Advantages장점:

• sensational resolution in the center of the frame.중앙부 화질은 아주 좋음
• good image quality at the edge of the APS-C / DX크롭 바디 주변부 화질 좋음
• imperceptible longitudinal chromatic aberration,축상색수차 거의 없음
• small lateral chromatic aberration,색수차 적음
• no problems with spherical aberration,구면 수차 문제없음
• virtually zero distortion,왜곡 거의 없음
• moderate coma,코마 수차 무난함
• low astigmatism,비점 수차 적음
• nice appearance blur,흐림 효과 좋음
• little vignetting on APS-C / DX.크롭 바디에서 비네팅 적음

Disadvantages:

• the edge of the frame near the maximum relative aperture is clearly worse than those of competitors,경쟁 렌즈보다 개방 주변부는 확실히 떨어짐
• too high vignetting on full frame,풀 프레임에서 비네팅 너무 심함
• ring to focus could be better.초점 링은 아쉬움
