NEX-5N full spectrum 無filter,機身轉黑白,直出。
好有興趣。
咁係唔係full spectrum 無filter,部機直出嘅色係黑白,還是要後制?

A7 ..nake sensor 唔知到影出黎,效果似唔似MM呢。。。:lol

回番hothmonkey 同 頭文字L 兄, full spectrum = nake sensor 影出黎效果同M8 一樣,影多左紅外線同sharp 左. 想影到MM 果種黑白就要連bayer filter 都去除,不過bayer filter 只係一層coating, 而去除過程極影整壞sensor. 其本上冇人會接番後整.我見過有鬼佬整過,不過都整壞左幾個sensor,而且去除得唔完整. 所以要冇bayer filter 既sensor 只可以同sonsor 廠訂製.

咁請教下,有無話用幾厚的IR-cut filter最optimize 呢? 例如:由21mm/3.4 super angulon / 21 super elmar 起計算。。。我見外國有全拆A7玩28 summicron M, 基本上同M240 出的相係99.95%近...:lol. 即28mm打上,以經無難度 ?

1mm 厚已經係最好. 如果用B+W / leica   ir-cut 就28mm 或以上已冇問題

其實有無人試過sigma fovoen sensor改 full spectrum 呢? 咁咪冇 bayer filter 囉! {:2_37:}

fovoen sensor改完 full spectrum都仲係有三層bayer filter,佢有三層 sensor, 每層一塊bayer filter{:4_96:}

請問Fuji非傳統Bayer filter 排列,改full spectrum會有何不同?

Thanks Alexty2 for helping out with the removal of the IR filter from my D200.
Highly recommend him for his duty conscientiousness and quality service.
Here are a few shots from my "stripped" D200 coupled with a cheap f1.8 AFS 35mm DX Nikkor.
