I just read in one of your answers (OP..) that you might be thinking of buying a da50 for use of AF.
If so, i'd suggest to rather save up for a 2nd hand da70. very nice lens on apsc & relative affordable, and especially: an additional focal beyond what you already have!
Personally i find 50 a bit too short. With the da70, i can still keep a comfortable distance if i want something rather up close to the subject.
All this said though: i'd first go with the advice of others: try the 50 you have now and focus on lighting your subject & stuff like that..
