所以发这帖楼主只能拿到两罐1993年的……

RAW压缩算法的问题。。。。跟相位对焦点没有半毛线的关系。。。。

Z7用的类似D5X00系列的RAW有损压缩算法。  大幅度提高暗部就会出现条纹。。

在意这个的用无压缩RAW就行。。。。

就这屁大点小事也要扯倒闭。  一看就是隔壁※※发的黑贴。。

一看楼主注册时间。 果不其然。。。。

我从SONY的一个PDAF对焦（双核像素）专利文件中找到一点儿相关的东西，供参考:

登录后可直接显示原图

我用红色画出来的部分，文件里写的功能是：

In the AF line Lif, as depicted in FIGS. 8 and 9, every other
opening OP (FIG. 7) of the first metal 41 formed in the
normal-pixel line Ln is light-shielded by a first metal 44. In
other words, in order to bring adjacent AF pixel pairs 11f
closest to each other to increase accuracy of the phase differ
ence AF, the light-shielding portions LS, each being provided
between adjacent microlenses ML in the AF line Lif, are
arranged with a space equal to a space ofevery other pixel in
the arrangement of the normal pixels 110 disposed in the
horizontal direction in the normal-pixel line Ln. Specifically,
a portion OQ (FIG. 8) where the opening OP is formed in the
arrangement ofthe normal pixels 110 depicted in FIG. 7 is
blocked by the first metal 44, on which a black color filter
(black filter) Fb is disposed every other pixel. The reason for
disposing the black filter Fb on the first metal 44 is as follows.
That is, if the upper surface of the first metal 44 is exposed,
light incident from the interchangeable lens 2 may be
reflected to cause a ghost flare. Thus, the black filter Fb is used
to absorb this reflected light, thereby suppressing a ghost
flare. Therefore, in each AF pixel pair 11f of the present
embodiment, above the photoelectric converting units PD in
a pair, the light-shielding portion LS is disposed, which has
two light-shielding areas Ea and Eb made ofthe first metal 44
and the black filter Fb formed on the portion OQ for light
shielding of light beams of the Subject passing through the
exit pupil. As such, with light-shielding by the black filter Fb
and the first metal (metal layer) 44 in the light-shielding
portion LS, appropriate light shielding can be performed in a
simple manner. Each AF pixel pair 11f is provided with one
microlens ML interposed between the two light-shielding
areas Ea and Eb extending toward the center from an upper
portion of both ends of each of the photoelectric converting
units PD in a pair.

蓝色线，是我画的，会不会有非正常从镜头进来(比如镜筒反光)的光线照射电路部分导致电路异常工作呢？  FYI.

对，D700也有类似的问题

wzdgp 发表于 2018-10-2 11:55
洗洗睡吧，这个题目太唬人了，还好比我的d700好。

这两个对比还是z7好一些，虽然有条纹。

50笑百步，R的色带比Z只多不少。

输给D850不丢人
