Bringing some lenses with my son around sometimes gave me trouble. I had to watched out him, so I could not used lenses I brought. So I think I need zoom lens.
Biggest aperture 4, so I thought  it must be used in clear day to get good image. But I tried @ 5pm... Samples here taken in evening, with high ISO. Not bad I guess.
