雖然Sony已經發表了其EVIL相機 - NEX-3 / NEX-5並使用了全新的E-mount (有別於Alpha系列的A-mount)，但其他相機大廠如Nikon、Canon等始終到目前為止也沒有推出類似的產品，但現在Nikon的Fans終於有望看見Nikon的全新EVIL相機了！

當然Nikon方面沒有正式公佈，但外國一些網站已經發現了Nikon正在注冊有關EVIL的專利，事關專利申請圖樣顯示了EVIL的大部份特徵，包括電子觀景器，但有一點十分有趣的是Nikon的EVIL竟然包含了一面反光鏡！從以下的專利申請圖看來，那面反光鏡並不是單反常有的棱鏡，而是電子觀景器的一部份。Nikon是想利用反光鏡解決電子觀景器訊號滯後的問題嗎？

專利圖也有另一個特點 - Mount保護裝置，應該是當鏡頭除下時可以自動蓋上以保護機身內部。以下是Nikon的專利申請書英文譯本：

Patent Publication No.2010-161569

• published 2010/07/22
• filled 2009/01/07

• At the time of lens desorption, useless thing invades the camera inside.

  • It possesses a sensor detecting lens desorption.
  • At the time of lens desorption, protective cover is pushed inside.

The embodiment of the patent

另一段文字也可看出那個Mount的保護裝置：

“Heretofore, lens-interchangeable type cameras provided with a barrier that, in a state in which an interchangeable lens is not attached, closes off an aperture that is provided in a casing for allowing the passage of object light has been known”

從以上文件看來，Nikon確實是要做一部帶有反光鏡的EVIL相機(注：一般EVIL是沒有反光鏡的)！Nikon的EVIL相機，真的令一眾Nikon fans期待！
