I have owned all these items since new. 1. Sony 16mm f2.8 (SEL16f28) E mount. 2. Sony VCL-ECU1 Ultra-Wide Converter. 3. Sony VCL-ECF1 Fisheye Converter. All have been used on my Sony A6000 and would be suitable for any crop sensor (APSC) 'E' mount camera. Originally designed for the 16mm f2.8 I understand the converters can be used with the Sony 20mm f2.8. Items in excellent, unmarked 100% working order with no issues. 16mm f2.8 incls end cap and lens cap, unboxed. Both converters (as new) boxed with end caps and lens caps. These converters are not toys costing upwards of £100.00 each they are a highly cost effective way to maximise the use of the 16mm f2.8. VCL-ECU1 Ultra-Wide is 18mm on APSC cameras. VCL-ECF1 Fisheye is 15mm on APSC Both converters:- Retain the f2,8 aperture of the 16mm lens. Have no effect on autofocus performance. Have no effect on exposure. There are newer versions VCL-ECU2 and VCL-ECF2. The only difference is they are black bodies.
