CANON從EOS650開始就領先Nikon了吧
這句絕對是不正確的,650/620時代,EOS(台灣那時叫"幼獅")在職業圈根本是個笑話,快門時滯165ms/影像消失時間235ms是要拍什麼
,超音波馬達也還沒出(看後來持續多年的EF1.4標頭就知其速度與"吵度")與Nikon F801隨同一整群AF鏡及功能完整的SB24閃燈上市的氣勢根本不能比,更別提隨後F4/F4S再給人"王者駕臨"的感覺,機身驅動AF馬達在那時完全不會落後於Canon訴求的"量身訂作鏡頭驅動力"的理念.Canon是到EOS1出來,挾[十字感應對焦]及幾支[USM鏡頭]的威力才壓下Nikon,開啟之後20年霸業.
但無論EOS1、1N都還是保用快門十萬張,機身也多塑料,直到1V才全面金屬化及快門強化,在各方面讓Nikon難以說話.
測光及閃燈TTL一直是Nikon的強項,即使1V有了更多的分割區域,人工智慧仍難超越,幾個典型critical的運算就是搞不及Nikon;至於A-TTL並不如其名比他廠"先進",甚至可說準度大有問題,當時C家職業工作者90%以上都用Auto模式(閃燈外部sensor),至1V改E-TTL(
),也因為區域分割方式尚在摸索並未取得優勢.1V是第一台內建測光輔助資料庫的Canon,而這個概念是Nikon在1984年FA上首次推出的,其後不斷應用改良,故一直保有一定優勢.

這邊在談EOS3和1V
CANON和NIKON的陳年舊帳就不扯了
EOS3是1998年出的
閃燈系統就是ETTL了
Canon Camera Museum EOS-3
A high-end SLR camera for professionals and advanced amateurs. This camera has many innovative features such as 45-point Area AF, high-speed and precision Eye Controlled Focus, and 7 fps high-speed predictive AF continuous shooting mode. The EOS3 is a camera which can fully respond to the photographer’s intention. It retains many of the features and operability of EOS-1N while also incorporating various recommendations and requests submitted by EOS-1N and EOS 5 users. It also reflects a variety of recent trends and developments in the SLR industry. This model has 45-point Area AF by Canon’s originally developed CMOS sensor and new focusing optical system. This AF system offers high subject-capturing and unrestricted framing capability. Eye Controlled Focus, refined to make it almost twice as fast and more precise than before together with 45-point Area AF system bring EOS3’s high-performance AF system another step closer to the human eye. The 21-zone evaluative metering linked to the focusing points, multi-spot metering with up to eight readings per exposure and eight metering system, including E-TTL autoflash with 550Ex are applied to this camera as well. The superb operability is achieved by dual electronic dials, 18 custom functions and firm grip holding, using the same material and design as EOS-1N. The same level of protection against moisture and dust as EOS-1N and silent film rewind are also provided. The high-performance 1/8000sec. shutter unit passed Canon’s standard endurance test of 100,000 times shutter cycle. System accessories launched at the same time as the camera include Power Drive Booster PB-E2, Ni-MH Pack NP-E2, Speedlite 550EX, Remote Switches with better clip-on operability and an anti-fog eyepiece. The nine Ec- series focusing screens for EOS-1N are compatible.
EOS1V是2000年出的,EOS3和EOS1V的對焦系統/測光系統和閃燈系統是一樣的
另外Canon TTL系統的發展史

至少我的2007年的580EXII用在1986年的T90上沒啥太大的問題

jenhoxen兄,
EOS650, 1987年3月發售.
EOS620, 1987年5月發售.
在這之前,Nikon只有一台F-501, 1986年4月發售.
在這之後,Nikon在1987年6月發售了F-401.
(以上資料來源,日本相機,相機年鑑)
Canon發表EOS系統的時候,就已經發表了USM,搭載的鏡頭是EF 300mm F2.8L,之後漸漸普及.
不管當時Canon EOS的表現如何,全電子化的接環已經領先群倫,先進的架構預告了未來的驅勢.
當年,AF SLR最強最完整的絕不是Nikon,是MINOLTA,親身經歷過的人是不會忘記的.

)後來有機會pk兩個系統的AF表現,用火車比喻大約就像柴油車頭和電力車廂(通勤列車)的差別吧.
