I have a rebel 350d and err 99 comes up when I use my canon 70-300 lense.It will work only with flash on and as soon as flash is not available it will not work.

I have tried cleaning the contacts and in different modes,so assume it is something gone wrong with electrical circuit in lense as all functions work otherwise.

Have bee quoted £100 for overhaul so will be cheaper to buy a secondhand lense.
