我知道CCD的size是會影響景深, 同樣光圈的情況下, CCD越大景深越淺, DSLR可做淺景深過DC. 但實際分別有幾大? 有數可計嗎?
eg. KM A200 vs Olympus E-300 vs Kodak Pro SLR/n
可post D 相嗎?

去呢度計計吧.

Thx. But I don't really understand the difference of these term:
Hyperfocal distance for this lens/aperture combination
Near limit of acceptable sharpness
Far limit of acceptable sharpness
Total depth of field

CCD越大景深不會越淺.
我之前問過類似問題.
DSLR可做淺景深過DC,是因為dslr可以用換鏡頭.
用長焦距/大光圈鏡頭.

所有鏡頭焦框越長景深越短，光圈越大景深越短。

DC及鏡結構不同DSLR,DC鏡尾距離比DSLR近光量大而光圈口徑不需太大已有f2.8,但光圈口徑小因而景深闊,只有用長焦補救,本人用A1加原廠增倍鏡在135焦距後可減短景深在200段大頭可有3至６寸景深,但與135鏡1.4比可收到1寸仍有不及.

Is really useful. I think I understand now. Thanks.
