Hi everyone,

I am a freshman in using my first D-SLR of Canon EOS 350D.

As I want to buy an one-take len for any environment to avoid frequently changing lens, may I be kindly informed by you which one-take len is the best in photo quality (for the range of 18-200mm) ? How about Sigma 18-200mm F3.5-6.3 DC or Tamron AF18-200mm F3.5-6.3 XR Dill which is the best, or other is better than Sigma and Tamron ? Also, what is the price of the said Sigma and Tamron respectively ?

Looking forward to your early and kindly reply, please !

我都是350d的用家
前兩天在dcfever買了18-200mm sigma
經過測試後，認為支鏡的水準比kit鏡好，在18-55mm的範圍內比kit lens 成像細緻，對焦亦好準，置於黑角的問題。兩支鏡都有，但不太明顯。
不過，sigma 支18-200mm 在拍攝時，最好收收光圈，如果用全開光f3.5的話，影像較散，建議調至f5.6-8，而我在用f8時是最好的。
雖然，我未用過Tamron 18-200mm，但我有支d2.8 28-75 di ll的鏡，相比之下，Tamron 28-75是好過18-200sigma，但其實兩支鏡都不同價錢，而且zoom程不一，只能大約知道Tamron的18-200會好少少。
