DxOMark于昨日公布了索尼α7IV的传感器得分,综合97分!DxO认为:

1、索尼α7IV由于采用了全新的3300万背照式传感器,因此在DxO的基准里得到了97的高分。这是包含中画幅相机,排名达到了第七的好成绩。并且紧逼α1的98分和α7RIV的99分。

2、在基本的感光度表现上,α7IV的动态范围和色彩还原度在低iso时有着不错的效果。

3、在各级感光度下,只有iso400时同α7III比较有着十分微弱的优势,其他各档下表现均差不多。这也可见α7III的优秀性能表现。

4、动态范围上,iso200之前的低感比α7III有着些许的改善,比较有意思的是增益iso的切换α7III是800,而α7IV却变成了400,而之后两台机器都基本一致。

5、在低感表现下α7IV同α7III都有着不错的成绩,两者也是相差甚微,仅为-0.14EV。

总的来说,α7IV的传感器十分优秀,得分也相较于α7III提高了1分。高像素的同时也保持了同α7III基本相同的画质。但是,在低感上却略逊于α7III。和其他的2000~2400万像素的机型比较基本保持了一致的水准。这也说明了α7IV的动态范围和色彩还原度是顶级的,97分也是个无可挑剔的得分。
