問吓有冇一些知料曾比較cmos與ccd之間在光位層次的表現
或各位影友對此有何心得呢?

[beancurdbean]

其實分別唔大, 以前有人話CMOS比較多noise, 但而家已經唔一定CMOS比CCD多noise
至於光位層次的表現, 主要睇pixel pitch大細 (sensor size 除 像素)
CCD/CMOS越大越好, 像素越少越好

sharp, 褲士同all達呢?

"And they "claimed" CMOS was also faster than CCD -> hence higher shot-to-shot time. "

咪亂吹, 相機最快咪一秒8張﹐CCD 電子訊號點慢都唔會有大影響

連拍速度係與處理器設計, filesize﹐儲存卡速度同最緊要的cache大小有關...

beancurdbean兄
即是說,在不足全片幅/135mm下光位層次的表現都是無法樂觀,
他們還要推出800万或1000万象素,噢!
5D所以很有市場價值乎.

如果像素少 (5D 12.8MP), 可以連1DsII 雖然FF 因為有17MP都fight低 (DR同noise)

不過當然一山還有一山高, 120, 645, 6x6.....大底會更強
不過因為(1)貴(2)慢(3)重(4)配件少, 所以遠遠唔夠135普及, 影樓同專業居多

support d2c

canon cmos data flow rate is faster than interlin and full-frame CCD(Kodak)

blowme,

u totally wrong
ccd need external AD converter,
but canon cmos is embedded with AD and amplify on cmos,
no any external electric circuit require,
this make cmos can fast because it process each pixel at same time,
but ccd need AD convert each line in a same time period!!!

如果自問對現時感光原件的分別不清楚，請仔細閱讀這個網站的文章。

CCD VS CMOS

這篇太好啦, 又齊
我之前話LBCAST係CMOS一種, 俾人話唔係, 又?唔番之前睇?資料

[小班長ErikoB]

lbcast睇番講番本單鏡 ge書(乜乜双周) 話係ccd黎obr
