Question about Tamron Zoom Telephoto AF 70-300mm f/4.0-5.6 LD Macro Autofocus Lens for Canon EOS
I have been using my Tamron 70-300 lens with my Canon 300D for a little less than a year. A few days ago I started getting an error 99 in my Canon 300D when using the Tamron lens only. I have discovered that the problem only occurs when using the Tamron lens and not with other lenses I have. The lens only works without giving error if I use it in the maximum apperture. Once I use a smaller apperture (smaller than 5.6) I get the error 99. Also in a copuple of instances I have noticed that when focusing there is some noise in the motor as it reaches its maximum distance as if the motor was pushing beyond the limit.
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.

I am facing the same problem.
The only way to avoid it is to use it at the maximum aperture between 180-300, thats 5.6.

I have the same thing. When you press the aperture control button (only available on Canon) the diaphragm gets stuck and disconnecting the lens from the camera is necessary.
However, using the lens in the range 70-180mm works fine, also when stopped down. Using the 180-300 range with stopping down produces err 99.
My solutions:
- use the broken Tammy in the range 70-180. Avoid the 300 mm.
- buy a new Tamron 70-300. Having the old lens repaired is not worth trying...
- buy something more solid, like a Canon 70-200 L. Although the Tammy feels ok, its internals are not really built for the road.
