Camera lenses come in a variety of types to suit different photographic needs. The major types of digital camera lenses are standard lenses, macro lenses, telephoto lenses, wide angle lenses, specialist lenses, and kit lenses. Standard lenses have a mid-range focal length similar to human vision. Macro lenses are designed for close-up photography while telephoto lenses provide magnification for distant subjects. Wide angle lenses capture a wider field of view and fisheye lenses use strong distortion. Specialist lenses create specific effects while kit lenses are basic lenses bundled with entry-level cameras. The type of lens used depends on the subject and photographic goals.

1. CAMERA LENS

2. WHAT ARE 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.

3. TYPES OF LENS
There are 6 major types of Digital Camera Lens
1.Standard Lens
2.Macro Lens
3.Telephoto Lens
4.Wide angle lens
5.Specialist Lens
6.Kit Lens

4. STANDARD LENS
◦ A Standard lens is one with a mid-range focal
length, typically around 50mm.
◦ They have an angle of view which is roughly
the same as the angle that the human eye can
comfortably view.
◦ Standard camera lenses usually have a fixed
focal length and wide aperture.
◦ They are popular for a wide range of
photography subjects, including landscapes,
portraits, and candid shots.

5. MACRO LENS
◦ A Macro lens is one designed especially for
close-up photography.
◦ They have a different internal construction
from normal lenses which gives them very
good sharpness and contrast.
◦ Macro lenses are useful for photographing
any subject at very close range.
◦ Typical subjects include insects, animals, and
plants.
◦ They are also popular for taking extremely
detailed photos of everyday objects.

6. TELEPHOTO LENS
◦ A Telephoto lens has a long focal length and
provides a high level of magnification.
◦ Allowing you to photograph subjects at a
moderate to far distance.
◦ They tend to be bigger and heavier than other
types of lens.
◦ Telephoto lenses are popular for any type of
photography where you can't get near to the
subject, including wildlife and sports events.
◦ They are also commonly used in portrait
photography, where a moderate telephoto lens
will provide a natural, undistorted perspective.

7. WIDE ANGLE LENS
◦ A Wide angle lens is one with a short focal
length.
◦ They provide an angle of view beyond that of a
standard lens, allowing them to capture more
of the scene in a single shot.
◦ Extreme wide angle lenses are known as
Fisheye len.
◦ Wide angle lenses are useful for
photographing landscapes, cramped interiors,
and other subjects which won't fit into a normal
lens's field of view.
◦ Fisheye lenses take this even further, and are
popular for photographing action sports like
skateboarding and surfing, where their
inherent distortion gives photos a dynamic feel.

8. SPECIALIST LENS
◦ Finally, there are a number of specialist camera lenses which cater for less
common photography needs.
◦ These include Tilt and Shift lenses for perspective control.
◦ Soft-focus lenses for portrait photography.
◦ Infrared lenses for capturing light outside the normal spectrum.
◦ A specialist lens is used to produce some sort of special or creative effect, and
so they have limited use in general photography.
◦ However, they can be very useful if you need to photograph a particular
subject in a particular way.

9. KIT LENS
◦ Many entry-level SLRs come bundled with one or two lenses.
◦ Often called "Starter" or "Kit" lenses. These are good for
getting you up and running quickly but they are generally very
cheap, slow lenses with poor image quality.
◦ A kit lens is great for getting to grips with your camera and
figuring out what focal lengths you like using, but you should
consider replacing it when your budget allows.

10. CONCLUSION
◦ There are many things that determine the quality of your photography, and
one of the most important is the lenses you use.
◦ A good camera lens will capture sharp photos with plenty of detail and
contrast, while a poor one can leave your images looking dull and blurry.
◦ When shopping for lenses, it's important to consider the types of subject you
intend to shoot, the likely lighting conditions, and of course your budget.
◦ There is no single lens that is perfect for every situation, so you'll need to
balance the pros and cons of the various options and pick the best
compromise.
