Focal Length and Angle of View

Exercise 1

The first two pictures were taken with an 18mm to 55mm lens, and it was taken at 35mm as this picture appears equal with my eye and through the viewfinder.

I had to hold this picture at a distance of roughly 16".

The Second picture was at 18mm as this is my widest angle.

I had to hold this picture at a distance of roughly 10".

This third picture was taken with my 75mm to 300mm lens at 300mm as this is my biggest zoom.

I had to hold this picture at a distance of roughly 64"
