Unfortunately, what you touched was the cameras shutter. You will have to send the camera for a shutter replacement. You need to contact your dealer or the camera manufacturers support in order to find out where to send the camera.
Normally, a shutter replacement cost around $200, depending on make and model.
Hope this helps,

How do I clean the prism for my 7000i Monolta camera

Never touch lens elements or eyepiece with your fingers. If the lens becomes dirty, clean it gently with a lens brush. Only if necessary, moisten a sheet of lens tissue with one drop of lens-cleaning fluid. Then, starting at the center and using a circular motion, lightly wipe the glass surface.
Never lift the mirror or touch its surface, as this may impair its alignment. Dust specks on the mirror's surface will not affect meter readings or picture quality; if they are annoying, have the camera cleaned with soft cotton buds or cloth.

Recently purchased Rokinon 500/1000mm for Nikon D3000 has a black covered filter in the center of the lens...does this come off or is it part of the lens. Also, do the other filters go in the...

This is a mirror lens. Light enters the leans, ir reflected back to the front of the lens by a mirror and is then reflected back to the sensor by another mirror(behind the black circle in middle of lens). DO NOT REMOVE OR TRY TO. To do so will rendeer lens useless.Filters screw on front of lens, like any other lens.

My mirror broke in a kdf-50we655 and i need to know what the size is so i can order it?

First off the mirror in your Sony is not a standard mirror. It's called a "front or first surface" mirror meaning the reflective surface is on top of the clear glass as compared to normal mirror which has the reflective coating behind the glass.The wrong glass will throw the focus off and reduce the much I really can't say. Because of this cleaning the mirror is also very alcohol or windex. Use an eyeglass lens type cleaning cloth with a light touch. As for the mirror size...try measuring the mirror mounting or "holding clips" area to determine the original size. Another trick may be to ask your local Sony repair center about the mirror size because they will most likely be your only source to order the correct replacement mirror.

My Nikon N75 has a black speck in the viewfinder. Does not affect the photos but drives me nuts. Is there a simple way to access and clean the viewfinder?

That depends on where in the viewfinder. If it's the reflex mirror, use a bulb blower to clean it. Don't touch it with anything, and down't use canned air. The underside of the viewscreen can be cleaned with a soft cloth or lens tissue moistened with ethanol or lens cleaner (be careful not to touch the mirror as you do this). The same with the eyepiece.

If it's in the penta-mirror system then it gets a lot harder. You'd have to take the top cover off the body to get to the penta-mirror. Before you try this yourself, consider this. Do you have the proper equipment to make sure everything is aligned properly when you put it back together? An unaligned viewfinder can drive you nuttier than a mere speck (believe me, I've had cameras like that).

If, after cleaning all the accessible sources, it's still driving you nuts, consider having a professional do the cleaning. It'll cost more, of course, but you're much likelier to have a working camera at the end of the process.

My nikond40 shows some black on pictures ,how to clean that

First try cleaning the front and back of the lens, as well as any filter you may have attached. If that doesn't improve things signifcantly, then you've got to clean the sensor.

Remove the lens. Make sure you have a fully charged battery (or the AC power supply connected) then select Mirror Lock-up from the menu. You can use a bulb blower (do NOT use canned compressed air) to clean out the mirror box. Do not touch the sensor (actually, the anti-alias filter) in the back.

There are swabs available from good camera shops for stubborn stuff.

If you're not comfortable touching the most sensitive and delicate component of your camera, take it in to a good camera shop and have it professionally cleaned.

My canon Rebel Xt EOs will not fully focus and take the picture when in automatic focus. It's been doing it for a day or so....I didn't do anything..I took the card out but that's really the only thing...

There are several possible reasons for it, so let me go through them, one by one.

1. Dirty or Defective lens. Check your lens, and if you have a way to get other lens to test the camera, please do it. This includes to check for proper cleaning of both the lens glass and the lens contacts.

Sometimes the iris mechanism in the lens is failing, so there is not adequate light through the lens, which causes this problem.

2. Behind the main mirror, there is the secondary mirror, which is used for auto-focus. I warn you that you have to perform the following with extreme precautions.

There is a spring that is located on the right side of the main mirror (seeing the front of your camera). such srping keeps in palce the secondary mirror. You need to move the main mirror with a tip of a pen (something plastic, not metal) without force so much such mirrors, and don't touch the shutter blades behind the mirrors.

Moving the mirrors you will see ans sense such spring. IF the spring is lose or missing, then that is the reason that such Auto-Focus is not working.

3. Dirty contacts on the camera where the lens is attached. Just clean them (No liquids. Just an eraser pencil or dry wipe will do the job).

4. Defective DC/DC board that controls the lens auto-focus mechanism. Unfortunately, only it can be confimed in a Camera repair shop.

I hope the above can help you to identify why your camera is failing.

If still you need support, please let me know.

Viewfinder Blank

This suggests the mirror is stuck up in the take position. Remove the Lens and look at what is behind it In the rest mode you should see a mirror. If it is stuck up you would see the sensor window Which do you see. with the lens off - can the camera be switched on? This might just drop the mirror The mirror is surface silvered - do not touch it. If it still up then it is a repair shop/warranty replacement job.
