Lens Operations and Controls Project


We got in groups of three, outlined what we were going to do and also made a video. We did a lot to our video and had to look up a lot of information. It was hard at times but we just asked for help. Our video turned out good. I was the editor of this project.

Terms and Concepts

  • Focal Length: the distance between the center of a lens or curved mirror and its focus.
  • Filters: is a camera accessory consisting of an optical filter that can be inserted into the optical path.
  • F-Stop: shutter speed regulates how long the film is exposed to light coming through the lens.
  • Lens speed: refers to the maximum aperture diameter, or minimum f-number, of a photographic lens.
  • Iris: a flat, colored, ring-shaped membrane behind the cornea of the eye, with an adjustable circular opening (pupil) in the center.
  • Zoom and Zoom Ratio: Determine how much or little of the scene you are photographing.
  • Manually: Work or done by hand or machine.
  • Automatically: Done of produced at if by machine.
  • Depth of Field: the distance between the nearest and the furthest objects the at give an image judged to be in focus in a camera.
  • Angle of View: seen through a lens for a given sensor-size. With a full-frame sensor a lens gives the same angle of view as it would on a 35mm film camera. With a smaller sensor, the angle of view becomes smaller.
  • Wide angle lens: Wide angle of view, seen a lot.
  • Image Stabilization: reduce blurring associated with the motion of a camera or other imaging device during exposure.
  • Longer lens: make distant objects appear magnified with magnification increasing as longer focal length lenses are used.

What I Learned

I learned about camera lenses and how it takes different photos. There are a few problems here and there like we didn’t know how to take a good photo with some lenses. Editing this project was harder than some of the others because it was the first time I had use the sound room.
