This was an interesting experiment: off-camera flash with the Ricoh GR.
The GR has a leaf shutter, which doesn't suffer from the flash synchronization issues that an SLR's focal plane shutter has. This was taken at f/8, 1/1000s, and iso100, under-exposing the overcast mid-day light by three stops. An Olympus FL50 flashgun, which is fairly powerful for an on-camera unit, came out of retirement for the occasion. I could have used a TTL cable to trigger the flash, but I used an optical remote instead.
It's a little tricky to make it all play together, given that I was hand-holding both the camera and flash while trying to manage their manual settings. This one of only two photos that worked. But the purpose of the effort was to prove the technique for another day when I plan to photograph a new series.
