As shown in the sunject.

And which one is better??

[ks chung]

if buy, buy 1.4 instead of 2X.

Kenko teleplus pro300 2x 的, $950

我當時都煩究竟買 1,4x 定 2x ， 後來有有了結論

- 2x 一定差過 1.4x ， 而原廠又好過 Kenko
- 2x 同 1.4x 差唔多價，原廠就貴一陪有多
- 要keep住靚盡質，就1.4x 原廠
- 要純粹玩下，過下長焦引，就 Kendo 2X 平平地玩過算了，反正 Canon 2X d人都話係餐d

Kenko 1.4X can be used on all lens. But, canon 1.4X can be used for tele-white lens only.

[viovanda]

depends on ur lens ,if your lens is F2.8,it is ok for using 2X ,if not ,1.4X

[h0001244]

係呀，Canon 1.4x or 2x 只能用响白鏡或135m F2 度，因為entender 佢凸左塊鏡片入支原鏡度的，所以，副廠鏡未必用到

kenko個支就連魚仔 tokina 10-17 都用到， 不過用了就 = 無買過魚仔

仲有試過 kenko 2x 配 tamron 18-200，即使日光日白，都AF唔到，因為 5.6 + 2X 後 係F11，光都對唔掂，死火！

F2.8 長鏡就好岩洗
