朋友廉讓了一部Canon30D給我，想買一支二手天涯鏡練習攝影，貪其方便，想請教師兄以下天涯鏡那支質素較好及對焦較快:
Canon 18-200 IS
Sigma 18-200 OS
Sigma 18-200 non OS
Tamron 18-200 non VC
Tamron 18-250 non VC
Tamron 18-270 VC

[TKWL]

唔通D師兄對天涯鏡真係不屑一顧

[yuigun]

Tamron 18-270 VC
or
Sigma 18-200 OS

Canon 18-200 IS 可以無視(紅圈價錢 kit 鏡質素)
Sigma 18-200 non OS 紅圈鏡(外型最強)

我都用緊 canon 18~200 is
都唔錯.........!!!

CANON 18-200 IS is NOT that bad as long as shoot RAW, because the most serious problem of this lens ---- chromatic aberration, can be corrected when shooting RAW

多謝師兄意見，但我都想知以下天涯鏡對焦速度那支最快及相差多少：
Canon 18-200 IS
Sigma 18-200 OS
Tamron 18-270 VC
