... Superb illumination - also usable for bigger sensors - a field of approx. 40 mm diameter is illuminated by 100%. The working distance from he M48 thread of the corrector is 111 mm.TSRED102 - 2" Field corrector and reducer
... The focal length is reduced from 714 mm to 571 mm. The speed is improved from F7 to F5.8. The exposure times are appropriately reduced. We recommend the reducer for sensors up to 30 mm diameter, like the ones in APS-C format. the working distance from the T2 thread of the corrector is 55 mm.Delivery contents:
