It is probably the case that most photography today is done within families. We love to record the special events of family life, and especially the things that our children are involved in. So it is important to be prepared. This means taking our cameras with us most all of the time. We might even want more than one type of camera, a small one to keep with us all the time and a larger one for those times when we want more features, or a larger sensor. When my daughter was chosen to sing in an all-state chorus of course I wanted to be there with camera ready. But I did not want to carry a large DSLR, so I chose to take the Sony NEX 7, and a fast lens so that I would not need flash. I did not take a long lens to zoom in on just my daughter, but I did get a nice shot of the whole chorus, and thus preserved an important memory.
