Canon 30d with tamron af 70-300mm di macro lense, using since 3 months, showing 'error 99'. The error message pops up after clicking the shutter button and no image displays instead error message is displayed. Viewfinder darkens when this message is shown. After removing and putting battery, it works for couple of shots then same error message pops up. Assistance required please.
'Error
99' indicates some problem with the AF contacts. This is a common error
in Canon lenses. It could indicate a very simple problem like dirty
contacts or a much serious one like the breakage of USM cable. Alternately, it can also be a card error or camera error.
First
remove the lens, battery and card and leave the camera like that for
about 30 min. After that, insert a fully charged battery and switch on
the camera. If the error still shows up, it is a fault with the camera
and has to be serviced.
If not, turn the camera off and insert the card. Format the card in the
camera and depress the shutter button. If it shows an error, the card is
faulty.
If not, try cleaning the lens and body contacts (the metal
contacts between the lens and body) using a pencil eraser. Be careful to
hold the body facing down so that no dust falls inside. After cleaning
both the lens and the body contacts, re-attach the lens and try
shooting.
If the error still shows up, you need to take the lens to an
authorized service center.
Hello
The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the
probability is that you will have to get it fixed by a professional.
Use
these at own risk as it may further damage the camera.
Firstly ,
try connecting your ac adapter or usb cable.
Try holding the
shutter button while switching on the camera.
Look at the lens ,
and if some of the lens 'circles' is misaligned or not concentric then
try wiggling it (while holding camera lens down).
Try gently
pushing or pulling the lens when it extends but this is risky as it may
cause the lens barrel to slip out of its guidance system.
Another
way to do this is to place the camera lens down on a hard surface and
then power it up. Be sure to use a soft cloth or something similar as to
not scratch your lens or casing. Let the lens push the camera up and
down a few times and sometimes the little resistance provided by the
camera is enough to get things going again.
Try hitting your
camera near the lens on the body with the soft tissue on the palm of
your hand.
Other than that , I would take the camera to a repair
center for a evaluation to see if it would cost more to repair than to
replace the camera.
If it is still under warranty I would suggest
you take it in before trying any of these steps and remove any
off-brand batteries or accessories as some stores are really fussy about
warranty repairs on camera's with non-brand accessories.
Hope
the advise is useful. please do not hesitate to let me know if you need any further assistance.

Hi Andrea
I get the same error 99 on my Tamron 70-300 1:4-5.6, but i am sure that it is the lens and not the camera as i have tried it on a second camera with the same result. My error 99 only appears when i extend the lens beyond the 180mm mark for all the scene selections, including auto. The only time that the error does not appear is when shooting between ranges 70-180mm and when on sport and macro in manual mode. I have not found a Tamron repairman/repair shop in my area(Cape Town, South Africa) and will possibly have to look at purchasing a new canon 70-300 lens

This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.
