越來越懷疑到底支17-40L值唔值5千幾???
買左呢支野的人係點諗?

唔怪得二手區咁多人放啦?
會唔會D人一睇到個"L"就乜都唔理就買,但用後發現根本同KIT鏡相差無幾?
成日聽D買左呢支鏡的人講"L鏡色彩好好多啦,又sharp d",但到我自己親眼去睇同一個環境/光圈時的比較實際圖片,又真係分別唔大..........
可能係D人買左支比KIT鏡貴10倍的L鏡,死口都話質數好好多/顏色好好多/SHARP好多,等自己開心番D??

我好想講, 只係唔敢開口 >_<
可能 Canon DSLR 一路以來, 只靠 RAW 再後制, Jepg 直出就不外如是
正如此, 已改買 Sigma 18-50mm EX f2.8 抵好多

咁..........兩位唔怕比人丙呀
不過敢言心聲亦係自由的
一路以來, 都只係覺得某類人在托市

[老叟]

係咩??咁大財團要重金搵個D人去托囉!!

Some western websites demonstrate the difference, no noticeable difference at wide end with small aperture (~f8 - f16), the difference grows with focal length. (18-55 kit lens vs 17-40 L lens)

墨魚怪.... thank you ..

you can give some people want buy it ...? is true or false

我相信分別還是有一點的,不過只係一小點.
個個測試都係放大到100%在電腦睇,分別也只是些小光學上的失真控制,平時睇相根本都唔覺.
17-40 f4一支咁既鏡真係$1000都唔值,焦段又短,光圈又細(大光圈就話難做得好啫,細光圈支支鏡都靚啦),買佢純粹為咗個L字.支鏡最大賣點只係L鏡之中夠平.

其實呢支17-40L 用係菲林機係幾好選擇(而且呢個range都少有), 用係aps size 就有d浪費了.

講翻sigma 近期d鏡真係幾成功, 又食到dslr 條水. 抵讚!

Conflict of interest: I own the 17-40L, and a few Sigma lenses.

You don't need to see the result to know the L lenses (in fact all )are over-priced. :-)

However, just to give some comments on the test:
If you look at the MTF of 17-40L:
http://www.canon.com.hk/tc/Product/Product.aspx?product_id=315&tag_id=10161

At 17mm, it performs significantly better at F8 than F4. Since most lenses perform at ~2 or more stops smaller than at wide open, if you perform the test at F5.6, you will expect result like this. The other lenses have wider max Av and if all are tested at F5.6, it may not be very fair.

Just my 2 cents.

咪o向度阻住D二手佬玩壓價啦！
此地不如久留。

呢度D人玩數碼玩上腦！！
17-40L 本來用嚮菲林機，點同支Kit lens只可以用在中低檔數碼機！！(因為佢[18-55 kite lens]用唔到嚮1DmkII and 1Dsmkii)

墨魚怪 if you do not like the L lens...sell it to me...I am willing to buy it at $2500 :P

and you can use this money to buy another ultra-wide angle lens la....

我唔敢講佢一定值5k幾，但無論成像，結搆，使用範圍，我覺得值得買

當然Kit lens我覺得佢抵玩！！成像唔錯就真！

[墨魚怪]

我只係想話比D未有此L鏡的人知道,其實此鏡用係1.6X機上(300D/350D.....ETC)畫質上用同其他CHEAP鏡比其實係差不多! 因有很多人用左5千幾買左支L鏡就以為好好多.......如果及早比呢D未有此L鏡的人看到這比較,佢地可能會將5千蚊買其他鏡呢! 我沒想過要壓什麼二手價.........我自己更加唔係2手佬呀!!

我都知道出呢個POST預左會咁啦,但心裡真的不說不快!!!

其實你個問題應該係"到底支17-40L用在1.6X機值唔值???"

要知道呢支鏡係超廣角Full Frame鏡，1.6X機要買支EFS 10-22先等同，咁你話值唔值?
