By now you must be wondering what’s the point of this exercise?
Basically I wanted you to experience and understand that the zoom function in your camera has its limitatiom and drawbacks. The quality of your image is very much affected by how you use the zoom as the exercise in the illustration shows. There are many technical reasons why this is so (the 2 things that springs to mind is depth field and lens quality) but I will not cover it for the time being.
Just know that the lens and the zoom matters for the time being….
Knowledge of this will help you in the next lesson.
