Camera And Lens..

What is camera lenses..?

A camera lens is an optical device, often made of glass, that directs light into a camera and focuses it onto the sensor or film. It acts as the "eye" of the camera, capturing and shaping the image. 

Basic Parts Of a Camera ...

A camera captures images using light. Its basic parts include a "lens" (to gather light), "aperture"(to control light), "shutter"(to time light), and "sensor" (to record the image). The 'viewfinder" helps you see the picture before taking it.

Inside a "DSLR camera", a "mirror" and "viewfinder system" help the photographer see the image before capturing it.

1. Viewfinder– Where you look to see the picture.  

2. Pentaprism– Flips the image for correct viewing.  

3. Focusing screen– Shows the sharp image.  

4. Condenser lens – Helps light reach the screen.  

5. Color/IR filter – Removes unwanted light.  

6. Digital sensor – Captures the photo.  

7. Shutter– Opens to let light in.  

8. Display – Shows photos and settings.  

9. Electronics – Controls camera functions.  

10. Autofocus system – Focuses the image.  

11. Reflex mirror– Reflects image to viewfinder.  

12. Focusing elements– Adjust sharpness. 

13. Aperture – Controls light amount.  

14. Zoom elements – Zooms in and out.  

15. Front lens – Gathers light.  

16. Batteries – Power the camera.

The  3  Basic Camera Setting that Control Light ....

1. Aperture

 Controls how much light enters through the lens.  

2. Shutter Speed 

Controls how long the light hits the sensor.  

3. ISO

Controls the sensor’s sensitivity to light.

Camera Lenses ....

A "camera lens" is the part of a camera that focuses light onto the sensor to create a clear image.

Camera Lenses Types...

1. Standard Prime Lens

Fixed focal length; gives natural-looking images, good for everyday use.  

2. Zoom Lens

 Variable focal length; lets you zoom in and out without changing lenses.  

3. Fisheye Lens

 Ultra-wide angle; creates strong curved distortion, like a bubble view.  

4. Wide-Angle Lens

 Captures more of the scene; great for landscapes and tight spaces.  

5. Telephoto Lens 

Brings distant subjects closer; ideal for wildlife or sports. 

6. Macro Lens 

Designed for close-up shots; captures fine details of small subjects.

Different  Type Of Camera ...

1. Compact Camera (Point and Shoot)

Compact cameras are small, lightweight, and very easy to use. They are designed for automatic operation, meaning the camera chooses the best settings for you. These are perfect for beginners and casual users who just want to take quick photos without worrying about technical details. They usually have a built-in lens and a small sensor, which makes them more portable but limits image quality, especially in low light. Ideal for vacations, family events, and everyday photography.

2. Action Camera 

Action cameras are tiny, durable, and built to withstand extreme conditions. They are waterproof, shockproof, and often come with mounting accessories, making them popular for sports, travel, and outdoor adventures. The most well-known brand is GoPro. They typically have wide-angle lenses to capture more of the scene and can shoot high-resolution video (like 4K) with slow-motion options. They’re great for capturing fast movement and unique angles.

3. DSLR Camera  (Digital Single Lens Reflex)

DSLR cameras use a mirror system that reflects light through the lens into an optical viewfinder, allowing you to see exactly what the lens sees. When you press the shutter, the mirror flips up, and the light hits the digital sensor. DSLRs support interchangeable lenses, giving you flexibility for different photography styles—portraits, landscapes, sports, etc. They have larger sensors, which provide high image quality and better performance in low light. DSLRs are widely used by professionals and serious hobbyists.

4. Mirrorless Camera

Mirrorless cameras do not use a mirror like DSLRs. Instead, light passes directly through the lens to the image sensor, and the view is shown on an electronic screen or viewfinder. This design makes them smaller and lighter than DSLRs. They also support interchangeable lenses and offer high-quality images and video. Over time, mirrorless cameras have become more advanced, with faster autofocus and better video capabilities, making them a popular choice for both photography and videography.
