想請問：以上增距鏡是否可用在canon任何鏡頭上呢？副廠鏡又可以馬？

[marketmarket]

並不是任何鏡都可以用增距鏡，白身鏡就多數都得

[look_yau]

from my experience, Kenko one is better

kenko 兼容度比canon 原廠大... 防塵防水滴就原廠較佳...
kenko 同canon 都用過... 1.4x dgx vs ii... 感覺上差唔多... 原廠好少少... 2x iii 原廠就好過kenko 好多好多... 由其是邊位角位...
基本上canon 原廠extender 只支援101mm以上定焦鏡+70-200白鏡+100-400
70-300 冇寫話得而且未試過...
可以去睇返canon 官網... http://www.canon.com.hk/tc/product/catalog/productitem.do?categoryID=25&seriesID=10034
再去睇支鏡o既"技術規格"... 就會知道對唔對應同對應d 乜....

I have Sigma, Kenko DGX & Canon Extenders version 1, used with the following lenses, SSW, SW, SWIS, 384, 584
quality overall are similar with the CANON a little bit better (I don't haver version 3 extender)

Major advantages of using Sigma & Kenko
(1) one important thing is that using Sigma & Kenko, u may get AF even if f8, e.g. my version kenko dgx 2x can use AF with 7D+384 @f8
(2) your can stack 2 converters (only Extender III can stack), e.g. 584+two 2X can give u optically similar to a 2000mm lens

Major disadvantages, u must try before use with a specific combination of lens & converter, e.g. I can get AF with Sigma 150/2.8 macro with Sigma & Canon 2X, BUT cannot with Kenko DGX 2X (quite strange?!).

Thank to All

70-300 係不能兼容,因後鏡組太突出

[manson535]

70-300 Kenko 1.4x 可以兼容,我用緊.

[karithkung]

因為個Kenko 1.4x extender 設計不同,可能兼容所有canon鏡頭
