I test 17-40L with 24mm 1.4 and 24-70 2.8 at 24mm. It won !

上面果位師兄
個網測試果支係18-55 (300D Kit Lens )o黎喎。
-----------------------------------------------------------------
首先講明小弟未用過EF-S 17-85mm f4-5.6 IS USM。
不過小弟覺得依支鏡可以用方便o黎形容，
17-85乘落350D度相等餘27-136mm，
係一支好標準o既Kit Lens，
若用o黎影風景或生活照一般都已經好夠。
而IS 用於手持室內及夜拍時亦都係非常實用，
由其是夜拍通常要收細光圈。
不過據聞依支鏡響17mm Wide 時會有黑角，
係唔係就唔肯定。

EF 17-40mm f4.0L USM 係小弟一支常用o既鏡，
成像方面係有非常高o既表現小弟可以肯定，
L 鏡響小弟身上代表"忠心"
值得挑剔o既就係17mm Wide 時o既變形，
我諗17-85 IS 都有同樣問題，
要解決依個問題我諗要響構圖方面下唔少功夫，
見過唔少大師都可以將變形變成突出，
依樣小弟真係未到咁高層次。

"不過據聞依支鏡響17mm Wide 時會有黑角"
That is confirmed. I used it but already sold.
17-40 qaulity is better but lose the range.

我支17-40冇黑角喎!

17-40落1.6x crop 都用唔哂支鏡既成像圈，當然無喑角啦！

其實17-85廣角端全開光圈會有小小喑角，收到f/5.6-8成像都不錯，小弟買過支凈係for室內私映，所以不須開大光圈映，落1.6x crop就一鏡有齊廣角/中長距，仲有埋IS，用落真係好易被縱壞！不過室內映就當然唔夠定焦快．如果未中L同定焦毒，呢支就夠用架喇！

The 17-40mm gives no dark corners on 1.6x crop factor cameras. I haven't put it on a full size 35mm camera, so I don't know whether the dark corners are present in this situation.
