我打算買部單反機學攝影
但我見到鏡頭有好多種, 未完全清楚所有類別的用途,
以下就是我想知道的:
Zoom Len 同埋 Telephoto Len 有甚麼分別 (大概兩種都是用來影遠處的事物吧, 但不知有何分別)?
Wide Len 同埋 Ultra wide 有甚麼用途?
Teleohoto Zoom Len 同埋 Wide Zoom Len 又是有甚麼用途?
Standard Len 係唔係指只有恒定光圈和焦距的鏡頭?
Thanks!

有時係分別在個廠鍾意點叫暨姐。Zoom 可以拉近拉遠， Tele可能只影某一個範圍內暨野！wide係用呢影大範圍或角度暨野。ultra wide 咪 ultra D 囉。standard 多數係最普通多用途暨鏡，如乜野18-55或18-70個類。大慨係咁上下啦呱。

鏡頭主要以焦距作為分類

14-20mm是Super wide/ultra wide超廣角鏡
24-35mm是Wide angle lenses廣角鏡
50mm是Standard Lenses 標準鏡
70-300mm是Tele lenses長焦距鏡
400-1200mm是Super Tele lenses超長焦距鏡
另外還有因功能不同而分類,
例如魚眼鏡Fish eye(可以拍攝到180度），
Marco Lenses微距鏡(可以拍攝細小的物件）
Zoom lenses變焦鏡是鏡頭焦距不是固定，例如28-70mm, 70-200mm等
Wide Zoom Lenses就是指變焦的焦距都是在廣角鏡內，例如16-35mm
Tele Zoom Lenses就是指變焦的焦距都是在長焦距鏡內，例如100-300mm

Zoom Len 同埋 Telephoto Len 有甚麼分別 (大概兩種都是用來影遠處的事物吧, 但不知有何分別)?
Zoom lens packs different focal length into 1 lens.
eg. FZ10 zoom lens covers from wide lens (35mm) to telephoto lens (420mm)

Wide Len 同埋 Ultra wide 有甚麼用途?
50mm lens viewing angle is almost the same as human eyes.
35mm lens cover wider viewing angle
18mm lens cover ultra wide viewing angle
The main characteristics of wide angle are :
Larger depth of field (larger sharp image area)
Perspective changed. (things close to the lens become larger, things far from the lens become even farther.)
Wide angle lens is suitable for landscape, building.
Ultra wide angle lens is used to exegerate the perspective.

Teleohoto Zoom Len 同埋 Wide Zoom Len 又是有甚麼用途?
Telephoto zoom lens has long focal length eg. 35mm - 420mm where as 420mm is telephoto lens.
Wide zoom lens has short focal length eg. 17mm - 55mm where as 17mm is wide.

Standard Len 係唔係指只有恒定光圈和焦距的鏡頭?
Usually 50mm is standard focal length lens which has perspective similar to human eyes.
Standard Kit lens is the lens that comes/sells with SLR camera body.

Happy shooting !
