I originally got my telephoto lens to take close up pictures of wildlife without scaring my subjects off. However, I've noticed that it also allows me to take pictures of my family without them knowing I'm taking a picture of them. I have been pleased with the results. I took this picture of my kids at the bus stop on the same foggy morning as the previous post. 210 mm, ISO 200, F/13, 1/50 sec exposure.
