1. What is crop factor? How does it affect the image shot with different lenses?
2. What is a "normal" lens? What is a wide angle lens? What is a telephoto lens? How do they affect the image that is shot?
Crop factor refers to the "magnitude of the crop as compared to a 35mm still horizontal standard." Different size sensors can cause the image to capture a smaller cropped image in comparison to a full frame shot. This field of view that is available to be seen through the camera is also determined by the focal length of the lens. A "normal" lens refers to lenses with focal length that replicates how humans normally see with their eyes. What is considered to be a "normal" lens depends on the way it is displayed and the sensor size. For example, if the footage is intended for the big screen, the diagonal line's length is twice the average camera. For full frame average cameras for normal screens, 43mm will create a "normal" view, while a smaller sensor size will require diagonals ranging from 26mm to 22.5mm if on a micro 4/3rds camera. Other lenses include telephoto lenses which zooms in as a result of a higher crop factor and wide-angle lenses which captures a larger field of view
