Fion says: and then something like 18-70 mm f 3.5-5.6 lens Fion says: what do they mean? Fion says: do i need to know? :p CYRIS Mo Chit B says: 要架, 好重要添, 玩DSLR另一個目的係可以換鏡頭 CYRIS Mo Chit B says: 18-70即係ZOOM鏡, 好似DC個D咁啦, 個mm數越細真係越WIDE, 越大越TELE CYRIS Mo Chit B says: f數係光圈值, 個數字越細, 即光圈越大 CYRIS Mo Chit B says: 因為呢個f數係分母黎的 Fion says: 光圈越大越好? CYRIS Mo Chit B says: 光圈越大, 景深越淺, 會做到D對後散景FEEL CYRIS Mo Chit B says: 越大, 光進入鏡頭會越多, 咁個快門就可以快D, 第一, 會無咁易手震, 第二, 可以易D影到快速移動物, 例如: BB, 狗仔, 雀, 車 Fion says: 快速移動物, 例如: BB.... hahaha.... CYRIS Mo Chit B says: D狗仔, 貓仔, BB成鬼日郁來郁去 CYRIS Mo Chit B says: 好難影架...
"快速移動物" made me LOL cos i thought my friend meant animals (動物) that move fast (快速移)... but after i stare at it for the 3rd time, i realize he meant things (物) that move fast (快速移動).........
