Nikon M1 Body

Nikon may have done what we all want, which is use a real 54 x54mm square sensor with a resolution of 6,380 x 6,380 pixels.

Nikon最近可能完成了許多人朝思暮想的一個目標,那就是54X54mm 畫素高達4千萬的方形感光元件


This is fantastic; it's the same size as a mounted 2-1/4" transparency.

這是非常驚人的,因為這塊感測器的尺寸將介於2-1/4吋之間
(
翻得怪怪的,懶得找DR. Eye眼博士來潤飾了XD)

It may have the very slick ability to select horizontal or vertical crops as you shoot, much as I select 4:5 crops in my D3 using my Function button.

依照過去的技術,這塊感光元件將有著能從水平或垂直方向裁切成你想拍攝的片幅,以筆者來說最喜歡的則是裁切成4:5也就是D3DX格式,且這個裁切可以使用機身上的功能鍵設定來快速切換

This means you can shoot 6,380 x 6,380 square, or a vertical or horizontal with a 6,380 pixel long dimension and a 4,256 short dimension.

這代表著你可以拍攝6380 X 6380的正方形影像,或者可以水平或垂直方向抓6380的長度,寬度則可以只抓4256的維度來拍攝。

In these cases, the active sensor size is x 36 x 54mm, or the old, bogus 3:2 aspect ratio of 35mm film. It would have been far better to crop to 43 x 54mm, the professional 4:5 ratio. Nikon might get booed off stage at WPPI if people are math hacks like me and realize that Nikon chose the wrong crop.

在這些舉例上,具變動式的感測器大小可以式36 X 54 或是過去的綜橫比為3:2 35mm 底片。甚至是更好得43X54mm 所謂的4:5比例裁切。(僅部份翻譯)

You'll also have the ability to crop into the smaller 4,256 inner square, much as we can crop our FX cameras to DX.

This camera also can crop to FX (24 x 36), at 2,832 x 4,256 resolution, as well as a foolish 24 x 24mm square (2,832 x 2,832) pixels, and 27 x 27mm "Super Slide" 3,184 x 3,184 pixels.

當然,比照FX機可以裁切DX格式的技術,此次M1機種一樣可以僅中央裁切4256比例亦即FX格式裁切拍攝。這台機子有著可以裁切FX(24x36mm 2863x4256 1200萬畫素)的方案,然後還能裁切24x 24mm(方形的2832x2832 800萬畫素)或是27x27mm(Super Slide 3184 x 3184 1013萬畫素)

The crop factor at full aperture is 0.57, or the diagonal of the full 54x54mm sensor is 1.75x the diagonal of 24 x 36mm.

轉換焦段為乘以0.57,換句話說比照24 x 36片幅換算為54x54的話是乘以1.75

 

Lenses

Rumor has it that these are the lenses:

另外乳摸也提供了一些鏡頭訊息

AF-S MX Nikkor 24 f/4.0G

AF-S MX Nikkor 45 f/2.8G

AF-S MX Nikkor 85 f/2.8G

AF-S MX Nikkor 135 f/2.0G ED

AF-S MX Nikkor 200 f/2.8G ED

AF-S MX Nikkor 65-180 f/2.8G ED IF

 MX格式鏡頭,所以都要乘以0.75倍才是MX格式下正確的焦段

And here are the 35mm film (FX) equivalents, rated for the same diagonal felid-of-view:

這裡有一個表格,裡面列出FX格式為依據,各個片幅下轉換倍率後的鏡頭焦段

簡單解釋一下這個表格,最左邊各個焦段都是以FF鏡頭為標準的標示,而各個片幅的對角線寬列於第二行,第三行則是焦段轉換乘上的倍率。

24mm這個焦段來說,54x54則是相當於18mm超廣角。36x54mm則乘以0.67倍所以相當於16mm 依此類推。
