如果7D跟5D3價格差4萬,這樣賣點不是很明顯
小弟夢到內容......價差超過這個數字怎麼辦......
我還是回去多做夢好了......

Rumors 提到 Eye control autofocus(恕刪)
不太可能在5D等級給這樣的規格
看看之前出的1DX這種追求快速操作的機種都沒配置了
怎可能入門FF配這套系統?

Eye-controlled focusing
Through the tracking of eyeball movements, EOS cameras equipped with eye-controlled focusing (ECF) are able to choose the appropriate autofocus point based on where the user is looking in the viewfinder frame. ECF comes especially useful in sports photography where the subject may shift its position in the frame rapidly.
EOS cameras equipped with ECF are the EOS A2E (U.S. model names are shown; see the table below for equivalents in other countries), EOS Elan IIE, EOS IXe, EOS-3, EOS Elan 7E, and EOS Elan 7NE.
Canon has not continued its use of eye-controlled focusing with its digital SLRs, however. The EOS Elan 7NE is the last EOS camera to have this function.

我已經忘記以前使用過的眼控對焦底片機型號了,畢竟10年以上了
所以也是有可能如你所說沒用在1V
但是如果5DIII真的加入眼控,我覺得對於我來說會是超級大加分!
光不用手動選擇對焦點就真的方便很多
更何況以前底片機的眼控確實是可關閉的
不過我還是抱持比較懷疑的態度就是
因為先前有傳出Canon沒在後面的數位相機加入眼控是因為牽涉到軍事用途
真實情況如何也差不多就可以知道了
我只能說眼控真的是一張牌,因為真的不錯用!

訪談摘錄:
axi:
...下面談一下大家關注的眼控對焦功能(ECF)。EOS 1V沒有ECF,是對它的實用性有了新的認識嗎?還是出於為今後型號留下升級功能的餘地?
丸山太郎:
沒有留一手的考慮。EOS 1系列相機的設計都是從滿足專業性能、保證相機的高可靠度出發,而EOS 5、3這一檔的機型主要體現的是新技術與新功能的開發與應用,它們的設計理念有所不同。對於EOS 1V,我們的重點放在了提高取景器的影像質量、清晰度、放大率以及提供屈光度調節和100%的取景覆蓋率上,這些功能與眼控對焦相比,更能滿足專業攝影師的實際需求。另外從相機取景器的結構空間考慮,也不能同時裝入那樣多的功能。
axi:
也就是說在相機的性能、實際需求與製造工藝與能力方面存在著一定的衝突?
丸山太郎:
是的。由於空間有限,我們必須做出取捨。
axi:
對於這種取捨我能夠理解,不提供眼控對焦功能還有其它方面的原因嗎?
丸山太郎:
眼控對焦功能有相當好的實用性和相當高的準確率,但在使用中它還達不到100%的可信賴程度,這也是此項功能不被採用的另外一個原因。
