What is a "fast" lens?

A lens with a specially lubricated focusing ring

A lens with a spring-loaded zoom

A lens with a relatively wide aperture, allowing for faster shutter speeds

A lens that is aerodynamically smooth

Correct! Wrong!

What focal length would be considered "normal" on a full frame or 35mm film camera?

70mm-200mm

50mm

200mm-500mm

10mm-24mm

Correct! Wrong!

Which of these focal lengths would be found on a "zoom" lens?

12mm-35mm

35mm

135mm

85mm

Correct! Wrong!

Why would someone want a lens with a silent focusing mechanism?

They have photographer's misophonia

To prevent unwanted noise in video

To avoid scaring sleeping babies

Secret spy stuff

Correct! Wrong!

To what does the "fisheye effect" refer?

When your eye has trouble adjusting after you stop looking through the viewfinder

Distortion in ultra-wide-angle photography making the photo look like it's bulging

A cold, slimy feeling from staring too long

Developing an "eye" for taking great pictures of fish

Correct! Wrong!

What makes a lens a "macro" lens?

It can focus while being physically close enough to the subject to reproduce it on the sensor/film at life size or greater

It's REALLY big

It's REALLY wide

It can run automatic zooming/focusing commands

Correct! Wrong!

How can a lens help you get less blurry pictures?

Holding up some of its own weight for a change

Predictive focusing

Whispering reassurances to make you less nervous

Utilizing internal motors and gyros to shift components to counteract camera shake

Correct! Wrong!

What does "tilt-shift" capability enable you to do?

"Tilt" and "shift" the slice of your image which is in focus (so it doesn't have to be directly perpendicular to the sensor/film)

View your camera's screen from any angle

Fold up your lens so it's ultra-portable

Show off a wacky lens that your friends have never heard of

Correct! Wrong!

To what does the focal length of a lens refer?

The minimum distance you must be from a subject to focus properly

The length of the lens in your camera bag

The maximum amount of time it can hold focus

The distance between the internal point of light convergence and the sensor/film, measured in millimeters (the larger the number, the greater the magnification)

Correct! Wrong!

What does the f-number of a lens actually mean?

Fantastic-ness; the best lenses are all f-number ONE!

It's just a number you have to learn; someone had to come up with something, right?

The ratio of the focal length of the lens to the diameter of the aperture (thus, wider apertures result in lower denominators in the ratio)
