感覺比較像 3D 的等級. 但是沒有 Eye Controlled Focus. 雖然希望是真的, 不過我不太相信, 最少那個 1D level weather sealing 就與 Canon 一貫的產品線規劃相背. 反正是謠言嘛, 聊聊愉樂一下就好了, 別太當真
之前就有謠傳 Canon 要把 5D 這個線一分為二. 初階版為 7D, 12 mp FF 4-5 FPS single DIGIC III, 訂價在 usd$2500 左右, 而中高階會在性能上接近 1D, 為 1.3x 的' 1D 系列劃下句點.
這也接近我的猜測, 很白目地用畫素數來計算 throughput, 現在的 Dual DIGIC III 大概可以處理 100 mpx per second (1Ds III 21 mpx * 5fps, 1D III 10 mpx * 10 fps), 如果來個 16 mpx 的 sensor, 那每秒應該有 6fps 的 throughput. 如果這台新機像 D3 一樣支援裁切模式, 那就是一台同一塊 sensor, 但是面積大一號的新 1D. 然後可以用 10 fps 拍 APS-H, 說不定也可以用 12 fps 拍 APS-C
如果真的做到這樣, 就算價格是 usd$5000, 也很抵買.
