Does the lens stop down when you release the shutter? If it does and the return to fully open - after the exposure - is slow, the lens should be usable. You should note that the exposures may not be spot on - this depends on the lens stopping down to the correct aperture and if damaged this may not happen. Obviously if the lens is not stopping down just prior to exposure, you have a problem and lens is not usable in AE function. You may be able to use the lens in none AE manual mode. Most FD lenses will function correctly in manual mode when the iris is 'sticky'. Your best bet is to buy a cheap film and run a few test exposures - I am sure you will be able to find a local processor, unless you are vacationing in some exotic or remote places!
