有朋友用過嗎？和canon kit lens相比如何？請給意見！

呢支鏡在光圈大是小心有黑角, 不過非常方便.
如果真的要配FILTER的話,SUGGEST 用SILM 的.

呢支鏡幾方便﹐使用上當然好過Canon支kit.

不過唔收光圈的話成像質素非常一般。

個range 就好過

[hkres]

咁既價錢呢講係超值。

個 range 真係好方正。

我覺得最靚係 f8，但 f3.5 都可接受，但眩光問題比較嚴重，要避角度。

F8 is very good!
you may find it can produce very high contrast and sharpness in F8! Amazing!

If f/8 is still unacceptable, I will throw it........

如果只用最大光圈時比較成象質數呢？
和kit lens比

大光圈又要sharp 只有 sigma 18-50 f/2.8 同 17-40 f/4L

oh... sorry. I am using D70. I think Canon will produce more soft image. It depends on your needs and requirement.
For me, I agree that using Nikon DSLR you can buy some cheap lens but with sharp image. Inversely, Canon should use better lens (L) for producing better image. Just my experience.

(P.S. I used 300D, 10D before, I can say, I utilize these two camera, and I love them very much even up to now. Only disappoint me is focusing problem and sharpness)

"大光圈又要sharp 只有 sigma 18-50 f/2.8 同 17-40 f/4L "

這個當然，我只是想問Sigma 18-125mm和canon kit lens在最大光圈時的比較。

[rickwok]

剛剛在網上research，發現sigma的18-200mm竟然比18-125mm成象還要好一點，真的嗎？有朋友比較過嗎？

另外，sigma 18-50 f/2.8值得買嗎？雖然對我來說是貴了一點>_<

"Sigma 18-125mm和canon kit lens在最大光圈時的比較。 "

五十步笑百步

"另外，sigma 18-50 f/2.8值得買嗎？雖然對我來說是貴了一點>_< "

18-200, 18-125 只是range 大了，來得實用，在光學質素方面，同kit lens相比所差無幾，就好似上面位人兄話 "f/8 is very good" ，要收兩級光圈以上先叫"very good"，這樣既情況都在kit lens 出現。 再講18-200個range禁大，唔會好得去邊。 至於18-50 f/2.8，確係好sharp，就算最大光圈都好sharp，不過CA同黑角問題比較嚴重，值唔值得就見人見智。
