支鏡由 50mm 打後開始唔掂，光圈最佳位罝在5.6-8之間。

灣仔 CAM2 水貨賣緊 $1990，行貨城城賣緊 $2550 (?)。

我都買左，當佢係 18-50mm 黎用，50-200mm 就當係 bonus，好過冇。

Canon 18-200 is much better than sigam, picture looks sharp. even over 150mm in day time. May be can think about second hand. good luck

多謝pongyee寶貴意見
18-200
50mm 打後開始唔掂,等大家知道果d kit/天涯水平

如果有明白多些physics的朋友,會同意.
定焦係王,變焦唔可以多三倍.
變太多,再修正光學,好因難.
CANON定焦lens好多,幾好

我就覺得焦距太寬既鏡, 質數一向都嘛嘛地~

尤其係 canon 枝 18-200, 質數同價錢實在唔係太合理, 如果要我買呢枝, 就不如買 24-105 or 17-40 好過~

I use my 18-200IS with 50D, the quality is far better than I expected, give very good & sharp photos @f5.6 to 8.

I also have the 18-200 sigma non OS, the quality is well below the Canon one, I don't have the 18-200 sigma IS version, cannot comment

Thomas1, yoshiki321 (agree with u that ultra zoom quality is not that good), but u 2 better try the 18-200IS of CANON before making conclusion.

The only problem 18-200IS is the CA problem @below 2x mm, but after shooting RAW & fixed with software, the quality is far better than I expected.

Highly recommended if u can shoot RAW for the wide angle below 2x mm

Obi-Wan師兄 你用原廠18-200係較sigma 18-200好.
當然價錢原廠貴些.
canon 18-200在canon show room 玩左.當時覺得可以,但show room
燈光set 得好.最終冇信心買.
多謝你好detail回覆.

灣仔 CAM2 水貨賣緊 $1990，行貨城城賣緊 $2550 (?)。

咁平? 係咪 non OS 版本咋?

我買果支有 OS 水貨都要 $2880, 咁我咪買貴咗好多???

[Thomas1]

買左開心去影,下回買睇定d.

[Obi-Wan]

non OS version of sigma, 2nd hand around $1400

[ltyjackie]

唔該晒各位師兄意見

[ksnsk]

我買左騰龍支18-270
四千蚊唔算好底玩但係就一支搞掂晒！
f/3.5-6.3 雖然唔係大光圈但係都可以玩到淺景深好好用！
人地話對焦慢，我覺得可以。
防手震真係好強！
可以諗下！

鎖你。不是 OS 版。

定焦成像最靚無可置疑，但求方便一鏡走天涯必須作出犧牲，相片質素能否接受因人而異。也與拍攝目的有關。
農曆新年期間曾往北海道旅行，相片大多用canon 18-200拍攝，鏡頭質素如何，各位師兄可自行判定。
