Our last few comments concern the 660 Ti's 192-bit memory interface. Our

发帖数: 1077 | 35 出两台，都配上至少不逊于7D的对焦系统。
一台低像素，高感，宽容度突出，高感至少比5D2提高2档，最好能够提高3档，ISO6400和5D2 ISO800成像相当，配个大光圈镜头，基本上啥都能拍了。高光宽容度至少提高半档。摄像功能有很大提高，最好用类似于GH2的像素合并技术，在resolution, moire, aliasing等方面有质的提高，最好还有1080/60P mode，以及更高的码率可供选择，可以一统DSLR Filming领域。
一台高像素，去掉低通滤镜，满足专业studio对于resolution的要求。
这两台的售价都应该在2500-3000之间。
如果真是这样的话，我肯定买一。没有低通滤镜的高像素机型很赚眼球，但是对于非专业studio用途而言，没有什么实用价值。而且，没有低通滤镜，造成的moire问题，使得video几乎没发用。 |

The Fuji X-Pro1's image quality and handling are astounding. AF and overall
speed is twice as fast as the X100, and the magic sensor, which plays tricks
to eliminate color moiré problems so it can dispense with the anti-
aliasing filter, are astoundingly sharp —sharper pixel-to-pixel than
anything from a DSLR and about the same —maybe better than the LEICA M9. |

for the 5DmkIII. However, hearing about resolution complaints for 5DmkIII
video, I think they bin pixels before read out. This improves noise and
