比red好????
高感性能比RED好太多了, RED的优势是分辨率,RED能保持画面相对纯净也就是 ISO 1600的水平,到 ISO 6400时,画面早就不能用了。
英国专业视频的权威网站: HD-warrior对 PMW-F3的画质评价是这样的:
http://www.hdwarrior.co.uk/category/hdcamcorders/sony-2010/
I have to agree with Alister’s findings that this camcorder even at 18db is unreal, I have never seen a camcorder to date that will give you usable pictures at 18db and if you are shooting low light moody productions this camcorder will fit the bill.
在他们看来,还没有见过任何一部摄影机能在 18dB的增益下,拍摄的画面依然能达到可用的程度, PMW-F3开创了这个先河,在 18dB增益时,所拍摄的图象依然完全可用。(可见 F3的动态宽容度之强悍)。
Alister “One of the tests I did with the PMW-F3 in Oslo was to look at the cameras noise and grain. There was nothing sophisticated about the test, simply shooting a few clips with the gain set at 0db, 9db and 18db. You can see the results on the left. I had to blow up the image by 200% as at 100% you could barely see any difference
而且,HD-warrior也一再强调了, PMW-F3所拍摄的画面,在 0dB、9dB、18dB时,图象放大到 100%竟然看不出差别,只有当放大到 200%时,才能分辨出差异(足以证明 PMW-F3的图象纯净度有多么强大)。
