我用緊400D Kit set, 依家想選購新鏡作旅遊之用.
因我係個新手, 煩請各c兄比d意見. ^^

揀 Sigma 18-50 原因係有f2.8 恆定光圈同marco, 但個range多番少少比較好(因旅遊) (價: 31xx)

揀 Sigma 17-70 原因係個range好dd同marco, 但係唔知這鏡相質會否比sigma 18-50差點. (價: 28xx)

揀 Canon 18-85 原因係有 is同個range, 見過網友的相真的比較清和銳. 但是聽說暗角同變形比較嚴重 (價: around 4000)

希望各位可以給小弟一點意見. 謝謝.

小弟唔係師兄
不過都有少少意見

其實以上三支鏡小弟都未用過
不過見好多師兄都話canon 17-85mm 影出黎ge 質素麻麻

而死馬個兩支
17-70mm f/2.8 - 4.5 好多師兄都話光圈跌得太快
淨係17-21mm 左右先有
不過另外個支 17-50mm 雖然係恒定2.8
但係相ge 質素冇上面個支咁好

個人認為canon 個支唔使諗
因為質素麻麻之餘最細光圈得3.5
而死馬兩支
我覺得睇樓主需唔需要恒定光圈
要ge話就入支恒光
唔要就入另外個支
因為我覺得兩支個焦段都ok
去旅行想影wide d 多過 tele

更正
canon 個支最細光圈得f/4

去旅行用的話其實你有冇諗住帶埋支夠穏固可以支撐400D既腳架呢?如果有的話你可以忘記Canon支is鏡.
次次講親揀鏡頭大部份人都一定淨係考慮光學質素.在我來講影唔影到絶對比這個更重要.
假設你唔帶腳架,唔通淨係日光日白先影相?室內夜晚全部唔影?還是你打算開盡光圈,用超高iso?我可以肯定話,就算唔計高iso的noise,同一場景當f2.8影到唔手震,咁用f8加防震都一定影得比較好.仲有雖然老套,旅行點都要影下D人加景到此一遊照.下下大光圈淺景深我諗唔係咁合一般人口味.有D人仲話帶支50mm f1.8去應付低光,咁真係要問一下你係因為手震要用f1.8定係其他原因呢?光線夠你會唔會唔理副作用而用咁極端光圈呢?

I have also considered between Sigma 17-70 and Canon 18-85 but have decided on the Sigma 17-70 after reading very good reviews on it. One review said that it is better than the Canon 18-85. Also Sigma 17-70 has won the best zoom lens in its category in a vote held by Di-Gi magazine.

I have bought this lens and am very happy with it. It is very sharp and the range is very good. With this zoom range, "is" is not so important for me.

謝謝兩位的意見.

Canon 18-85 IS 依家邊度有得買呢? 是否仍要$4000?

真係想影好相既就唔好理禁多IS果D野，拍手震就用腳架，光學質素差就冇辦法補救...

次次一講親IS就實有人教人唔好學懷手勢要用腳架,實情就係講果個人都轉頭就走去唔用is夾硬開大光圈,高iso去手持影低光.講到光學質素咁重要但係又可以咁求其?
我都識得唔小人初初就一鼓熱誠下下出腳架,影得三兩次支腳架就會雪藏.再懶D既就閃光燈都雪埋.
老實講腳架又係好麻煩既,尤其去旅行,又開又關真係想死.直情會俾同行既人埋怨阻住晒D時間.你要確定自己唔係得把口既先好咁做.
同埋實會有人睇完話低光要用is都會表示短焦距唔駛用is,除左覺得莫明其妙外我都建議佢地試下用is.
