摘要是,5D3的3200相当于5D2的800,5D3的高感表现纯来自于芯片技术,不是加味精的
。
考虑到1Dx样图都不敢放,个人认为这是严重吹水。佳能做芯片降噪是比索尼牛,但完全
不加味精,是绝对拼不过D3s,D4之流的。
"Westfall indicates that at moderate-to-high ISO sensitivities, the 5D Mark
III has about a two-stop advantage over the 5D Mark II. As an example, he sa
ys, an ISO 3200 picture shot with the new model has roughly the dynamic rang

He emphasizes that the bulk of the higher ISO image quality improvement come
s from enhancements to the image sensor itself, as opposed to heavier-duty n
oise reduction being applied once the picture has been converted from analog
to digital form. The only camera from Canon that will beat the image qualit
y of the 5D Mark III at higher sensitivities, says Westfall, is the EOS-1D X

其实黑面大师这个说得很有道理

與其說這幾年感光元件的製程有進步,讓高ISO有進步
還不如說抹JPG的技術跟製程進步了~
片幅大小的差距,一開RAW檔就無所遁形啦~
有這想法,其實已經很久了,只是今天看到 Dpreview 的 G1X 測試圖
心血來潮的去把個片幅的機種開來比較一下
果然現實還是殘酷的阿~
網路上有得的測試報告,每次發新機就把可用ISO說有提升一級
其實是不是這樣,只有消費者自己判斷啦~多看看,多比較,多思考,不會錯的囉~^_*
