Infra red with the A7ii

[monopix]

Anyone else tried using an IR pass filter with their A7x? Just tried it today and, although exposures are long, it does a reasonable job. I assume there is an IR blocking filter built into the camera but it doesn't block 100%. I used a R72 (720nm) filter but would be interested to know if a 680nm filter might be better without losing any of the IR effect.
