My current setup is a K5 with a DA15 (landscape and creative), DA35 macro (walkaround), D FA100 WR (portrait and macro, some landscape.)
Recently I was volunteered to be the official photographer for my son's Cub Scout pack. (Hey, you have a camera ...)
I find that the 100mm seems to be the right focal length for taking candids and performances (talent shows, etc.). My frustration is that if I misfocus, I have to wait for the lens to rack through the entire focal length before I can start shooting again.
Did I mention that some of these kids are gymnasts? Spontaneous backflips, etc?
So I *think* I'm looking for something that can autofocus quickly, can recover from mis-focusing fast.
Yes, I know all about pre-focusing and manually focusing. I just can't react that fast.
So what's a good lens? Like I said, the 100mm range seems to be about the right length, but I'm sure I could make do with a slightly longer FL.
Oh, and one other thing: price is an object. I'm looking for the best for the least amount of money.
