Default Re: DSLR canon sl2 flash error 50

I did check the error 50 thing and and everything I came across, they were changing a capacitor. Just Youtube "canon error 50". However that doesn't help your focus issue. Did you try a known good lens?
The F74966A is a system control processor (MCU). I would guess there should be another IC between it, the flash and AF... besides the MCU needs programming?
