This document discusses different types of camera lenses. It begins by defining what a camera lens is and providing a brief history of lens development. It then describes the four main types of lenses: normal lenses which have little magnification and a wide aperture; wide angle lenses which allow more of a scene to be captured; telephoto lenses which allow subjects to be photographed from a distance and have little depth of field; and zoom lenses which have a variable focal length, requiring fewer lenses but typically having smaller maximum apertures.

3. What is camera lens?
• A camera lens (also known as
photographic lens or photographic objective)
is an optical lens or assembly of lenses used in
conjunction with a camera body and
mechanism to make images of objects either
on photographic film or on other media
capable of storing an image chemically or
electronically.

4. History
• The invention of the camera in the early 19th
century led to an array of lens designs intended
for photography. The problems of photographic
lens design, creating a lens for a task that would
cover a large, flat image plane, were well known
even before the invention of photography due to
the development of lenses to work with the focal
plane of the camera obscura.

5. There are four types of lenses
And they are:-
• Normal
• Wide angle
• Telephoto
• Zoom

6. 1.Normal Lens
• This lens is called “normal” because it has little if
any magnification compared to your eye
• This is the cheapest, and most often used lens
• It offers a very wide aperture (ie.- f1.8, f1.7, or
even f1.4
• This is the lens we have used up until this point
on the cameras in this class
• Has a focal length of 50mm

8. 2.Wide angle Lens
• Offers an increased angle of view.
• Allows you to take photos in an area
where space is limited.
• Offer a very good depth of field.
• Interesting effects,exaggerated sense of
perspective.
• Available in both rectilinear and fisheye
• Has a focal length of less than 50mm
(usually less than 35mm)

9. Wide angle Lens

10. Telephoto Lens
• These lens range between 70 – 1000mm!
• They tend to give your photo a “flat” look
• You must use a very fast shutter speed with these
lenses over 200mm.
• These offer little depth of field.
• Allow you to get a photo without getting
too close to your subject.
• Larger lenses need a stand for the lens,
not the camera.

11. Telephoto Lens

12. Zoom Lens
• This lens has variable focal lengths
• Fewer lenses to carry
• You can do “cool” special effects with them.
• They tend not to have very wide maximum
apertures (ie f5.6).
