오막포 영상촬영시 초점 잡음 질문입니다

답변 감사합니다ㅎ
영혹시 상촬영용 렌즈 추천좀 부탁드려도 될까요?

단렌즈로 무소음을 원한다면 MF로 촬영하면 됩니다.
DSLR을 이용 영상을 "AF로" 촬영한다는거, 생각보다 오래되지 않은 방식입니다. EF 렌즈 중에는 권할만한 렌즈가
EF 24-105 f/3.5-5.6 IS STM has internal focusing and is the quiet/silent EF lens for AF in video - http://www.the-digital-picture.com/Reviews/Canon-EF-24-105mm-f-3.5-... : "... The smooth focusing makes focus distance transitions easy on the viewer's eyes and the sound of the lens focusing is not picked up by the camera's mic. Even the STM lens' aperture changes are quiet and smooth."
EF 70-300 II 'nano USM' 정도
http://www.the-digital-picture.com/Reviews/Canon-EF-70-300mm-f-4-5.... :
"Like STM AF systems, Nano USM focuses almost silently, with only faint sounds heard with one's ear next to the lens. And, Nano USM focuses very smoothly."
