Canon SPEEDLITE EL-10 Flash

I bought this as a pocketable Canon flash to use with R5 MkII and R6 MkII cameras. I also own the EL1, EL5 and the EL100. The power is good enough for most direct flash use and is just about OK for bouncing off of low ceilings and nearby walls. It works well with the superb ST-E10 transmitter and I am pretty pleased with my purchase. The only annoyance is the 'pop' noise it makes when you fire it. It is quite loud compared to all of the other Canon Speedlites I own and have owned.
