價錢唔係好貴(比原廠)
小弟用開canon發覺支lens既HSM唔係比USM慢好多
我覺得都唔錯~都好快
重又唔算太重
出黎個成像真係唔錯

同之前既師兄一樣
差防震啦
同埋個MARCO唔係1:1
重有D皮好易甩

本身想買小小白IS但係+左價所以就轉揀左呢支
估唔到呢支LENS幾好~對蕉快
靜比得上usm~當然原廠好d
差在冇防震...不過有既話呢支lens又變5位數字

價錢合理.
外型真係唔錯,短過小黑,小白.
影出來的成像ok o架.
對焦幾快,幾準.

冇防震. ( 有就唔係這價了 )
MACRO 唔係1:1 (不過小黑,小白是沒有MACRO的)

其實支鏡是問朋友借來玩,本人是用開小黑五的,用過之後感覺幾好,$6000比小黑便宜了成倍,
有師兄話它走焦,難對焦,但我又不覺很嚴重,就算小黑五也不是次次對得到,本人是用D700的,
裝上這支鏡後,真是沒什大問題,反之仲幾好用.

Decent image quality
Low vignetting even on full frame
Fast and positive autofocus
Very good build quality, excellent tripod collar design
Low price

Relatively weak at 200mm (softness, chromatic aberration, pincushion distortion on full frame)
Unconvincing 'macro' performance; soft at wider apertures, significant focus shift on stopping down
Red/cyan bokeh chromatic aberration

I am thinking of buying this one as this is cheaper then the Canon one (Sigma - around $6000 and around $9000 for Canon)

1. 對焦快、靜
2. 成像質素 正!!
3.有Macro

沒有防震

未試過走焦, 很滿意，雖沒VR,但他價錢的確比原廠的便宜,有了他已很滿足.
扣快門第一個感覺,快, 效果, 正!!

價錢平、對焦快、靜 f2.8 室內手持影都ok

重、

未試過走焦、只有難對焦

換了新都走焦？是否body的問題？

.............

.............

平

走焦

請問canon 版的 ching
你們的鏡有走焦嗎?
我買第一枝 70mm時最近對焦點時焦點前移2cm
f/2.8-4時剛好在景深範圍外...呆
拿去換支新
再走多1cm...仲呆

1. 以 $59xx 嘅price. 定價合理
2. 以咁嘅焦距, 輕
3. 成像質素ok

no VR (不過有就唔是咁嘅價位)

剛剛告別了支lens, 讓了給一位ching. 有點唔捨得. 因為好好用, keep得好新, 又有保養. 不過蓞嘅唔去, 新嘅點來

支lens 外型Pro. 手控易並且輕, 故此我多數旅行用或影D半運動照, 例如唔是太近距離的運動相, 打雀都ok. 雖然無VR, 但Sigma的OS (i.e. VR) 並不太出色, 又食电. 故此想吓個价, 都算ok. 並且影室外或用閃燈多的話, VR就唔是咁重要(此乃小弟愚見, 多多包函)

講到PQ及色水, 算good la, 但一比上Nikon LB3 就差了D, 我試過比拼兩支lens, LB3的contrast 和 清晣度好D (不過是放到原稿大的相來比較), 如果是普通4R size, 只是覺此lens影出來D相少少偏黄和鬆少少

總括而言, 咁嘅price. DG, HSM, Macro, f2.8 都有, 故此 值得擁有. 最多好似我咁, 毒癮起, 上LB5, 就打個拆, 讓比ching用la.

1. Good hand feel.
2. Easy to use.
3. Fast and quiet with HSM, then D40x can use.
4. Reasonable price.

This price, then not much bad point.

I had LB3 and do not want to pay too much to upgrade LB5 but have a D40x for travel use. After bought and go for trip, then it is a very good lens for trip compare to Nikon same size lens. However, photo quality - contrast and shapeness NOT good as LB3. Therefore if take quality photo, I will choose my LB3. If take photo for easy handling and trip, I will use this. Overall is good when considering the price.

1. 非常便宜
2. 有Macro
3. 鏡身較短
4. 比同級的小黑五/小白IS/小白輕

1. 對焦極慢, 我不知道其他朋友用甚麼機, 但這枝S 70-200在nikon D40x上使用, 對焦要一秒半
2. 經常對錯焦, 對毛巾/太細小的格仔/石屎地/木紋反應其慢, 甚至無法對焦
3. 沒有防震
4. 鏡身沒有button set為手動對焦
5. QC差, 我到八間不同店, 每間check了三四枝, 到最後一間才買...

因為沒有太多資金, 加上不是做job, 所以決定省八千元買下這枝Sigma 70-200 Macro
如果有錢的nikon朋友, 建議用小黑五
canon的朋友, 即使用小白 non IS也比它對焦快
