[疑難] 增距鏡

增距鏡

本人用400D及kitlens efs17-85mm 想拍超距物如鳥  本想買此欄師介紹之cannon ef-s55-350mm f/4-5.6 or tamromn af70-300mm f/4-5.6 macro1:2 ,但AFTER SEE MAGAZINE,發覺可用增距鏡達到效果,WANNA SEEK ADVICE!

增距鏡 = Teleconverter ? If you wanna use the teleconverter for your kts lens 17-85mm f3.5-5.6, I think you would not get what you want !

2x teleconverter will double up your lens focal ( 2x 85 = 170 then multiply with crop sensor 1.6x = 272mm ) this look good for you, you will get 272mm but this 2x teleconverter also will double up your aperture ( 2x 5.6 = 11.2 ), the problem come now, your 400D body AF ( auto focus ) will not work !!! ( for Canon enry level DSLR only support up f/8 only ).

It not not a proper way to buy a teleconverter for short range lens.

please visit to http://www.photomalaysia.com - insides this forum got a canon user sub forum

What is your budget?
55-250
70-300
are both good.  Also you may want to consider IS unless you plan on taking the tripod with you all the time.
唔好話離開髐G十年, 即使到死o個日我都會係香港人!!!

after searching info, final decide sEF 70-200mm f/2.8L IS USm + Canon Extender EF 2X II   is it good choice?

EF-S lens 好似唔用得 tele-extender 架喎... 會頂住

同埋用鬆鏡都係唔好增距喇, 定焦就另計
