Viewfinder internal lens array found rattling inside the Camera

Very strange. The lens system that sits between the mirror and the eye piece has become detached. There are a number of rectangular plastic
lenses and what I think are two rectangular metal spring mounting clips, same size as the lenses.. Camera is two months out of warantee and has not been dropped it is used as a spare so has spent most of it's life in a cupboard.

I have been quoted £200 to re-fit the items. half an hours work I would have thought. Can this job be done by a person with a steady hand and lots of patience. In what order do the items need to be re-fitted ?

Please take it to the nearest authorized service center. Since it is out of warranty, you will have to pay for the service. And it is a precision job. So better not to attempt fixing it yourself.

When i put the camera to eye there is a round circle i can see through the rest is black I have tried every nikon lens i own . Nothing changes please help.


I have never used the D2X, but if it is anything like newer cameras, such as the D3, D800, etc., there is an eyepiece cover lever near the viewfinder that allows you to open and close the internal cover. It is used to to prevent stray light from leaking into the camera via the viewfinder when your eye isn't near the viewfinder such as when remotely triggering the camera. If your camera has that feature, it may be closed or partially closed.

Why is my camera taking picture in reverse through the viewfinder?


This sounds like a mechanical problem inside the camera. If it has a flip-up mirror behind the lens, for example, the mirror may be stuck in the up position. Have it serviced by a qualified technician.

I own an Olympus Evolt E-500. Unfortunately, it was dropped and landed on the corner of the case near the battery door. The camera turns on, lcd screen, flash, and shutter seem to work, BUT pictures are...


I found this camera available for purchase as brand new for $450. Spending nearly $300 to repair an older version may no be a wise choice. You may find there is a market for the camera in its current non-working condition on eBay.

With that said, to your questions. 1) It will be difficult to diagnose without seeing it, but I have a suspicion in mind.

The viewfinder picture is actually what the lens sees, bounced up via mirror to a prism that projects the image to the viewfinder. If the mirror has become dislodged and is stuck in an odd position, the image would not be projected in the viewfinder. You can see the mirror when you remove the lens from the body. The mirror should be centered in the opening but at about a 45 degree angle. If it is loose or otherwise in the wrong place, this could be the problem. If the mirror is stuck and preventing the image in the lens from projecting on the sensor (behind the mirror) no capture will be possible. Other than the optics inside the lens and the mirror, there are few parts that could obstruct the image in the lens from reaching the viewfinder. Is the aperture of the lens open? If not, there may not be enough light to see the image in the viewfinder. This would also indicate that the lens is not opening up to let you see, and may not get set to the correct aperture when taking a picture. The camera usually opens the aperture to allow you to have a nice, bright image in the viewfinder. When you press the shutter release, the lens stops down to what the program says (or your manual selection) and the mirror lifts up out of the way, and the shutter fires.

2) Can you fix it? Maybe. Again, without seeing it - its hard to know for sure what the problem is and I don't know your level of skill either.

My suggestion is to bypass the camera shop that "doesn't know what the problem is but will fix it for $270" (how is that even possible??) and deal directly with Olympus USA Service and Support by phone or email to get an estimate / factory trained tech perform the repair.

Good luck!

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.

steve_con_93.jpg

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.

Look at the downloaded images recorded by the camera, if they are okay the fault lies in the LCD and ofteen the system board chip that tranlates a recorded image onto your LCD.

Diopter adjustment and viewfinder problem


Hi
I would not attempt to open the camera for any sort of fix. It has weather seals in place and would recommend sending it in to Canon. If you have any warranties left it would void these. Lastly this is a high proformance bit of kit and you want to get is seen to by an Authourised Canon Dealer.

As for the diopter adustment. To be able to see through the view finder and see your subject clearly, take of the lens cap aim the camera and turn the little dial until the screen inside the viewfinder is clear it should not be fuzzy. You are only looking at the screen/gring and not the image beyond. This does not affect your image but does effect how clearly you see your subject through the viewfinder.

Hope this helps

LCD screen


Unfortunately it is not possible to preview the picture on the camera's LCD screen before you take it.

The 300D is an SLR camera. What this means is that as light comes in through the lens it is deflected by a mirror (which sits in front of the sensor) up to the viewfinder. When you take a picture, the mirror flips up out of the way and a mechanical shutter opens, exposing the sensor to the incoming light. Because the mirror and shutter are in the way of the sensor, it is not possible to have a 'live preview'.

Compact cameras (which do allow you to preview the image on the LCD screen) work in a different way. They have a completely separate viewfinder, and they do not have a mechanical shutter - The signal from the sensor is simply switched electronically between the LCD screen and the memory.

On the plus side, although you might not be used to using a viewfinder, you will find the image you see is a lot bigger and a lot brighter that those you get on a compact camera.

Hope this helps,

Matt

Bundled Eye Piece Cover


The Eye Piece Cover is the cover that attaches to the viewfinder. The eye piece cover prevents light from entering the viewfinder when shooting with your eye away from the viewfinder.
