The lens that came with my camera has been stolen and I don't know which lens to buy to replace it. It was taken off of my camera, that was in it's bag, during a house move. Funnily enough the zoom lens, which was also in the bag, was left. Can you suggest a replacement lens for everyday use please. I mostly take photos of my grandchildren. I haven't claimed on my insurance as I believe it will cost less to replace than my excess. Any advice would be welcomed.
