老外的测试结果

Just upgraded the firmware and ran a series of tests (similar to previous ones with Christmas tree lights). I was easily able to duplicate the issue using extreme underexposure around the lights, and with the new firmware, I'm happy to report that I cannot find even a single black dot.

I ran the raw files through DCRAW using document mode (not demosaiced) and examined the area around the lights to look for any anomalies (pixels below the black threshold) in my astronomy image processing software (MaximDL) which shows pixel statistics for selected areas. There were none to be found, whereas in previous tests, there were hundreds.

I also looked for signs of obvious "patching" of black areas, possibly where color data would have been wiped out on the right side or some kind of smearing. I could find none. The bayer mosaic looked symmetrical around the light.

Of course, the JPGs also show no black dots either.


I've taken about 10 pics with a wide swing of conditions. I'll try some more this evening, but I'm confident this already small issue is resolved. If I find otherwise, I'll post here.

等国内测试结果 新固件的相机什么时候能上市

看遍各大论坛, 似乎

1. 黑点问题己经完全解决;

2. 对画质, 高IS0表现没有任何影响----看不出有任何变化。

新进的5DII.
斗胆上几片.请点评.

冲完电马上升级！

终于。。。终于。。。终于有人上片了！

哪一支镜头？？？

黑点问题解决了就好，可以准备入手了

ISO12800。。。

躁点着实不少

ISO 12800, 这样也算可以了。躁点不可能没有。

我估计我不会有勇气用这么高的ISO。

3200可接受，6400基本可以接受，12800小图可以接受。

黑点几乎不成为问题。
