NAB2014-Sony 於 NAB2014 發表 α7s 全片幅單眼相機，支援 4K 影像輸出
延用α7的機身設計，替換了感度更高的全片幅感光元件，這也是為什麼稱之為 α7s 的緣故加入 HDMI 4K 影像輸出，並支援 S-Log2 Gamma 曲線，能讓拍攝畫面擁有更多的層次表現！錄影模式下 ISO 範圍可從 200 到 102400
支援外部擴充 XLR 套件

SONY 這麼快就回應GH4了，果然有競爭才有進步
還端出這超高ISO的好菜，拍照也很受用
用A7機身是小巧，就那電池相當不給力（同NEX-5）
4K 錄影時是只能用FE鏡頭？還是有裁切些到super 35，E鏡頭也可用？:-? 應該是支援4K無損輸出，需搭配外加的影像擷取裝置才能錄影，機身內的錄影還是只到1080P 60P 50Mbps。 It records 1080p internally in XAVC-S format at 50Mbit but the big news is the support for full 4K output via HDMI to an external recorder.

比照GH4內建XAVC 4K錄影，不是件難事吧 本文章最後由 XepherZenith 於 2014-4-6 21:54 編輯
看到這新聞就想到今天用A7R錄影時錄到一半居然出現"機身過熱,請關機降溫後再開".
錄到一半居然強制關機實在有點#@$@#%....而且環境溫度不到30度...
不過A7S是專門錄影的機子,希望不有過熱的問題.話說回來,ISO 409600!!真是嚇人的高!!

這厲害了~
但是要搭配什麼儲存裝備才能錄製4K ??
暫未公佈價格是等消費者反應才定價嗎??

前陣子一忙就忘了po，其實 a7S 在上週 DV-Asia 舉辦的 Post-NAB 就正式開放預購了
台幣定價為單機身 69,980 (含稅)
預購期間 (7/6以前) 有加贈市價 9,980 的 VG-C1EM 垂直手把 (手把可裝填兩顆電池)
ps: 不過剛看了官方網站，顯示目前已缺貨。有需要的朋友可能得跑一趟實體通路問問了
