越看越香，現在就等Z卡的原生鏡頭了。

希望將來有機會透過韌體更新，跟A1一樣用壓縮過的Raw檔，有利後期修圖
據dpreview的網友分析A1的30fps 不光是壓縮的Raw檔, 他是lossy Raw
雖然號稱14bit, 但dpreview網友分析過可用色深是13bit
A1 - 30fps RAWs are 13bit.
所以也同時解惑了為何A1明顯讀寫不及Z9, 但Z9卻沒有30fps Raw的選項, 因為目前Z9 Raw全是14bit.
目前三巨頭的Raw
A1: 30fps 14bit, 實為13bit
R3: 30fps 14bit, 畫素只有A1 / Z9一半左右
Z9: 20fps 14bit, 所有Raw檔都是14bit

Apparently during the Sony A&Q it was said that the A1 supports 14 bit only up to 20fps
Sony官網對於A7R4就有提到畫質的限制
Sony ILCE-7RM4 α7RIV File Format (still image)
RAW images recorded with this camera have a resolution of 14 bits per pixel. However, resolution is limited to 12 bits in the following shooting modes:
[Long Exposure NR]
[BULB]
[Cont. Shooting] when [RAW File Type] is set to [Compressed]
但是Sony官網對A1的畫質只有說Raw是14 bit
Sony ILCE-1 α1 Image Quality Settings: File Format (still image)

這網頁就差了A1沒資料
其他SONY機型都有
也許以後會更新

這裡的疑惑就是在於該網頁整理都是從各自的手冊中擷取, 所以很明顯是完全避掉A1
以上一代旗艦A9 II 為例, 一樣都會說明以compressed Raw連拍 = 12 bits
ILCE-9M2 α9II File Format (still image)
RAW images recorded with this camera have a resolution of 14 bits per pixel. However, resolution is limited to 12 bits in the following shooting modes:
[Long Exposure NR]
[BULB]
[Cont. Shooting] when [RAW File Type] is set to [Compressed]
Z9的手冊也同樣只提到Raw都是14 bit, 但目前還沒看到lossless Raw和HE Raw畫質上的差異比較
