Out of curiosity, I decided to compare the cropped image sharpness between the D800 and X-E1 on a tripod mounted 70-200/4 AF-S @ 200 mm shot wide open with a USAF resolution chart. The X-E1 was mounted on the lens using the Kipon Nikon G adapter. Focus was adjusted to critical sharpness on each body. Both were set for auto WB, ISO 400, spot meter, JPEG (L). There was no post processing in either image. Sensor resolution is stated as 16.3 MP on the Fuji and 15.4 MP on the Nikon (DX mode). The results were better by two groups (1,5 vs. 1,3) on the Fuji and it's auto white balance did a far better job in correcting the warm tungsten light. Taking into account test distance, resolution translates to 56 lp/mm on the X-E1 and 44 lp/mm on the D800. While, I expected the lack of ant-alaising filter to improve resolution, I wasn't sure by how much. Fuji also seems to do a much better job on auto WB and I wonder if it's due to their departure from the conventional Bayer array or just better WB since Fuji's have always had a good reputation in that department with their previous DSLRs. The X-E1 is on the left and the D800 on the right.
