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. HOW CAMERA LENS WORKES:
Camera Lenses work similarly to the human
eye and allow you to control the amount of
light that enters your camera. Inside each
lens is a series of convex and concave optical
elements that work together to bend light and
refract it into a single sharp focal point. And
uses of camera lens has some parts:
Diaphragm
Focusing Ring
Diaphragm Adjusting Ring
Shutter

5. DIAPHRAGM:
A diaphragm is a camera component within a
lens comprised of overlapping metal blades
(the iris) that open and close to change the
size of the opening (they allow different levels
of light to pass through to the sensor - thus
controlling the aperture (or f-number) and
depth of field of an image and the aperture
hole of the lens.

6. FOCUSING RING:
This is a section of the lens that rotates to
allow the photographer to focus the image.
On automatic cameras, this ring is moved
by a small motor within the lens whenever
you press the shutter release button
halfway down. For manual focus, you will
turn the ring until the image comes into
focus.

7. SHUTTER:
Shutter in photography, device through
which the lens aperture of a camera is
opened to admit light and thus expose the
film (or the electronic image sensor of a
digital camera). Adjustable shutters control
exposure time, or the length of time during
which light is admitted.

9. THE VARIOUS TYPES OF CAMERA
LENS:
NORMAL LENS
ZOOM LENS
TELEPHOTO LENS
MACRO LENS
WIDE ANGLE LENS
ULTRA WIDE ANGLE LENS
9
10. 1. NORMAL LENS:
Normal standard lens Key Advantages Suitable
for lowlight photography Light weight device
Higher quality image production Good
beginner’s choice.
10
2. ZOOM LENS:
Key Advantages A photographer can take
different focal length shots while maintaining
the same shooting position The lens is suitable
for when changing lenses is difficult. For
example, a wedding, in dusty/sandy/wet
locations.
11. 3. Telephoto Lens:
Photographers do not need to move around; they
can take shots while maintaining the same position
Rids unwanted details by creating a blur in the
background surrounding images but produces a high-
quality clear picture.
11
4. Macro Lens
Excellent image sharpness and quality Close-
focusing means small subjects are rendered with
high level of detail Also good as portrait lenses
Good for product photography in the studio or for
small wildlife on location.
12. 5.Wide Angle Lens:
Pictures contain more depth and contextual
information due to wider field of view . It provides a
greater depth of field for sharper front-to-back images
Light weight lenses in smaller packages make them
easier to carry Great for a wide range of subjects.
12
6.Ultra- Wide Angle:
It is useful for scientific photography, to
determine solar radiation and observe plant
canopy geometry Wide field of view makes
them great for landscapes Perfect for abstract
photography Useful for astrophotography.
