R06 When I get the r06 message the camera won't fire. The number does not get lower.

First, the "r06" message is NOT an error code. It indicates the number of shots remaining in the internal memory buffer, before the camera must prevent additional shutter actuations so that it may transfer those images already in the buffer to the memory card. This "r" number will decrease with each shot taken in rapid succession until it reaches 0. The shutter release will no longer work until the buffer is transferred to the memory card, then shooting may continue again.

As far as not being able to even see through the viewfinder, it sounds like something may be obstructing the light from reaching the meter and viewfinder. The problem is most likely the position of mirror inside the camera body. With the lens off the body, the mirror should be plainly visible at about a 45 degree angle to the opening. A side view drawing of this is below. The solid red line is the mirror in the normal position. The red dashed line is the up position of the mirror when the shutter is released.



When the mirror is in the "normal" position, the light from the lens is projected on a screen so that the image is visible in the viewfinder for composing and can be metered. When in the "up" position (when the shutter release is fully depressed), the light from the lens is projected on the camera's sensor for as long as set by the manual settings or program; based on ISO, aperture, etc. At the end of this time, the mirror returns to the "normal" position.

If your D100's mirror is not in the lowered 45 degree angle position, the image seen in the viewfinder is inside the camera - not that which the lens would project. Hence, the dark viewfinder, long exposure times and - I'm guessing - severely overexposed pictures because way too much light is striking the sensor because the meter is only seeing darkness.

If the mirror is ok, with the lens removed from the body, look for the aperture lever as shown in the yellow circle in the picture below:



By default, the aperture is at minimum. The camera moves the lever from this position to full open (and anywhere between) as needed. You should gently move the lever to the other end of its travel to open the aperture to maximum. Point the lens away from a light source but preferably at a light colored background. Look through the lens. There should be no obstructions and be clear. Next, look at a dark colored background to find the same results. If you want, you can even allow sunlight to shine through the lens onto a sheet of paper (like a magnifying glass). The result should be a bright circle with no obstructions. Obstructions in the lens will prevent the meter in the camera from getting accurate information about the scene and if significant enough, prevent viewing through the viewfinder.

You may wish to have the camera & lens professionally cleaned and serviced to repair a mirror or lens issue.

If this was helpful, please rate it as such. Good luck!

You might not believe this but the biggest CF card for that camera was a 128mb. So I'd say it's time for you to update the camera firmware on the Nikon site it's painless and "Free".

You have two error messagess. !. the r06 message is an estimate of how many remaining pictures the memory card can hold and 2. ERR-is usually a camera malfunction. turn off camera remove and replace the battery. If that does not do it, then if your camera has a reset switch(should tell you in owners manual--My Nikon D70 does), try that. If that does not fix the issue, the camera should be looked at by an authorized Nikon tech.

As far as I can read in the manual there is not any error code r05 and r06. My guess is you are seeing that in the LCD on top of the camera. Turn to page 36 in the D80 manual there you is what you are after. The r05 and r06 are the number of shots remaining in the buffer.

Having received no response in over a month, I assume this is no longer a problem.

Hi,

Could this be the auto focus?
Try this, put what you want to focus on in the center of the screen, in the [ ] part.
Lightly press the shutter button and keep the pressure on.
The camera will focus and then wait.
If you now press the shutter button all the way down the camera will take the picture.

The r06 just means the camera can take 6 more pictures quickly before the picture buffer fills up.
Unless you are using the fast drive mode this will not matter to you.

I hope this helps.

read up on r06 here: D100 FQA

During shooting, or when the shutter-release button is pressed halfway, the number of images that can be stored in the memory buffer at current settings is shown on the exposure-count displays in the control panel and viewfinder. "r06" indicates that six images can fit in the camera's buffer, "r08" would indicate eight frames. Any other number could be displayed as well. Burst mode is used when you want to hold down the shutter button and continuously shoot. You are probably shooting in burst mode and your buffer is full, set the camera to single shot and see if that helps.

The R06 is the buffer indication, not part of the error. It would appear more work is required. Other components may have failed, or the shutter itself may be bad.

I'm afraid this one is not a DIY. Nikon is pricey on repairs, you may fair better checking the repair service search here on Fixya.
