What is focal length?

• The distance between you and the subject being photographed

• The distance between the lens and the camera's digital sensor

• The amount of stuff you can see in an image

When you see 1: # on a lens, what is the # that is being referred to?

• Distance

• ISO

• Aperture

• Shutter speed

Why might there be two aperture numbers?

• The lens has a variable aperture

• It is a bigger lens

What would be considered a wide angle lens? (Must pick 2)

• Anything more than 35 mm

• Light lenses

• slow lenses

A lens with a focal length greater than 70 mm

• wide angle lens

• ultra wide angle lens

• telephoto lens

• super lens

How would you describe field of view? (Must pick 2)

• Your distance from the subject

• The amount of stuff you can fit in the frame

• The width of the frame

• It's when the background is really clear

What's a downside to using an ultrawide angle lens?

• Too little light coming into the frame

• Too much light coming into the lens

• Darkening around the edges of the frame

• Distortion around the edges of the frame

What is a lens that has a focal length of less than 16 mm?
