: Imatest Ultra-Wide Field of View Test Fixture 한 장의 차트로는 pre-distorted 차트(광각 렌즈의 왜곡을 대비하여 pin-cushion처리)를 활용하여도 160도 이상의 FOV에 대응하지 못합니다. 이 경우 e-sfr ISO center차트와 SFR reg차트(모서리 차트)와의 조합을 통해서만 정확한 평가가 가능합니다. 하지만 평가 환경 구축과 신뢰성 있는 세팅의 재현은 쉽지 않은 일입니다.(조명, 차트 위치 고정 등) 이에 이마테스트에서는 차트와 조명, 기구물을 포함한 평가 시스템을 도입하였습니다.

: Chrome on Glass SFRplus Chrome on Glass charts are uni-tone, have 10:1 contrast, and do not include a step-chart. This means that they do not support calculation of tonal response curves. The star pattern is strictly for use as a focusing aid, and is not intended as a testing feature (i.e., as a star chart).
