各位c hing 用乜嘢準則去選購合適嘅定焦鏡(焦距)呢？
係咪根據自己最常拍的焦距?

這兩枝有乜分別，點解35mm貴1K？成像邊枝好d？
nikon 35mm f2
nikon 50mm f1.8

35mm is wide angle lens

一支廣角鏡頭會比較貴，加上是f/2.0大光圈鏡頭，當然會更貴。

nikon 50mm f1.8

nikon 50mm f1.4

兩枝有乜分別

Anybody can post picture to compare?

f1.4 smaller depth of field than f1.8 when both open to the max aperature.

In general, a lens performs best when the aperature is stepped down 3 steps from the max. aperature, i.e. for f1.4, the best aperature is f4 (still a large aperature to allow taking photo in dim area), for f1.8, the best aperature is f4.5-f5.6
