Fringer has been releasing firmware update pretty rapidly and the above video pulled by Zed has been updated with FW 1.6 and the Sigma 18-35/1.8, while below we see how quickly you can shoot 30 Canon EF mount lenses. Now Firmware 1.7 is available with 4 optimized lenses and some additional fixes.
2018/4/30 Version 1.70
1. Fixed the issue of failing to identify some of SIGMA 35/1.4 Art lenses and activate PDAF for them.
2. Re-optimized SIGMA 35/1.4 Art to improve its PDAF accuracy
3. Added following lenses to the tested and optimized lens list:
1) EF 200/2.8L II + 2X
2) EF 500/4L IS
3) EF 500/4L IS + 1.4X
4) TAMRON 24-70/2.8 G2
4. Fixed compatibility issues with X-A5 camera. Be noted, since X-A5 is equipped with a none X-Trans CMOS, its AF performance is poorer when using EF mount lenses. Please use MF mode if necessary.
