Question about Nikon D50 Digital Camera

1 Answer

Won't autofocus Help! All of a sudden my D50 wont autofocus. It just keeps going back and forth, back and forth, never settling on a focused subject. I've reset and checked everything I can think of. Made sure all the settings are correct. This just happened, it was working fine one moment and the next not! I have a Nikkor DX 18-70mm 1.35-4.5 G lens attached. Thanks for any help from anyone. I've taken the lens off and put it back on again...tried just about everything I can think of! I did notice another post about this but it wasn't helpful because it wasn't specific, something about holding the focus ring...but I had no idea what they were talking about. Karen

Re: won't autofocus

First try another lens on the body and see if the problem is the lens or the body,if its the body the autofocus mirror could be out of adjustment, if its the lens, it sounds like the lens took an impact and needs a pro repair. you should be able to set body to manual focus and focus lens to infinty.

Nikon D50 will not autofocus, the menue item 02 Autofocus is no highlighed and I can not set it

You should check two switches.

First, on your lens, be sure it's set to M/MA not M. That puts the lens in auto focus mode.

On the camera there should be a switch that shows C/S/M. If switched to M, it's on manual focus. Change this to S for single auto focus or C for continuous auto focus.

Nikin D50 autofocus

I figured out that when changing lenses my finger must have hit the little switch and flipped it over to manual focus. I changed it back and it now works. Thanks.

Canon Rbl XT out of focus in viewfndr when shutter half way down

It's possible that the reason the "pictures turn out fairly good" is that your f-stop is set high enough that even though the image isn't properly focused, you have enough depth-of-field to bring your subject into "near focus". Does your lens try to focus back and forth when you half-press the shutter? If not, double check that the lens is in autofocus and not manual focus. You can also try cleaning the contacts between the lens and camera. Take the lens off, and then one-at-a-time clean the contacts on both the lens and the camera, using a clean pencil eraser. Gently rub the contacts. Be sure to hold the item upside down so that the eraser debris falls on to the table, not into the camera body or lens!

If none of this helps the autofocus may have become damaged and you need to have the lens and camera looked at by Canon Repair.

In auto focus mode the lese seems to "hunt" and won't focus

When this happens with my D70s, I know of two options. 1) use manual focus or 2) autofocus on another object about the same distance away from my subject (holding the shutter release half way) and then move the camera back to my subject composition. This seems to happen when there is little contrast in the scene, i.e., a field of same colored flowers. Hope this helps.

Autofocus does not work ( when ON ) with any lenses .

I remember reading a review of the K100D that mentioned that it had poor low light performance. I know mine has a really hard time focusing in low light situations. It does the sweeping back and forth & most of the time never ends up taking a picture. (Even when it bursts the flash to try to focus.)

I've just started experimenting by using a flash light aimed at the subject I want to focus in low light situations, and the camera seems to be able to focus & take a shot more reliably.

If this works, I'm going to rig up something to hold the flash light underneath the camera so that I can use it more often.

I will post an update if this works!

Take Care & Happy Imaging!

Autofocus jumps around and often will not settle on the correct setting

what i do is usually put it onto manual focus then back to auto focus, what it may be is that you are using the wrong lens for your subject :/

D50, blury pics

Blur can occur if the shutter speed is too low relative to the degree of movement of your subject(s). While the 'sports' mode favors shutter speed and adjusts the focus for moving subjects, you may still need to increase the ISO (I'm not sure the camera does that automatically), or use flash, if feasible.
Alternatively, try panning the camera with your moving subject. This should blur the background, but keep the subject from blurring.
Finally, keep in mind that in sports photography, blur is sometimes a desired outcome that produces a sense of motion in an otherwise static photo.

Hope that helps.

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.

D50 After autofocusing stops it still isn't quite in focus.

Your diopter may not be adjusted ( adjustment for sharpness of image in viewfinder on the side of the eye-piece ) so set that first and then try again. If this is correct then your camera is focusing accurately ( on the sensor ) but only the image in viewfinder looks unsharp.
