20 Most Recent Tokina Zoom Telephoto AF 80-400mm f/4.5-5.6 AT-X 840AF Autofocus Lens (with Tripod Collar) for Minolta Maxxum Questions & Answers

Unless you have a lens collimator and other equipment necessary to ensure proper alignment when reassembling the lens, don't do it yourself. Take it to a camera shop and have a properly trained and equipped professional do it.

What about it, and why do you want it ? It is simplicity itself - attach the lens to the camera, switch on the camera, frame the subject and shoot.

THIS IS NOT POSSIBLE WITHOUT SPECIAL TRAINING AND TOOLS. SEND TO AUTH SERVICE CENTER OR REPLACE.

What does the FEE or error message displayed on an SLR camera mean... The link is to a Nikon error page which explains what could cause this error. Is the lens set to the smallest aperture? If not this would cause this error.

This will depend on the lens you have now.

Some Tokina lenses have a universal fitting, with a separate adaptor mount for each camera body they fit. Its usually the last 5 - 10mm of the mount, and its identifiable by a second release button, which allows the specific fitting to be changed. If you have one of those, you just need the Nikon fitting.

If the P/K mount is an integral part of the lens, you have a couple of choices.
(1) You could get an engineering shop to alter the mount. This costs a lot and probably isn't worth the hassle. (It might be better to sell your lens and buy the nikon equivalent).
(2) You could use an adaptor. These are readily available on eBay.
For example:

Note that just because it has the right (i.e. Nikon) fitting, it doesn't mean that it will necessarily have full functionality on the body you intend to use with it.

Some Nikon bodies are "extremely fussy" about which lenses they can use, and it might be worth evaluating whether your proposed solution would work with the camera body you have in mind before committing to any sort of expenditure.

Err99 is very difficult to diagnose without having the camera/lens looked at by a good reapirer who can actually extract more detailed error messages from within the camera itself that are more helpful than just the "Err99" message that shows on screen. Err99 could mean 100 different problems as it is a global Canon code error... Some of the causes could be:

Lens/camera electrical contact failure

Lens circuit (AF or IS) failure

Camera electronic circuit failure (see below)

Battery or Grip problems

Broken or stuck lens aperture diaphragm – Note: this most often happens only when the lens is completely stopped down. If you have questions about the lens, shoot it both wide open and stopped down. If ERR99 appears when stopped down, its an aperture issue.

Older third-party lens with incompatible electronics

Jammed or damaged camera shutter curtain

Mis-formatted or damaged card

Damaged or corroded cell within camera battery

Failure of the sequence motor—according to precision this is unusual, but does occur, especially in older cameras that have been through a shutter replacement.

Corroded battery or camera contacts

Incorrectly mounted battery grip, particularly if it’s too loose

Camera/hot shoe electrical contact failure

Moisture condensation within camera or lens (or corrosion occurring days or weeks after moisture exposure)

If none of the above seem to fix the problem, your next best shot is to seek repair (if it is worth doing so).
