Reverse EFS Lens firmware
« on: November 15, 2017, 02:27:11 AM »
Lens firmware of EF-S 55-250 and EF-S 40 f2.8 are downloadable on Canon offical site ,
with great help from a1ex , i tried to analyze 55-250 firmware , but no progress ,
the BIN seems to be encrypted or i was wrong somewhere.
Now start to analyze Lens firmware of Sigma 24-105mm f4.0 .
