小妹最近想買一個天涯鏡來配我的500D。
我是新手，EF-S18-200mm f/3.5-5.6 IS 或者 Tamron AF18-270mm F/3.5-6.3 Di II VC 比較適合我呢？
請給我意見。價錢不是問題。

Tamron gives longer tele.
Canon gives you faster (just a little bit) focusing.

Tamron has (reportedly) better image stabilization (VC for Vibration Compensation)
Canon lens on Canon DSLR could have black corners (vignetting) corrected.

I have been using Canon 18-200 for 2 years.
