In imaging-resource, the date of SONY a700 picture is " 2007:09:20 10:25:54 "
Kind of old.

They should update this picture with V.4 firmware configuration.

最近有幾個換DSP導致高ISO性能大幅提升的例子
像Olympus在EP1上採用的TruePic V
Canon在50D, 500D, 5D2上採用的Digic IV等等....
如果Firmware改成V4就能起死回生
那你應該趕快去跟SONY報告一下, A900也趕快升級一下才是, 不然跟5D2, D3X差太多了
事實上你可以看到A900以後的相機
譬如A330, A380, 跟A300, A350比只是抹更大, 雖然雜訊看起來少了, 但是畫面也更糊了
除非SONY從頭來過, 把那顆BIONZ換掉
否則我肯定不管V多少, 都不會有什麼改進, 畢竟抹雜訊的硬體電路都已經寫死了, 換firmware效果不大

It is true.
Sony needs to upgrade their DSP to newer version.
No matter how many BIONZ in a A900.
They only process pictures faster than single DSP but better quality.

V4 firmware just made a700 slightly better than V3. not enough
