Exercise nine: Focal lengths

The exercise represented an opportunity to find a scene that I could take a wider shot of, and gradually increase the focal length to get a close up of a subject.

This was another opportunistic shot and as such I only had my 55-200mm lens with me.

55mm, 1/200 secs at f/20, ISO 400
60mm, 1/200 secs at f/20, ISO 400
80mm, 1/200 secs at f/20, ISO 400
100mm, 1/200 secs at f/20, ISO 400
130mm, 1/200 secs at f/200, ISO 400
150mm, 1/200 secs at f/200, ISO 400
200mm, 1/200 secs at f/20, ISO 400
In the first shot it's possible to make out that people are surrounding the stone by without understanding a great deal else with any accuracy. By the time we reach the closest shot, 200mm, you can make out the number of people, their positions and the colours of their clothing.

55mm, 1/200 secs at f/20, ISO 400
This is a magnified shot of the first image and, although the people in shot have changes positions slightly, it's pretty much the same shot.

This is something that I didn't expect. I'd assumed that that moving from 55mm to 200mm would have had some affect.
