Input:
I bought this lens to use as a fast portrait lens on my 6 year old daughter who never holds still. I was looking forward to shooting wide open, hand-held, no flash. Although I have a D80, I was initially having a focusing problem at f/2.2. I was actually thinking of returning this, since everyone has always commented on how sharp this lens is. By stopping it down to 3.2 and shooting at a faster shutter speed (1/600 & up), I seemed to have solved the problem. For me, I do find it hard to pinpoint the shallow focus of the lens when wide open especially when the subject matter will not hold still. But for the money, when it is focused correctly, it is very sharp.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: B: positive
