Hi there, I know that it has already been debated, but need some tips. I just bought this lens used and will arrive tomorrow. I bought it because I needed a zoom with that focal range. Read it is not very sharp. Now that it has been used for a long time by members of this forum can anyone give me tips to get the best out of it. I don't use PP and tripod. and don't want to start now if possible. I think that sometimes I may use it in low ligh situations like Churches ecc. Thanks.
