Sigma Tele Converter for TC-1411 L-mount

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 1.4X Telecomverter TC-1411. ◆Compatible lenses: 100-400mm F5-6.3 DG DN OS | Contemporary, 105mm F2.8 DG DN MACRO | Art ◆Focal length/magnification: 1.4 times that of the master lens ◆AF compatible: AF shooting is possible at all f-stops and focal lengths. ◆Dust and splash resistant: Equipped with the same dust and splash resistant specifications as the Sports line. ◆100% inspection with Sigma's proprietary MTF measuring instrument "A1": Until now, the performance of teleconverters has been measured using MTF measuring instruments that use general sensors, but we have independently developed the MTF measuring instrument "A1" using a 46-megapixel FOVEON direct image sensor, similar to the lenses in the SIGMA GLOBAL VISION series. This makes it possible to inspect even high-frequency components that could not be detected before. SIGMA TELE CONVERTER TC-1411 and TC-2011 are shipped after being fully inspected with this "A1".
