How to open and clean inside viewfinder and prism in Nikon F100

I didn't use my f100 for about 3 years.
i have humidity or moisture on the inner side of the viewfinder and pentaprism of my nikon f100 .it is visible from the viewfinder and from the body - where the focus screens can be changed. i already screwed off the first lens of the viewfinder but it seems to be on the inner side.
please tell me how to open it .e.g. what are the screws i need to take off, what part to pull ..

Thanks for your email. In the meantime I learned my problems were not uncommon with early production F100s; the culprit is the switching circuitry under the film advance mode dial, which has to be replaced. Essex Camera of Carlstadt, NJ, will do the repair, including general service, at a cost of $ 150. Sincerely,

Tom

I thought I loaded the film in a Nikon F100. The Camera showed the film was moving 1-24 I got to 24 the film re-winded I took it to get developed and The film was clear I just need to know how the load...


Since you managed to close the back of the camera and shoot, you've placed the actual canister into the camera correctly.

What happened is there are a series of pegs on the left side of the camera, or sometimes just a red indication line, that the film must be placed onto. If you don't lay the film onto this, the camera won't pull the film out of the canister when you shoot, but it will rewind it back into the canister correctly when it thinks you are out of shots. This will result in a blank roll of film.

On my Nikon F, i have the correct replacement batteries in, but..


If, in all other respects, the camera operates correctly and the exposures are correct, then your camera probably has a bit of corrosion or excessive wear on the electrical contacts inside the check meter button.

If so, the best option is to simply live with it until you decide that the camera needs it's next professional CLA service (clean, lubricate, adjust). It's also worth checking inside the battery chamber to ensure that the battery contacts are bright and clean, but dirty contacts would also result in wrong exposures as the meter wouldn't read correctly all or some of the time.

Camera with a sticky substance on the back


It's a very common problem with older cameras and is an irreversible breakdown of the foam which was used to provide light-proof seals on the camera back and also to cover the pentaprism and provide a mirror buffer. (The pentaprism and mirror buffer are part of the viewfinder system).

The first problem is that when the foam turns to goo it allows light to leak into the camera and spoil the film, but that's the least of it. Where it gets serious is that the goo spreads inside and can gum up delicate moving parts; worst of all the goo is somewhat corrosive and can damage the coatings on the pentaprism leaving permanent residual ghosting images in the viewfinder.

The good news is that it's a well understood problem and every professional camera repairer can remove the goo and restore the camera as part of the regular service that all SLR's should periodically undergo. The foam will be replaced by modern materials which do not degrade. Some repairers also replace the mirror buffer, others will just remove the old foam and omit the buffer, but I always insist on a new buffer. At the same time, the repairer will give the camera a thorough CLA service (Clean, Lubricate, Adjust) which for a camera in non-professional use will often see it through a few more years, but I'd recommend getting a CLA done annually if you're well off and every couple of years if funds are tighter. The CLA will also ensure that the light metering is correct and on cameras using the older mercury oxide batteries can include a meter recalibration to allow use of modern silver oxide equivalents which have a higher voltage as the mercury cells are no longer available. (Some folks use manganese dioxide batteries, but they start off at a voltage slightly higher than the camera was designed for and constantly drift down with use to way below the nominal voltage, so metering is neither consistent nor accurate). A regular CLA with foam removal costs a bit more than a regular CLA but is a once only expenditure. Some repairers charge for recalibrating the meter for silver oxide batteries, but most won't if you politely explain that you can always take the camera elsewhere.

DIY kits are also available and some are very good indeed, but they can be fiddly and messy to fit and none of them address the more serious issue of the pentaprism. In practice, repairers will remove the old foam from the pentaprism but almost never fit a replacement. It's not strictly necessary and the reluctance to fit a replacement stems from the risk of further damage to the pentaprism by the adhesive. The outside of the pentaprism is normally painted black from new, but foam goo usually attacks the paint and partially removes it. it also attacks and removes any optical multicoatings on the prism. When this has occurred there is no fix: the problem will not worsen once the foam has been removed but there will be residual damage visible in the viewfinder as ghostly dull patches, but this is something which can be tolerated and will not affect image quality.

If you want a cheap quick fix, then use a q-tip (UK= cotton bud), a wooden cocktail stick/toothpick and some alcohol to remove all visible traces of gooey foam. Omit the mirror buffer altogether and take your chances with the prism foam. To replace the rear light seal just use a length of woollen yarn: you'll find that if you twist it slightly it will reduce in diameter and allow you to press it into the slot where the foam was using a toothpick. Usually you can get away without gluing it, but if any glue must be used then use a few very sparing dots of something easily removed such as Copydex or the rubber cement sold for repairing bicycle inner tubes. At the hinge end of the camera back will be a thicker, wider bit of foam. Just use a few dabs of glue or to secure a good thick double or even triple width of yarn. The fix isn't a professional one, but it's good enough and was how the seals were made before rubber foam was invented. It also buys you the time to decide whether you like using your Nikon enough to invest in a professional CLA with the additional options.

I hope that my reply has given you a few options and will enable you to get your camera into working condition again. All I ask is that you return the favour by taking a moment to rate my answer.

XG9 Battery/Shutter/Aperture mirror


first clean the battery cap and contacts with a pencil eraser including cap threads.
the aperture mirror is located on front of the prism. remove the two screws on the front prism cover, remove the cover. you will see the holders for 2 tiny mirrors one of the mirrors fell off and must be found before it gets jambed in the mechanism.if it's not around the prism anywhere take off the bottom cover and check there. gently shake and tap the camera . the mirror has glue on the base side and may be stuck. when found re-glue to the holder.

Nothing happens when I turn the camera on.


First would be to check your batteries. If they are good look inside the battery holder see if there is battery corrosion, if so it should go to Nikon for CLA.
