Re: d 50 focus problems

This sounds to me as if the sensor in the camera has become angled slightly from abuse or manufacturing defect.  If you think about what is happening when you focus the lens, it is that the focal point is being moved forward or backward until it is exactly in the vertical plane that the sensor is in.  That is, unless the sensor is no longer in the vertical plane.  In that case the focus point is in front of some of the sensor, and behind some of the sensor, with it being on the sensor only on the line across the sensor that is where it is supposed to be.  
You can probably test this by intentionally mis-focussing.  This should shift the line that is focus above or below the line that you have now.  
If you did not do this by sticking something against the sensor and the camera is under warranty, Nikon should fix this.  In my experience, if you didn't do this by abusing the camera, and if Nikon has ever seen this before, and if you had registered the camera with them, and if you talk to Nikon tech support and are polite and respectful, etc., there is a better than 50% chance that they will fix it at no charge anyway.  
I hope that helps. Good luck.

I own a Nikon D50 and the 55-200 lens will not autofocus (lens continually extends then retracts but never locks into focus). Ive read that depressing the lens release button whilst holding the lens in...

Why don't you just clean the sensors properly? Remove the lens and clean the contacts on both the camera body and the lens with a cotton swab lightly dampened with rubbing alcohol. There's a 50-50 chance something else is causing your problem but try the cleaning anyway.

Help black line on bottom of picture.

After a bit of experimenting, I have found a solution that works in my case. The problem was the shutter speed. At 1/200 I got the black line on the bottom of my pictures, but when I tried it at or below 1/100 it was gone. Hope this helps.

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.

Nikon D50 LCD Display does not work

NatD, The D50 and indeed most SLR digital cameras [ I have a D40 ] does not allow you to take pictures using the LCD display ... this is by design, you are meant to use the viewfinder and the image you see through it is straight through the lens via a mirror block [ called a reflex pentamirror or prism ]. When the mirror is down such that you can see the image in the viewfinder it is obscuring the sensor [ the bit that takes the picture ] and when you take a shot the mirror lifts and the picture is recorded. Its this reason that DSLR's dont use the LCD to shoot, however there are a few now available that do let you do this, such as olympus, new panasonic one and higher end Nikon and Canon cameras. Hope this explains it without getting too detailed!

I have this problem too - Nikon have looked at the camera and said I set up a custom setting so that the focus only works when you press the AE/AF Button (!). I also had a problem with the flash not working - its looking like this is a known problem. I think I was sold a Turkey
