Project Focal lengths
Exercise – Focal lengths (Zoom lens)
This exercise has helped me to appreciate the simplest effect of changing lenses, from one focal length to another, which is the amount of view i can take in. I needed to find a view which was open and had some detail in the distance, see my choice below of the estuary where i live, which i thought would be perfect and show the results very clearly. I have taken a a sequence of photographs all aimed in the same direction but with different focal lengths.
The images below were taken at 1/400 f22
24mm lens – telephoto
50mm lens – standard/normal
105mm lens – wide angle
From my shots above we can see that as the focal length gets longer, the angle of view closes in.
