有防震
18mm -200mm方便
金屬接環

光圈不夠大
重一點

手感唔錯,交足功課

一鏡走天涯，有防震，有質感，對焦速度都幾快 (比較Tamron而言)，最重要價錢合理 $3,500左右，重係行貨。日太製造。

光圈不夠大，只有 f/6.3。色澤有少許偏黃，

整體滿意，外遊、記招首選！！

range十分方便...
os係標準距離都仲有d用...
手感唔差...

200mm f/6.3 太細...
os得兩級
色澤偏黃....(都頗嚴重.....)
膠身
對焦有d慢...
連hood

一定要預佢d色出黎係黃d架啦...
較wb就燈塔想較藍d都無乜用...
同埋os真係5夠....不過如果當練技術都無咁灰...
整體唔錯...

平，成象唔差得過nikon 18-200vr

18mm 有黑角

手感唔錯，價錢平，日本造，一鏡走天涯很方便。

天涯鏡18-200mm
防震
價錢合理(行貨3980)
canon原廠無出
手感不俗
成像不俗
對焦速度可以接受
配件齊全

重 (用於400d上有前後不平衡)
大(鏡頭口徑幾大)
防震不明顯

如果想一支過，唔多想換鏡，是canon用家值得使用之選。但比想像中重一點。

水、行都係日本做，有質素保證。
最平見街3150，真係超抵玩。
18-200mm真係好夠用，仲有os。

頗重。
個OS無想像中咁勁，如果暗都要上高個ISO，唔係實震。
光卷太細，6.3，好難做到淺景深，相片算清晰但平淡。

因為canon無出呢個焦段，sigma呢支OS應該係首選。

旅行用都算OK，因為你唔會有時間掛住換境，而忘記自己主要目的係：睇風景、旅行、玩。

如果帶多支輕身嘅定焦大光圈，其實已經應付到極多場合。

Good range of focal length for traveling; with Optical Stabilizer function; Come with the hood.

Do not expect high quality photos. The photos from this lense are not that sharp, colors doesn't come out good (tends to have yellowish color), and cannot produce a good depth of field effect. Almost all photos need to be edited in Photoshop. This lense is also a bit heavy. Consequently, you can get tired easily if you are used to carry the camera around your neck with the lense attached. A major disadvantage is that there is a very annoying chattering sound when the Optical Stabilizer is turned on. At first I thought it was just something wrong with my lense, but later the staff in Sigma Office told me that is how it suppose to sound. The staff showed me another new lense with the same model and the chattering sound was still there.

The price is reasonable, but the disadvantages mentioned above may have outweighed its usefulness.

三千九..算抵玩一款, 一鏡走天捱,確實方便很多, 有防震

很難玩淺景深, 光圈太細F6.3, 但拍廣角景,收細光圈F8,就細緻清晰, 色澤有少少偏黃....,要用PHOTOSHOP執...

三千九, 倍數高,有防震...算係咁既質量,一分錢一分放....但求方便...

One lens 18mm~200mm great for travel, not too heavy, good price $4200, came with hood. Seems a very good choice besides original canon lens.

indoors better use iso 400, 200mm F6.3, focus motor a bit slow, motor sound a bit loud, after all considering the price, it is good value.

Very convenient, surprising sharp at 200mm, OS is very good for beginners like me. I've use Canon L 2.8 lenses, 16mm~35mm, 24mm~70mm, 70mm~200mm, full set very very heavy! now one lens can make reasonably good photos, of course, f2.8 is much easier to control aperture and and shutter speed for indoors. Sigma 18mm~200mm seems to be the best all round lens for my beginner photos. I took around 3000 photos for portrait, landscapes, indoors, outdoors, food, flowers... very satisfy with my investment.

以為 18-200 的 lens 好差 , sigma 今次完全推返
sharp , 出到色 , 對焦幾快和準

表皮物料一般

一支鏡 , 去旅得 , 非常方便 . 正正正
