AF200S on Panasonic LX7

Just snapped up a mint condition Pentax AF200S flash for £8 from my local second hand camera shop. I tried it on my Panasonic LX7 compact. I thought I would have to use the camera and flash on manual to get correct exposure, but using aperture priority and flash on auto gives spot on results. Also by using the Pentax flash on the camera, with optical slaves I can now use multiple flash with the LX7. Wonderful.
