1x 1.4x 2x 2.8x 點解
真係一分錢一分貨

1x 原裝, 400mmf2.8
1.4X 加咗 1.4X增距鏡, 560mmf4.0
2X 加咗 2.0X增距鏡, 800mmf5.6
2.8X 加咗 1.4X增距鏡再加2.0X增距鏡, 1120mmf5.6[光學實際f8.0]

睇黎我要對增距鏡改觀, 竟然重可以咁sharp
對焦有冇慢到?

一般鏡加1.4x ok既, 用到 2.0x 就好散[我支300mmf2.8 都唔掂,散哂], 2.8x 重散.

但估唔到支400f2.8 用2.0x 都冇問題, 收多1級光圈 (5.6), 都ok  2.8X 仍可接受.

不愧為canon最高成像鏡頭

對焦 未試到, 一般用1.4x 都ok, 2.0x就明顯慢同難追焦, 2.8X就未必對到添

其實dd兄你都好勁，我亦好羨慕你，其...

長期客仔

要100%清 雖要 全片幅機 + 高成像鏡頭

全片幅機= 1Ds / 1Ds MK2 / 5D
高成像鏡(我估計的排行)= EF400f2.8 -> EF300F2.8 -> EF500F4.0 -> EF600F4.0 -> EF85f1.2 -> EF200f2.0 ->EF135f2.0 ->EF35f1.4 等

而非全片幅機 1DMK2N 成像最好
最高成像变焦鏡係 EF70-200f2.8, 但想 100% 清, 要有好高條件(技術+環境)先有可能.

可以參考吓: http://www.26fun.com/bbs/viewthread.php?tid=117044&fpage=3
#1 但當時只用 jpg 冇用raw, detail 度略低. 希望幫到你.
