Nikon D70 is freezing up. I have no idea what I may have done but when I push the button to take a picture nothing happens and r09 flashes

an r # (r09 or r12) is the cameras estimate of how many remaining pictures can be shot on your memory carde. It is not an error. The camera works, does it not?. If something else is happening let us know.

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.

I have had "dark pictures" from each of my Nikon DSLR (D70, D80, D200, D300) cameras usually when taking pictures from a tripod and/or the self timer. Situations where you take your eye away from the viewfinder which allows stray light to enter thru the viewfinder and throw the auto exposure way off. Not sure if this is what is happening to you.

R09 or R07 etc. is not an error message. In Nikon lingo ERR is the one you need to worry about. The RXX refers to the approximate amount of shots left in the buffer in the camera. Not a ptoblem. You may be trying to take pictures faster than your memory card / camera buffer can handle.

You can try a fster card like 266, but you may find that the camera is also your limitattion.

If you make no changes at all, the camera buffer will eventually clear and you can again takes pictures.

It sounds like you should try a new set of batteries in the camera. I have a similar camera and the flash is the first to go when the batteries are dying.

I hope this helps,

First, the r09 refers to the amount of memory buffer photo storage is available. That's to say that 9 photos can be stored in the memory buffer, while the latest pictures are being written to the slow camera card. It's bursting 9 photos. Depending on your image quality and type, this will be a different number.

Second, make sure you are in the P or Auto mode while testing, or clarify what mode and settings you have. A picture won't take on my D300 if my lighting is too low for my current settings.

Push your playback button once the camera is on.
Then push you your thumbnail button. (this is the second button from your playback)
watch your monitor and keep hitting the thumbnail button until you get to the single picture view.

The "For" message means you need to format the memory card.

Copy anything you don't want to lose off of the card.

Locate the LCD Illuminator Button (next to LCD on top) and the Shooting Mode button (next to Brackting button (BKT) on back). Next to both of these button should be the word "format".

Simultaneously press and hold both buttons for two seconds. The card will format. Once done, the LCD will display the number of pictures available to be taken on the card.

Check the depth of field preview with the lens on and the camera on. If the aperture does not react, it may be a problem with the lens rather than the camera. Check the camera with another lens if you have one.

According to my information, the camera may need a new flash PCB (printed circuit board). Check the repair service search on this site for someone in your area. The part number for the circuit board is: 1S014-020-1 and runs about 50$
