the mode.
7. Set the mode back to radian by reversing step 6.
Thats it I dont know how to get the bottom line back though...

How can I determine which Sigma and Tamron lenses will work with my Nikon D3200? (I know they have to fit my Nikon F mount.)


There are three things you have to consider when getting lenses for the D3200.

First, you already know that the lens has to have the Nikon F mount.

Second, in order to autofocus, the lens must have a focus motor since the D3200 doesn't have one itself. Sigma designates lenses with the focus motor as HSM. Tamron designates theirs as USD. Lenses that don't have the focus motor will still work with the D3200, you just have to focus manually.

Third, the lens must have the electronics to communicate with the camera in order for the exposure meter to work. Any Sigma or Tamron lenses designed for digital cameras will have the electronics. Older mechanical lenses, including those from Nikon, will still work with the D3200, but you must set the exposure manually, without any help from the camera's light meter.

How to use Nikon Pk-3 extension tube?


It should work with just about any lens, though it works best with moderate focal lengths (say about 24mm to 200mm). Its primary purpose is to let the lens focus much closer than normal.

When you say "no results," do you mean it's not letting you focus closer? Mount the tube on the camera, mount a lens on the tube, then focus the lens to its minimum focus distance. Looking through the viewfinder, move closer to an object until it comes into focus. Does it come into focus? How close? What lens(es) are you trying?

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.

Nikon D5000, when I try to take a picture everything is blurred and of course as a result the picture is as well.


Hi, the focus indicator LED lights, and some part of the scene is in focus, but not the object of your photo (af afs central area).
This is perhaps a back focus problem and needs service from Nikon to make the correction.

How to use auto fouse


The D40 does not have a focus motor, instead relying on a motor in the lens. This lens does not have such a focus motor, and thus will not autofocus with the D40.

Ive got the nikon d40. when i take photos close up they are blurred. there r 2 settings on the focus lense one is letter a one letter m. you have to move switch to indicate one or other. camara wont take...


The letters you're referencing is the M/A (manual / auto) focus switch. The lens has this switch and operates in Auto Focus mode when set to "A" and manual focus mode when set to "M".

You have to manually focus on the subject when in letter "M". If you do not, the result will be out of focus. From your description, it sounds like the camera / lens combination is attempting to focus and operate the shutter in auto, and focusing in manual; but due to some type of damage resulting from possible mishandling, exposure to dust, dirt or even moisture is interfering with the successful completion of the process.

You could isolate the problem to determine if the cause is in the lens or camera by simply attaching the lens to another compatible Nikon camera or placing a different auto-focus lens on your D40. The problem will either stay with your D40 or follow the lens when attached to a different camera. It is also *possible* that due to numerous attempts of auto-focusing with your D40 & lens combination, that both the lens *and* the camera have been damaged. If the problem is severe enough, the problem in the failed device could cause failure in the otherwise normally working device, too.

You might be best served by contacting Nikon Service & Support below:

You also said you lost your manual. You can download the manual for the D40 directly from Nikon in your choice of English, French or Spanish from the link below:

If the AF is set to release then the camera will release the shutter before focus is attained. Set it to focus only and see if it improves. Don't leave it like that, you will miss pictures.
Shoot some pictures with the center AF point only in single release and see if the focus is consistently landing in front of or behind what you wanted in focus. A penny on the sidewalk shot at a 45 degree angle in aperture priority with the lowest A number possible is a good quick one. For super fine tuning with a f2.8 or faster use a fuzzy plant branch like a tomato plant. If whats in focus is always in front of or behind what you focused on then you need too adjust the focus(back focus) in AF fine tune until it lands where it should. It's an annoying process that involves shooting, adjusting, shoot again, see if its better or worse, adjust, shoot and repeat. On zoom lenses use the middle on the zoom range because it will usually go from back to front focusing on the long and short end. The camera remembers each lens and the process must be repeated for each lens.
Last thing I can think of is the one that no one wants to hear and is most likely the problem, Camera Handling. People have a tendency to get sloppy after getting use to a camera. I have noticed that the VR lenses don't like people that stab the shutter button. It wants to remove fine vibration and a harsh stab makes it jump back to center and if the shutter opens at the same time it will put fine motion blur in the picture and looks out of focus.

Camera won't autofocus


Auto-focus technology on this camera is controlled by several contacts on the mount that physically mate with other contacts on your lens. It sounds like your mount may be malfunctioning due to wear and tear (if cleaning does not work). This is between $100 and $300 fix depending on which part(s) need replacement.

Auto focusing problem


Your camera is only compatable with AFS-type lenses because it has no screw-drive motor.  You can only use AFS Nikkors and Sigma HSM lenses (the lens actually has a motor inside).  You were misinformed.  Bring the lens back and ask for a refund. Take that money and purchase a compatable lens somewhere else.
