Input:
Also good for portraits when background is good distance from subject.  Not good in low light but that is to be expected from f4 lens. However, with a little work in adjusting exposure, it can be useful in some low light situations.  Image quality is wonderful.  I think I like it better than the f2.8 version mainly because of the IS, lighter weight, while still having very good IQ.  Certainly better than the 24-105 f4 in, again, IQ and weight.
