我都係用開dc影呀仔, 佢非常活躍, 經常連焦都未對倒佢已經走開左, 有時完成對焦但因為快門時滯問題, 一樣係俾佢走開左...

後來轉左用dslr, 對焦快而準, 又可以做出淺景深效果, 跟住就中左毒

d40或者400d, 都係light weight and small.

Re: want fast 快門camera, must need 單鏡反光机?

Kit lens 即是套裝跟機的鏡, 現在D40的kit lens應該是18-55, 約值HK$800.

D40 kit lens 影的相都會好過DC, 不過如果真係想快, 又唔想預太多budget, 就要買定焦 50mm f1.8, 賣緊約$800, 不過無貨, 買二手過左保養期都要$600. 但可惜D40用唔倒.

Faster shutter because of 大光圈.

在一些光線不充足的地方, 例如 Kit 鏡光圈最大只有f5.6, Shutter Speed 是1/30s, 如果同一環境, 換上大光圈的定焦鏡, 光圈可開到f2 (已經要收一收光圈了), 其餘全部setting不變, shutter 會快到1/200s.

Re: want fast 快門camera, must need 單鏡反光机?

光圈越大(數字越細), 更多的光可進入相機, 從而快門可以更快, 但同時景深又會越窄.

我試兩張俾你睇.

第一張是用 f1.4 影的, shutter speed 是 1/30s, 可見到圖中只有中間部份清楚;

第二張是用f5.6影的, 所有setting不變, 但快門跌到1/2.5s, 但同時景深闊了, 圖中的字都可以看清楚:

Re: want fast 快門camera, must need 單鏡反光机?

你想影一個郁得快既物體,快門快只可以將個影象拍下來但唔代表個影就喺你想要的影象。

DSLR 比DC快的並唔係快門速度而係快門反應,由你按快門,部機對焦、對焦完成,開快門,曝光、關快門整個過程都比DC快。

我之前在這裏都講過我的一次經驗,我用DSLR和另一個家長用DC站在一起拍一個小朋友跳高捉住一隻掛在半空的玩具,我可以拍到小朋友跳起,捉住玩具,着地及離開,但用DC的家長,只拍到一條掛在空中的線......。

當然,比我用DC我都可能影到小朋友捉住玩具,但就冇乜可能影晒成個過程,除非改拍video(DSLR係唔可以拍video)。

DC同DSLR 各有長短,邊樣合你,要你自己先知。

if i want my bb to smile at the camera, i have to press the button BEFORE i do something to make her smile. if with flash, my DC is even slower.

Re: want fast 快門camera, must need 單鏡反光机?

我係指用同一部DC我都可能影到小朋友捉住玩具,因為我可以事前對焦,等小朋友差不多捉住玩具全按快門,咁幾會會大好多,練多幾次,熟識器材特性,你都得架。

Re: want fast 快門camera, must need 單鏡反光机?

if my sony T9 specs said:
曝光模式: 1. 不支援光圈先決
2. 不支援快門先決
3. 不支援手動曝光

快門速度: 1/1000 至 1 秒,不支援 B 快門

which means i cannot set anything to capture bb moving (faster shutter) or take 淺景深picture right??
