Until now, the performance of teleconverters has been measured using an MTF measuring device with a general sensor, but as with the lenses of the SIGMA GLOBAL VISION series, we have developed our own MTF measuring device "A1" using a 46 megapixel FOVEON direct image sensor. It is now possible to inspect high-frequency components that could not be detected before. SIGMA TELE CONVERTER TC-1411 and TC-2011 are inspected with this "A1" before being shipped.
