Sigma 17-70mm f/2.8-4.5 DC Macro (已停產)

評測報告

Very sharp image(nearly comparable with my 50mm f/1.4)
Good contrast and saturation
Also have MACRO
relatively larger aperture
Good built
Very good price (good 2nd hand goods now around $1800-2000)

MACRO magnification is less then desired( its not a real dedicated macro lens anyways)
Lens tube will slip backward if the lens is facing up
rapid fall in max aperture from 2.8-3.5

Its AMAZING with its price
Really cannot ask for more

FAll in love with it instantly!

--相當銳利,整體不俗
--焦距實用
--Macro
--影像富層次感慢

--對焦噪音頗大,似電鑽...
--而且慢...
--F/2.8只出現於17mm...
--無防手震...

當初因為相機佬朋友熱烈推介下無要支kit lens,要左呢支...
亦因為佢而踏上左攝影不歸路...

17mm影風景一流,一機一鏡無問題~~~

其實對焦方面嘅問題向HSM版應該OK(無證實,唔好插...XDD)

Range: about 70% of my photo will use this range;
Marco: it leads me to another world - marco shooting;
Price: acceptable.

HSM: missing for Canon mount;
Image: not full range for F2.8;

Tamron A16 or Sigma 17-70?
It is hard to choose.
I asked myself.
Are you need a Marco function? YES.
How many photo you need the range 50-70mm? about 30%
OK, go ahead to Sigma!

光圈比kit鏡大一級
range 方便
質素好過kit
72mm口徑超有型

冇咩....
呢支同18-50 f2.8
我會揀 18-50多d
因為恆定確係幾好

冇後悔買呢支
用黎長用幾好....
72mm 放係部機度
真係幾靚
咁既價 又係唔可以要求太多
質素過得去....
但係a16 應該sharp過佢
好過canon 支17-85 kit lens

價錢唔貴
色水好~輕有marco
雖然17-2x mm先有f2.8但係都ok夠
唔重

sigma的鏡身物料一般

物有所值

Range 十分理想，
2.8光圈在室內很有用，
又有微距，扺玩，
有點重量，令手感不俗(個人認為)
價錢平 ，
成像算不錯 (當然唔可以同L鏡比)。

2.8光圈極短，扭多少少就要變細。

以這樣的價錢來說，相當不俗，尤其個range + 大光圈，真係相當好用。replace 支kit仔一定令你滿意。
