Recall that the best fixed focal length lens Fujifilm X system tested in this way achieve results at the level of 73-75 lpmm and decency level is set at around 42-43 lpmm. So let's see how against this background that present themselves tested lens performance. The corresponding graph showing MTF50 values ​​obtained for the center and the edge of the frame is below.

As far as the center of the frame, already at the maximum aperture the result is great, because it reaches nearly 72 lpmm. At f / 2.8 Fujinon 2/90 achieved a record value of 78.5 ± 0.6 lpmm - the result of which has not yet obtained any other lens arrays tested on Fujifilm cameras. That should be enough for the whole comment.

As far as the edge of the frame, then we have no reason to complain, although in comparison to the great city, coast already so not impressed. The more that in telephoto that class should not be so wide disparity between the center and the edge of the frame.

Pros:

• rugged and sealed enclosure,실링된 튼튼한 경통
• sensational picture quality in the center of the frame,중앙부 화질은 끝내줌
• good image resolution at the edge of the frame,주변부 화질 우수함
• small longitudinal chromatic aberration,축상 색수차 적음
• minimal lateral chromatic aberration,색수차 적음
• imperceptible spherical aberration,구면 수차 거의 눈에  띄지 않음
• almost zero distortion,왜곡은 사실상 없음
• great corrected coma,코마 수차 양호하게 보정됨
• low astigmatism,비점 수차 적음
• nice appearance blur,흐림 효과 좋음
• moderate vignetting,비네팅 무난함
• quiet autofocus and customs.빠르고 정숙한 AF

Cons:

• High price,비쌈
• work against bright light after stopping down the aperture leaves much to be desired.조리개 조였을 때 역광 성능 아쉬움
