【SONY 16mm f2.8 SEL16F28】 + 【Ultra Wide Converter VCL-ECU1】 Set This is a set of the SONY APS-C format E-mount single-focus lens 【SEL16F28】 and the ultra-wide converter 【VCL-ECU1】. The SEL16F28 is a wide-angle lens equivalent to 24mm in 35mm format. By combining it with the VCL-ECU1, it functions as an ultra-wide-angle lens with a focal length of APS-C 12mmF2.8 (equivalent to 18mm in 35mm format) and a diagonal angle of view of approximately 99°. The horizontal angle of view for APS-C is almost 90°, and as a guide, it is possible to shoot within a range of almost 90 degrees with both hands spread out. I think it is the perfect lens for Vlog cameras such as ZV-E10. 【Product Condition】 It is a fully functional product with little use. It has only been used a few times after purchase and has been stored in a dehumidified storage, so there is no mold or clouding. 【Included Accessories】 All items shown in the photos.
