平時用緊C17-55影人,想買支50.4定焦

用50.4 F2.8
同C17-55 用50mm F2.8

成象有差幾遠
有無相睇下丫

50.4 點解仲要用2.8 呢？

[Obi-Wan]

EFS 17-55/2.8 is king of APS-C Canon Zoom, cannot even compare with 50mm F1.8 @2.8

Zoom is zoom, prime is prime.

用過c 及S記50.4及1755
真正要睇你影咩多
APSC機，50mm有點唔上唔落
S30.4／C35F2較好用，S85.4/C85.8實靚D
好簡單的測試方法，將你支1755set去50mm
試試一小時都唔變焦會否有問題
然後轉去30／35mm試試邊個好用D

再靚仲有紅圈
