Laowa 1.4X FF Expander is tailor-made for the OOOM to expand the coverage from Super35 into full-frame without affecting its image quality.
**There will be a 1-stop light down and 1.4x impact on the focal range, making OOOM a 35-140mm T4 lens. A quick switch button is designed on the OOOM to allow easy conversion of focal length & t-stop scale.
