1. What would exist the best mode to become about cleaning the lens contacts on both my lens and my 50D? I've gotten Err99 a
   couple of times, merely I've heard a lot of times cleaning the lens contacts can set it, so I idea I would give
   it a endeavor. Thanks!

2. Use a pencil eraser - works best!

4. I utilise Caig DeoxIT, a product designed specifically for de-oxidizing electrical contacts. Caig products tin can be purchased directly from Caig at http://store.caig.com, of from one of their many retail distributors. Cheque the "Distributor Info" tab on their web site.

5. Whatsoever alcohol pad will practice the job (ie: Vodka on a T-shirt). Sandpaper volition do a better job and then pencil eraser aka: Use eraser only as last resource as it can take abroad a fleck of gilt finish and make matter worst later on. . Also, old the pins on the photographic camera body get gum up also.

6. Some other vote for the eraser. No need to mess with annihilation else. It is also the first proposition made by Canon's tech people.

7. Pencil erasers, esp the ones on the finish of a pencil are really practiced at removing the microscopically thin gold coating on the pins, that way you will be buying new hardware or getting it repaired sooner than later. They are very abrasive. Now a Pink Pearl or similar art gum one is much better to apply, if yous take to utilise an abrasive.

   Otherwise booze or lighter fluid on a cotton swab is a much better choice, and won't exit annoying laden rubber $.25 floating around inside your photographic camera or on the back of the lens.

8. Bob, if the person is using the eraser so firmly that it leaves safety $.25, they are using it as well firmly. A few light swipes that leave no residue and practise not damage the contacts is all that it takes. This is a very occasional operation. I don't think that any lens of mine has needed it more than in one case.

9. I generally use isopropyl (rubbing) alcohol on a clean cloth. If you look at nigh "electronic contact" cleaners,
   y'all'll find they are simply isopropynol and purified water... exactly the same equally "rubbing alcohol", but about
   20X or 30X the price.

   For use on location, I have a package of "wipettes" pre-moistened with isopropynol. These are really for
   computer keyboard and similar cleaning, but work fine on cameras and their contacts, too. They cost more than, about
   $10 for a pack of 70 or 80, if I recall correctly, simply they are more convenient that taking a bottle of rubbing
   booze along.

   I won't employ pencil erasers and am a bit surprised Catechism recommends it on their website.

   Erasers are fabricated with vegetable oil. What's often the problem on those contacts is a very lite coating of oil
   (finger oils, manufacturing oils, etc.) inturrupting the tiny electrical flow. The terminal thing I desire to exercise is rub
   something made from oil onto the surface, possibly leaving some more residue! (Always observe how sometimes a pen
   won't write over an area that'due south been erased?)

   In that location'due south besides the concern Bob mentioned, that any dust in the eraser might actually do impairment to the coatings on
   the contacts. Finally, I really don't like risking getting whatsoever pieces of eraser falling downward into the camera.

   DeOxit is a very good product, but probably overkill for this situation. Oxidization is usually non a problem,
   the contacts are aureate-plated specifically for that reason (gilded does not oxidize).

   Never *e'er* use a cotton swab (Q-Tip) anywhere inside a camera. Very risky! This is one of the showtime matter
   camera repair techs are taught. Common cotton fiber swabs shed tiny cotton wool fibers that tin completely jam shutter and
   other mechanisms and you tin can easily terminate upwards with some expensive repair bills.

   The only exception would be swabs specifically made for optical cleaning, which exercise not shed fibers (most aren't
   "spun" cotton fiber, anyhow).

   In add-on to cleaning the lens-to-camera contacts, make sure you lot have the latest firmware installed and watch
   for whatsoever firmware updates. Err 99 is sort of a "grab all" error code and in that location could be something entirely
   unrelated to the lens-to-camera contacts going on, that will be addressed in time to come firmware revisions.

10. First approach: Rub/polish firmly with a microfiber cloth.

    If that doesn't work, moisten the fabric very lightly with denatured booze (with no water content) -- not enough to drip. Rub again. (You don't want fluids, specially h2o, wicking into the camera or lens.)

    If you feel you have to use an eraser, at to the lowest degree use a gum eraser that has been pre-cleaned with alcohol, and don't rub difficult plenty to shed any rubber. Only I wouldn't recommend it.
