好少用長鏡，慳位慳錢計，想買雜廠2X代替，加在EF100/F2.0上。

質數要求吾高，只要求正常Auto運作，最緊要平！

請各位介紹！

老實講句, 增倍真係忌貪心. 1.4倍通常都OK. 上到1.7同2倍, 銳利度大幅下降不在話下, 再加埋D高光位勁出紫邊之類... 咁嘅表現都可以接受, 買支副廠70-300mm好過啦.

副廠70-300mm太大支，我買過，因為少用所以賣左。

請推介最平的副廠2X, thanks!

如果要平... 又有AF, 我諗kenko 2x 就差唔多最平(mc4, mc7, pro 300....) , 二手mc4 $3xx 夠曬平.... 不過質素都冇咁好

Hi,

I wish to know that if using 1.4X mount to 70-300mm/4-5.6 Tamron lens
Is it work ok while the len set to f300mm/F5.6 ? How about the image quality?

And how about the price of 1.4X in second hand ?

Thanks

hi seesee,

I try kenko 1.4x before with Nikon 70-300G F4-5.6 in many years before, AF and metering also is work. However, AF function need a few seconds to fcousing.... and the quality is poor.... the aperture at 300mm max is F7.8, is very slow><

Thank you very much cola cola man

~.~ It seems I may change my idea to second hand 400mm reflective lens or equivalent now.

Thanks again and have a nice shoot.

rickwok,

Brother, you better check. I don't think Canon 2X can fit with EF100 f2.0. Other brands of extender may, but before you buy anything you should check this out.
