I am having a nikon D80 camera. In the display it shows Error. I i click the camera no focus,no picture in the memory card.

Here is a diagram to show the correct position of the switch.

Good big picture and it doesn't matter that it has Canon written on the SD card in the picture the SD card is interchangeable between the two makes.

Now one other thing that may also be the problem is that the SD card needs to be formatted to the camera. Formatting should be done on new memory cards and after you have downloaded pictures to the computer. That's format not delete, delete leaves a mess on the card Formatting cleans the card and provides proper communications between the camera and the memory card

I have Nikon D80 and Shows Err sign on the display. I can not take any pictures. What does this mean

i think the f-- code means its not recognizing your lens correctly. make sure all the contacts on lens and camera are clean. the r11 is the buffer. nothing to worry about. The number of images that can be stored in the memory buffer at current settings is shown in the exposure-count displays in the
viewfinder and control panel while the shutter-release button is pressed. This number is updated as photographs are transferred to the memory card and more memory becomes available in the buff er. If 0 is displayed, the buff er is full and shooting will slow. Shooting can continue up to a maximum of 100 shots.

you can get the d80 manual here if you dont have it

I belive this isn't a fault but more to do with how you are using the camera. The r09 message is to do with the camera buffer and how many more pictures it can hold. You do have a memory card installed, right? The r09 is normally not an error, but simply an indicator of how many more pictures you can take in the current burst before the buffer fills. The number will vary according to the image quality and size settings.

Have you e-mailed or called the techs at Nikon with your problem?

This may be due to the aperture ring in your lens. Try the following:

1. Turn off your camera
2. Move the aperture ring clockwise then lock
3. Turn on your camera and try again.

If this does not work, do the same thing again but turn the aperture ring counter-clockwise.

replace the card

Is the battery charged?
Do you have a memory card in the camera?
Is the card empty?
Is the lock on the memory card off?

In your manual you will find how to change the display format (picture only, histogram, etc.). The time it's taking to display your image "might" be that your memory card is getting quite full and you're shooting large images. I shoot a D80 and it uses an SD card. Make sure you but a fast memory card if your camera does not buffer the inage before writing it to your memory card.

It shows the number of pictures left, not the size of the memory card...
