小弟想買個EF 1.4x II Extender以加強小小白IS的焦距，但除光圈要減級之外，PQ會吾會有好大影響呢？而家八腦會賣到$29XX, 值得投資嗎？有冇師兄用過可畀d意見小弟？

Why not sell your 70-200 F4 IS and buy a 2nd hand 100-400 at around $10,000? The cost is about the same, you should get about $7,500 for your SSW IS and instead of spending $2,900 on a 1.4x and worry about the picture quality, just get the big white (that's what I have just done!)

fish30d兄的提議都吾錯, 不過我覺得大白的機動性始終吾及小小白咁強, 太重, 暫時吾會考慮. 我參考左網上一d sample相, 都算可接受.
而且支小小白IS只係買左一個月, 吾想咁快賣.

EF 1.4 II Extender, 成像可以接受.廉價玩增距值得投資.
大白機動性差 ; (

大白 focusing speed too slow!

In terms of picture quality, 100-400 is definitely better than 70-200 f4L IS plus 1.4x.

In terms of focusing speed,
I think 大白 would not be slower than 70-200 f4L IS plus 1.4x

我二月個買時問過價, 當時行貨賣$2750, 而水貨賣$2050.

最後都係係"天長"買咗個水貨黎玩, 慳返個700蚊仲可以買個二手Extension Tube黎玩.

個Extender入面得幾塊鏡片, 又冇乜電子零件, 真係唔係好值比多幾百蚊黎買行貨.

我個Extender多數裝係支384上面用, 間唔中先裝係小小白IS到用, 對焦速度又唔覺真係慢咗好多. 我未用過大白, 所以比較唔到對焦速度. PQ係差咗d, 不過如果你唔"聞"相都唔係好大分別.

網上有人話副廠同原廠影出黎個質素冇乜分別, 不過價錢就差一半咁濟, 我自已就未試過用副廠, 不過如果你有原廠情意結就買啦. (我暫時全部鏡都係原廠)
