My Tamron 17-50 2.8 is auto foussing very slowly. It takes about 1 sec to go from 1ft-inf. and 3s for a back-and-forth AF. I guess it needs oil somewhere. Can I do this myself (Im quite handy)? As its main use is landscapes, it is not the worst problem but it keeps irritating me so if you think it has to be done for a big amount of $$ -not by me then-, I will live with it then.
Oh, and Ive tried is with both 50D and 350D.
