VILTROX EF-FX1 Auto Focus Mount Adapter Compatible with Canon EOS EF EF-S Lens to Fujifilm Fuji Mirrorless Camera X-T3, X-H1, X-T100, X-Pro2, X-E3, X-T2, X-T20 Series

Recieved this product and updated the firmware to ver. 2.29 and it was terrible and the lens, canon 55-250mm stm, wouldn't stabilize. I emailed Viltrox and asked them for a copy of the 2.26 firmware since many message boards recommended it and Viltrox's customer support responded quickly and sent me the file. The stabilization works and it cut down the focus hunting significantly!

The newest firmware is said to support the X-T10. However, it cannot focus on my X-T10 with Sigma 18-35 /1.8.The design with the tripod hole is really good. And the aperture ring on the adaptor is indeed unnecessary.
