Firstly I needed to find the standard focal length for my camera, the distance at which the viewfinder most closely matches the scene as viewed with the naked eye. After a bit of playing around I found this to be approx 100mm which sounded wrong but I double checked and the result was the same.
Standard - 100mm |
This is the photo taken at the standard focal length. When printed out I found that it matched the scene when it was held roughly 67cm away from me.
Wide angle - 28mm |
This is the view from the same position when the lens is set to 28mm. When printed and held out in front of me it matched the scene at only 16cm away, a lot closer than the standard setting.
Telephoto - 400mm |
For this photo the full telephoto was used @ 400mm. With all three photos the large red ball was the focal point. Again, this photo was printed onto A4 and held in front of me. Using my beautiful assistant Karen I found the distance this time was approx 230cm
