LENSE VS DSLR The beauty of DSLR depends

LENSE VS DSLR The beauty of DSLR depends upon the LENSE two fundamentals for any Camera: focal length and sensor size Every lens is defined in millimetres (focal length of camera) This measurement is the distance between the sensor and the optical centre of the lens when the lens is focused on infinity

TYPES OF LENSES WIDE ANGLE: 28 mm or less, good for interiors and landscapes STANDARD: from 35 mm and 85 mm, good for general use and portraits TELEPHOTO: from 100 mm to 300 mm, good for sports, portraits and wildlife MACRO LENS: use for Close-ups ZOOM LENS: minimum 14 -24 mm and max 70 -200 mm focal length PRIME LENS: with fixed focal length (50 mm)

Wide Angle lenses : (28 mm) has a wide view. It allow us to fit a lot into an image Wide-angle lenses make the subject look big only when it is very close to the lens, but still take in a wide area of background Wide angle lenses have short focal lengths Wide-angle lenses are most commonly used for photographing landscapes and architecture, are great for documentary photography, although they are often also used for photographing large groups of people

WIDE ANGLE LENS

STANDARD LENSES Standard lenses- are great for portraits they give a pretty accurate image that’s natural looking and free from distortion Standard lenses are most commonly used for documentary and street photography The standard 50 mm lens is more or less equal to the sharp central field of view of human sight, A standard lens has a focal length range of 35 -70 mm. The most common standard lens is a fixed 50 mm lens

TELEPHOTO LENS Telephoto lenses like 80 mm or longer, will bring things closer to photographer They compress the background and foreground so that it’s hard to tell how far distances are between objects These Lenses are ideal when we can’t get close to the subject Telephoto lenses are traditionally used for sports and wildlife photography, but their essential function is to bring distant objects closer A telephoto lens the Canon EF 200 mm f/2 L IS USM

There a variety of SPECIALIST LENSES Some of the more common are: SUPER TELEPHOTO - These have a focal length of more than 300 mm, and are used by sports and wildlife photographers FISHEYE - These are on the edge of wide-angle lenses, and give a distorted view of the subject matter. The center of the image is magnified, and objects diminish in size in all directions around it.

PORTRAIT LENS The focal range between 80 -135 mm is nearly always used by portrait photographers. Fixed lenses at these lengths produce ideal framing for head and shoulders shots Medium Telephoto/Portrait Lens

MACRO LENS Macro lenses allow to get very close to the subject to produce images that are life size or larger. These lenses enable you to get in incredibly close to the subject Macro These lenses are able to focus closer to an object than normal lenses, offering a 1: 1 ratio. They are used for still-life photography of small objects

MACRO LENS Close up shots of flowers & other objects

ZOOM LENSE These lenses can have quite narrow ranges or quite long ones Typical focal length ranges are given as the minimum (14 -24 mm, 18 -55 mm) and maximum (70 -200 mm) focal length,

PRIME LENS A prime lens is a lens that has one focal length only. prime lenses are known for their image quality and speed (faster aperture) Common ones are 50 mm (known as a Standard lens), 85 mm, 35 mm and 300 mm. Their focal length is fixed They’re often considered 'fast', meaning that the apertures on them are large, like - f 2. 8, f 1. 4, even f 1. 2, are wonderful for taking pictures in low light
