請問點解單鏡機唔可以拍到movie ??
thx ~~

[pingu_hk]

This is NOT a low B question!

1. DSLR use focal plane shutter (DC uses "shutter between lens" design) which cannot release so frequently.

2. all DSLR has high pixel size, so CCD gets very hot when taking movie [this is the most difficult problem to solve)

3. data bandwidth problem, so much data to send to computer of DSLR
(this can be partly solved by taking only some portion of the DSLR CMOS/CCD to record movie)

The OM / panasonic is doing a DSLR model with movie taking function, it will soon be released, the have solved the "CCD heating problem" while capturing streaming movie, but the "lens shutter problem" have not been solved, may be they will solve soon.

(BUT beware if u have such DSLR, the CCD of DSLR will burn faster than non-movie taking CCD)

[CORRECT ME IF I AM WRONG, thank you very much]

thx ~~
好詳細呀...

想要DSLR拍movie係咪要求太多呢?要塊shutter一秒開合30次,就算做得到你都唔會立亂用啦。

冇記錯頂級機都係1秒唔到10張, 不如果真係去到30張, 條片就真係超高清

我對呢樣野又有另一個睇法...

我覺得其實要d公司做到DSLR拍到MOIVE是有可能的,
(佢地果D所謂"技術極限"既問題, 我就唔完全相信喇)
即係
如果DSLR拍到MOVIE, 因為鏡頭關系,
所以可以做到手動變焦, 對焦,
鏡頭要幾鏡有幾鏡, 又有景深,
如果拍得叻, 都差不多電影咁既FEEL啦
(當然仲有收音果D未計啦)

好喇, 以上既野成立左喇, 咁問題就係

DV機仲有邊個買?....=,=

DC仔又拍片, 分分鐘解像度仲高過DV,
DSLR都拍埋片....
就算DV機, 都唔係部部俾您有手動對焦環...

SORRY...講得比較亂, 而且我識既野又唔多,
都係分享下咋~~~

講錯咩野任插^^"

"The OM / panasonic is doing a DSLR model with movie taking function, it will soon be released, the have solved the "CCD heating problem" while capturing streaming movie, but the "lens shutter problem" have not been solved, may be they will solve soon."

1. NO company D-SLR roadmap have movie function.!

2. SONY CMOS also have no "CCD heating problem" !

3. No ANY "lens shutter problem" in electrical shutter!!

[ELIZABETH]

DSLR have NO advantage to have movie functions!

1. HDV is produce very high 1080 HD quality on a tiny CCD!!!

2. video camera always have bigger zoom than DSLR because of CCD size

3. DSLR large CCD/CMOS need powerful downscale CPU and video process


at last, but a DV, miniDVD, miniDV camera to capture video!!!

民用頂級機1/3" ccd, hd video都係1920x1080, 得200萬pixel咋喎, 單計ccd密度, 一隻500萬dc仔都贏佢, 就算最新超高清, 3840x2160都係600萬pixel, 但係賣緊過百萬喎. 就算dc仔/dslr拍得到, 都唔會拎出來賣啦, 收得你幾錢先?

哈哈，又係呢類問題

永遠有兩類人爭吵

1。保守派：dslr 只係要黎影相，唔應該有 video 功能，而且一定要用 viewfinder 影相，唔可以用 LCD 對焦，有呢 d 功能就唔係 dslr，係 dc。

2。改革派：點解唔得？功能越多越好。

耐唔中就會有呢 d 問題出現 ~~~~~ 講真，我偏向改革派，科技進步，好的演變對用家有利，何必將ｄ野規範到一成不變。

好似之前拗左好耐 DSLR LCD 對焦，終於都比 OM 打破左。睇下幾時 DSLR 可以拍埋 MOVIE 喇。始終有需求就有人研發。

駛鬼咩, canon出隻efs mount, 用apsc ccd, 冇反光鏡o既cam, 唔會太難o者, 不過用o個條友可能媽媽聲, 批住碌大白影野, 光圈又唔夠大.

[hkres]

咁咪即係 S仔 R1 ~~~~~~~~~~

順口問句，用 APSC CCD + 大白影野,點解會光圈又唔夠大？有乜關係？

[kingkonghk]

求其一架jvc雞雞地都15x zoom, f1.2啦, 如果大ccd要做到咁, 仲唔係要托碌大白出去影咩, 大白都唔得添呀, 光圈都唔夠人勁

[hkres]

咁又唔係喎，拍 V 同影相唔同，係偏暗環境下，影相要 1/15 秒時候，拍 V 都做到 30FPS。
