本人是新手一名，想買支18-200mm天涯鏡， Nikon 原廠同 Sigma 都有呢支鏡頭，Sigma只係冇VR，但價錢差好遠！ 請問兩支鏡頭的質素係咪爭好遠？ 值唔值得比多幾仟蚊買原廠？請各高手指點，thanks！

用得天涯鏡照片質素吾會好高，Nikon 果支我有用過，真係唔值呢個價，Sigma果支睇過D 網支post 相質素OK 唔差!

>>Sigma只係冇VR
Wrong!

Sigma 都有支18-200 mm, F/3.5-6.3 OS (72mm ID, wt = 650g plus)
(OS stands for Oscillation Stabilizer = 震動穩定 = 防震)

Sigma has an earlier version w/o OS. It is smaller and lighter. Later, they launched a OS version, which is bigger and heavier.

nikon 既 tele光圈比較大小小，F5.6

近排見到某間相機店做緊 promo
Tamron 18-200 $12xx
可考慮下

OS / non OS 兩支成象差天共地

永恆的光輝??

但好似要連埋Nikon D80一齊買，同埋Tamron呢支冇防震o架，所以做到咁平去清貨o羅。

多謝咁多位賜教，等我知多D先去問價。 昨晚便去左舖頭問價，原來支原廠Nikon同Sigma OS 18-200mm 都係相差大約二仟元唔夠，當然Sigma個價比較合理D，而家心大心細。

無VR or IS 200mm一定要落腳 有都要夠光猛 唔係碌鏡再利都係得啖笑
個人一問:點解要天涯鏡?nikon甘多新舊好鏡唔用反而買又貴又唔靚既~

家下廿四-七十確令我心動隨左價錢(未買果隻) 380mm既最短距離 其如我得碌 17-35再黎都係定蕉 無咩唔方便諗下50 f1.8 平靚正 有小遍紫藍(又如何我唔晒搞色準搵食出廣告) 但成像sharp平 不防買黎玩下先 之後就會發覺天涯鏡小喇叭

先唔講外殼講造工, 如果在戶外夠光環境下, Nikon 18-200 VR 同 Sigma 18-200 OS 真係差唔多.

但係如果在光線略陰或室內, Sigma 18-200 OS 在 200mm 段 光圈只得 6.3, 而 nikon 個支有5.6. Sigma 18-200 OS 相對就更要推高ISO去遷就. 此時自然就見到值唔值得比多千零蚊買 18-200VR 了.

半級光圈2千元..1級ISO唔洗錢..各自各精彩啦....
