A7s 的sensitivity 真係好高

[HK.Raymond.Tse]

Very good as super sensitive wide field finder.

Not sure whether there is any low pass filter. Better to modify to remove loss pass filler and to cool it to reduce the serious chromatic noises.

A7s 真系好敏感，不過唔改機，紅色都重系差 d

請問師兄覺得用 a7s 作深空攝影適合嗎? 坊間有傳長曝熱噪點嚴重，師兄又點睇呢? 謝謝

1. 適合，不過無改機紅色會差d
2. 做左 dark frame /calibration 完全唔覺有問題
