(1) range is very useful
(2) IS is very useful, and really workable.
(3) The price is acceptable, cheaper than 24-70mm which did not have IS.
(4) The size and weight is okay.
(5) provide善意的味精.

I personally cannot find any.

我主要用此鏡影人，我發覺此鏡能將人的面影得〝白裡透紅〞，極靚的效果，你根本無需叫model化裝，在outdoor，效果更顯著。我用non L Canon Lens影人，絕無此效果。

1. 對焦準
2. 對焦快
3. 顏色豐富好多

1. 光圈得 4.0, 有 2.8 就好\'
2. 貴
3. 最小焦距得 24mm, 乘埋 1.6 影風景絕對唔夠用

除左價錢貴小小同光圈細左小小, 總括來講, 呢支鏡真係正!

- 成像和色水很好
- 鏡身紮實
- 有IS
- 對焦蠻快

- 暗位有時對焦有點困難
- F4 光圈，有時未必夠用
- IS 開啓時頗食電

此鏡質素絕對OK，
如果用在1.6x crop 機時，
24mm 未必夠wide，(38.4mm)
但Tele 位有105mm, 相當於168mm,
絕對夠平常用，
如要買此鏡時應考慮是否能接受此廣角程度，
否則的話應考充慮crop 機用的鏡頭。

買入此鏡的決定是因本身已買入10-22mm，
再配合此鏡就有一段很好的焦段，
(相當於 16- 168mm)
及有更佳的影像質素

去旅行帶此鏡頭，已經可以一鏡走天涯。

如果是2.8光圈就無敵！

用了一年多，覺得沒有買錯。

Sharp. Fast. Colour is cool. Outlook is mint.

This is my third copy of 24-105mm lens. The first copy I bought in Broadway which the image was soft and had a little bit out focus. So I returened to it and they welcomed me to have a second copy. The seond copy was sharp but the i.s. was a little bit slower than the first copy. Finally I changed to the third copy and this time everything is alright. So anyone who going to buy this lens should not accept any acceptable "sharpness" quality of this lens. The lens can reproduce a sharp image in condition that it's not a bad copy. Don't give up.
After using it, you will love the zoom range, colour and outlook of it. Anyway, lens is still a tool only. You have a cool image or not is still depend on how you use the lens and processing the raw.

外型勁討好~成像非常銳利~色水靚，冇得挑剔，L鏡係唔到d~!!
黃金焦段!!!實用性高，係一支必需的標準鏡首選!!~

暫時唔覺有~有都係---『貴』啦

本來用緊支EF-S 17-55mm F2.8 IS USM，後來放了買了這支~
感覺比17-55銳利得多，除了光圈較細外，但我最主要睇成像是否銳利~
這支絕對稱職，感覺沒有放錯17-55來換這支!!

成色成像無與倫比
有IS 同USM 令拍攝得心應手
77mm 外型殺食
價錢合理

都係個句:

光圈唔夠大

伸縮鏡藏塵易

焦段適中
成色成像無與倫比
與17-40L 比較經取捨後還是選擇有IS.
有IS 同USM 令拍攝得心應手
77mm 外型殺食
以HK$8xxx 既價錢...真係無得\"頂\"
何況本人以7千頭入手..!
但光圈再大少少更perfect~!
overall 此鏡唔推都大把人買....

手感好
一般用好夠

唔夠wide, 去旅行時差小小

無黑角問題
可能用2舊, 唔覺食電
如果出18-200mm 或以上L鏡就perfect

對焦快, 色正, 有IS 24-105焦段實用

貴 & 食電

用400D ,24-105mm x1.6 = 38.4-168mm very good ! 人景都ok !
之前用副廠Len Tamron 28-75 F2.8 ,,比較之下 ............當然24-105 Sure win !!!!
各方面都優勝,尤其是清晰度,真係無得彈性

外型勁殺食 , 好好揸手
usm , is 好正 , range 最常用
相好sharp , 好細膩 ~

外變焦.....伸出伸入, 同埋個變焦環比較貼機身<----唯一唔好的地方
冇其他唔好

買果時覺得好貴, 買左之後覺得好..........買左你咪知囉, 日日都要飲美沙同 !!
家下7千幾抵玩 ~
