曲面感光元件版 RX1 會是 Sony Alpha 發表會的重磅新品？

眼看相機市場上多數對手都踏進了全幅無反的領域，甚至開始威脅到 Sony 原先算是有點獨佔的領域。似乎是時候打開黑科技寶箱拿出些新東西了？沒錯，緊接要在明日登場的 Sony α（Alpha）新品，也許將並沒有那麼地「前所未見」（咦）。據傳，他們將可能端出多年前曾公開展示先進技術的曲面感光元件所打造的產品。繼續閱讀傳曲面感光元件版 RX1 會是 Sony Alpha 發表會的重磅新品報導內文。

曲面感光元件版 RX1 會是 Sony Alpha 發表會的重磅新品？

做為 Alpha 全幅無反時代的前奏，2012 年在 NEX-6 與 α99 的發表會尾聲，Sony 重磅推出了搭載全幅感光元件的固定式鏡頭便攜型 DC，Sony RX1。到了 2021 年，現在似乎也傳出 Sony 可能再用這樣的傳奇產品系列開啟「前所未見（The one never seen）」的 Alpha 數位相機新篇章。

根據 Sony Alpha Rumors 的消息，採用曲面全幅感光元件且光圈更大的 RX 系列新品（RX2？RX1R III？）很可能將會在這次的 Alpha 發表會上發表 — 雖然 DC 在可交換鏡頭產品的 Alpha 發表會上發表有點奇怪，但仔細想想 RX1 其實當時也算是個不速之客囉。

假若 RX 系列採用曲面感光元件規格的消息成真，這可能代表未來 Alpha 可交換鏡式無反相機，也將會像是 RX1 之後推出 A7 系列那樣，緊接著推出搭載相同感光元件的產品。

相對於以往的平面式感光元件，根據以往的技術資訊，曲面感光元件因為在四個角落都有透過陶瓷機構來支撐來達到更向前彎曲的型態，將可根本上有效解決相機系統光學上以往難解的邊緣失光問題。帶來的好處，普遍認為應該會讓鏡頭的設計更簡單，也意味著可能在保持高畫質的前提下，採用更小型輕便的鏡組 — 也就是更小型的全幅 DC。

儘管這一切，包括更輕巧更高畫質的鏡頭聽起來都很美好，更是非常適合較為講求可攜性的無反相機產品。但鏡頭設計的改變基本也意味著 Alpha 接環很可能將會有極大的改變 — 也許可以沿用現有 FE-mount，但理論上對應曲面感光元件的鏡頭應該是完全無法在以往的 Alpha 無反上使用（搞不好平面感光元件的 APS-C 相機可以勉強沿用？）。

以往，普遍猜測曲面感光元件的出現應該是為了彌補 Sony 相對於 Nikon 與 Canon 等對手，在打造鏡頭方面的技術劣勢而來。然而 Sony 近年來 G Master 鏡頭的表現，算是讓人看到了源自於 Konica Minolta 的工藝技術其實也毫不遜色於其他系統。所以 Sony 到底是因為曲面感光元件的技術還未到位，還是只是準備要在更適當的時機出招，這都是未解之謎。

假若這次 Sony 真的啟動了曲面感光元件的進化，個人認為理由大致應該會是因為市場上對手都已經追上了全幅無反的規格，甚至還端出了完全利用超低法蘭距特性的更誇張光學表現的產品。為了要拉開與其他人的差距，一套從感光元件開始完全進化的相機系統，將會是另一次超越的開始。

簡而言之，當對手都不斷在小巧無反相機掛上砂鍋大超大顆鏡頭的時候，Sony G Master 如果能端出保持同樣的光學品質卻在重量與體積上都更小巧的鏡頭。那麼別的對手真的是只剩下傻眼的份了。就期待一下這次 Sony 會不會端出這麼前所未見，將高階全幅無反系統打掉重練的產品了。

Sony to announce a curved sensor Sony A1 with “crazy high ISO”?

]

UPDATE: With only a few hours to go until the Sony Alpha launch event, the speculation is mounting about the mysterious ‘Sony A1’. This rumored camera is said to include a curved sensor, which could result in smaller and faster lenses. However, some more potential specs have now been leaked.

Rumor website Sony Alpha Rumors has reported that one of its sources said, “I saw the unseen [camera] and trust me, you will never be blind in the dark again. CRAZY high ISO.” It also seems that this new potential camera will use the E-mount and will be the “most expensive E-mount camera yet”.

If these rumors turn out to be true, then Sony is certainly kicking off 2021 with a bang. However, we’ll have to wait for the event at 10AM EST/ 15:00 GMT to find out whether there’s any fire underneath all of this smoke.

ORIGINAL STORY: The previously announced Sony launch will kick off tomorrow at 10AM EST, but it now seems that there could be an additional exciting camera added to previously rumored line-up. Past leaks have indicated that we could be seeing the Sony A9 III and the Sony A7 IV appear on 26 January. However, a new rumor suggests that Sony will also be announcing a full frame camera with a curved sensor.

There’s not a lot of concrete information about this potential new camera, as it appears that Sony is keeping its cards clutched close to its chest. Sony Alpha Rumors reported that its source said that all he had was “unofficial chatter”, so it’s definitely not a certainty that we’ll be seeing this curved sensor camera.

So what would be the potential benefits of a camera with a curved sensor? Essentially, a curved image sensor mimics the design of the retina in the human eye, having a natural curve rather than the traditional flat design.

Sony first revealed this technology in 2014, stating that a curved sensor design results in a simpler lens system that’s 1.4x more sensitive at the center and 2x more sensitive at the edges.

According to a report by IEEE on that original presentation by Kazuichiro Itonaga, a device manager with Sony’s R&D Platform, Itonaga said, “A curved CMOS sensor has a few advantages over a planar sensor. Because of the geometry, it can be paired with a flatter lens and a larger aperture, which lets in more light.”

If a curved sensor can result in smaller, more compact lenses and wider apertures, then this technology could be a true game-changer for the camera industry. We’ll have to wait and see whether Sony has managed to finally bring a curved sensor camera to market – and such a vague rumor doesn’t exactly inspire oodles of confidence that it will turn out to be true. However, only time will tell…
