Do you know the difference between a 50mm lens and a 500mm lens?
Look at the two photos - they were both taken from the same place - the left hand photos was taken with a 24mm wide angle lens, whilst the right hand photo was taken with a 400mm telephoto lens. The wide angle lens allowed me to get the entire room in one photo whilst the 400mm lens allowed me to zoom in on a detail some distance away.
Fisheye - 7~16mm are specialized and extremely wide-angle lenses that can produce circular, convex, or oval images by distorting the perspective and creating a 180° image.
Ultra-wide angle - 14-24mm give dramatic results, often exaggerating perspective to such a degree the photo looks unnatural and at times disturbing.
Wide angle - 24-35mm: are wide enough to show a lot of context, without your image looking unnatural. They are the natural choice for landscape and group portraits.
Standard / Normal - 40-75mm: A standard lens is estimated to be 50mm for a full-frame DSLR, which gives natural looking photos. They have a fixed focal length (50mm, 85mm, 100mm), and reproduce fairly accurately what the human eye sees.
Mild telephoto - 85-105mm: Great for portraits; long enough to create separation from the background but short enough to be close enough to your subject to interact and communicate.
Medium telephoto - 120-300mm: These lenses are useful for most photographers, and most genres.
Long telephoto - 300-800mm: Useful for wildlife and sports photographers, who stay quite a distance from their subject. They are expensive and complex lenses.
Zoom These lenses have variable focal lengths, sometimes ranging between a wide-angle and a telephoto (e.g. 24 to 300mm) giving you much versatility for composition. However, because of way these lenses are constructed, they have a limited ability to open up and allow in light, so unless you pay a fortune you will be limited with your aperture range.
Macro lenses Used for close-up or macro photography, they range in focal lengths between 50-200mm, and can obtain razor-sharp focus within the macro focus distance. They do however lose their ability for sharp focus at other distances.
Tilt-Shift These enable you alter the perspective of an image so the parallel lines of a building don’t converge, thus eliminating the distorting quality of the lens. They also enable you to selectively focus an image; where only specific portions of the image are in focus and out of focus within the same plane.
