Focal Length Experimentation
- Focal Lenth - the distance between the centre of a lens or the curved mirror and its focus.
- Field of View - What can be seen. This is determined by the angle of view from the lens to the scene. It can be measured either horizontally or vertically.
- Wide Angle - Involves having a short focal length and therefore a field covering a wide angle.
- Standard Lens - a camera lens with a focal length which is around equal to the diagonal of the negative. This will give a field of view which is similar to real life for the naked eye. In 35mm photography, lenses with a focal length of 50mm are seen as normal as they work without reducing or magnifying.
- Telephoto - a lens with a longer focal length than standard, gives a narrow field of view and a magnified final image.
Good definitions here but I think you should add the focal length numbers so that this is fixed in your mind and that you show a better understanding e.g. standard focal length lens -= 50 mm telephoto = e.g. 70 - 500mm and so on... you should find this information based on your internet research, etc.
