其實大家沒被騙：領匯私有化與經濟理論
很好的文章。每有這樣的情況，我都不禁要想：香港人對經濟理論是一知半解。
自由市場的優點有歷史基礎，但對自由市場的追求卻很大程度上是源於經濟理論。大家都耳熟能詳自由市場能提升效率、「造大個餅」，進而惠及社會各階層。但在實際操作上跟理論的要求大有出入。
一， 提升效率 = 大部份人會受惠。香港有很多人的想法可以歸納為：自由市場 -> 高效率 -> 自然惠及社會各階層。其實這個想法根本無經濟學理論基礎。
「自由市場下有高效率」的基礎是福利經濟學第一基礎理論，「高效率可以惠及所有人」則是福利經濟學第二基礎理論—-對，就是香港最知名經濟學家說沒用的那兩條理論。要注意的是，第二基礎理論並沒有「自然」一詞，反而有「可以」兩字。「可以」代表甚麼呢？就是有辦法惠及所有人，但那辦法不一定會自行實現。說直點，由政府來作資源再分配，也可以是辦法之一。
二， 私有化 = 自由市場。這可是真是天大的錯誤。任何經濟入門課本都會告訴你，若商家壟斷就不算自由市場。雖然相比公營機構，由壟斷者經營還是有可能會得到效率提升，因為壟斷者想將利潤最大化。但剛說過，高效率本身並不代表大部份人會受惠。道理簡單：無競爭壓力，我幹嗎要給你便宜？
領匯的私有化就是創造壟斷遠多於回歸自由市場。成個屋邨商場我嘅，連隔籬邨都係，你唔係到買賣可以去邊？其實大家沒被騙—最起碼，用真金白銀支持領匯上市的五十萬市民並沒有被騙。要賺錢、要賣個好價錢，當然是弄個壟斷者好。領匯年年加租，回報豬籠入水，外國大型基金亦垂青，這不正正代表領匯達成了其成立背後的真正目的嗎？
De-clicking Canon FD lens to get stepless aperture
Dedicated video lenses usually feature stepless aperture to allow for smooth adjustment of exposure. Most still photography lenses, in contrast, feature stepped aperture adjustment. This guide demonstrates how to “de-click” Canon FD lenses to get stepless aperture.
Before you continue, note that
- De-clicking is easy. All you need to do is to unscrew the rear and take out one or two things.
- The process will not introduce dust into your lens—the optical assembly is sealed in one piece inside the lens.
- There is a “cheat” that gives you continuous aperture adjustment without the hassle of opening up the lens. All you need to do is set your lens to the smallest aperture, then turn the ring on the FD adapter. The downside of this cheat is you do not have any indication of which f-stop you are at.
With that in mind, if you still believe de-clicking is useful—and I personally do find that being the case—here is a quick demonstration on how to do so.
1. Take apart the lens from the rear and remove parts that cause un-smooth movement
You need to remove the two parts indicated by the blue arrows if you want the aperture ring to rotate smoothly. If you can stand the un-smoothness, however, you can keep the parts on—with the parts on, step 2 alone is actually sufficient to give you stepless aperture.
2. Remove the piston
On lens such as the the 28mm—in which you lock by rotating the whole lens—the piston underneath the aperture ring provides the click. Remove the piston de-clicks the lens. If you have kept the two parts on in the first step, you can now re-assemble the lens.
If instead your FD lens locks with a rotating metal ring, you will need to remove the two ball bearings inside the aperture ring.
3. Removing the spring holding the aperture selector
At this point if you re-assemble the lens without the jiggering parts, you will notice that the aperture bounces back when you try to set a small aperture. This is due to the spring mechanism used in FD lens’ aperture control: the aperture ring is actually only capable of driving the aperture in one direction; reverse movement is driven by the spring holding the aperture selector. Removing the spring solves this issue.
4. Linking the aperture ring to the aperture diaphragm
Because the aperture ring is designed to only drive the aperture in one direction, you need to manually link the aperture ring to the diaphragm. Here I used a short polyester thread, lopping around the coupling pin on the diaphragm and held underneath the link on the aperture ring. Make sure the aperture size match up with the f-stop indicated on the aperture ring.
If your FD lens locks with a rotating metal ring, you will be lopping around the coupling fork instead:
5. Re-assemble the lens. It’s done!
I have the same view. It’s not that demand for journalistic photo has decreased, but rather the supply has vastly increased, thanks to ever more amateur photographers with ever better skills and cameras. The result is an increase in journalistic photos, but a substantial decrease in professional photojournalism.

我相信假如擁有奴隸合法，今日嘅香港非但唔會有意廢除，甚至有可能以作為「最大奴隸交易港」而自豪…
婆：「個商場叫咩話？」
我：「APM。」
婆：「ABM？」
我：「A*P*M。」
婆：「ACM？」
我：「…下次都係我代妳叫的士。」
結論：希望商場嘅中文名要放多啲當眼處，用晒英文老人家好唔方便。
范 徐 麗 泰 ： 參 選 與 否 看 民 意 無 悔 支 持 唐 英 年
全 國 人 大 常 委 范 徐 麗 泰 說 ， 支 持 唐 英 年 時 不 知 道 對 方 的 緋 聞 ， 但 無 後 悔 支 持 他 。 她 重 申 ， 參 選 與 否 留 待 民 意 決 定 。 她 出 席 中 大 座 談 會 時 被 問 到 對 六 四 事 件 的 看 法 時 說 ， 香 港 人 接 觸 的 資 料 來 自 外 國 傳 媒 ， 無 權 就 非 親 眼 見 的 事 作 評 論 。
范常委教我看凊，我們可以談論的事原來真的很少—當今世代誰都沒見過孔子、沒見過耶穌、沒見過恐龍、也沒見過反物質，所以這些事物我們渺小的人類通通都無權過問。要求這般嚴謹，可見常委崇高之教育理念。
一眾傳媒政客指責常委是機會主義者，其實亦是誤解了常委的智慧—絕大部份港人從未親眼見過范常委，他們根本就不應對她有任何意見。所以常委所說的「民意」明顯只是一眾小圈子選委。如此明言在先，常委不愧為真君子。
唐唐英英，鬥反智，你們還遠遠未到家呢。
