First remove the battery. wipe off the battery contacts. reinstall the battery. Battery may be weak, replace.
If that fails, remove the lens. See the mirror in there?
If its stuck in the up position, you can return it by hand. But I recommend a toothpick. It won't leave fingerprints.

Camera not working


Hi Jane,
When we press the shutter release the mirror flips up after the shutter opens and closes the mirror flips down. When it flips down we then see out the viewfinder.

At first blush is sounds as though the mirror flipped up but not back down. Remove the lens look inside the camera press the shutter release what happens?

Cordially,

I advise a high school yearbook and we shoot a d100. Today it's too dark to see through the viewfinder (yes the lens cap is removed), and i ger the r06 error. I've reset the camera, removed and...


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:

steve_con_92.jpg

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!

Inside the camera is a mirror which reflects the scene up to the viewfinder. It flips out of the way when you press the shutter button. When the mirror flips up, the shutter opens and exposes the sensor. When you look inside, if the mirror is stuck in an up position, you will not see anything in the viewfinder. However, the mirror is super delicate....do not touch its surface or try to force it.

I have an olympus om-1 and the viewfinder is black. how can i fix this? I had it in my camera bag safely and today i took it out and loaded it and the viewfinder is black.


Make sure the mirror lockup switch is not activated. Take lens off camera, look inside camera through lens mount and make sure mirror is in down position. When the morror is up, it blocks everything in viewfinder.

Sometimes my viewfinder goes dark and the lens' autofocus stops working. What does this mean, and how should I fix it?


In all probabilities, the mirror lock-up feature of the camera is on. When the mirror is locked in the upright position, the optical viewfinder will go blank. This will also prevent the AF from working. If the mirror lock-up feature is not on, then the camera's mirror box could have been damaged. If this is the case, then the camera would require a minor repair (alignment of mirror) by a service center.

Check the mirror. The image you see in the viewfinder comes through the lens, and is reflected by the mirror. If it's dirty, it will affect the image you see. When you take the picture, the mirror lifts up, the viewfinder image is interrupted, and the light from the lens goes to the image sensor. So...if the mirror is dirty, the picture will be fine but the viewfinder image will be dark or out of focus.

Hi i have a canon eos 400d. i dont know what happened but when i look through the viewfinder, everything is dark. help, please.


It's possible the mirror is locked in the up position. Take the lens off, then look at the mirror. It should be halfway down if it's in the right position. If you don't have a warranty on it, and it's in the up position, you could try giving it a very gentle push. It should travel very easily up if it's not broken.

The viewfinder of my minolta x700 is always black


Check if the mirror is locked or stuck. If the viewfinder is dark, it means there is something wrong with the mirror.

Will not take picture


Some digital SLR camera have a mirror lock and others have a viewfinder shutter In each case this will be a knob in the region of the viewfinder that turns. Check that this model has it and it has not be inadvertently turned. Then come back
